Darlington Pipeline Upgrade

The Darlington Pipeline Upgrade Project is the next step in the North-South Corridor project and involves the upgrade of the 2.3 km section of Main South Road between the Southern Expressway and Ayliffes Road.

The upgrade and realignment of existing infrastructure is required to allow for the South Australian Government’s Department of Planning, Transport and Infrastructure (DPTI) upgrade to South Road.

The scope of works for this project includes the design and construction of new trunk water and sewer mains, and various small diameter mains between the Southern Expressway (M2) and Ayliffes Road, and between the Shepherds Hill Road / Ayliffes Road and Crystal Avenue intersections. Works include inline valves, various offtake connections and pipelines, and integration with the existing network.

The project faces a number of challenges including a compressed construction time and maintenance of peak traffic flows whilst constructing a 4m x 4m deep trench within the road corridor.

To ensure these challenges are achieved, the York Civil team has developed a number of initiatives which include:

  • an alternative link-in strategy that allows greater flexibility in construction time
  • an engineered road plate/bridge system which enables reinstatement of full traffic movements at the completion of each shift, and
  • alternative alignment proposals and methodologies which alleviate, and in some cases eliminate, some pre-determined restrictions on the project.

The project will require sensitive community and stakeholder management, along with complex traffic management strategies to ensure minimal impact on the community and commuters.
