[2018] WASAT 2
General information, not legal advice.
State Administrative Tribunal (WA)
2018-10-04
Original judgment source is linked above.
The applicant is the owners of units in a strata development located close to the sea front in North Coogee.
The respondent was contracted by the developer to build the units.
A complaint was made by the owners to the Building Commission in November 2013 that resulted in proceedings in the Tribunal being commenced in early 2015.
The matters for determination were reduced through mediation or otherwise to six items of complaint some of which contained numerous parts.
Item 1 a complaint as to the finish on various steel items. The Tribunal was not satisfied that the building service in respect of all but the walkways was not carried out in a proper and proficient manner or was faulty or unsatisfactory.
Item 2 a complaint as to whether a top coat had been and should have been put on the Acrylic texture coat 'Coventry Coarse'. The Tribunal was satisfied it was not proper and proficient or was faulty or unsatisfactory of the respondent not to have applied a top coat and consider it necessary and reasonable that a building remedy order be made.
The applicant sought a building remedy order pursuant to s 36(1)(a) and as a consequence no costings in respect of the proposed remedial work was provided to the Tribunal.
The Tribunal informed the parties that in the event a monetary order was made it would order the respondent be liable for 30% of the costs of the remedial work. The terms of the building remedy order are to be subject to further submissions from the parties.
Item 3 a complaint concerning the dilapidated state of the timber soffits. The respondent alleged the dilapidated state of the soffits was due to a lack of maintenance on the part of the applicant.
The Tribunal found the condition of the timber soffits to be as a result of faulty or unsatisfactory workmanship and said it would make a building remedy order.
Issues of proportionality were live in this complaint and again the Tribunal determined that were it to make a building remedy order pursuant to s 36 (1)(b) it would order the respondent to pay 50% of the costs of the remedial work. The terms of the building remedy order are to be subject to further submissions from the parties.
Item 4 a complaint concerning the presence of rust or corrosion on the concrete soffits. The Tribunal is satisfied that the respondent's use of plastic tipped bar chairs in place of plastic bar chairs as required by the Building Code of Australia and the building licence was faulty or unsatisfactory work. The Tribunal was also satisfied that the repairs already completed by the respondent were not satisfactory and were required to be redone. The terms of the building remedy order are to be subject to further submissions from the parties.
Item 7 a complaint regarding water leaks in three areas, an apartment, two store rooms and around a swimming pool the later issue being as to the cost of repairs only.
The Tribunal was not satisfied that the cause of the leaks in the apartment and store rooms was due to the building service not being carried out in a proper and proficient manner or being faulty or unsatisfactory.
The Tribunal was satisfied that the respondent had been prepared to carry out remedial work to the leak near the swimming pool and therefore found the building remedy order to be for the costs provided by the respondent.
Item 15 a complaint about the decking around the various swimming pools in the unit complex. At the hearing the respondent's expert agreed the decking had not performed as it should and therefore was not fit for purpose. The cause of the failure of the decking was found to be more likely than not due to the installation of boards with a moisture content value exceeding those recommended which caused cupping and excessive shrinkage when it tried out.
The Tribunal preferred the evidence of the respondent in respect of the costings associated with the remedial work.
Item 22 the Tribunal was informed in the parties closing submissions that this matter had been resolved. The Tribunal will hear from the parties as to what orders should be made.

1 The applicant is the Strata Council, on behalf of the strata company of the 'Islands', an apartment complex (Strata Plan No 52597) located in North Coogee.
2 The applicant made a complaint to the Building Commission (complaint) under s 5 of the Building Services (Complaint Resolution and Administration) Act 2011 (WA) (BSCRA Act) in respect of alleged faulty or unsatisfactory building work or work not carried out in a proper and proficient manner by Pindan Pty Ltd, the respondent.
3 The Building Commission referred the complaint to the Tribunal under s 11(1)(d) of the BSCRA Act.
4 The respondent contended that a number of items in the applicant's 'Schedule of Complaints Requiring Determination' filed in the Tribunal on 5 April 2016 (Complaint Schedule) (Exhibit 1 page 16 - 18) were outside the scope of these proceedings and the jurisdiction of the Tribunal as they were different, or not the same as the complaints bearing those numbers in the applicant's original complaint filed in the Building Commission on 18 November 2013, or the same as those in the revised schedule of complaints filed by the applicant in the Building Commission on or around 22 April 2014.
5 The preliminary issue was heard by the Tribunal on 19 October 2016.[1]
6 At hearing of the substantive matter on 1 July 2017, the applicant sought to have an item of complaint that had been withdrawn re-instated. This application was dismissed by the Tribunal.
7 At the commencement of the hearing, the respondent submitted that what was meant by the description of the items of complaint was still not clear.
8 On 22 September 2017 both parties filed closing submissions and the applicant filed a draft minute of orders sought.
9 The Islands consist of two apartment buildings (No 21 and No 23 Ocean Drive, North Coogee), plus associated facilities. The buildings were both built by the respondent and completed in approximately March 2010. The strata plan was issued in May 2010.
10 The Islands was constructed by the respondent pursuant to a building contract with the developer, Stockland Development Pty Ltd (Stockland).
11 The Islands is situated in the City of Cockburn and was the subject of a building licence number BA 07/1447 issued by the City of Cockburn on 10 December 2007.
12 The apartments were sold by Stockland (including off the plan) to individual purchasers. Those individual purchasers (or subsequent owners) are the members of the strata company.
13 The applicant filed the complaint with the Building Commission on 18 November 2013.
14 The Building Commission acknowledged receipt of the complaint by letter dated 25 November 2013 and requested further information in order to be able to process the complaint. By letter dated 6 February 2014, the Building Commission informed the parties that the complaint had been accepted under s 7 of the BSCRA Act and that the complaint would then be investigated.
15 The applicant filed and provided to the respondent a report from the Master Painters and Decorators Association dated 4 February 2013 (MPDA Report 1) on a date prior to 17 March 2014.
16 The applicant filed and provided to the respondent a further report from the Master Painters and Decorators Association dated 6 June 2013 (MPDA Report 2) on or about 17 March 2014. Together MPDA Report 1 and MPDA Report 2 are referred to as the MPDA Report.
17 The Building Commission issued a Proposed Building Remedy Order (PBR Order) on 16 October 2014.
18 The Building Commission found that as the matter was of a complex nature and both parties had contested the PBR Order as proposed by the Building Commission, it recommended the matter be referred to the Tribunal.
19 The Building Commission referred the complaint to the Tribunal under s 11(1)(d) of the BSCRA Act. The parties have, through mediation or otherwise, resolved a number of the items. The unresolved items of complaint are complaint items 1, 2, 3, 4, 7 and 15 as set out at Exhibit 1 page 17.
20 The issues to be determined by the Tribunal are:
21 All following references to sections or parts of legislation are references to sections or parts of the BSCRA Act unless the context indicates otherwise.
22 Section 5 permits the making of complaints about a regulated building service matter in the following terms:
(1) Subject to the regulations, a person may make a complaint to the Building Commissioner about a regulated building service not being carried out in a proper and proficient manner or being faulty or unsatisfactory.
...
(5) The regulations may make provision as to
(b) any preliminary action required before making a complaint under this section.
(a) made in a manner and form approved by the Building Commissioner; and
23 A 'regulated building service' is defined in s 3 as:
(a) a building service carried out by a registered building service provider or an approved ownerbuilder[.]
24 After receiving a complaint under s 5, the Building Commissioner must make a preliminary decision whether to accept the complaint, or whether to refuse to accept it. Section 7 provides as follows:
(1) After receiving a complaint under section 5 the Building Commissioner must decide whether, and to what extent
(2) The Building Commissioner may make such inquiries as are appropriate to enable the making of a decision under this section.
(3) The Building Commissioner may refuse to accept a complaint under subsection (1) if
(a) the complaint is not made in accordance with this Act; or
(b) the Building Commissioner is not satisfied that the complainant has taken preliminary action prescribed under section 5(5)(b); or
(c) the complaint is made out of time as referred to in section 6; or
(d) in the opinion of the Building Commissioner, the complaint is vexatious, misconceived, frivolous or without substance; or
(e) the matter complained about is the subject of another complaint under this Act; or
(f) an arbitrator or other person or a court or other body has made an order, judgment or other finding about the matter complained about; or
(g) the matter complained about has been the subject of a previous complaint to the Building Commissioner that has been refused or in respect of which the Building Commissioner has made a decision under section 11(1)(a).
(4) Except as provided in subsection (5), if an issue raised in a complaint has already been dealt with by the Building Commissioner or a complaint about the issue has already been referred to the State Administrative Tribunal under this Act, the Building Commissioner may refuse to accept the complaint to the extent to which it relates to that issue[.]
25 If the Building Commissioner decides to refer the complaint to the Tribunal pursuant to s 38, the Tribunal is then empowered under those provisions as follows:
(1) If the Building Commissioner refers a building service complaint to the State Administrative Tribunal, the Tribunal may
(a) if the Tribunal is satisfied that the regulated building service that is the subject of the building service complaint has not been carried out in a proper and proficient manner or is faulty or unsatisfactory, deal with the building service complaint by making a building remedy order; or
(b) otherwise, decline to make a building remedy order.
(2) The State Administrative Tribunal cannot make a building remedy order requiring a respondent who is not a registered building services provider
(a) to do any work of a value estimated by the Tribunal to exceed the prescribed amount; or
(b) to pay any amount exceeding the prescribed amount, unless
(c) the order is made in respect of a building service that has been carried out by the respondent in contravention of the Building Services (Registration) Act 2011 section 7; or
(d) the respondent consents to the order being made.
(3) Unless a greater amount is prescribed by the regulations, in subsection (2) the prescribed amount is $500 000.
(4) Nothing in this section prevents a building service complaint from being dealt with through a compulsory conference or mediation process under the State Administrative Tribunal Act 2004[.]
26 Section 36 sets out what a build remedy order may include:
(1) A building remedy order consists of one of the following
(a) an order that a person who carried out a regulated building service remedy the building service as specified in the order;
(b) an order that a person who carried out a regulated building service pay to an aggrieved person such costs of remedying the building service as the Building Commissioner or State Administrative Tribunal, as the case requires, considers reasonable and specifies in the order;
(c) an order that a person who carried out a regulated building service pay to an aggrieved person a sum of money specified in the order to compensate the aggrieved person for the failure to carry out the building service in a proper and proficient manner or for faulty or unsatisfactory building work.
(2) A building remedy order may require that the order be complied with within a time specified in the order.
(3) A person who is not a building service contractor may arrange for a building service to be carried out for the purpose of compliance by that person with a building remedy order referred to in subsection (1)(a) despite the Building Services (Registration) Act 2011 section 7[.]
27 The Tribunal has, pursuant to s 38 of the BSCRA Act power to make a building remedy order if it is satisfied that the regulated building service has not been carried out in a proper and proficient manner or is faulty or unsatisfactory.
28 The standard of 'proper and proficient' is higher standard of care than 'proper and workmanlike manner' or the reasonable care and skill of a tradesman or contractor.[2]
29 The building contract may be relevant to the proper and proficient as it 'defines what the builder was required to do, which informs the issue of workmanship'.[3]
30 The phrase 'not been carried out in a proper and proficient manner or is faulty or unsatisfactory' is a broad expression apt to cover a wide range of deficiencies in the construction of a building which can be taken into account.[4]
31 Manufacturers recommendations may be departed from if the builder otherwise acted in a proper and proficient manner. A product which is performing well, and is suitable for its application, cannot automatically be said to be faulty or unsatisfactory.[5]
32 A mere departure by a builder from its contractual obligations is insufficient to establish the work was not carried out in a proper and proficient manner or was faulty or unsatisfactory.[6]
33 Builders are not compelled to search for and install superior products over and above what is adequate for the intended purpose.[7]
34 Where the issue is not contractual, the Tribunal should be cautious in regards to ordering remedial work to be undertaken unless the applicant has demonstrated a genuine adverse effect by reason of the building work in question.[8]
35 A building service that complies with the BCA will not be found by the Tribunal to be faulty or unsatisfactory or to not to have been carried out in a proper and proficient manner except in exceptional circumstances.
