Background
7 The Department was awarded a contract with the Department of Land and Water Conservation to provide project and construction management services in relation to the construction project at the premises.
8 On or about 16 July 2002, Mamfe was awarded the contract for the construction project by the Department.
9 In or about June 2002, Crouch designed an unusual modular scaffolding system including a curved platform to fit around the concrete reservoir ( scaffold platform ). Crouch designed the scaffolding in his capacity as an employee of Mamfe, as part of the undertaking of Mamfe.
10 In approximately late July 2002, Allens Welding manufactured the modular scaffolding.
11 The scaffolding was used on a regular basis at the premises, being erected and re-erected to suit various tasks associated with the construction project.
12 The scaffolding consisted of two scaffold towers, chained to the reservoir wall, supporting the curved scaffold platform. There was a handrail down the length of the scaffold platform, however, no handrails at the ends of the platform.
13 On or about 14 November 2002, Will visited the premises to install the first hold down bolts for the main centre beam for the reservoir roof. Whilst at the premises, Will, who was also the OHS Officer for the Defendant, had a conversation with Crouch to clarify the method of scaffolding to be used to the outside of the concrete reservoir.
Erection of scaffolding
14 On or about 3 December 2002, Crouch, Ritchie and Reynolds erected two scaffolding towers. Each tower ( scaffolding tower ) consisted of four individual scaffolding frames approximately 1.8 metres in height. The towers, which were preassembled, were manoeuvred into the designated location with a Pin Jib Crane operated by Arthur at the premises.
15 The scaffold platform was raised with the Pin Jib Crane and manoeuvred into position onto the top of the scaffold towers, but relied on weight and friction to hold it in place. The scaffold platform was not secured to the scaffold towers. No scaffold tower was installed to support the mid span of the scaffold platform.
16 The left hand end of the scaffold platform was supported by only one side of the scaffold tower.
Day of incident
17 At approximately 7.30am on 4 December 2002, Crouch, Reynolds, Ritchie and Arthur arrived at the premises. Will and Jones of The Defendant had also arrived at the premises to erect a permanent steel platform to the top of the reservoir wall, using the scaffold platform to do so. The reservoir wall was approximately 10 metres high. The scaffold platform was approximately 7.2 metres high.
18 Crouch, Reynolds and Will were on the scaffold platform. Crouch climbed back down to the ground. The permanent steel platform was raised by crane and placed in position at the top of the reservoir wall. Jones and Will then commenced drilling holes to locate the bolts which were to secure the permanent steel platform to secure it to the reservoir wall.
19 Crouch passed a ladder up for use between the scaffold platform and the reservoir wall.
20 Jones and Will then positioned the ladder on the scaffold platform with the top leaning against the reservoir wall, perpendicular to the left-hand steel davit arm of the permanent steel platform. The ladder was located approximately three metres in from the exposed right hand edge of the scaffold platform. The lower end of the ladder leant against the toe board of the scaffold platform. Jones and Will began taking turns drilling holes into the concrete reservoir wall for the placement of bolts using the ladder.
21 Jones was standing on the ladder using the vibrating percussion drill to make holes in the reservoir wall when he noticed movement in the scaffold platform. He scrambled up the ladder and grabbed the left davit arm of the permanent steel platform. Simultaneously, the scaffold platform slid towards the outer edge of the scaffold towers and tilted outwards from the reservoir. The force caused the scaffold platform to rotate, detaching it from the supporting scaffold towers.
22 Reynolds' immediate reaction was to grab the handrail of the scaffold platform as it fell. In doing so, the handrail sprung back towards him as it became detached from the platform. This caused Reynolds to be knocked unconscious as he fell approximately 7.2m to the ground. Reynolds landed at the base of the embankment surrounding the concrete reservoir.
23 Will fell approximately 6.2m to the ground onto the top of the embankment surrounding the concrete reservoir. He immediately looked up to see the 540kg scaffold platform falling towards his legs. Will's simultaneous reaction was to grab his knees and roll away from the platform. The 540kg scaffold platform struck the ground, arcing upwards. The scaffold platform then fell back towards the ground, crushing Will between the platform and the embankment surrounding the reservoir.
