(2) The defendant failed to undertake any risk assessment of the roofing work to be conducted by Vujinovic and Boric at the construction site.
The defendant pleaded guilty to the charge under s 9 of the Act.
6 The prosecutor tendered a statement of facts in which it was said:
The defendant's undertaking included the giving of OHS induction training and site specific training to some contractors in his designated capacity as trainer at the construction site. There is no documented evidence that employees or contractors to Drina Carpentry underwent site induction training prior to commencing work at the construction site.
On 7 September 2002 Boric commenced work at about 7.00am. Before lunch he was working on top of townhouse number 4 installing roof trustees and cutting eaves. After lunch, and shortly before 3.00pm, he had cut two roof rafters while positioned on the top of townhouse number 4 at a height of approximately 5.10 metres above the ground. As he prepared to cut a third roof rafter, he stood on the brick lintel, which was on top of a window. The brick lintel consisted of two rows of bricks, which gave way when Boric placed his weight on them, causing him to fall in excess of 5 metres to the ground.
As a result of the incident on 7 September, 2002 Boric received serious injuries including a broken elbow and hip and extensive bruising from his knee to his shoulder and neck. As of 10 April 2003 he had not returned to work, was undertaking therapy and walked with the aid of a walking stick.
At the time of (sic) accident Boric was not wearing a safety harness and lanyard or any other kind of safety device; nor was there any stable work platform such as scaffolding that may have prevented Boric from falling.
Prior to the accident the defendant failed to undertake any risk assessment of the roofing work to be conducted by Vujinovic and Boric at the construction site.
Prior to the accident there were no documented work method statements in place at the construction site.
On 7 September 2002 and shortly after the accident, Senior Inspector Ian Tyler, WorkCover Authority of NSW, attended the construction site. While there he met the defendant, who showed him the scene of the accident. Senior Inspector Tyler took a number of photographs and made a number of observations from the ground level of townhouse number 4, including the following observations:
(a) townhouse number 4 was a two-storey brick construction, part of a larger building with an incomplete timber framed roof;
(b) there was a concrete balcony at the base of the structure with an opening into the building;
(c) there were loose pieces of timber on the concrete balcony;
(d) at the top of the brickwork was an aluminium window with timber rafters overhanging the edge of external wall of various lengths, some with freshly cut ends;
(e) the townhouse next to townhouse number 4 appeared identical in construction but had a level of internal brick/block-work two courses above the top of the window frame, which was missing from townhouse number 4;
Senior Inspector Tyler then proceeded into townhouse number 4 and upstairs into an unfinished room known as the unsuited level 1. There he continued his investigations and made further observations:
(a) he measured, from the top of the ensuite window frame down to the concrete ground-floor balcony, a distance of 5.1 metres;
(b) he observed mortar on top of half bricks and loose steel "hoop iron" strapping on the timber top plate of the brickwork;
(c) he went to the level one balcony, situated adjacent to the rafter ends and the ensuite, and noticed that it had loose lengths of timber on the floor and no edge fall protection;
(d) he measured the cross-section area of a rafter end at 95mm x 45mm. Three rafters had been freshly cut at an angle perpendicular to the ground level. All rafter ends were of the same cross-sectional area;
(e) a slight circular indent was evident in the fresh cut of rafters two and three;
(f) rafter four immediately adjacent to the ensuite window had been marked with pencil parallel to its cut;
(g) on the other side of the rafter were three identical rafters protruding over the external wall all marked with pencil consistent with the cuts on the previous rafter ends;
(h) there was no evidence of fall protection such as scaffold or anchor points for safety lines on the roof or the structure;
(i) there was no evidence of tools, power or otherwise, evident at the scene of the accident.
Following the incident on 7 September 2004 (sic) Inspector Tyler issued Improvement Notice No. 246347 upon the defendant requiring him to ensure that a safe and suitable system of work to prevent risk of falls was implemented and that he provide and maintain a stable work platform from which to work safely.
Following the incident on 7 September 2004 (sic) the defendant arranged for external scaffolding to be erected at the site.