36 Where there is a contractual relationship with the builder, the principles outlined in Willshee and Westcourt Ltd [2009] WASCA 87 will guide and influence the grant of any remedy which is a statutory not common law contractual remedy. But where there is no contractual relationship or other nexus with the builder, the Tribunal would generally be disinclined to grant a remedy when no faulty or unsatisfactory work is yet manifest, or likely to become manifest, particularly when there is a substantial time for any claim based on manifest faulty or unsatisfactory work to become time-barred. In all matters, the particular circumstances of the case would affect the exercise of the discretion.[9]
37 Where the complaint is one of workmanship a building remedy order may be made pursuant to s 38 of the BSCRA Act and the Tribunal is able to make orders for work to be performed or monetary compensation to be ordered.
38 The amount of compensation to be paid is that amount which would put the owner in the position they would have been had the work been performed correctly or properly together with any loss consequential upon the faulty workmanship or breach of contract.
39 The only qualification to that general principal is that the remedial work sought to be redone must be both 'necessary' and 'reasonable'. What is 'necessary' and 'reasonable' in any particular case is a question of fact.[10]
40 The test of 'unreasonableness' is only to be satisfied 'by fairly exceptional circumstances', for example where the innocent party was 'merely using a technical breach to secure an uncovenanted profit'. Its unreasonableness may be established where the cost or complexity is out of proportion to the benefit to be obtained[11].
41 The hearing was held over five days. The following experts in their respective fields gave there evidence concurrently:
Alan Walters, Master Painters & Decorators Australia
Alan Walters, Master Painters & Decorators Australia

43 Complaint item 1 was found to include the more detailed steel complaints referred to in reference points 1, 6 to 11, 15, 19, 21, 23 and 25 of the MPDA Report and was limited to the matters referred to in those paragraphs.[12] However, the parties agreed following the oral evidence at hearing of Mr Walters, the author of the MPDA Report[13] that in fact, reference point 10 in the MPDA Report referred to complaint item 4 the concrete soffits.
44 The respondent's position as set out in their closing submissions is that reference point 19 in the MPDA Report relates to complaint item 4. The applicant says it was found to be part of complaint item 1 in Owners of Island Apartments Strata Plan 52597 and Pindan Pty Ltd [2017] WASAT 25 (Pindan) and that Mr Walters' evidence was that it was part of item 1.
45 The MPDA Report essentially framed the complaint as it sets out the nature of the applicant's complaints. The MPDA Report is limited in detail.
46 The evidence of Mr Walters was to the effect that when he referred to the 'evidence of the corrosion staining to the underneath edge of the balcony section on the cement render' he did not actually know if it was corrosion as all he could see was 'red staining visible'; T:137; 31.07.17.
47 Given the evidence later given in the hearing, it became apparent that there was no evidence of any structural steel on or in the balconies other than the plastic tipped steel bar chairs the subject of complaint item 4. No evidence was given by the applicant as to what the 'red staining' on the balconies was or what rectification work was necessary to remedy the staining other than with reference to the plastic tipped steel bar chairs. The Tribunal finds reference point 19 in the MPDA Report to be part of complaint item 4 and will deal with it under that heading.
48 The parties' experts jointly 'marked up' Exhibit 5 and Exhibit 6 as to the locations of the various items referenced in the MPDA Report.
49 Mr Walters, the author of the MPDA Report, gave evidence as to his observations that were set out in his report. He conducted no testing; the statements in his report are based on his observations; T:80; 31.07.17.
50 Mr Harrison gave evidence on the first day of hearing that he tested the garage gates and found the average coating thickness of paint for all items inspected to be deficient and as such the dry film thickness was unacceptable.
51 Mr Harrison on the second day of the hearing, when asked to mark on a plan (Exhibit 6) the gates he had conducted tests on, it became apparent that the only testing he had done was in respect of gates other than the garage gates. Therefore the only evidence before the Tribunal in respect of µm (micron) testing of the garage gates is that of Dr Zarhaar as set out in his report at Exhibit 1 page 1128.
52 Dr Zarhaar gave evidence that the galvanised steel of the garage gates have been painted with a primer and topcoat system. The nature of the specified finish he said is consistent with the specification requirements (see Exhibit 1 pages 518 524). The painting system he considered would have a service life of five to seven years before needing to be recoated due to the marine environment of the Islands or less if it is not regularly maintained by freshwater washing.
53 Further, in his report, Dr Zarhaar says that the dry film thickness measurements of the paint finish taken in a sheltered internal face area produce total paint thickness readings of around 80 µm. This is equivalent to a primer coat of 15 to 20 µm and two top coats of about 30 µm each.
54 According to the Dulux specification sheet (Exhibit 3) the prima coat should have been 25 µm and the top coat 25 µm. Thus it would appear that the garage gates were painted in accordance with the specifications.
55 Leaving aside the issue of testing (which the applicant did not do on the garage gates) Mr Harrison and Mr Walters say that the evidence that the primer and top coat were not applied correctly or at all is the fact that it failed.
56 Dr Zarhaar disagrees and maintains that the painting system did not fail, that the reason it had worn away by 2013 (when first inspected by Mr Harrison and Mr Walters) was because regular maintenance was not performed on the gates such that a build-up of salt occurred which had a corrosive effect; T:120; 31.07.17.
57 The parties appear to agree that the galvanising of the garage gates was the protective coating on the gates not the painting of them; T:104 105, 109; 31.07.17.
58 No evidence was led nor was it suggested by any of the experts that the galvanising of the gates had not been properly applied or was in any way deficient.
59 Although the parties appear to agree that the painting of the gates was an aesthetic issue, the applicant maintains it was just as important that the painting of the gates last seven years as it was for the protective galvanising.
60 It was put by the applicant that AS2312 of the Building Code of Australia (BCA) should apply to the paint system. AS2312 is a 'Guide to the protection of structural steel against atmospheric corrosion by the use of protective coatings'.
61 AS 2312 could not apply to the painting system used by the applicant unless it was being used as a protective coating.
62 Dr Zarhaar was not challenged by the applicant when he gave evidence that the system as set out in the specifications whilst not in line with the AS2312, was compliant with the BCA; T:95; 31.07.17.
63 All experts agree (T:115; 31.07.17) that there was some corrosion of the steel and of the galvanising and that the gates now need to be painted. Dr Zarhaar is of the opinion that approximately 10% of the gates display a loss of paint. Mr Harrison puts it at 20%.
64 All experts agree that the actual steel corrosion is currently less than 5% of the total gate surface.
65 All agree that now the whole of the gates need repainting as they have come to the end of their 'life span' it now being some seven years since they were painted.
66 All experts agree that the gates have corroded at an accelerated rate (T:123; 31.07.17) as evidenced by the photographs taken in 2013 and Mr Harrison's and Mr Walters' evidence of what they saw when they inspected the gates in 2013.
67 Mr Walters gave evidence that the painting system was not suitable for the coastal environment (T:124; 31.07.17). He speculated that it would have started to wear away within eighteen months.
68 Stockland, by its architect provided specifications for water-based exterior paint finishes, which was the paint system used for the gates. This specification called for one coat of professional ultra-base galvanised prime and two coats of Dulux X10 acrylic gloss or low sheen at Exhibit 1 page 53.
69 Mr Walters in the MPDA Report - particular 7, refers to a steel lintel above the garage gates. The evidence at hearing disclosed that it was not in fact a steel lintel but rather a 'horizontal rectangular hollow section' and that it is metal work not structural steel; T:26; 01.08.17.
70 Dr Zarhaar and Mr Walters confirmed that their evidence in respect of the garage gates applied equally to the lintel and that Dr Zarhaar had taken the 'lintel' to be part of the gate when discussing the condition and cause of the deterioration of the condition of the gates; T:28; 01.08.17.
71 He also confirmed that his evidence was in respect of both gates and that they are both of the same design, same structure and same materials however, one is more whether exposed to weather and is in a more severe state than the other but other than that they are the same; T:29; 01.08.17.
Complaint item 1 - pergolas and walkways, structural steel elements to the western elevation to blocks 1 and 2
72 The respondent accepts liability for the structural steel remedial work with respect to the pergolas. It does not agree that the walkways should be included.
73 In these proceedings, the respondent submits that the 'walkways' are not part of the complaint referred to the Tribunal by the Building Commission. It is a submission the Tribunal has difficulty understanding.
74 'Veranda awnings and walkways' are the steel complaints listed in the original Complaint Schedule. In Pindan the issue was what additional items were included in this item. The respondent accepted at [82] that 'veranda awnings and walkways' were included that it is those items set out in the Complaint Schedule. The respondent did not take issue with the reference in the complaint being to 'veranda awnings' and accepts this is a reference to the 'pergolas', as they are otherwise described including on the plans Exhibit 5 and Exhibit 6.
75 The respondent at the hearing maintained that in the event the Tribunal finds that walkways are part of the complaint it does not accept liability for any necessary remedial work.
76 The applicant's experts were unable to provide any useful evidence in respect of any testing that was carried out. Dr Zarhaar gave evidence that there was an inadequate film of paint on the walkways and that their condition is the same as that of the pergolas; T:65; 01.08.17.
77 The reference to structural steel elements to the western elevation to blocks 1 and 2 being reference points 11 and 15 (Exhibit 1 page 368), 'showing signs of premature corrosion to various areas horizontal and vertical beams' is not a reference to a part of or connected with the pergolas but it is work the respondent has agreed to remedy; T:33; 01.08.17.
78 It is not clear what particular 19 of the matters included in complaint item 1 is. Mr Walters in his evidence accepted that he didn't know in fact if what he had observed as corrosion staining on the concrete balconies was rust. All he could say was that it was red in colour and that he made the assumption that it was corrosion; T:137; 31.07.17.
Complaint item 1 - gates and fences (other than basement gates)
79 Other items included in complaint item 1 are the gates and fences. As with most complaint items different terminology is used by different experts and the parties to describe the same thing.
80 Evidence was given and not challenged that the reference in the MPDA Report particular 1 'Front perimeter (East Elevation) Powder Coated steel posts to unit 23' is in fact a reference to posts supporting the gate to unit 23. It is not marked on the plan of the property (Exhibit 5) as having been inspected by the various experts other than by Mr Walters.
81 The evidence in respect of this particular is that the post supporting the gate (and others) is failing, evidenced by the paint peeling off the bottom of the posts and rusting of the steel.
82 Evidence was given and not challenged that the 'balustrades' are a reference to the horizontal rails of the fence. There are mid-height horizontal beams, one at the top and one at the bottom. The uprights are also referred to as the upright posts in the fence. The Tribunal will therefore refer to these as 'posts' and the horizontal rails as 'balustrades'. The balustrades and the other central horizontal members of the fence are powder coated steel.
83 It was suggested by the Tribunal to the experts that all the posts and indeed the fences should have, according to the specifications been galvanized but in fact have not been.
84 The experts agreed that those parts of the fences other than the feet of the posts not galvanized have not failed and that the fact that the posts are not galvanized has not made a difference to their durability; T:38; 01.08.17.
85 The 'bollards' referred to by Mr Harrison are not a reference to the balustrades of the fence but the steel supports to the pedestrian gates.
86 The results of the testing Mr Harrison did of those areas are not disputed. His results that there was insufficient paint or film on the 'bollards' is premised on the belief that Dulux Duramate GPE should have total build of 300 µm and the average coating of the areas tested showed a build of 128 µm. However, as the Dulux Duramate GPE is not the paint system used his evidence is of little assistance to the Tribunal.
87 Mr Walters observed that there was evidence of delamination and corrosion on the feet or base plates of the posts but could not assist further.
88 Dr Zarhaar agreed that the delamination and corrosion of the base plates of the steel posts could be caused by a fracturing of the powder coating. He further agreed with the speculation that this could have been caused by the tightening of the bolts when the posts were installed; T:40 41; 01.08.17.
89 All experts agreed that a build of salts from the marine environment in which they are situated would have a corrosive effect if left to sit or pool on the base plates and not regularly washed off.