24 Will tried to lift the scaffold platform of himself as both shoulder blades were touching his chin. Will then yelled out 3 times, 'Get it off me!'. With the weight of the platform on top of him, Will could no longer breathe. Crouch, who had immediately arrived at the scene of the accident, arranged to lift the platform off Will by crane.
25 Reynolds received multiple injuries including fractures to his Transverse Process Bone, L1 to L4 to the right side of his back, a hip injury, lacerations to his left elbow, right shoulder and back of head, swelling of muscle tissue to left thigh and swelling to both knees.
26 Will received multiple injures including a fractured pelvis, multiple fractures to both shoulder blades (bilateral scapula fracture), a compression fracture to the 4th thoracic vertebra, a bilateral lung contusion and rhabdomyolysis. Will suffered internal bleeding for four days.
27 Jones did not fall as he grabbed the left davit arm of the permanent steel platform and pulled himself on to it.
Engineers' report
28 An engineering report by Michael Cheng for the WorkCover Authority dated 10 February 2004 noted the following:
28.1 There were no design drawings or calculations and no rated capacity provided for the scaffold platform.
28.2 This unusual modular scaffolding work platform was not designed, tested and certified as compliant with loading requirements of Australian Standard 1576.3 1995 Scaffolding Part 3 Prefabricated and Tube and Coupler Scaffolding. It did not have a duty classification or design registration with WorkCover.
28.3 The platform simply sat on the towers. There was no positive connection to prevent sliding or uplift of the platform.
28.4 The dimensions and support points for the platform resulted in the potential for the live loads (persons and materials) on the platform to be positioned such that the centre of gravity could move beyond the tipping line, resulting in uplift at the inner connection points. Without secured inner connection points, the platform would rotate about the outer support points and overturn if such a loading condition occurred.
29 Mr Cheng concluded that, without secured connection to the supporting towers, the work platform overturned about the tipping line owing to the distribution of live loads (persons and materials) at such positions which eventually caused its centre of gravity to shift beyond the tipping line.
30 An engineer's report prepared by Frank Spianaze & Associates for Mamfe dated 10 December 2002 (post the incident) identified the need for a third scaffold tower to support the mid span of the scaffold platform. The report also prescribed that the scaffold platforms have bearing onto both sides of the supporting scaffolding shore frames to either end.
31 An engineer's report prepared by Trevor A Jones & Associates for Mamfe dated 10 December 2002 (post the incident) prescribed that a hold down clamp be used to secure the scaffold platform to the supporting scaffolding short frames.
Investigation
32 Senior Inspector Michael Cameron attended upon the site on 4 December 2002 and undertook an inspection of the accident site. Senior Inspector Cameron reduced his observations to writing in the form of a "factual inspection".
33 On 5 December 2002 Inspector Cameron requested engineering assistance. In response, Michael Chang attended the scene and together with Colin Crouch, Kevin Plummer (Regional Contract Manager for Department of Public Works and Services) and Tom Blow (Project Manager for Department of Public Works and Services) witnessed a re-enactment of placing the work platform onto the scaffold towers arranged by Mr Colin Crouch.
34 Inspector Dianne Dunlop issued prohibition notice number 7-12896 on 4 December 2002 in relation to the immediate risk posed to safety by the scaffolding. The prohibition notice required Mamfe to provide and maintain safe and suitable scaffolding, with the damage to the scaffolding to be assessed and certified by a practising engineer before the scaffolding was returned to service.
Scaffolding
Further description
35 A Weigh Bridge Certificate dated 20 December 2004 confirmed that the net mass of the scaffold platform was 540kgs.
36 On 4 December 2002 the scaffold platform was supported by a single side of one of the supporting scaffold towers.
37 There was inadequate means of securing the scaffold platform to the scaffold towers.
38 The width of the scaffold platform was 900mm. This would allow a potential sideward movement of the steel platform of 320mm between the vertical lugs of the scaffolding shore frames.
