Plaintiff's evidence
8The plaintiff swore two affidavits and was cross-examined.
9Mr Kanatlarovski said that on or about 13 April 2010 he and his wife purchased land at 105 Simmat Avenue, Condell Park with the intention of building a home for themselves and their family. He said that he had never before been involved in the construction of a house.
10Prior to the commencement of any work on the site, he obtained Development Consent from Bankstown City Council on or about 7 September 2010 and an Owner Builder Permit from Fair Trading New South Wales dated 16 September 2010.
11In the course of preparation for the construction works he obtained a structural design for a concrete slab from an engineer by the name of Mr Nikolai Koloff. It was dated 26 October 2010. Mr Kanatlarovski said that he had never constructed or been responsible for constructing a concrete slab nor did he know how to prepare or use concrete.
12The plaintiff said that in late October and early November 2010 he obtained four written quotations for the construction of the concrete slab. The quotations were not in evidence but the plaintiff said that he had obtained a quote from someone called Andrew for $31,000.00. Andrew said "$31,000.00 is a rough price. It includes the cost of me hiring machines and other people to help me out."
13The plaintiff said that he obtained a quotation from Angele Paceskoski ABN 92 390 284 293 in the amount of $42,000.00. The plaintiff also said he obtained a quotation from Speedy Formwork Pty Ltd ABN 71 143 111 219 for $52,000.00. He was concerned to save costs and sought a further quotation from the defendant.
14The plaintiff said that he was introduced to the defendant by his mother-in-law who was a friend of the defendant's wife.
15In October 2010 he attended the defendant's property and he said they had a conversation in which he said words to the effect, "I heard you do concreting work. I am an owner builder. I have already gotten a few quotes so I can compare prices. Can you give me a quote for you to build a concrete slab for me?"
16The defendant said, "If you give me the plans I can look at the plans and come up with a quote for you." The plaintiff said, "Do you have lasers and all the equipment needed to build a slab?" The defendant said, "I've got all that. I've got a backhoe. I can even do the excavation, drilling and forming up myself. I'll do it all included in the one price." The plaintiff said, "Where is your backhoe?" The defendant said, "It is on another job in Padstow. I'll have to drive it over and I might have to leave it on your property." The plaintiff said, "Do you understand all the requirements?" The defendant said, "I've got all those things covered." The plaintiff said, "What exactly would you be charging me for?" The defendant said, "I charge five hundred dollars labour per day, plus I will oversee all the work on site."
17The plaintiff then gave the defendant the plans and said, "Have you ever done this before?" The defendant said, "I can do this. I have done it a few times before. It shouldn't be too hard. I will consider the plans and come up with a quote."
18The plaintiff said that he formed the opinion the defendant was an experienced concreter and backhoe operator who appeared to own his own machinery. He said he understood that fact both from what the defendant said and from observations that he made when he attended the defendant's property.
19The plaintiff said that on 1 November 2010 the defendant gave him a written quotation for $31,400.00 for the concreting works plus a further amount of $1,600.00 as a contingency for additional soil removal if required.
20The plaintiff said that he remembered that it displayed an Australian Business Number, a licence number and some insurance details for the defendant. Mr Kanatlarovski's brother in law, Mr Hrisikovski, confirmed in an affidavit that he had seen the quotation although he could not remember any details about what it contained. He was not required for cross-examination.
21The plaintiff said he did not retain a copy of the quotation, but nevertheless he made some diary notes about. The diary notes were in evidence.
22The plaintiff said that on or about 8 November 2010 he decided he would engage the defendant to do the work because he believed that his price was reasonable compared to the other quotes he had obtained, that he was an experienced and licensed concreter and that he would save costs as he operated his own machinery for digging, drilling and excavating. He also formed the view that the other quotations he had received were unreasonably expensive and the other parties were less experienced and less professional.
23The plaintiff said he had a conversation on about the same day with the defendant in which he said, "Mate, you got the job." The defendant said, "Thank you. I hope I can give as good a job as I have given previous customers." The plaintiff said, "I hope you can." The defendant said, "I will try and give you the best job I can. I am very experienced. I have been doing this for about thirty years."
24The plaintiff said they discussed payment and he asked whether he could pay by instalments and the defendant said, "Yes, you can pay me in stages. The first payment can be on the commencement of pier work. The second can be made when I order the steel frames, waffle pods and foam for the formwork for the slab. The third payment can be made before the commencement of pouring the concrete for the slab, and the fourth payment can be made after completion of the slab."
25The plaintiff said, "That is reasonable. I agree. I will pay before each stage to help fund the concreting work. If you need any more money just let me know." The defendant said, "No, I shouldn't need any more money. I will try to keep to the quoted price."
26The defendant commenced the construction work on or about 27 November 2010.
27On or about 10 December 2010, the plaintiff visited the defendant who was working on a property at 4 Panorama Parade Padstow in order to pay him an instalment. He said that he observed Mr Vasilkov to be working on the construction of a concrete slab. He said he was pouring concrete for the piers and did not appear to be taking instruction from anyone.