90 No evidence was led by the applicant to which and how many base plates were now delaminating.
91 The applicant's complaint in respect of the acrylic texture is confined to the lack of an acrylic shield coating to the areas that received the AcraTex Coventry Coarse finish on the walls. It was agreed that all but for a very small area the concrete walls received an AcraTex Coventry Coarse finish coating and the rendered masonry walls received AcraShield.
92 Mr Walters gave evidence that the difference between application of the AcraShield and AcraTex Coventry Coarse finish is the intermediate coat. The AcraTex Coventry Coarse finish is applied to cement render to give it a sand finish look. Because the products are different, the only way you can achieve a consistency of colour between the AcraShield areas and those that received the AcraTex Coventry Coarse finish is by applying a top coat of AcraShield to the AcraTex Coventry Coarse finish; T:147; 02.08.17.
93 Further, without a top coat of AcraShield, the areas with AcraTex Coventry Coarse finish will pick up more dirt, having a negative aesthetic look and would require more maintenance to keep them clean.
94 Those surfaces with a top coat of AcraShield would be able to be cleaned down by rain. With a coated surface you would need to wash them down for 12 to 18 months but without the top coat of AcraShield significantly more regularly.
95 The difference in colour of the two different surface types that is between the AcraTex Coventry Coarse finish and the AcraShield without a top coat of AcraShield would get worse over time; T:171; 02.08.17.
96 When Mr Walters inspected the buildings in 2013 he said there was a dramatic difference in the colour between the difference surface finishes.
97 The build-up of surface contaminates would ultimately have a detrimental effect on the performance of the render as a build-up of salts would have a hydroscopic effect; T:167; 02.08.17.
98 In essence, the experts agreed that without the top coat of AcraShield the Coventry Coarse finish would not last as long and would need recoating sooner. However the evidence was also that it had lasted seven years, the required period for the warranty.
99 Mr Walters was of the opinion that to now recoat the surface you would need to clean it with a solvent or brush it down with a soft brush before applying the top coat.
100 As a coating the AcraTex Coventry Coarse finish has not functionally failed, it has not failing as a coating; T:171; 02.08.17.
101 The experts agreed that with a top coat of AcraShield the applicant would have been entitled to receive a ten year warranty from Dulux or it would have lasted ten years and, without a top coat, it would not have been entitled to a warranty of only seven years; T:182; 02.08.17.
102 The experts agreed that at the present time, two top coats of AcraShield are required. However, Mr Walters maintained that had a top coat of AcraShield been applied originally you would now only to apply one top coat of AcraShield; T:197; 02.08.17.
103 All experts agree that had the top coat of AcraShield been applied at the time, the time for a recoat would be in three years' time, not now; T:198; 02.08.17.
104 Mr Walters submitted that Dulux would always have recommended a top coat of AcraShield but did not require it; T:200; 02.08.17.
105 Mr Martelli, the respondent's expert, accepted that the manufacturer Dulux always recommended AcraShield as a top coat. He would recommend Acrashield as a top coat when using a AcraTex Coventry Coarse finish coating system.
106 Dr Zarhaar accepted that best practice requires the application of an AcraShield top coat to the underlying texture coat; T:205; 02.08.17.
108 Evidence in respect of complaint item 3 began by the Tribunal once again having to seek clarification as to the areas of the buildings said to be the subject of the complaint.
109 The applicant agreed that the complaint and the remedial work sought was in respect of the upper levels of the two buildings; T:8 11, 15; 02.08.17.
110 Mr Walters did not conduct testing and his report is based on his observations.
111 He observed that the timber had 'failed' all around the building, on the edges of the board but was worse on the western elevation which is the ocean side.
112 Mr Walters speculated as to the product used and though it did not look as if Intergrain Ultra Clear had been applied to the external timber as claimed by the respondent. He did agree that had Intergrain Ultra Clear been used it would have been a suitable product and would require recoating every two to four years depending upon the environmental conditions.
113 Mr Walters expressed the view that the number of coats of Intergrain Ultra Clear required would depend upon the length of time you wished it to last. The greater the build-up, the longer it would last. A rule of thumb was that the first coat was for the timber and every subsequent coat was for every year you wished it to last - so four coats would last three years.
114 Mr Walters' view was that each coat of Intergrain Ultra Clear would produce a covering of about 35 µm per coat. Mr Nairn suggested to Mr Walters that the Dulux website recommended four or more coats of Intergrain Ultra Clear in an extreme marine environment such as at the Islands. Dr Zarhaar did not demur from this suggestion as being correct.
115 Mr Walters said that where maintenance was due after two years he would not expect the boards to be delaminating to the extent they were, or at all, as observed by him at the Islands. (He saw them after three years). He said he would expect the coating to be still intact. He opined that what had happened with the soffits on the Islands is that moisture had got into the edges and caused them to peel.
116 He agreed that regular household maintenance would be desirable. That is, a washing down of the panels to prevent salt build-up which, as we heard previously, has a corrosive effect. However, it is apparent that it would be extremely difficult if not impossible to perform any maintenance on most of the soffits without significant infrastructure such as a 135 boom lift (T:22; 02.08.17) and was not something that could be done other than by trained or experienced people.
117 Mr Harris did conduct testing on a sheet of exterior plywood and provided a diagram in his report that showed where it came from. He provided samples to a third party testing house which were inconclusive.
118 Dr Zarhaar examined sheets of the exterior plywood soffit taken from the western elevation and north eastern elevation. Dr Zarhaar, who conducted his investigations in 2016, said the building was then seven years old and that there was no way he could at that time extrapolate back to whether two, three or four coats of Intergrain Ultra Clear had been applied because at that stage the product had actually attritioned itself away to nothing.
119 He confirmed the photos showed the delamination was migrating from the leading weather edge and that the coating is weathering away; T:37; 02.08.17.
120 In Dr Zarhaar's report (Exhibit 1 page 1327) he says that the thickness for each coat of Intergrain Ultra Clear would be about 10 µm. At the hearing he agreed with Mr Walters that it should be about 35 µm per coat; T:39; 02.08.17.
121 On testing, Dr Zarhaar found the micron thickness to be 10 µm on the less exposed board from the sheltered side and that it was unlikely that if it was now 10 µm it was ever 120 µm or more; T:40; 02.08.17.
122 Mr Perrion gave evidence that when he purchased his unit some six months after it was completed, he noted that there was blackening around the edges of the soffit which he identified as water damage.
123 Dr Zarhaar agreed that plywood only goes black if moisture is able to get into the plywood itself and that if it had shown areas of black on the leading edge or express edge it would indicate that perhaps those edges were not sealed as well as they should have been; T:45; 02.08.17.
124 It was agreed by the parties that the specification for the Islands required marine plywood to be used for the soffits. Dr Zarhaar said the use of plywood instead of marine plywood would not have made a difference to the durability of the plywood. This was not challenged by either Mr Harris or Mr Walters.
125 Dr Zarhaar also was of the opinion that even if the soffits had received four coats of Intergrain Ultra Clear varnish (as was required in the specifications) they would have needed resealing after two years in that environment but you would not have expected to see the damage as described by Mr Perrion after six to twelve months or even after two years; T:56; 02.08.17.
126 The specifications required the soffits to be 'presealed and machine applied'. Mr Harrison was of the view that this meant that the product had to be dipped in a tank of varnish at a factory. Neither Dr Zarhaar or Mr Walters agreed with Mr Harrison and they were both of the view that it meant presealed before installation with a spray gun as opposed to painted with a brush or roller; T:8788; 02.08.17.
127 It was agreed by the experts that whether it would be possible to reseal and carry out remedial work on the soffits without removing the panels would depend upon whether the joints of the panels were expressed joints or butted joints. It was agreed that if they were expressed joints the sheets would not need to be removed but if they were butted then the sheets would need to be removed; T:60; 02.08.17.
128 It was also agreed by the experts that even if the soffits had been correctly and properly installed, had been coated with the appropriate type and coats of sealant or varnish, after seven years they would need to be resealed.
129 The experts also agreed they were unaware of any plywood product regardless of what sealant was used that would last seven years in the Islands marine environment.
130 Mr Walters, an expert in painting and painting systems, and Dr Zarhaar, an expert chemist, gave evidence that the type of exterior timber soffits chosen by the architect or Stockland could never have lasted more than two years before needing recoating and not seven years before the first maintenance, as required by the specifications.
131 Dr Zarhaar's evidence was that when he tested the panels of the exterior soffits that were on the sheltered side of the building the film thickness after seven years was only at a maximum 10 µm. Further, in his expert opinion if the required coatings of sealant had been applied, the soffits would originally have had a covering of between 120 and 150 µm and over seven years this could not have degraded to the point where there was only a film build-up of 10 µm.
132 Dr Airey's qualifications in the building industry (as set out in her Curriculum Vitae) are as a material focused scientist with a doctorate in chemistry who specialises in the investigations into reinforcement corrosion in identifying mechanisms of deterioration of built environment materials and specifying preventive/remedial solutions; and chemically focused environmental projects.
133 Mr Airey (as set out in his Curriculum Vitae) is a senior practising civil and structural engineer, his lengthy experience is in the area of concrete design and construction and all aspects of remediation and lectures all over Australia in this field.
134 Dr Zarhaar also gave evidence as an expert in respect of this item and (as set out in his Curriculum Vitae) has extensive technical knowledge of materials chemistry, has been engaged as a specialist consultant involving both design/specification issues and technical defect/failure investigations of coatings and materials and has been accepted as an expert in matters of coatings, timber and building materials and workmanship in cases before the Building Disputes Tribunal and Australian courts of law.
135 Following clarification with Mr Airey and Dr Airey, it was their evidence that based on the relevant BCA standard at the time the Islands were built:
136 Mr Airey also said that Perth is one of the windiest cities in the world with very strong prevailing winds.
137 Dr Zarhaar agreed the site was greater than B1, namely B2, but did not agree that on the exposed side it was classified as C. The build structural engineers had classified the whole of the site as B2.
138 The building licence issued for the Islands was for a B2 site and in accordance with the BCA required the installation of plastic bar chairs in external steel reinforcing. It was conceded by the respondent that plastic tipped steel bar chairs had been used on the external soffits.
139 Plastic bar chairs were required by the building licence to be used in the external concrete soffits.
140 All the experts agreed that according to the building licence, the consulting engineers of the Islands and best practice, plastic bar chairs should have been used on the external soffits of the building, not plastic tipped steel bar chairs. They also all agree that the rust spots that have appeared on the concrete soffits are from metal tips that are too close to the surface of the concrete; T:26 27; 03.08.17.
141 Dr Airey and Mr Airey referred to empirical data that states that a site classified as a B2 marine environment requires a minimum cover of 45 millimetres of concrete to give reasonable durability to steel reinforcement and 70 millimetres for a C classified site.
142 As the structural engineers' plans call for only 40 millimetres of concrete, the Tribunal assumes that that was the depth of the concrete poured. However, no evidence was led that suggested that it was the incorrect cover of concrete for a B2 site that led to the premature rusting of the plastic tipped steel bar chairs that in turn had caused the rust spots on the concrete soffits.
143 It was explained to the Tribunal that the tips of the bar chairs are not designed to be covered by any depth of concrete. The bar chairs sit on the form work and hold up the reinforcing steel and the concrete is poured to the depth of the bar chair this distance between the tip of the bar chair and the reinforced steel is referred to as the 'cover zone'. The depth of the concrete is designed to be the thickness necessary to provide protection to the reinforced steel from the B2 environment. No concrete is poured under the bar chair such that if there is any covering of concrete over the tips of the bar chairs, it is very small.
144 The significance of the cover zone is described by Dr Airey as:
...
Well, it means that there's some potentially corrodible material in the cover zone. The bar chairs the purpose of the bar chairs is to establish the cover height so that the reinforcement can be the right cover can be achieved during the pour, and after the concrete is poured, the legs of the bar chairs are, by their nature, sort of penetrating down to the soffit. And the cover to those bar chairs is effectively zero if there's any exposed metal or plastic part of the plastictipped if that's used, and once they're once there's various (indistinct) of corrosion.
Carbonation has been talked about. That's when where carbon dioxide permeates through coatings and the concrete, and causes some local acidification. Now, that can cause the corrosion to start occurring. And the other mechanism is the chloride from sea salt which is a catalyst to corrosion. Concrete, by its nature, has quite a good reservoir against corrosion, but because these chair tips are on the very surface, the body of the concrete is just not there to really be too effective, so those tips will start corroding[.]
