The Set-Up
21. In early January 2003, Ishak contacted Jeff Chehine-Nehmetallah (Chehine), an employee of C & A Chehine, the partnership usually retained by the defendant for concreting works on Dewcape's sites. It being early January, C & A Chehine were on holidays, however Chehine agreed to assist with the concrete works personally.
22. As Dewcape required the services of a concrete boom pump to pour concrete footings at the site, Chehine contacted Mr Pump on 7 January 2003 and arranged for Mr Pump to provide a concrete placing boom and crew at the site on 8 January 2003. Chehine ascertained from Mr Pump the minimum distances required to set up the outriggers (stabilisers) of the concrete placing boom pump. Mr Pump the minimum width of 6 - 7 metres was required. Ishak arranged an area within the boundaries of the premises, which he believed was suitable for the set up of the concrete placing boom, which had 7 metres of clearance.
23. On 8 January 2003 Challita was assigned by Mr Pump to drive and operate the concrete placing boom for the purpose of placing concrete at various construction sites, including the subject site. Budwee was assigned by Pump to assist Mr Challita.
24. After completing work at another site, Challita drove the concrete placing truck to the subject site, together with Budwee, arriving at the site between about 1.00 pm and 1.30pm that afternoon.
25. On arriving at the site, Challita parked the concrete placing boom at the front of the site, alighted from the vehicle and had a discussion with Ishak about where to set up the concrete placing boom for the pour.
26. Ishak nominated an area within the confines of the site as the area in which the concrete placing boom was to be set up for the purposes of the pour. But, Challita rejected that area as unsuitable because he could not adequately deploy the stabilisers and it was area that had been filled. Although the area had been filled, it had been compacted.
27. As an alternative, Challita nominated the driveway of the site, extending out past the front boundary of the premises as a suitable area in which to set up the concrete placing boom. This was subject only to the observation that he could not deploy the boom from that position without damaging a tree located on the site adjacent to the front boundary of the premises.
28. It appears that the boom could not be deployed in the opposite direction (that is away from the tree) because of the proximity of a telegraph pole.
29. Ishak and Challita further discussed the set-up of the concrete placing boom pump. Ishak requested a further three times that Challita set up the concrete placing boom pump at the initially nominated site within the boundaries of the premises and remote from the overhead wires referred to above. However, Challita declined.
30. When interviewed after the event, Ishak stated that he and Challita looked at the hazards in the driveway area and that Challita told him that he would have enough "clearance" to clear the powerlines and tree. Ishak also stated that he then left it up to Challita to determine the area in which the concrete placing boom pump was to be set up for the pour and Challita again nominated the driveway area.
31. Ishak proceeded to made a telephone call to Teh to discuss the possibility of damage to the tree. Following the telephone discussion Ishak agreed to Challita setting up the concrete placing boom in the driveway of the site.
32. Challita then positioned the concrete placing boom in the driveway with its rear extending beyond the front boundary of the site across the footpath to the gutter line. After positioning the concrete placing boom 'in the driveway' of the site, Challita and Budwee deployed the stabilisers and prepared to deploy the concrete placing boom. At this stage, Ishak proceed to the footings and completed the steel fixing required for the pour. By the time he turned around the boom was set up.
33. At no time did Challita consult the SWMS supplied by his employers, a copy of which was located in the driver's cabin of the concrete placing boom.
34. At no time did Ishak require Challita to provide him with a copy of the SWMS.
35. At no time did Ishak require Challita to conduct an adequate risk assessment with respect to the set-up and/or operation of the concrete placing boom pump in the driveway of the premises, nor did Ishak perform any adequate form of risk assessment with respect to the placement, set-up and/or operation of the concrete placing boom pump in the driveway of the premises. Any adequate of risk assessment would have disclosed that the driveway was an inappropriate location for the placement, set-up and operation of the concrete placing boom pump because of the proximity of the overhead electrical cables.
36. A combination of Low Voltage, Street Lighting and High Voltage powerlines ("mains") were slung immediately adjacent to the front boundary of the premises. The Low Voltage mains (LV mains) were slung at height of 6.6 metres above the footpath. The Street Lighting mains (SL mains) were slung at 7.2 metres above the footpath. The High Voltage mains (HV mains) were slung at 9.5 metres above the footpath.
37. Each of these sets of wires passed directly over the rear of the concrete placing boom once it was in place and set up in the driveway of the site ready for the boom to be deployed.
38. As the concrete placing boom was 3950mm high when located at rest, the boom was already within the safe working distances referred to above by approximately 350mm before Challita commenced deployment of the boom.
39. Once the boom had been deployed and was fully extended, and the concrete was being poured, the boom was well outside the safe working distance from the power lines.
40. Once the concrete pumping boom was ready for deployment, Challita connected the remote control and then stood away from the machine with the deceased. Challita progressively unfolded the boom and slewed it so that it was facing towards the rear of the site. During this operation Challita encountered problems with the tree that was located in the northwest corner of the site adjacent to the driveway and Stanley Street.
