The Woolgoolga contract was a highway upgrade for the RMS in consortium with Lang O’Rourke, who were the Principle Contractor. The works was broken into various conflicts over a section of 55km of the Pacific Highway from Woolgoolga to Ballina.

The NJ Construction section was from Yamba to Broadwater, and consisted of seven conflicts.

There were two sections of 66kV line that required upgrade. The first at Yamba Road required that the overhead power line be relocated to underground power supply, due to the new bridge to be built crossing the Grafton River needed to be significantly higher than the existing bridge.

Under boring was required to install an envelope pipe with trefoil cable conduits to be installed for each phase, as well as a spare for future. The other five conflicts were on the 11kV distribution feeders, which were also significant.

The documentation requirement from the RMS was significant, and took a long time to get mobilised to the site. The challenge was met by NJ Construction have a strong management team committed to setting up and delivering this project at the level required by the RMS.

Traffic control was also used on a regular basis due to the work being located on the existing Pacific Highway. This involved NJ Construction building a strong relationship with traffic control to aid in the completion of proposed works without traffic delays or disruption to local communities.

Once site had been established, and the first rounds of audits had been performed on NJ Construction, which NJ Construction passed well, the remainder of the highway upgrade works progressed according to program and to plan, with nil safety incidents.
