Overview: The St Peters Interchange project was part of the early works for WestConnex, Australia’s largest road project, linking Sydney’s west and south-west with the city, airport and port in a 33km continuous motorway. The project involved the strategic removal of approximately 140,000 tonnes of asbestos contaminated material, removal of restricted waste, 110,000 tonnes of general solid waste, reusable sands, plastics, and timber waste.

During the project major land slip stabilisation works were conducted to the Princess Highway boundary preventing potential damage to adjoining properties.

  • Preparation and implementation of a site management plan
  • Clean up of asbestos-contaminated material, known as Stockpile 21