28On 11 December the defendant said to the plaintiff, "I need another two thousand dollars. I underquoted myself for the cost of removing dirt. Please pay me an extra two thousand dollars."
29The plaintiff apparently agreed to the additional $2000.00 and thus the contract sum, adjusted, was $35,000.00.
30Mr Kanatlarovski said that between 10 December 2010 and 5 January 2011 he paid $25,000.00 in three instalments - one of $5,000.00 and two of $10,000.00 each.
31The plaintiff said that on or about 17 December 2010 he attended the property with the defendant. He said he observed piers poking out of the ground. Some of the waffles were at angles. He said, "I observed the defendant cutting away and shaving the foam away in some parts."
32He said that he said to the defendant, "Should the foam be sitting on the piers like that? The waffles look very uneven." The defendant said, "It's all good. It will come down to the level it should be on." The plaintiff said, "Is this the finished level?" The defendant said, "No, I still need to complete the formwork and there are just a few things left I need to do." The plaintiff said, "What about the side of the slab where the brickwork will sit? The formwork looks wrong." The defendant said, "It's okay. The brickies will sort it out when bricking up. It's all good. Don't panic. It will all be sorted out at the pour."
33I should point out at this stage that the references to 'waffle' and 'foam' are references to a type of slab construction ('waffle pod') that involves concrete being poured onto a series of foam boxes or pods, set out in a grid pattern.
34On 17 December 2010 the plaintiff was present at the site with the private certifier who came to inspect the reinforcement for the slab. Later in the afternoon and before the defendant left the property, the plaintiff said to him, "I'm still worried about the formwork." The defendant said, "You have nothing to worry about. Leave it to me on the pour."
35The plaintiff tendered some diary notes which tended to support the evidence that he gave about the conversations on those days.
36On 24 December 2010 the plaintiff visited the property and saw some long cracks in the slab and saw that some of the steel reinforcement was sticking out.
37The plaintiff said that on 27 December he visited the property and measured the rebate in the slab. He said it measured 90mm when it should have measured 150mm according to the plans. Similarly, he measured the step down to the garage area which recorded a measurement of 50mm when the plans showed 170mm.
38The plaintiff said that he visited the property on 5 January 2011 and made further observations about the cracks and the steel reinforcement in the concrete slab and took some photographs. He said he telephoned the defendant and said, "I can see cracks and there is steel poking up out of the slab. I am worried about this." The defendant said, "The guys helping me with the pour must have stepped on the steel which popped up when the concrete was poured. Cracking is a normal thing. Don't worry. The slab was built according to the engineer's plans."
39The plaintiff took photographs on or about the same day. They were in evidence.
40The plaintiff said that on or about 12 January the defendant spoke to him by telephone and said that he wanted to be paid. The plaintiff said, "I can't pay you. I'm on holidays." The plaintiff also said, "I want you to sign an agreement to show that you take full responsibility for the workmanship and quality of the concrete slab you constructed." The defendant said, "No. I will not sign anything until you pay the full amount due."
41Worried about the quality of the work, Mr Kanatlarovski did not pay any further money.
42On or about 19 January 2011 Mr Kanatlarovski obtained some core samples of the concrete slab. The core sample disclosed that the slab was thinner than 85mm in a number of areas, contrary to the plans. He also measured the step down from the main house area to the garage. The step down measured 50mm whereas the plans prescribed 150mm.
43The plaintiff and the defendant had a meeting on site on 22 January 2011. The plaintiff said that the defendant said, "I don't know what happened. I don't know how this happened. I must have made a mistake. I don't know how this went horribly wrong here. Don't worry, I'll fix it." He also said that the defendant said, "I'll call up my insurance on Monday morning and get them to fix this. If they won't pay for it I'll fix it myself." He also said, "I will contact the engineer and get his recommendations."
44Nothing happened and on 28 January the plaintiff telephoned the defendant and asked him for his surname and licence number. The defendant said, "My surname is Vasilkov. I'll call you back with my licence number details. My licence number is in my wallet and I'm not close to my wallet."
45The plaintiff contacted the Department of Fair Trading on 28 January. The parties agreed that the defendant does not and did not have a licence issued by the Department of Fair Trading as a concreter. His only licence was as a backhoe operator and earthmover.
46Mr Kanatlarovski said that he telephoned the defendant again on 28 January and asked him once more for his licence number. The defendant said, "I still don't have my wallet. I left it at home." The plaintiff said, "That's not good enough." The defendant said, "I don't have to give it to you anyway." Mr Kanatlarovski said that he said something else, then heard the defendant laughing as he said, "I've lost money as well. I want the ten thousand dollars you owe me. The people I owe money to are not happy people. I can send them over to your place." The plaintiff said, "What you owe to other people is not my problem. You're asking for money when you're not even licensed." The defendant said, "I've done the job. I want the money. One way or another I will get my money off you." The plaintiff said, "Is that a threat?" The defendant said, "Take it however you want." The plaintiff said that he heard the defendant laugh again.
47Mr Kanatlarovski's diary note for 28 January broadly confirms the content of the conversation.