(T:32 33; 03.08.17)
145 The issue of the effect of having plastic tipped steel bar chairs as opposed to all plastic bar chairs was described by Dr Airey:
...
The immediate risk is if a puncture occurs, but you're quite right, in the steel above the line of the plastic cap will potentially corrode, and that is in the cover zone, between in front of or closer to the soffit than the reinforcement.
...
There's a couple of considerations. One which you pointed out, yourself, which is the plastic tip has a discrete depth. But beyond that, if there's contaminants, carbonation or chloride attack affecting the concrete as it ages, that part of the bar chair will start corroding. So, for example, you may have something which has an intact plastic tip, but in due Coarse, say, after 20 years, when the carbonation crunch might be at that point, or the chloride level reaches a certain level, you may get more widespread corrosion happening with all those bar chairs. Now, the other issue...
...
... And for those ones which have punctured and have the some area at the bottom exposed, I think that they would corrode based on the environmental effects, the certain effects, such as the distance provided by the AcraTex cover. Now, the AcraTex render is a rough a roughfinish surface and then it's been painted over the top with some good quality paint. But the AcraTex being undulating, that in itself causes a different amount of protection in different areas of the soffit.
But the the main thing, I think, which would affect when those things start corroding or not is (a) weather that puncture has occurred; (b) how much chloride has been deposited. The chloride deposition can be quite local (indistinct) chloride tends to come and stick onto surfaces and that can have Peter may may actually talk to this a little bit better than myself, but you tend to have some quite localised effects on buildings with chloride sort of dumping and accumulating in certain soffit areas, whereas other soffit areas which may be better cleaned off by wind or rain, they they may have less chloride accumulation.
All the soffits will be affected by carbonation. Carbonation is the atmospheric the atmosphere has carbon dioxide in it, and that is roughly constant. However, there's a lot of localised variation of carbonation as well, depending on its exposure zone. In still areas you tend to get more carbonation. So the carbon dioxide in nonwindy areas will have an opportunity to sit and react with the concrete, whereas in windswept areas it will tend to get blown blow off the off the face of the building. So carbonation is an odd one, because the highest rate of carbonation is actually in indoor concrete, and the lowest rate is in highly exposed areas[.]
(T:3738; 03.08.17)
146 It was accepted by the respondent's expert Dr Zarhaar that a rust spot on the concrete soffit meant there was rusting of the bar chair and that the rust spot needed to be remedied.
147 The reason any rust on the bar chair needs to be dealt with is because of the negative effect the corroding of the plastic tipped steel bar chairs has on the reinforcing steel.
148 The plastic tipped steel bar chairs are in contact with the reinforcing steel and as the plastic tipped steel bar chairs corrode and oxidise they will try to passivate them by drawing current, that is pulling electrons from the reinforcing steel thus weakening it; T:42; 03.08.17.
149 Dr Zarhaar maintained that if no further rust spots had shown through over the past seven years and where the rust spots had been repaired and no new rust appeared it meant that the remaining plastic tipped steel bar chairs had not started to rust.
150 It is Dr Zarhaar's position that a corroding bar chair inside the concrete is not a problem. It is his position that where a tip of a bar chair has corroded it does not mean the bar chair that is encapsulated in the concrete is corroding; T:49; 03.08.17.
151 The experts all agree the design life of concrete structures is forty to sixty years (BCA AS3600). The plastic tipped steel bar chairs will eventually corrode because they are metal not plastic and they will shorten the life of the building.
152 The building licence requires various provisions to ensure that especially durable concrete was used in the balcony concrete soffits and front edges, including:
153 The height of the bar chair is the depth of the cover zone of the reinforcing steel. The greater the cover zone, the greater the protection the reinforcing steel has from the effects of atmospheric corrosion. The experts agree that the effect of having a metal bar chair in the cover zone that will inevitably corrode, reduces the life of the steel reinforcing.
154 Dr Zarhaar takes the view that the reduction in the life span of the building is not of such a significance that it warrants anything more than treatment of the plastic tipped steel bar chairs that have exhibited rusting by rust spots appearing on the concrete soffits.
155 It is Dr Zarhaar's view that while the plastic tipped steel bar chairs will eventually rust or corrode and affect the structural integrity of the structural steel, the effect will be minimal and not affect the design life of the building. Part of his reasoning for this includes the fact that the applicant would reasonably be required to perform regular maintenance of recoating the concrete soffits every seven to 10 years; T:5; 03.08.17.
156 Dr Zarhaar also expressed the view that given there has been no further reported signs of rusting on the concrete soffits it meant that the remaining plastic tipped steel bar chairs had not commenced to rust; T:41; 03.08.17.
157 Dr Airey was quite clear in her evidence (T:41; 03.08.17) that the absence of a rust stain and consequently evidence of plastic tipped steel bar chairs rusting in the last seven years does not mean that rusting of other plastic tipped steel bar chairs will not occur at some time in the not too distant future.
158 Evidence was led that when a timber soffits was removed, rust spots were found that has not yet been treated; T:134; 03.08.17. It was only when the timber was removed from the soffit that the rusting bar chair was noticed. There is no evidence of when the rust first became visible on the concrete because it was covered by the timber soffit.
159 Dr Zarhaar confirmed that there needs to be a cover of concrete to protect the end of the bar chair and that it has to be adequate; T:162; 03.08.17.
160 Dr Zarhaar also admitted that the plastic tipped steel bar chairs that are in the cover zone haven't got the required 45 millimetres of concrete protecting them against the B2 environment and they are going to corrode, '[a]nd in this case, it's going to corrode inside that cover zone over a period of time. Where it hasn't even got a paint finish to keep the salts away, it's going to turn into a rust spot on the on the soffit'; T:63; 03.08.17.
161 Dr Zarhaar does not dispute that it is a requirement of the Building Code not to have metal within the cover zone.
162 What the effect of having plastic tipped steel bar chairs instead of plastic bar chairs means is that the cover zone is reduced to the seize of the plastic tip, that is, presuming that the plastic tip is still intact and is not deteriorating or otherwise exposed to the atmospheric effects of the B2 marine environment.
163 Dr Zarhaar argues that this doesn't matter because although he accepts that the reinforced steel will deteriorate and corrode sooner than if the plastic steel bar chairs were not there, he does not agree that it will result in a reduced service life of the concrete; T:57; 03.08.17.
164 Dr Airey's evidence is also that the rusting of the plastic tipped steel bar chairs isn't restricted to the direct electrochemical effect of the plastic tipped steel bar chairs on the reinforced steel but will have a generalised effect on the concrete around it and the reinforced steel.
165 Dr Airey stated that the Islands are now at the stage of first maintenance in accordance with international standards. She explained this to mean the conditions of the concrete are such that they support corrosion. There is an introductory period of an accumulation of gas and salts etc. in the concrete and it is these conditions in the concrete that predisposes it to corrosion. Further, that the onset of the corrosion of the plastic tipped steel bar chairs is proof that the stage of first maintenance has been reached; T:162; 03.08.17.
166 The evidence from the experts differed somewhat as to the method to be used in remedying those areas of the soffits that have shown signs of corrosion. All agreed that any rust or corrosion present on a bar chair must be removed. Dr Airey and Mr Airey proposed and Dr Zarhaar accepted that the corroded plastic tipped steel bar chairs needed to be cut back to 30 millimetres; T:146; 03.08.17.
167 Dr Airey and Mr Airey considered you needed to actually measure how far you cut in to the bar chair. Dr Zarhaar was of the view that you had to go far enough to ensure you had removed all the rust/corrosion and that to go to 30 millimetres would give a greater degree of confidence of that; T:147; 03.08.17. It was agreed by all experts that it is essential that the steel must be clean.
170 It was agreed by the experts that it was not necessary to use the Galmet Ionize Sealer or the Dulux Weather Max HBR but it would not have a detrimental effect if you did use it.
171 The Dulux Luxepoxy coating was also agreed by the experts as not being the correct type of epoxy to use as it is not a zinc rich epoxy which they agreed was required.
172 Another issue of the repair was the area around the bar chair to be removed. Dr Airey and Mr Airey are of the opinion that a square area should be saw cut around the rusting bar chair of approximately 30 millimetres to 40 millimetres to remove any contaminated concrete; T:503; 03.08.17; Exhibit 1. At the hearing, Dr Airey agreed that it could be saw cut or drilled out which Dr Zarhaar considered more cost effective.
173 Specialist concrete repair contractors were not used for the repairs. The repairs were supervised by Mr Terace, an employee of the respondent, who gave evidence at hearing. His evidence was that he was informed by Dr Zarhaar as to the method of repair to be used but no written instructions or scope of works was prepared. His instructions to the employees undertaking the task were also oral.
174 His evidence was that following discussions with his workers he decided upon the additional steps that were not in accordance with Dr Zarhaar's system. He took no advice on the use of the additional steps and thought it was a better system than that suggested by Dr Zarhaar as it meant additional protective coatings were used.
175 Mr Terace did not oversee all of the repairs but was 'on site on a weekly basis' (T:160; 04.08.17) and checked on what the employees were doing. There is no formal list of where the repairs were performed and the diagram shown to the Tribunal as to where the repairs were carried out was put together from the memory of the workers and from their diaries.
176 This complaint item relates to leaks in three different areas: apartment 17, two storerooms and the cost of remedial work in an external leak near the swimming pool in building No 23.
177 The evidence from Mr Machall was that he saw no leaks in apartment 17, Mr Perrion's apartment, because it was not raining. He observed that the skirting board in the lower level of apartment 17 was swollen and showed evidence of previous water ingress but from where or how the water had entered he was unable to do more than guess. Mr Machall speculated that it may have come from a low level balcony or through the side around the window junction with the wall; T:120; 02.08.17.
178 Mr Machall was not able to form an opinion as to the cause of the ingress of the water that caused the swelling of the skirting board; T:119; 02.08.17.
179 Mr Perrin also gave evidence of a 'water feature' coming from the pelmet in front of the glass window. He said water 'leaked' down on to the pelmet and then pooled on the marble floor.
180 Mr Machall also gave evidence that he found a post or veranda post where the water proof membrane appeared to not continue up the post as it should.
181 Mr Machall observed the reported leaks in store 2 of the parking area through the grill and could see staining on the far wall but could not say if it was due to a leak that had been repaired or whether the effervescence was due to ongoing water ingress.
182 In respect of unit 1, Mr Machall was able to gain access but could not say if the effervescence on the wall was due to a leak that had been repaired or whether the effervescence was due to ongoing water ingress.
183 There was a leak in connection with one of the swimming pools for which the respondent accepts liability but disputes the cost of the remedial work claimed.
184 The applicant alleges it had no choice but to arrange to have the leak fixed as the respondent had refused to do so.
185 The respondent produced emails which showed that whilst it had originally refused to accept liability for the leak at the lap pool it did eventually do so.
186 The respondent says it should only be liable for the cost of remedial work that it would have incurred had it been given the opportunity to repair the leak.
187 It is not disputed that the specifications originally called for jarrah decking around all the swimming pools but Pelawan was in fact installed, and that Stockland agreed to the substitution of Pelawn.
188 The applicant did not submit that the installation of Pelawan (the regulated building service) instead of Jarrah meant the respondent did not carry out the work in a proper and proficient manner.
189 Mr Kalie, who is an expert in timber, is an industry accredited flooring inspector and the founding director of the Australian Timber Floor Association (ATFA) the industry body, gave evidence on behalf of the applicant that Pelawan was a suitable timber to use in place of Jarrah provided it meet the appropriate criteria. Specifically, it needed to meet the equilibrium moisture content (EMC) which is the value that a timber will correspond with ambient temperatures and conditions and other influences from other hydroscopic materials, to where it is in a comfort zone.
190 Mr Kalie explained what the EMC was and how it was calculated and said that in Western Australia it was recommended that timber have an EMC of between 10 and 15. The specifications required the timber conform to the AS1080 which is BCA standard for the moisture content in timber.