39 The right-hand side scaffold tower leant outward from the reservoir wall at approximately 5 from the vertical.
Design registration and classification
40 Pursuant to Clauses 94, 107 and 136 of the Occupational Health and Safety Regulations 2001 the Defendant was required to ensure that the scaffolding had a current design registration number.
41 Additionally, those clauses required that the scaffolding comply with Australian Standard 1576.3:1995 (pre-fabricated scaffolding).
42 Section 4 of AS1576.3:1995 required that the scaffolding be tested and set out the testing methodology at Schedule E.
43 The scaffolding design was not, at any time, verified by a competent person as required under Clause 107 of the Regulations.
44 Whilst the unusual, uniquely designed scaffolding was designed by Mr Colin Crouch as an employee of Mamfe Pty Limited, the Defendant failed to take adequate steps to verify that the scaffolding complied with legislative requirements.
Australian Standard 4576:1995 Guidelines for Scaffolding
45 By operation of the Technical Guidance Code of Practice 2001, AS4576:1995 was incorporated without modification into the Technical Guidance Code of Practice.
46 In addition to the registrations failings referred to above, the scaffolding did not comply with provisions of AS4576. The compliance failures of the scaffolding concerned stability (Section 8.4), working platform (Section 8.7) and edge protection (Section 8.8).
Section 8.4 Stability
47 Section 8.4 of Australian Standard 4576 relevantly provides:
A scaffold must have the stability to prevent it from overturning. Stability may be achieved by tying the scaffold to a supporting structure…..
Section 8.7 working platform
48 The scaffolding was not at a height appropriate to perform work on installing the permanent steel platform to the reservoir wall. As a result of this, Jones and Will positioned a ladder on the platform as set out in paragraph 20 herein. This contravened section 8.7 of Australian Standard 4576:1995 as depicted in figure 8.7 'Unsafe Working Platforms'.
49 Use of the ladder on the platform was also contrary to the Defendant's Occupational Health and Safety Plan which relevantly stated:
Ladders will NOT be used where scaffold or other suitable working platforms are required.
The use of the ladder meant that any worker using the ladder was working above the platform railing without fall protection.
Section 8.8 Edge protection
50 Section 8.8 of Australian Standard 4576 relevantly provides:
Edge protection should be provided to the open sides and ends of any platform from which a person or object could fall 2 metres or more.
51 As set out in paragraph 12 herein there were no handrails at the end of the platform. The lack of edge protection was also contrary to the Defendant's occupational health and safety plan.
Safe work method statement
52 The Defendant failed to undertake and document a safe work method statement as required by clause 229 of the Regulation.
53 The Defendant prepared a work method statement in relation to the supply and installation of the metal work roof but did not address tasks associated with working at heights for the purpose of installing a permanent steel platform for the reservoir wall.
Amended Application for Order
54 It is alleged that on 4 December 2002, the Defendant, Coastal Fabrications Pty Limited (ACN 006 212 808), with its registered office located at 'William Nicholls' 109, Dalley Street, Mullumbimby, in the State of New South Wales, an employer, contravened section 8(1) of the Occupational Health and Safety Act 2000 at the Waterview Seelands Eatonsville Water Supply Site located at Hampton Road, South Grafton in the State of New South Wales ( premises ), in that it failed to ensure the health, safety and welfare at work of all its employees, in particular Bruce Will and Darren Jones. Particulars of the Defendant's contravention are as follows:
54.1 That the Defendant failed to adequately undertake and document a safe work method statement for tasks associated with working at heights for the purpose of installing a permanent steel platform for the reservoir wall;
54.2 That the Defendant failed to take adequate steps to verify the safety of the scaffolding utilised by its employees at the premises in that it:
(a) The Defendant failed to ensure the usual curved scaffolding met design registration requirements;
(b) The Defendant failed to ensure the scaffold platform was maintained at an appropriate height relevant to the height at which work was being undertaken;
(c) The Defendant failed to ensure adequate fencing of the exposed ends of the scaffold platform.
As a result of the said failures, Bruce Will and Darren Jones were exposed to risk of serious injury.
