3 The following charge under s15(1) of the Act is brought against the Western Australian company by whom the injured employee was employed:
VIBRO-PILE (W.A.) PTY. LTD. (ACN 009 106 585) . . . ("the Defendant"), being an employer at a construction site located at 27 Henderson Road, Turrella in the State of New South Wales ("the site") DID FAIL, on 14 August 2000, contrary to Section 15(1) of the Occupational Health and Safety Act 1983 (NSW) to ensure the health, safety and welfare at work of all of the Defendant's employees and, in particular, Mr Russell William Collyer in that:-
(a) It failed to provide such information, instruction, training and supervision to Mr Collyer in regards to the process of driving sheet piles by the use of an unsupported dummy sheet pile called a dolly ("the dolly") at the site.
(b) It failed to ensure that the work carried out by Mr Collyer in relation to the driving of sheet piles involved a system of work which was safe and without risk to health to ensure that the dolly was sufficiently attached to the hammer of the crane to prevent it from falling and causing injury to Mr Collyer.
4 Relevant to the charge under s15(1) the following facts are agreed:
2. The Defendant Vibro-pile (WA) Pty Ltd (ACN 009 106 585) is a company duly incorporated in Western Australia with a registered office located at 1 Steele Court, Mentone in the State of Victoria, was at all material times an employer in the state of New South Wales being an employer at a construction site located at 27 Henderson Road, Turrella in the State of New South Wales ("the site").
3. At all material times Baulderstone Hornibrook Engineering Pty Limited and Bilfinger + Berger had formed a joint venture known as the BHBB M5 East Joint Venture ("BHBB") in relation to the construction of the M5 East Motorway.
4. At all material times Vibro-pile (Aust.) Pty. Ltd. (ACN 006 103 126) sub-contracted to BHBB to carry out the steel piling works at a construction site located at 27 Henderson Road, Turrella in the State of New South Wales ("the site") which involved the installation of 204 pre-fabricated Arbed type AZ 18 sheet piles ("the undertaking").
5. At all material times the Defendant was a labour hire company and provided labour to Vibro-pile (Aust.) Pty. Ltd. at various sites including the said site.
6. At all material times the Defendant was an employer in the State of New South Wales.
7. At all material times the site was the Defendant's place of work.
8. At all material times the Defendant employed
(1) Mr Russell William Collyer, aged 35 years, as a labourer to carry out work on behalf of Vibro-pile (Aust.) Pty. Ltd. under the direct instruction of Mr James Morris, a Contract Supervisor, at the said site.
(2) Jason Dandy as a leading hand labourer at the said site
(3) Brian Smith as a crane operator at the said site
9. As part of the sub-contract between Vibro-pile (Aust.) Pty. Ltd. and BHBB, Vibro-pile (Aust.) Pty. Ltd. was carrying out the installation of 204 pre-fabricated arbed type AZ 18 plus 1.0 sheet piles. The sheet piles were installed using a crawler crane utilising a PTC Vibrofonceur 40-a-2 vibrator and a Hydraquip hydraulic hammer. The procedure for vibrated and driven sheet pile put in place by Vibro-pile (Aust.) Pty. Ltd. required that " where piles finish at or below ground level, the service crane will be fitted with a short set of leaders and the hammer is placed in the leaders. A dolly (dummy sheet pile, approximately 3 metres long) is used to drive sheets down to final level".
10. The process required the dolly to be placed, by the use of a crane, on the top of the individual sheet pile. The dogman would check the position of the dolly and then unhook the dolly from the auxiliary line of the crane. Using the hammer attached to the crane, the sheet pile would be driven down to the required level. The hammer would then be lifted off the top of the dolly and then the auxiliary line would then be re-attached to the dolly so the dolly could be removed from the sheet pile that had just been driven. The process would then start again, with the dolly being placed onto the next sheet pile to be driven.
11. The system used did not require the dolly to be attached to the hammer. The dolly weighed approximately 1.38 tonne.
12. On 14 August 2000, Mr Collyer, Mr Dandy and Mr Smith were carrying out the installation of the pre-fabricated sheet piles at the site, under the supervision of Mr Morris.
13. Mr Smith was operating the crane at the site, with Mr Dandy acting in the position of dogman, checking the positioning of the top of each sheet pile. The workers had finished driving sheet pile number 194 at the site and took the dolly off sheet pile number 194 and tried to fit it onto the top of sheet pile number 193. The dolly would not fit so Mr Morris was called over by Mr Dandy to assist. Under the instruction of Mr Morris, Mr Dandy cut the top of sheet pile number 193.
14. Approximately two weeks earlier, due to difficulties attaching the dolly to sheet piles, Mr Morris had given instructions for the trimming of the teeth of the dolly to allow easier placement and removal.
15. Once sheet pile number 193 had been trimmed, Mr Dandy using a ladder, unhooked the dolly from the auxiliary line of the crane which had been used to lift the dolly. After Mr Dandy had come down from the ladder, Mr Collyer took the ladder to move it out of the way. Suddenly the dolly started moving. Mr Dandy called out to Mr Collyer to get out of the way but Mr Collyer was unable to move out of the way in time. The dolly fell down off the top of sheet pile No. 193 and struck Mr Collyer.
16. Mr Collyer had received general occupational health and safety induction training upon commencement at the site. He also received on the job training with respect to the system used for driving sheet piles and with respect to some safety precautions in that regard.
17. In the subject accident, Mr Collyer suffered a fractured right eye socket, a broken back, a dislocated left hip, multiple fractures to his lower right leg, a cracked sternum, three fractures to the right ribs, a broken right foot, lung contusions and facial lacerations.
18. The Job Safety Analysis for the specific task of driving sheet piles made no reference to the necessity of having the dolly permanently chained to the hammer to ensure that it would be safely in place.
19. Since the accident, Vibro-pile (Aust.) Pty. Ltd. has issued an amended procedure for vibrated and driven sheet piles which requires that the dolly be permanently chained to the hammer.