191 Mr Kalie inspected the decking on 1 March 2016. He gave evidence in accordance with his report (Exhibit 1 page 640) and expressed the view that when he viewed the decking he considered it all needed to be replaced even though some areas were in a worst state than others.
192 The areas that were under cover he accepted could have been salvaged but would have needed to be fully removed and relaid because the shrinkage had caused wide gaps between the boards that were not safe and it would not have been economic to remove and relay the decking.
193 It is Mr Kalie's expert opinion that the shrinkage of the boards and the failure of the decking was due to the moisture content values of the boards at installation significantly exceeding those recommended.
194 Mr Kalie believed the drying out of the boards once laid has resulted in excessive shrinkage degrading the installation integrity and appearance of the decking to the point that the installation areas are considered unacceptable.
195 Dr Zarhaar in his written report suggested that the way he boards had been cut may have had a significant effect on cupping and shrinkage.
196 Dr Zarhaar agreed with Mr Kalie that there had been significant shrinkage of the boards of the decking. He agreed also that in the outside exposed areas the distortion in the boards was quite severe and above what one would expect in the environment over time. He agreed it was excessive, had detracted from the finish and the movement in the boards was unacceptable.
197 Mr Kalie gave evidence that the gap between the boards that were not cupped or distorted exceeded 17 millimetres. Mr Kalie said that the ATFA standard was 3 to 5 millimetre gaps.
198 Dr Zarhaar believed there was no Australian standard for gaps and considered from a compliance point of view it was acceptable but agreed from a desirable point of view it was not acceptable and may be an issue from a user safety point of view.
199 Dr Zarhaar on further consideration, accepted that all the timber in the outside exposed areas need to be replaced; T:124; 03.08.17.
200 Dr Zarhaar agreed that the dilapidated condition of the boards was not a function of a lack of maintenance; T:113; 03.08.17.
201 It was accepted by the experts that the decking had not performed the way it should. The technical data referred to and the physical evidence of serious distortion and significant shrinkage noted across the decking indicated that the degree of movement experienced over time exceeded that which is acceptable.
202 Dr Zarhaar considered that in both buildings, two thirds of the boards needed replacing. He also agreed that it may be more economical to replace those boards not distorted but needing to be re-laid because of the excessive gap between them; T:125; 03.08.17.
203 Mr Wade, in his evidence, alleged he had provided quotes for the variations to the original quoted work but did not provide any copies to the Tribunal.
204 The original quote and the subsequent invoices for the work performed by Mr Wade alleged the area of the decking he had performed work on was 420m².
205 Mr Murphy, an employee of the respondent, gave evidence that he measured the pool decking area in question and that it was about 270m² 276m². His measurement was based on the plans. It was not suggested by the applicant that the decking was not constructed in accordance with the plans. Additionally his measurement is consistent with the amount of timber that was originally ordered by the respondent.
206 Mr Wade was unable to provide a breakdown of his charges or any details of his invoices for the Tribunal.
207 Mr Wade said that the quantity of timber he alleged he replaced was based on him measuring the site; T:78; 04.08.17. Both Mr Wade and Mr Murphy made allowance in their calculation for wastage.
208 It was put by the applicant that the quotes provide by the respondent may possibly reflect a better price than the applicant could have obtained.
209 The costings put forward by the respondent are based on quotations it received for 272.5m² of decking.
210 Neither Mr Wade's original quote or the one from Timber Floor Perfection Pty Ltd (TFP) are itemised.
211 The subframe to the decking was also replaced by the applicant. The applicant said the reason it was replaced, was because parts of it were found to be rotten when the decking was removed.
212 The respondent denies there was any problem with the sub-frame. The respondent alleges that the applicant's motivation for replacing the subframe was because a different type of or differently spaced sub-frame was necessary to support the new replacement composite decking.
213 Mr Wade gave evidence that the original quote he provided to the applicant was on the basis he could use the existing sub-frame. He said that when he removed the decking he found the subframe to be rotten in parts. Mr Wade said that where the decking was undercover it was not too bad but when he lifted the decking on the western side he found it was rotten.
214 Mr Wade gave evidence that upon discovering the problem he contacted the project supervisor Mr J Norrich and a meeting was arranged to discuss the problem. This is inconsistent with the reports of the project manager to the applicant who make no note of any meeting or any difficulty with the rotting of the subframe. The report dated 4 May 2016 informed the applicant that Mr Wade had started to remove the decking and expected to have completed the removal by the end of the week. The report dated 6 May 2016 stated that all the existing hardwood had been removed and had revealed various problems but relevantly not any rotting of the sub-frame. The report dated 11 May 2016 stated that the decking was progressing with no problems reported. The report dated 25 May 2016 stated that the decking had been completed and the decking contractors had left the site.
215 The parties have reached a settlement in respect of complaint item 22 and accordingly an order in respect of this complaint item is not sought by the applicant.
216 The Tribunal does not have evidence that the paint coating was not applied to the garage gates properly. The applicant's experts speculate that this was the cause of the paint degradation and corrosion of the galvanizing and steel. No testing was carried out by the applicant's expert on the gates to be able to substantiate this as a probable rather than possible cause.
217 All experts agree that a build-up of salts would cause corrosion. The respondent's expert, Mr Zarhaar, gave evidence of conversations he had had with persons living in the Islands who said no maintenance had been carried out on the garage gates. Whilst the Tribunal is not required to follow the rules of evidence the Tribunal is unable to place much reliance, if any upon hearsay evidence of this nature.
218 Two members of the Strata Company gave evidence at the hearing but neither they nor anyone else on behalf of the applicant gave evidence of any regular maintenance work in the form of washing down the garage gates being performed on a regular basis. The applicant was aware that the maintenance of the gates was a live issue.
219 The Tribunal finds that it is more likely than not that the garage gates were not washed down with fresh water on a regular basis.
220 The applicant says it was a design and construct contract and therefore the respondent as builder had a responsibility to use a product fit for purpose.
221 Whilst it was not challenged by the respondent that it was a design and construct project, the contract with the developer, Stockland, required the respondent to follow very detailed specifications.
222 The contract with Stockland included that the respondent build to the specifications provided by Stockland. The respondent did not have a free hand to choose how to build the Islands.
223 The specifications called for the paint system the respondent used, namely professional ultra-base galvanised prime and two coats of Dulux X10. The respondent was required to build to the specifications.
224 The applicant's experts did not challenge Dr Zarhaar's opinion that the system complied with the BCA.
225 The Tribunal has no reason not to accept that Mr Walters, an expert paint consultant, is correct and the painting system used by the respondent was not fit for purpose; however there is no evidence that the builder knew or should have known that it was not fit for purpose.
226 The Tribunal is not satisfied that the corrosion and/or wearing away prematurely or otherwise of the paint on the garage gates was caused by the paint coating system being improperly or incorrectly applied, that is that the regulated building service was not carried out a proper and proficient manner or was faulty or unsatisfactory. The Tribunal declines to make a building remedy order.
227 Dr Zarhaar and Mr Walters confirmed that their evidence in respect of the garage gates applied equally to the lintel and that Dr Zarhaar had taken the 'lintel' to be part of the gate when discussing the condition and cause of the deterioration of the condition of the gates; T:28; 01.08.17.
228 He also confirmed that his evidence was in respect of both gates and that they are both of the same design, same structure and same materials however one is more whether exposed to weather and is in a more severe state than the other but other than that, they are the same; T:29; 01.08.17.
229 For the reasons set out above, the Tribunal is not satisfied that the corrosion and/or wearing away prematurely or otherwise of the paint on the garage gates lintel was caused by a regulated building service not being carried out in a proper and proficient manner or was faulty or unsatisfactory and declines to make a building remedy order.
230 'Veranda awnings and walkways' are the steel complaints listed in the original Complaint Schedule. The respondent accepted in Pindan at [82] that 'veranda awnings and walkways' were included in the complaint. The respondent did not take issue with the reference in the complaint being to 'veranda awnings' and accepts this is a reference to the 'pergolas', as they are otherwise described including on the plans (Exhibit 5 and Exhibit 6).
231 The Tribunal finds that the walkways are included in the complaint item in respect of the structural steel.
232 Dr Zarhaar, the respondent's expert, gave evidence that there was an inadequate film of paint on the walkways and that their condition is the same as that of the pergolas; T:65; 01:08:17. Dr Zarhaar went on to comment that had the paint to the pergolas and walkways been applied in accordance with the specifications 'we wouldn't be in this situation now'; T:66; 01.08.17.
233 The specifications inform the Tribunal as to the required standard of workmanship.
234 The Tribunal finds the walkways have not performed as they should due to an insufficient film build up on the walkways evident by premature surface corrosion.
235 The Tribunal is satisfied and finds that the regulated building service in respect of the pergolas, walkways, structural steel elements to the western elevation to the Islands and the western elevation of Block 1 has not been carried out in a proper and proficient manner or is faulty or unsatisfactory. The remedial work should be as described by Dr Zarhaar at T:65; 01.08.17.
236 It is not clear what particular 19 of the matters included in complaint item 1 is. Mr Walters, in his evidence, accepted that he did not know in fact if what he had observed as corrosion staining on the concrete balconies was rust. All he could say was that it was red in colour and that he made the assumption that it was corrosion; T:137; 31.07.17.
237 In so far as any rust appearing on balconies is not part of complaint item 4, the Tribunal is not persuaded that the red staining is caused a result of the regulated building service not being carried out in a proper and proficient manner or being faulty or unsatisfactory and declines to make a building remedy or in respect of the item.
Complaint item 1 - gates and fences (other than basement gates)
238 The bollards referred to by Mr Harrison are in fact the steel supports to the pedestrian gates. On the basis of Pindan as the supports are integral to the gates they are included in the complaint.
239 The Tribunal finds that the bollards are part of the complaint referred to the Tribunal by the Building Commission.
240 The use of a powder coating system on the posts, balustrades of the fences and gates was contrary to the specifications and the building licence. However the evidence is that it is only the base plate of some of the posts that have not lasted the required warranty period. The Tribunal has no definitive evidence as to what has caused the delamination and subsequent corrosion. The respondent maintains it is caused by the corrosive effect of sea salts being left on the base plates due to regular maintenance not being carried out and the salts washed off.
241 The applicant says the respondent's use of a powder coating system instead of a galvanised system was contrary to the specifications and therefore constitutes faulty building work.
242 As this is not a contract complaint, something more than just noncompliance with the specifications is required, namely, evidence that the applicant has been detrimentally affected by the noncompliance. Had all of the areas powder coated failed, the Tribunal may have been able to conclude, without more, that it was because the posts were not galvanized as they should have been. However, there is no generalised failure and the actual cause of the failure of the paint at the base plate of the posts is not known.
243 There is no evidence that the delamination and corrosion has occurred because the respondent used a powder coat system for the gates and fences instead of using a galvanised system or that if it had used a galvanised system no delamination or corrosion, under similar circumstances, would not have occurred.
244 The Tribunal is not satisfied that the delamination and corrosion referred to in respect of the items referred to in 1.2 of the applicant's orders sought is a result of the regulated building service not being carried out in a proper and proficient manner or being faulty or unsatisfactory. The Tribunal declines to make a building remedy order in respect of this item.
245 The specification called for the areas where the AcraTex Coventry Coarse finish was used to receive a top coat of AcraShield. The specifications in respect of this item inform the Tribunal as to what standard of workmanship was expected.
246 It was stated at the outset of the proceedings that this was marketed as and designed as a luxury development. Aesthetics are important.
247 The experts agreed that using two different coating systems would mean there would always be some colour differences but the failure of the respondent to apply the AcraShield as a top coat to the AcraTex Coventry Coarse finish exacerbated what may have been a small and not noticeable difference in the colour of the two types of finishes to a significant and noticeable difference which is aesthetically displeasing.
248 The financial effect to the applicant is that the regular maintenance of recoating the AcraTex Coventry Coarse finish on the building needs to occur after seven years rather than ten and it will require two coats of AcraShield rather than one. The failure by the respondent to apply the AcraShield as required resulted in a material detriment to the applicant.
249 The Tribunal is satisfied that with regard to complaint item 2 the regulated building service by the respondent has not been carried out in a proper and proficient manner or is faulty or unsatisfactory.
