  • Challenge

    The 500mm main runs through a mix of established brownfield areas and open greenfield ground, so the crew had to switch methods along the route while keeping the work safe and on programme.

  • Approach

    Benang self-performed the pipeline build, clearing and grubbing, establishing the right of way, then stringing, welding, and installing the 500mm main through both ground types before reinstating the corridor.

  • Outcome

    The project is running with zero lost time injuries and zero environmental incidents, and Aboriginal participation of up to 30 per cent.