41. Challita then advised Ishak that they were ready to pour the concrete. Approximately 20 minutes later the concrete commenced arriving and they commenced to pump the first truckload of concrete. The first 30 cubic meters was delivered in various concrete trucks and was pumped within an hour to an hour and a half. Then Ishak continued to order the concrete a truck load at a time.
42. In total there were 50 to 60 cubic metres of concrete to be poured which equates to approximately 10 full truckloads of concrete.
43. Towards the end of the concrete pour a storm passed through the area consisting of rain, light hail and strong wind conditions. Attached marked 'D' is a copy of a Certified Extract from the Bureau of Meteorology dated 3 June 2005 for that day.
44. Also towards the end of the concrete pour, it was decided that the remaining section of the footings could be poured from the chute of the final concrete delivery truck, as there were only 1.5m3 of concrete left to be poured. Ishak informed Chaillta that he could pack up and leave.
45. Challita enquired of Ishak where he could blow the concrete out of the boom and Ishak said in the footings. Ishak then left the worksite to go to the shops. A sponge was then placed into the lines and the lines were then blown out into the footings. After the initial procedure, Challita gave Budwee the sponge that came out of the line to clean so they could then "blow the lines" once again.
46. Challita then got up into the cabin of the truck and pressed the accelerator to build up the air so he could engage the power take off (PTO) and retract the boom.
47. At this time, Chehine and Budwee were standing on the side at the rear of the concrete placing boom. Chehine was hosing his boots and Budwee was flushing water through lines associated with the concrete placing boom.
48. Challita walked around, climbed up to the area where the remote control for the boom connects to the vehicle, operated the remote so as commence to folding the boom towards its closed position and also commenced to slew the boom towards the tree adjacent to the front boundary of the site. As Challita slewed the boom towards and into the foliage of the tree, Challita saw the power lines blowing back and forth also within the foliage of the tree. Challita says that at this point he became concerned about the boom coming too close to the powerlines and that he called out to Budwee for his assistance. There was no answer.
49. Challita then turned to his right and, out of the corner of his eye, saw Budwee lying on the ground.
50. At about the time that Challita called out to Budwee, Chehine was walking to rear of the truck when he heard a 'cracking snap noise'. Chehine then turned and also saw Budwee lying on the ground. Shortly, thereafter, Ishak returned to the work site and became aware of the incident.
51. On observing the location of the boom in comparison to the overhead powerlines referred to above at or about the time of the incident, Chehine, Ishak and a number of independent witnesses all describe the boom with the second stage still partially deployed, well within the safe working distance of 3 metres from the overhead wires referred to above.
52. A post mortem conducted by Dr Johan Duflou of the Department of Forensic Medicine on 10 January 2003 revealed evidence of injuries to Budwee's right hand and Budwee's right foot consistent with electrical burns. Duflou concluded that the cause of death was electrocution.
53. An investigation was carried out by Energy Australia which concluded, in all the circumstances, the most likely explanation for the electrocution was a contact with, or a flashover from, the 11kV, or HV, mains, running adjacent to the front boundary of the site as the boom was being slewed through the foliage and/or branches of the tree referred to above. Attached and marked 'E' and 'F' respectively, are an Investigation Report prepared by Keith Newland of Energy Australia, undated and a Fatal Shock Investigation Report dated January 2003.
54. On 8 January 2003, officers from the New South Wales Police -Forensic Services Group, Chatswood Crime Scene Section attended the site and took a number of photographs. Copies of those photographs are attached and marked 'G'.
55. On 9 January 2003, Inspector John Gjaltema attended the site and made observations contained in an Incident Factual Report dated 15 January 2003 which is attached and marked 'H'.
56. On 9 January 2003,whilst at the site Inspector Gjaltema took a number of photographs which are attached and marked 'I'.
57. No proper precautions were taken by Dewcape and Ishak with respect to setting up and/or deployment of the concrete placing boom within the vicinity of the overhead powerlines.
58. No precautions were taken by Dewcape and Ishak with respect to operating the concrete placing boom in windy conditions and in particular the operation of the boom in proximity to overhead powerlines in those conditions.
59. Dewcape has no prior criminal convictions.
60. Mr Ishak has no prior criminal convictions.
Relevant Principles
10 In considering penalty, I take guidance from the reasoning of the High Court in Markarian v R (2005) 215 ALR 213 and their Honours' view that the task of sentencing must acknowledge the effect of the applicable legislative provisions (in this case s8(2) and s26(1) of the Occupational Health and Safety Act 2000 with ss21A, 22, 23, 34 of the Crimes (Sentencing Procedure) Act 1999). The court, using the "instinctive synthesis" approach, would include an assessment of the objective and individual subjective factors, with the appropriate weight given to each factor. The court could (but not should) give a degree of deduction in penalty to some element in the consideration, in such circumstances as where it better serves the interests of transparency, which element should be narrowly confined (for example, the utilitarian value of the plea).