250 The question of the appropriate remedy is complicated by the fact that if the building service had been carried out properly in three years or less the applicant would need to apply a top coat of AcraShield.
251 The respondent says an order in respect of remedial work should be proportionate.
252 The applicant does not address this issue and has made no submissions in response to the respondent's comment on proportionality of the remedy.
254 The Tribunal is satisfied that it is necessary and reasonable that it make a building remedy order in respect of the AcraTex Coventry Coarse finish.
255 The Tribunal has taken into account the additional cost of the extra coating now required, the earlier time that the work will have to be carried out and the possible extra cost in cleaning the surfaces and but also takes into account that a second coat to be applied would not be double the cost of one coat.
256 In considering all the above factors the Tribunal considers where it to make a monetary order the respondent should be liable for 30% of the cost of all preparation work and the application of two coats of AcraShield to the surfaces covered by AcraTex Coventry Coarse finish texture coat such application to be in a proper and proficient manner and so as to achieve a result that is not faulty or unsatisfactory.
257 Mr Walters and Dr Zarhaar gave evidence that the exterior timber soffits chosen by the architect or Stockland could never have lasted more than two years before needing recoating (first maintenance) and not seven years as required by the specifications. There was no evidence from the applicant that the respondent as a builder should have known this. There is no evidence that the respondent installed a product that it knew or should have known was not fit for purpose.
258 The evidence of Mr Perron is that he saw water damage before he moved into his unit in 2010.
259 The Tribunal finds that in 2010 there was some water damage to the soffits outside Mr Perron's apartment.
260 Dr Zarhaar's evidence was clear that when he tested the panels of the soffits that were on the sheltered side of the building the film thickness after seven years was only at maximum 10 µm. Further, in his expert opinion, if the required coatings of sealant had been applied the soffits would originally had a covering of between 120 µm and 150 µm and over seven years this could not have degraded to the point where there was only a film buildup of 10 µm.
261 The Tribunal is assisted by the specifications in establishing the standard of workmanship. Additionally it also has evidence before it as to what was recommended by the manufacturer of the product and of the experts as to what was reasonably required.
262 The Tribunal finds based on the evidence of Dr Zarhaar of the covering of the soffits to now only be a maximum of 10 µm that either an insufficient number of coats of Intergrain Ultra Clear was applied or was not applied in the appropriate manner.
263 For the above reasons the Tribunal is satisfied that the installation of the exterior timber soffits on the upper floor of the Islands was not carried out in a proper and proficient manner or was faulty or unsatisfactory.
264 In the draft orders sought by the applicant, it makes it clear that it wishes to have those soffits that cannot be satisfactorily resealed replaced and where it is possible to simply have the soffits appropriately re-sealed.
265 As an alternative it seeks to have all the soffits replaced with a suitable proprietary pre-finished external soffit product.
266 It is uncontested that no maintenance has been carried out on the soffits. It is uncontested that after between two to four years depending on the location maintenance in the form of resealing of the exterior soffits would have need to be carried out regardless of whether the soffits were properly installed.
267 However the respondent should not be relieved of its responsibility to carry out remedial work because it has taken to 2017 to have the issue of liability resolved.
268 The Tribunal is satisfied that it is both necessary and reasonable that the respondent carry out remedial work to the timber soffits.
269 Whilst the Tribunal has no definitive evidence it is probable that the remedial work that will now have to be undertaken will be more extensive/or more costly than the resealing of the soffits the applicant would have carried out as part of its regular maintenance.
270 However, to what extent the costs of the remedial work will be increased by the damage to the soffits because of the failure of the respondent to carry out the regulated building service in a proper and proficient manner or because the work was unsatisfactory or faulty, is also not known by the Tribunal.
271 The Tribunal has no evidence as to the costs involved in making good the damaged exterior soffits and the orders sought by the applicant are to have the remedial work carried out by the respondent.
272 Where the Tribunal to make a monetary order it would order the respondent to pay 50% of such remedial work.
273 The respondent has accepted liability to repair all areas where rust has appeared but says it has already properly repaired all these areas and nothing further needs to be done.
274 The respondent has also agreed it will repair the areas in the concrete behind the exterior timber soffits showing signs of rust which Dr Zarhaar agrees appear to be from rusting plastic tipped steel bar chairs; T:13; 03.08.17.
275 Further, the respondent submits that plastic tipped steel bar chairs which have not penetrated the soffit, have not corroded, and have not evidenced any other problem with the soffits themselves are not included in complaint item 4 and therefore not within the Tribunal's consideration.
276 It is the applicant's position that all the areas of the exterior concrete soffits where there are plastic tipped steel bar chairs require remedial work and seek orders accordingly.
277 The respondent (presumably in the alternative) submits that should the Tribunal find that all soffits containing plastic tipped steel bar chairs are included in complaint item 4, the Tribunal should not find that any remedial work needs to be undertaken with respect to the areas not showing signs of rust/corrosion.
278 Dr Zarhaar's opinion is that remedial work needs to be undertaken only in the areas where there is evidence of rusting. His view being that if the tips of the plastic tipped steel bar chairs were going to rust they would have done so by now. Dr Zarhaar did not provide any evidence to support his view or explain why he considered there would not be further rusting of the tips of the plastic tipped steel bar chairs.
279 There is no evidence that all the plastic tipped steel bar chairs rusted at the same time or to the same degree. The evidence in relation to the occurrence of rust or corrosion is that the visible manifestation of the corrosion of the plastic tipped steel bar chairs in the soffits occurred at different times. In the absence of evidence to the contrary, the Tribunal cannot assume that they will not rust at different times.
280 There is no evidence as to how quickly the marine environment will affect the plastic coverings on the tips of the steel bar chairs, causing them to deteriorate and the metal of the bar chair to become exposed to the air, corrode and require repair.
281 There is no direct evidence that it is because the plastic tips of the steel bar chairs have been damaged that the metal of the bar chair has protruded through the plastic covered tip.
282 There is no evidence that, as Dr Zarhaar put it 'lots of lazy grano workers' stepped on the plastic tipped steel bar chairs and pushed them to close to the surface; T:162; 03.08.17.
283 An assumption appears to have been made that the cause of the rusting of the repaired plastic tipped steel bar chairs was a failure of the plastic tip but no specific evidence was led on this point.
284 The Tribunal has no evidence as to the depth of the cover of the ends of the plastic tipped steel bar chairs are or the length of the plastic tip of the plastic tipped steel bar chairs used.
285 Dr Zarhaar confirmed that there needs to be a cover of concrete to protect the end of the bar chair and that it has to be adequate; T:162; 03.08.17.
286 Dr Zarhaar also admitted that the plastic tipped steel bar chairs that are in the cover zone have not got the required 45 millimetres of concrete protecting them against the environment and are going to corrode '[a]nd in this case, it's going to corrode inside that cover zone over a period of time. Where it hasn't even got a paint finish to keep the salts away, it's going to turn into a rust spot on the on the soffit'.
287 Dr Zarhaar does not dispute that it is a requirement of the BCA not to have metal within the cover zone; T:63; 03.08.17.
288 The evidence before the Tribunal is that the effect of having plastic tipped steel bar chairs instead of plastic bar chairs means that the cover zone is reduced to the seize of the plastic tip. It would be reduced further if the plastic tips are not all intact or are not deteriorating or otherwise exposed to the atmospheric effects of the B2 marine environment.
289 Dr Airey's evidence is also that the rusting of the plastic tipped steel bar chairs isn't restricted to the direct electrochemical effect of the plastic tipped steel bar chairs on the reinforced steel but will have a generalised effect on the concrete around it and the reinforced steel. She is of the opinion that the Islands have now reached the stage of first maintenance with respect to the concrete soffits.
290 Dr Zarhaar points out that there has been no measurement of carbonation and no measurement of the depth of chloride. All that is known is that a number of plastic tipped steel bar chairs have corroded (more than 50) and that Dr Zarhaar believes this was caused by the protrusion of the metal of the bar chair through the plastic tip. He also said it was caused by the plastic tipped steel bar chairs being too close to the surface.
291 There is no evidence before the Tribunal that when the repairs were carried out on the 'rust spots' it was found that the plastic tips were damaged.
292 The evidence is that a significant number of plastic tipped steel bar chairs have rusted whilst others to date do not show any signs of rust.
293 All experts agree that, if untreated, the rusted plastic tipped steel bar chairs will continue to rust and as Dr Zarhaar described it will have a 'wick effect' such that the rust will continue up the leg of the bar chair and into the steel reinforcing.
294 This 'wick effect' could not have occurred if plastic tipped steel bar chairs had been used as required in the specifications and BCA.
295 It is Dr Zarhaar's view that while the plastic tipped steel bar chairs will eventually rust or corrode and affect the structural integrity of the steel reinforcing the effect will be minimal and not affect the design life of the building. Dr Zarhaar points to the fact that the applicant would reasonably be required to perform regular maintenance of recoating the concrete soffits every seven to 10 years. From this, the Tribunal understands that Dr Zarhaar considers the recoating will keep a protective coating on the ends of the plastic tipped steel bar chairs and that the additional coating will help prevent oxidization through the concrete and slow the rate of rusting of the plastic tipped steel bar chairs and thus the adverse effect on the integrity of the steel reinforcing; T:57; 03.08.17.
296 The Tribunal has no evidence as to the depth of the cover of the ends (tips) of the plastic tipped steel bar chairs or the length of the plastic tip of the plastic tipped steel bar chairs used.
297 In summary the evidence before the Tribunal is that:
298 There is no evidence (as opposed to supposition) as to:
299 The Tribunal is satisfied that it is more than likely not, that:
Is the complaint restricted to those plastic tipped steel bar chairs that have, at the date of hearing evidenced problems with the soffits?
300 As was said in Pindan, the BSCRA Act is at its core consumer legislation. The purpose of the BSCRA Act is to provide consumers with a means to bring their complaints about 'the quality of performance of the regulated building service' in a nontechnical manner. It is about substance, not form.
301 In its closing submissions the respondent seeks to draw a distinction between the rust spots (the manifestation of corrosion) that have occurred before the hearing and the corrosion that may occur later. The evidence before the Tribunal applies to all plastic tipped steel bar chairs used in the concrete soffits of the Islands not just those that where the corrosion is visible or has commenced.
302 The respondent was never in any doubt as to what the complaint by the applicant is. It is not taken by surprise nor could it be said that it did not understand the original complaint was about the cause of the rust spots rather than the appearance only, of rust spots. Indeed, since the complaint was lodged further rust spots appeared and where accepted by the respondent as being part of the complaint and attempts made to remedy them.
303 At the hearing, evidence was given of further 'rust spots' being present under the timber soffits at the Islands that have not been treated and the respondent has agreed to remedy these.
304 The respondent agreed that any repairs or remedial work that needed to be done in respect of the rust spots included remedial work as to the cause of the rust spots not just to removing the actual rust spot.
305 All rust spots on the external concrete soffits and the cause of them is included in complaint item 4 and is part of the complaint referred to the Tribunal by the Building Commission.
306 The evidence before the Tribunal is that all the plastic tipped steel bar chairs will corrode and it is not restricted to those that have now or previously penetrated the soffit. It would defeat the purpose of the Act to require the applicant to wait until the corrosion appears on the surface of the soffit (in circumstances where the evidence is that the plastic tipped steel bar chairs will corrode and there is no definitive evidence why some have shown signs of corrosion early than others) to make a separate complaint in respect of each bar chair.
307 The complaint is about the cause and effect of the rust spots. The Tribunal has evidence that the cause of the rust spots is use of the plastic tipped steel bar chairs instead of plastic bar chairs. Plastic tipped steel bar chairs are used throughout the external concrete soffits. The evidence is that they will all corrode not just that some will. There evidence is that although corrosion has manifested itself in respect of some plastic tipped steel bar chairs it does not mean that the others, not currently showing signs of corrosion, will not corrode.
308 The Tribunal finds that all concrete soffits where plastic tipped steel bar chairs were required are included in complaint item 4.
