4 An agreed statement of facts was tendered. Relevantly, the statement provided the following information:
8 At all material times the defendant employed the following persons:
(a) Ron Lucas as a site foreman ("Mr Lucas");
(b) Andrew Payne as a sub foreman ("Mr Payne"); and
(c) Carmello Licciardello as a project manager ("Mr Licciardello").
9 At all material times prior to and including 3 October 2000, the defendant had subcontracted with Abbey Precast Concrete Australia Pty Limited (ACN 080 026 115) ("Abbey"), now known as Danmark Precast Pty Ltd to supply all labour, materials, plant and equipment to complete the installation of the precast concrete wall panels and associated works at the site.
10 At all material times prior to and including 3 October 2000, Abbey had a verbal subcontract with Combined Crane & Rigging Pty Ltd ("the sub-subcontractor") to install tilt-up concrete panels at the site.
11 At all material times, the sub-subcontractor was responsible for the erection and installation of panels at the site.
12 The defendant prepared a "Site Hazard Schedule" in relation to the site on 29 January 1998. The Schedule amongst other things identified the requirements to obtain a written Work Method Statement from the crane crew and tilt panel erector.
13 The defendant prepared a "Project Safety Plan No.74" for the site dated 20 March 2000. The Safety Plan included the following aspects:
(a) Clause 2.2 - Project Manager's Responsibilities;
(b) Clause 2.2 - Site Foreman's Responsibilities;
(c) Clause 8.1 - General Site Safety Inspections;
(d) Clause 11.3 - Work Method Statements;
(e) Clause 12.1 - Site Induction.
14 By facsimile dated 19 June 2000, Abbey provided a copy of the sub-subcontractor's written Work Method Statement dated 19 June 2000 to the defendant in relation to the installation of precast concrete panel erection for Abbey at the site.
The Work Method Statement included the following provisions:
"8.6 Safe access/egress is to be maintained to work areas at all times by the main contractor.
ADDENDUM
1. Place panel at set position with the crane and attach support props to ferrules cast into the panel at approximately 1-5 points plum panel drill M20 hole and fix bottom of prop with WA20-120 Reid Wedge Anchor. Bolt tighten and repeat for second prop. All panels must have two props per panel."
15 At all material times the sub-subcontractor was an employer.
16 At all material times, the sub-subcontractor employed:
(a) Arthur Didovich, a director.
(b) Ian Lee ("Mr Lee"), the crane operator
(c) Mario Kalatinic ("Mr Katalinic"), labourer
(d) Robert Davies ("Mr Davies").
(e) Mr William Latimer ("Mr Latimer").
17 At some time between 29 September and 3 October 2000 the sub-subcontractor had erected panels at the site, including but not limited to panel numbered 243.
18 On 29 September 2000, Mr Payne met with the Mr Didovich at the site to discuss the procedure of what would take place on 3 October 2000 ("the 29 September meeting").
19 During the course of the 29 September meeting, Mr Didovich advised Mr Payne that for the purpose of crane access to install the concrete panels for an internal wall, two setup props that were attached to panel 243, would need to be moved. Mr Didovich stated that the proposed work method was to install two additional props so as to ensure that there were two props in place at all times. It was further discussed and agreed that as an additional precaution fishplates would be welded to panel 243 and each adjoining panel prior to the removal of the props to give further stability to panel 243. Mr Payne stated that he would confirm with Abbey for a welder to be present on site on 3 October 2000 to undertake the welding work, in particular welding the fishplates to panel number 243 before the props were adjusted.
20 Following the meeting on 29 September 2000, Mr Payne telephoned Mr Paul Cattabriga of Abbey to arrange for a welder to be present at the site on the morning of 3 October 2000. In the event there was no welder in attendance on 3 October 2000.
21 On 3 October 2000 the crane was set up on a suspended slab consisting of hardwood timbers laid down on the first floor of the building under construction. Its function is to distribute the load of the crane. The size of the suspended slab was approximately 8ft by 8ft.
22 At all material times each panel was placed into position using the crane. Employees of the sub-subcontractor directed each panel into position. Each panel was numbered. Once a panel was installed the employees of the sub-subcontractor put props into position to secure each panel in place. The props were put on with the assistance of a cherry picker. The props were attached to the ferrule which forms part of the panel and the other end of the props were bolted to the floor using Dyna bolts. Each prop was secured to the ferrule with a pin which would be secured with a bent over nail or piece of wire to stop the prop from coming out. The first prop of each panel was used to plumb the panel before the second one was fitted or locked off.
23 At all material times on 3 October 2000, panel 243 was located on the north western side of the site on level 2 at the end of a row of four other tilt up panels. The panel formed part of the north wall and had two props supporting it. The props were secured with pins and Dyna bolts.
24 At all material times on 3 October the panel had a blue label on its base with identification number 243.
25 At all material times the panel weighed approximately eight (8) tonnes and measured between approximately 6 to 8 metres long by approximately 2 metres wide
26 The crane being used by Mr Lee on 3 October 2000 was an orange Cerdano 50 tonne mobile crane ("the crane") which was being used by the company to install the panels. The crane was facing the opposite direction to panel 243.
27 Mr Lee spoke to Mr Lucas, the foreman employed by St Hilliers to arrange for the movement of the propping under the suspended slab whilst he and the other employees of the sub-subcontractor had lunch. The crane was to be moved out, turned around and driven into position to begin installing the internal wall which was to run perpendicular to the north wall.
28 On 3 October 2000 at approximately 1.15pm after some consultation with Messrs Lee, Latimer and Davies, Mr Katalinic removed two props from the panel to allow access for the nose of the crane. Mr Katalinic removed the pin from the first prop then walked away to get the rattle gun to undo the dyna bolt. Instead of undoing the bolts on the first prop Mr Katalinic loosened the dyna bolts on the second prop. Shortly after removing this Dyna bolt the panel fell onto the roof of factory unit 4 at 80 Reserve Road, Artarmon which was located next door to the site.
29 When Mr Katalinic commenced removing the props from the panel,
(i) (sic) had not been secured by other means; specifically the additional props had not been installed and the panel had not been welded to the adjacent panels using fish plates; and
(ii) it had not been inspected to ensure that pins and Dyna bolts were secure.
30 From an inspection of the prop connections after the panel collapsed it appeared that there was no pin in the second prop.
31 As a consequence of the panel collapsing, damage was occasioned to units 1, 2, 3, 4, 5 and 6 located at 80 Reserve Road, Artarmon. The estimated cost of the damage was over $1,000,000.
32 At the time of the incident there were members of the public present in the vicinity of unit 4, 80 Reserve Road, Artarmon. Mr Peter Rolls, Mr Reg Rolls and Mr Clive Hores were present inspecting a motor vehicle.
33 At all material times on 3 October 2000, the sub-subcontractor failed to follow its own Work Method Statement in that a minimum number of two props should have been in place to hold the panel.
34 At all material times on 3 October 2000, the defendant and the sub-subcontractor failed to ensure that the prop was secured in place by a fishplate before removing its props.
35 At all material times the defendant and the sub-subcontractor failed to inform its employees of arrangements that had been made for the securing of the panel by alternative means before the props on panel 243 were moved.
36 At all material times there was no or any adequate record kept in the form of a site diary or otherwise of arrangements that had been made between Mr Payne and Mr Didovich as to how the panel was to be secured prior to the removal of props to allow crane access.
37 At all material times including 3 October 2000 the defendant had no documented procedure for checking the security of the pins and Dyna bolts that secured props to the panels, and specifically panel 243.