48The plaintiff said that the private certifier refused to certify the slab and the design engineer advised that the slab should be removed and replaced. The design engineer's report was in evidence. It said, inter alia,
"In mid January 2011 after the concrete was pored [sic] the owner of the above property, Mr Peter Kanatlarovski called me and expressed concern that some of the reinforcement was still exposed, some structural cracks occurred along the concrete surface. I instructed him to drill some core holes on various placed along the garage floor and main floor [sic]. The results were as follows:-
Garage floor
· 2 holes indicated a thickness of 43mm
· third hole on a beam between waffle pods at 270mm
Main floor
· 2 holes indicated a thickness of 43mm
· 2 holes indicated a thickness of 65mm
· 2 holes indicated a thickness of 70mm
On 20 January 2011 I inspected the property and certified that the above thickness measurements are correct and do not comply with current Australian Standards: AS3600-2001- concrete structures code, and AS3700-2001 - masonry structures. Some of the reinforcement was exposed (no min of 30mm cover).
Recommendations:
Since the topping of the floor slab is not an option (refer to Bankstown Council's Town Planner, Mr Alan Ho's, approval condition) the only option is to remove the entire concrete works, replace the plumbing, erect new slab as per approved structural drawings."
49The private certifier was also of the opinion that the slab could not be topped or thickened. In a letter dated 3 February 2011 he said, "I must bring to your attention that your DA Application was particularly a hard DA to comply with, due to the fact in which we had to maintain strict setbacks and relative finished floor levels, which were enforced by Bankstown City Council, in order not to overshadow neighbouring properties. I clearly remember that we were 'just' able to comply. I strongly recommend that topping up the concrete slab will not be a sound solution as it will raise the finish floor level and hence not comply with Council's strict DA conditions (bearing in mind that the concrete slab was supposably [sic] poured to the correct levels). Another concern, I have is that the step down from the ground floor slab to the garage slab is not to approve DA or CC plans. [sic]"
50The plaintiff said that despite several requests over the period 18 December 2010 to 27 January 2012 to the defendant to rectify the concrete slab, he did not do so and the slab remained in an unusable state for more than a year.
51On 27 January 2012 the plaintiff's solicitors informed the defendant's solicitors that he intended to remove the concrete slab and starting on 6 February the concrete slab was cut up into pieces by heavy machinery.
52The plaintiff said that the pieces were removed by him from the property and dumped in a recycling facility.
53The plaintiff said that he carried out the majority of the removal of the concrete works either on his own or with the help of family and friends in order to save costs. He said that work took approximately two months to complete and he incurred costs and expenses associated with it. He said his costs totalled $80,534.28, the majority of which related to the machine hire for the removal of the concrete and foam and the removal of dirt and piers and replacement of the plumbing work.
54The plaintiff prepared a schedule of his losses. He was cross-examined at length about it. He conceded that with respect to his claim for Water Rates and Council Rates and mortgage repayments, he would have had to pay for them irrespective of whether the slab was defective or not. With respect to the engineer's costs he said that it was for the creation of the new drawings and inspection of the new slab and to ensure that it complied with the new drawing. The date of the invoice did not match the date at which the plaintiff said the replacement slab was poured and he was not able to explain why a new drawing was necessary. This aspect of his evidence as to rectification costs was unsatisfactory.
55Part of Mr Kanatlarovski's claim for damages included the replacement of plumbing and stormwater lines that had been damaged and removed in the course of the demolition of the defective slab. He was cross-examined about this aspect of his claim in some detail. It was put to him that the stormwater piping was not installed until after the slab was found to be defective and after he had started to dig around it. The plaintiff said that all of the stormwater pipes around the house had been placed but when he started to dig along the edge of the slab in order to install the stormwater pipe nearest the fence he noticed that the concrete actually got thinner and this observation led to him organising some core drills to check the thickness of the slab.
56The plaintiff was adamant that the balance of the storm water piping had been installed before he realised the slab was defective. It was put to him that there was no reason why the plumbing under the soil and the trenches could not have been left in situ, but the plaintiff said once he started to pull up the slab the plastic and the copper pipes came with it and he said "we could not save the plumbing - that's all I can say."
57The plaintiff was cross-examined about the removal of the slab. He said that an acquaintance with a concreting business cut it up for him with a saw then he scraped the foam away from the concrete and then hired somebody to take it all away. In order to make sense of this evidence it is necessary to know that when concrete is poured onto the foam waffle, the foam adheres to the concrete.
58It was put to Mr Kanatlarovski that scaping the foam from the concrete was an inefficient way of disposing of the slab. He answered that at first, he had taken a load of concrete (to which the foam was still adhered) to the tip but the cost of $1,000.00 to dump 5 tonnes was too much for him. He said; "I didn't have the money to do that" and that he discovered that the cheapest and simplest way to get rid of it was to flip the sections over, scrape the foam off, recycle the foam and recycle the concrete. He said the tipping cost for recycling was considerably cheaper.
59In respect of his claim for an excavator, It was put to him that he did not have an excavator running on site for 9 hours a day for 9 days. The plaintiff said that he did and he was using its bucket to scrape the foam from the concrete.
60Mr Kanatlarovski did not lead any evidence on the cost of replacing the actual slab.