309 The Tribunal accepts the respondent's submissions that where the dispute is one of workmanship and not a contractual dispute a mere departure from its contractual obligations is insufficient to establish the work was not carried out in a proper and proficient manner or was faulty or unsatisfactory.[14]
310 The Tribunal accepts that builders are not compelled to search for and install superior products over and above what is adequate for the intended purpose.[15]
311 The Tribunal also accepts that where the issue is not contractual the Tribunal should be cautious in regards to ordering remedial work to be undertaken unless the applicant has demonstrated a genuine adverse effect by reason of the building work in question.[16]
312 The use by the respondent of plastic tipped steel bar chairs in the exterior soffits was contrary to the BCA, its building licence and to the specifications of its own structural engineers. This action has had an adverse effect on the Islands by reason of the matters set out above.
313 The issue of the use of the plastic tipped steel bar chairs is not only a contractual issue; it is a workmanship issue. The BCA requires the use of plastic bar chairs in exposed or exterior areas. It is not suggested by the respondent that whilst not complying with the BCA an alternative method was used that was just as effective. Indeed, no explanation is offered by the respondent for its failure to comply with the BCA.
314 The requirements of the specifications and building licence are relevant because in this instance, they inform the Tribunal as to what is objectively considered to an appropriate standard or type of materials to be used to ensure the structural integrity of the building.
315 In some instances it could be said that noncompliance with a specification in a contract could not inform the Tribunal as to a workmanship issue.
316 The Tribunal is satisfied that the respondent by using plastic steel tipped bar chairs instead of plastic bar chairs in the exterior concrete soffits carried out the regulated building service in a manner that was not proper and proficient or was unsatisfactory and faulty.
317 The respondent submits the Tribunal should not find that any remedial work needs to be undertaken with respect to the areas not showing signs of rust/corrosion because:
318 Dr Airey gave evidence with which Dr Zarhaar agreed that the plastic tipped steel bar chairs will corrode; it is just a question of how long it will take.
319 Dr Airey and Mr Airey are of the opinion that remedial measures need to be undertaken to prevent corrosion of the plastic tipped steel bar chairs and thus the reinforcing steel and surrounding concrete in the areas where plastic tipped steel bar chairs are present in the cover zone of the concrete soffits.
320 The remedial work outlined in their report (Exhibit 1 Volume 6 page 1687) and confirmed at the hearing is designed to achieve an outcome for the applicant similar to that had the respondent complied with AS 3600 of the BCA as it was required to do. Their evidence is that that the remedial work will provide the cover for the reinforcing steel required by the BCA and the building licence. The durability of the building will be closer to that which would have been achieved had the respondent used plastic bar chairs.
321 The Tribunal is satisfied that it is both reasonable and necessary for the respondent to carry out remedial work in accordance with the recommendation of Dr Airey and Mr Airey as set out in their report as in Exhibit 1 pages 1700 to 1701 including any modifications agreed at the hearing to all the external soffits where plastic bar chairs were required to be used. The Tribunal will hear further from the parties as to the order to be made.
322 The Tribunal notes that the respondent has accepted liability for the known rust spots and the only issue in respect of those that have been repaired is whether they need to have further remedial work performed.
323 The evidence from the experts differed somewhat as to the method to be used in remedying those areas of the soffits that have shown signs of corrosion. All agreed that any rust or corrosion present on a bar chair must be removed. Dr Airey and Mr Airey proposed and Dr Zarhaar accepted that the corroded plastic tipped steel bar chairs needed to be cut back to 30 millimetres; T:146; 03.08.17.
324 Dr Airey and Mr Airey considered you need to actually measure how far you cut in to the bar chair. Dr Zarhaar was of the view that you had to go far enough to ensure you had removed all the rust/corrosion and that to go to 30 millimetres would give a greater degree of confidence of that; T:147; 03.08.17. It was agreed by all experts it is essential that the steel must be clean.
326 The system that was used had some additional steps that were not considered by the experts as being necessary. It was agreed by the experts that it was not necessary to use the Galmet Ionize Sealer or the Dulux Weather Max HBR but its use would not have a detrimental effect.
327 The Dulux Luxepoxy coating was also agreed by the experts as not being the correct type of epoxy to use as it is not a zinc rich epoxy which it was agreed was required. Dr Zarhaar did not explain why, given he agreed a zinc rich epoxy, was necessary and had not been used he was of the opinion that the system of repair carried out by the respondent was adequate.
328 Another issue of the repair was the area around the bar chair to be removed. Dr Airey and Mr Airey are of the opinion that a square area should be saw cut around the rusting bar chair of approximately 30 millimetres to 40millimetres to remove in full any contaminated concrete (Exhibit 1page 503). At the hearing, Dr Airey agreed that it could be saw cut or drilled out which Dr Zarhaar considered more cost effective.
329 Specialist concrete repair contractors were not used for the repairs. No records were kept of the repairs to the point that the number of repairs carried out is uncertain.
330 The repairs were supervised by Mr Terace, who gave evidence at hearing that:
331 Mr Terace was taken through the steps of the repair in detail and asked particularly about time intervals between the various stages of the repair. He said that the employees carrying out the repairs cut back the plastic tipped steel bar chairs to between 10 centimetres and 15 centimetres, as was required by Dr Zarhaar's method.
332 Mr Terace did not observe or oversee a single repair from start to finish. His evidence as to the procedures followed by the workers was: they would start by 'chip away the concrete', move on to the next spot showing rust and again chip the concrete away and then when all the concrete had been removed and the plastic tipped steel bar chairs were exposed they would go back to the first plastic tipped steel bar chair and start the next step in the repair procedure.
333 No formal measure was taken of the depth of the concrete they chipped away around each bar chair. No cleaning was carried out of salts or other contaminates around the repair area. No cleaning was done of a repair at the various stages. No note or record was taken of the time between each stage in the repair system. No records were kept of the repairs to the point that the number of repairs carried out is uncertain.
334 The Tribunal cannot have any confidence that the repairs were carried out exactly to the requirements set down by Dr Zarhaar given:
335 The system of repair as described by Mr Terace had significant flaws in it due to the lack of integrity as to the depth of the cut, the lack of cleanliness of the site the necessity of which was described by Dr Airey the epoxy used was not rich in zinc as was agreed by Dr Zarhaar should be used and the time lapses between the different coats of the system meant the possibility of further contamination and corrosion before the repair was finished.
336 The combination of the lack of integrity in the system of repair as described by Mr Terace and the flaws in the repair system itself leads the Tribunal to conclude and it is satisfied that the rust spots on the concrete soffits have not been satisfactorily addressed.
337 The Tribunal finds it is reasonable and necessary for the remedial work already carried out on 'rust spots' to be redone in a proper and proficient manner and in compliance with the system outlined by Dr Airey and Mr Airey.
338 The skirting board in the lower level of apartment 17 was swollen and showed evidence of previous water ingress. Mr Machall, the applicant's expert, however was unable to do more than speculate from where or how the water had entered; T:120; 02.08.17. When asked by the Tribunal if he was able to form an opinion as to the cause of the swollen skirting board he said he was not; T:119; 02.08.17.
339 Mr Machall's evidence was that he found a post or veranda post where the water proof membrane appeared to not continue up the post as it should but he did not say whether he considered this was the cause of the reported leaks or could cause any future leaks.
340 Mr Machall conducted no testing to see if there was an excess of or higher than would be expected moisture content in the walls.
341 The applicant's expert did not or could not say what the cause of the leaks was. The onus is upon the applicant to prove the leaks are caused by defective workmanship. The mere presence of a leak or of water ingress in these circumstances does not without evidence of the cause of the leak lead the Tribunal to infer it is as a result of faulty or improper or unsatisfactory workmanship.
342 The Tribunal is not satisfied that the respondent carried out a building service in respect of the cause of any leak(s) in apartment 17 that was faulty or unsatisfactory and declines to make a building remedy order.
343 Mr Machall also gave evidence in respect of the reported leaks in the storage area of the building or carpark area as it was sometimes referred to.
344 He observed the reported leaks in store 2 through the grill and could see staining (effervescence) on the far wall but couldn't say if it was due to a leak that had been repaired or whether the effervescence was due to ongoing water ingress.
345 In respect of store 1, Mr Machall was able to gain access but couldn't say if the effervescence on the wall was due to a leak that had been repaired or whether the effervescence was due to ongoing water ingress.
346 Again no moisture testing was conducted so that Mr Machall was unable to say if there was a current leak as opposed to a past leak. He also gave no evidence as to the possible or probable cause of the leak(s) if present.
347 The Tribunal is not satisfied that the respondent carried out a building service in respect of the cause of any leak(s) in in the store room (garage) that was faulty or unsatisfactory and declines to make a building remedy order in respect thereof.
348 There was a leak in connection with one of the swimming pools for which liability is accepted by the respondent however the cost of the remedial work is not.
349 The applicant alleges it had no choice but to arrange to have the leak repaired as the respondent had refused to do so.
350 The respondent produced emails which showed that whilst it had originally refused to accept liability for the leak at the lap pool it did eventually do so. It did not offer to carry out any investigations as to the cause of the leak.
351 The respondent says it should only be liable for the cost of remedial work that it would have incurred had it been given the opportunity to repair the leak.
352 The quotation for repairs from the respondent's plumber does not include the costs of investigating the leak, some $440 which were reasonably incurred by the applicant.
353 The Tribunal is satisfied that the respondent was not prepared to investigate the cause of the leak and the applicant should have its cost in respect of the investigation work. The Tribunal is satisfied, however that the respondent was prepared to repair the leak and therefore it is the cost that would have been incurred by the respondent that the applicant is entitled to be reimbursed that is $1,140.70 plus $440 being a total of $1,580.70. There will be a building remedy order pursuant to s 38(1)(b) in the sum of $1,580.70.
354 At the conclusion of their evidence it was accepted by the experts that the decking around the swimming pools had not performed the way it should. There was physical evidence of serious distortion and excessive shrinkage noted across the decking indicating that the degree of movement experienced by the boards, once laid, exceeded that which is acceptable.
355 Dr Zarhaar considered that in both buildings, two thirds of the boards need replacing. He also agreed that if the boards in the areas were not distorted that they needed to be relaid because of the width of the gap caused by shrinkage that it may not be economical to remove and relay those boards rather than replace them.
356 Dr Zarhaar also relevantly made the point that if you were to reuse the timber it would have to be removed with the intention of reusing it rather than with 'a sledge hammer'; T:125; 03.08.17.
357 The Tribunal is satisfied that it is more likely than not that the failure of the decking occurred due to the installation of boards with moisture content value significantly exceeded those recommended.
358 However, regardless of whether the Tribunal is correct in its conclusion as to the cause of the failure of the decking it was accepted by the respondent's expert Dr Zarhaar, that for no reason attributable to the applicant or a third party, the decking has not performed as it should and was not fit for purpose.
359 Dr Zarhaar's opinion that the amount of boards tangentially cut either contributed to or caused the decking to not perform does not assist the respondent. The respondent was responsible for the selection and lying of the boards. It was required to provide decking fit for purpose.
360 For the above reasons the Tribunal is satisfied that the decking installation was not carried out in a proper and proficient manner or was faulty or unsatisfactory.
361 Having found a regulated building service has been not carried out in a proper and proficient manner or was faulty or unsatisfactory the Tribunal is required to consider if a building remedy order ought to be made and if so for what amount.
362 Given the evidence as to the state of the decking and the respondent's own expert agreeing it should all be replaced, the Tribunal considers it reasonable and necessary to make a building remedy order.
363 As the remedial work has already been completed, the Tribunal needs to determine what is a reasonable cost of the remedial work.
364 The applicant submits it was necessary for it to arrange for the work to be done as the respondent refused to carry out the remedial work.
365 The respondent's position is that the applicant did not need to carry out the works and it should have awaited the outcome of these proceedings and therefore the cost of the remedial work should be what it would have cost it.
366 The evidence before the Tribunal that there were areas around the pool that were either required to not be used by the local authority or it was not advisable to use those areas for safety reasons. Additionally, the state of the decking would have significantly affected the amenity of the area.
367 The Tribunal is satisfied that it was reasonable for the applicant to have carried out the works given the respondent's refusal to do so.