7 Annexed to the statement of facts was a Factual Inspection Report of Inspector Tyler dated 23 September 2002, 16 photographs taken by Inspector Tyler on 7 September 2002 and the Improvement Notice No. 246347.
8 The prosecutor also called evidence from Mr Vujinovic. That evidence went essentially to the discussions Mr Vujinovic had with the defendant and his father prior to and following Mr Boric's fall from the roof. A number of questions and answers were also allowed into evidence from a record of interview conducted by Inspector Connolly with Mr Vujinovic on 26 May 2003. It should be noted that Mr Vujinovic was prosecuted in relation to the incident on 7 September 2002 and fined an amount of $6,500: Inspector Connolly v Vujinovic trading as Drina Carpentry [2005] NSWIRComm 76. The prosecutor also called Robert Mayell, coordinator of the investigation construction team of the Occupational Health and Safety Division of the Work-Cover Authority.
9 Also in evidence were two affidavits, one by the defendant and one by Anthony David Clark, Daniel Clark's father and a partner in the family business. Both deponents were required for cross-examination.
Evidentiary issues
10 Three evidentiary issues that emerged in the proceedings were:
(1) Whether the defendant had a conversation with Mr Vujinovic prior to Mr Boric's fall as to how the work would be carried out near the en-suite dormer window and about the risks associated with stepping on the untied brick lintel.
(2) Whether it was impracticable to erect a stable work platform around the buildings under construction, such as scaffolding, rather than rely on a safety harness, scaffolding being considered the best level of protection prescribed by cl 56 of the Occupational Health and Safety Regulation 2001.
(3) Whether there was an obligation pursuant to cl 227 of the Occupational Health and Safety Regulation 2001 for the defendant to provide Mr Vujinovic with a written safe work method statement for the work to be carried out by Mr Vujinovic.
11 In considering the evidence in relation to the first issue, I have no doubt that a conversation took place between Mr Vujinovic and Mr Anthony Clark prior to Mr Boric's fall, whereby Mr Vujinovic was warned about the risks of working near the dormer window and about the instability of the brick lintel. I also consider Mr David Clark was present at the time of that conversation. What I am not convinced about, given the evidence of Mr Vujinovic who denied such a discussion and the lack of satisfactory corroboration by Mr Anthony Clark, is that Mr David Clark separately discussed with Mr Vujinovic the actual method by which the work was to be done. In my opinion, Mr David Clark merely relied on the warning given to Mr Vujinovic by his father and simply expected Mr Vujinovic to carry out the work in a safe manner.
12 In relation to the second issue, what I have difficulty understanding is why scaffolding was not in place from the outset given the evidence of Robert Mayell. Scaffolding would have provided a safe method of work for a number of the trades that would have been working on site including the work done by Mr Vujinovic and Mr Boric.
13 Mr Mayell's evidence was that at an early stage of the construction it would have been reasonably practicable to erect scaffolding from which rafters could have been tailed. However, as the construction progressed, it would not have been practicable to erect scaffolding in those areas where the dormer windows were located because, in the meantime, beneath those windows a lower roof covering was constructed. Mr Mayell said the first level of protection was a stable and securely fenced work platform such as scaffolding. If the installation of scaffolding was not reasonably practicable, secure perimeter screens, fencing, handrails or other forms of physical barriers that were capable of preventing the fall of a person should be put in place, and if that were not reasonably practicable the next level of protection was other forms of physical restraints (e.g., safety harnesses) that are capable of arresting the fall of a person from a height of more than 2 metres. Mr Mayell accepted that the second level of protection, handrails, etc., was not practicable.
14 After the accident the defendant did erect scaffolding but not in those areas where the dormer windows were located. After the accident a worker using a safety harness tailed the rafters adjacent to the dormer windows.
15 As to the third issue, my view is that the Regulation required the defendant to provide Mr Vujinovic with a written safe work method statement for the work to be carried out by Mr Vujinovic because the cost of the construction work at the defendant's place of work exceeded $250,000. Such a statement was not provided. Clause 227 applies to any place of work where construction work is undertaken. The application of the clause does not depend on the value of the work of a particular contractor.