368 Although the Tribunal is satisfied the applicant's actions in having the work undertaken, it is still for the Tribunal to consider if the costs incurred by the applicant are fair and reasonable.
369 Mr Wade claimed he had provided quotes for the variations to the original quoted work but was not able to produce a quote for any of the claimed variations.
370 His quote for the original work and all invoices claimed the decking area he had performed work on was 420 m².
371 Mr Murphy, an employee of the respondent, gave evidence that he measured the pool decking area in question and that it was about 270 276 m². His measurement was based on the plans.
372 It was not suggested by the applicant that the decking was not constructed in accordance with the plans or that the area shown on the plans was different to that constructed.
373 Mr Wade's evidence in respect of the cost of the replacement of the decking was entirely unsatisfactory. Mr Wade replaced the decking but produced no records to support his evidence as to the quantities of timber he had purchased or the price he paid for it.
375 Mr Wade was not able to explain any of his invoices for the additional work he claims to have performed that was not included in the original quote. He was unable to or did not produce any invoices for the materials he said he purchased. He could not recall how long work took and the timing of the work that he did describe did not match the invoices he issued to the applicant.
376 The Tribunal prefers the evidence of Mr Murphy to that of Mr Wade as to the area of decking that was replaced because Mr Murphy was able to corroborate his evidence with documentation showing the quantity of timber originally installed and was consistent with the measurements taken from the plans.
377 The Tribunal is not satisfied that the invoices Mr Wade submitted to the applicant accurately reflected the work he performed at the Islands or that the area of the decking that he worked on was 340 m² as claimed in his invoices.
378 The Tribunal accepts as a proposition that it might have been more economical to remove the decking without taking care to not damage the subframe; however we have no evidence about what the different costs might be.
379 It was put by the applicant that the quotes provide by the respondent may possibly reflect a better price than the applicant could have obtained however that is something the Tribunal is unable to determine or quantify given the complete unreliability of Mr Wade's evidence.
380 Neither Mr Wade's original quote nor the one from TFP are itemised. The lack of itemisation has caused the Tribunal some concern and has hindered the Tribunal from being able to determine the reasonableness of the quotes.
381 The costings put forward by the respondent are based on quotations for 272.5 m² (measurements taken from the drawings) together with an explanation for the calculations for the labour and other associated costs that would have been necessary.
382 The original sub-frame was also replaced by the applicant. It was accepted by both parties that it would have been necessary to change or modify the sub-frame to accommodate the new decking that was laid.
383 The applicant alleges however, it was necessary to replace the subframe because parts of it were found to be rotten when the decking was removed.
384 The respondent maintains it was replaced because the new decking, being a composite product required a different type of sub-frame to the one used for the Pelawan decking.
385 The applicant relied upon the evidence of the installer of the decking, Mr Wade, in support of its position that the decking was replaced as a matter of necessity owing to the poor condition of the sub-frame.
386 Mr Wade's evidence in respect of the replacement of the sub-frame was vague and contradictory. He was unable to provide any information about the quantities of materials he purchased, and did not provide any receipts or orders for materials. Mr Wade was unable to provide any satisfactory explanation for how he costed the replacement of the subframe.
387 Mr Wade's explanation for when he formed the view that the subframe would need replacing was not consistent with the timing of the reports from the project manager.
388 The Tribunal accepts that some portion of the sub-frame may have needed replacing either because it had rotted away or was damaged by the removal of the decking. Mr Wade in oral evidence thought that he might have had to replace half the subframe.
389 The Tribunal is not satisfied that the applicant was required to replace the sub-frame as claimed by the applicant.
390 The Tribunal is unable to rely upon Mr Wade's evidence in respect of the cost of replacing the decking for the reasons set out above.
391 The Tribunal accepts the evidence of the respondent as to the cost of replacing the Pelawan decking with Merbau which is a similar product to the Pelawan it replaced.
392 The Tribunal is satisfied that a reasonable price for the work that was required to be completed to remedy the faulty or unsatisfactory building service is that put forward by the respondent with an allowance for 276m² of decking as was conceded might be needed by Mr Murphy in his oral evidence that is $50,403 plus additional allowance for the extra meterage rounded to $51,000.
(a) the steel pergolas to each building in respect of which the respondent has expressly excepted liability and including:
(i) the item(s) defined in particular 1 in the Master Painters and Decorators Association Report dated 4 February 2013 at page 365 of Volume 2 of Exhibit 1;
(ii) the items defined in particular 11 in the Master Painters and Decorators Association Report at page 368 of Volume 2 of Exhibit 1;
(iii) the item(s) defined in particular 15 in the Master Painters and Decorators Association Report at page 369 of Volume 2 of Exhibit 1;
(b) the steel walkways to each building which run perpendicular to the pergolas and including the walkways as defined in particular 1 in the Master Painters and Decorators Association Report dated 4 February 2013 at page 365 of Volume 2 of Exhibit 1,
has occurred as a result of the regulated building service not being carried out in a proper and proficient manner or being faulty or unsatisfactory.
I certify that this and the preceding [392] paragraphs comprise the reasons for decision of the State Administrative Tribunal.

This complaint relates to the painting of five different areas. The Tribunal found the regulated building service by the respondent in respect of the pergolas, walkways, structural steel elements to the western elevation of the Islands and the western elevation of Block 1 has not been carried out in a proper and proficient manner or is faulty or unsatisfactory and the respondent is required to carry out the necessary remedial work namely the painting of those surfaces.
The Tribunal found the regulated building service by the respondent in respect of this item has not been carried out in a proper and proficient manner or is faulty or unsatisfactory and that for the reasons set out in Pindan No 2 the respondent is liable for 30% of the costs of the now necessary remedial work.
The Tribunal found the regulated building service by the respondent in respect of this item has not been carried out in a proper and proficient manner or is faulty or unsatisfactory and that for the reasons set out in Pindan No 2 the respondent is liable for 50% of the costs of the now necessary remedial work.
The Tribunal found the regulated building service by the respondent in respect of this item has not been carried out in a proper and proficient manner or is faulty or unsatisfactory and for the reasons set out in Pindan No 2 it is both reasonable and necessary for the respondent to carry out remedial work in accordance with the recommendation of Dr Anthea Airey and Mr Peter Airey as set out in their report in Exhibit 1 pages 1700 to 1701 including any modifications agreed at the hearing to all the external soffits where plastic bar chairs were required to be used. Additionally the Tribunal found it reasonable and necessary for the remedial work already carried out on 'rust spots' in the concrete soffits to be redone in a proper and proficient manner and in compliance with the system outlined by Dr Airey and Mr Airey.
This complaint was dismissed other than in respect of the swimming pool leak. The Tribunal made a building remedy order pursuant to s 38(1)(b) of the BSCRA Act in the sum of $1,580.70. On 13 April 2018 an order was made by the Tribunal that the payment of the $1,580.70 was to be paid by the respondent to the applicant by 8 May 2018.
The Tribunal found the installation of the pool decking was not carried out by the respondent in a proper and proficient manner or was faulty or unsatisfactory. The Tribunal further found that the cost of the required remedial work necessary to remedy the faulty or unsatisfactory building service was $51,000. On 13 April 2018 an order was made by the Tribunal that the payment of the $51,000 was to be paid by the respondent to the applicant by 8 May 2018.
(1) If the Building Commissioner refers a building service complaint to the State Administrative Tribunal, the Tribunal may
(a) if the Tribunal is satisfied that the regulated building service that is the subject of the building service complaint has not been carried out in a proper and proficient manner or is faulty or unsatisfactory, deal with the building service complaint by making a building remedy order; or
(b) otherwise, decline to make a building remedy order.
(1) A building remedy order consists of one of the following
(a) an order that a person who carried out a regulated building service remedy the building service as specified in the order;
(b) an order that a person who carried out a regulated building service pay to an aggrieved person such costs of remedying the building service as the Building Commissioner or State Administrative Tribunal, as the case requires, considers reasonable and specifies in the order;
(c) an order that a person who carried out a regulated building service pay to an aggrieved person a sum of money specified in the order to compensate the aggrieved person for the failure to carry out the building service in a proper and proficient manner or for faulty or unsatisfactory building work.
(2) A building remedy order may require that the order be complied with within a time specified in the order.
(3) A person who is not a building service contractor may arrange for a building service to be carried out for the purpose of compliance by that person with a building remedy order referred to in subsection (1)(a) despite the Building Services (Registration) Act 2011 section 7.
The main objectives of the Tribunal in dealing with matters within its jurisdiction are
(a) to achieve the resolution of questions, complaints or disputes, and make or review decisions, fairly and according to the substantial merits of the case; and
(b) to act as speedily and with as little formality and technicality as is practicable, and minimise the costs to parties; and
(c) to make appropriate use of the knowledge and experience of Tribunal members.
(1) The Tribunal is bound by the rules of natural justice except to the extent that this Act or the enabling Act authorises, whether expressly or by implication, a departure from those rules.
(2) The Evidence Act 1906 does not apply to the Tribunal's proceedings and the Tribunal
(a) is not bound by the rules of evidence or any practices or procedures applicable to courts of record, except to the extent that it adopts those rules, practices or procedures or the regulations or rules make them apply; and
(b) is to act according to equity, good conscience and the substantial merits of the case without regard to technicalities and legal forms.
(3) Without limiting subsection (2), the Tribunal may admit into evidence the contents of any document despite noncompliance with any time limit or other requirement specified in the rules in relation to that document or service of it.
(4) The Tribunal may inform itself on any matter as it sees fit.
(5) To the extent that the practice or procedure of the Tribunal is not prescribed by or under this Act or the enabling Act, it is to be as the Tribunal determines[.]
By what date should the respondent carry out the required remedial work as set out in paragraph 1 of the orders in the Pindan Nos 2 decision?
Should the respondents have leave to reopen their case to adduce further evidence as to whether a building remedy order should be made?
If the respondent is not granted leave to reopen its case what is the appropriate building remedy order?
Was the omission of the fresh evidence deliberate or otherwise?
Accordingly, even in a statutory context where the presumptive position is that no costs will be ordered, generally speaking, the question is whether, in the particular circumstances of the case, it is fair and reasonable that a party should be reimbursed for the costs it incurred. The onus is on the party seeking an order in its favour.
Pergolas and walkways, structural steel elements to the western elevation to Blocks 1 and 2
(a) the steel pergolas to each building and respect to which the respondent has expressly accepted liability and including:
(i) the item(s) defined in particular one in the Master Painters and Decorators Association Report dated 4 February 2013 at page 365 of Volume 2 of Exhibit 1;
(ii) the item(s) defined in particular 11 in the Master Painters and Decorators Association Report dated 4 February 2013 at page 368 of Volume 2 of Exhibit 1;
(iii) the item(s) defined in particular 15 in the Master Painters and Decorators Association Report dated 4 February 2013 at page 369 of volume 2 of Exhibit 1; and
(iv) the steel walkways to each building which run perpendicular to the pergolas in and including the walkways as defined in particular one in the Master Painters and Decorators Association Report dated 4 February 2013 at page 365 of volume 2 of Exhibit 1.
(a) remove any cladding that obscures any external concrete soffits from visual inspection for rust spots or corrosion staining, and following such removal undertake a visual inspection of the soffit to check for rust spot or corrosion staining;
(b) carry out remedial work to any rust spots or corrosion staining in accordance with the remedial recommendations of Dr Airey and Mr Airey as set out in their reports dated 18 April 2016 and 17 July 2017 in Exhibit 1 pages 602 to 606 and 1687 to 1705 including any modifications agreed at the hearing;
(c) in respect of those previously repaired rust spots or corrosion staining to carry out remedial work in accordance with the remedial recommendations of Dr Airey and Mr Airey as set out in their reports dated 18 April 2016 and 17 July 2017 in Exhibit 1 pages 602 to 606 and 1687 to 1705 including any modifications agreed at the hearing; and
(d) in respect of the external concrete soffits that have not or do not show signs of corrosion or where no rust spots have appeared carry out remedial work to those external concrete soffits in accordance with the remedial recommendations of Dr Airey and Mr Airey as set out in their report dated 17 July 2017 in Exhibit 1 pages 1687 to 1705 including any modifications agreed at the hearing.
