What We Have Achieved

Kooragang Arrival Road - Stage 2 Civil Works

March 2016 - November 2016

Client Information


  • Duration: March 2016 - November 2016
  • Value: $7.2M
  • Location: Kooragang Island

Scope of Work

  • Construction of approximately 900m of embankment widening to accommodate an extension to the Arrival Roads on Kooragang Island
  • Approx 5km of access along existing dilapidated roads and new temporary access roads through the wetland within the project footprint
  • Foundation investigations and preparation for the Ecoflex retaining wall. Foundation material was a mix of cemented slag, marine clay and sand generally below groundwater level
  • Signalling route and infrastructure constructed concurrently with the embankment rebuild
  • Excavation, handling and disposal of 8000T of potentially asbestos impacted soils from the existing embankment. Due to the confined area, innovative handling and validation methods were used in the works to mantain WHS requirements and production goals
  • Ecoflex retaining wall used for the embankment widening undertaken by a subcontractor under our management
  • Successful rehabilitation of disturbed areas
  • Geotechnical instrumentation and monitoring of ground movements as a result of the works to ensure no impact to the adjacent Jemena Gas Pipeline

Significant Achievements

  • All works constructed within an environmentally sensitive environment with Ramsar listed wetlands and endangered fauna habitats immediately adjacent to the works and along the access into site
  • Access along the worksite limited to a maximum width of 3m
  • Development and refining of the original works design undertaken co-operatively with ARTC and their designers to minimise project delays
  • Works completed ahead of schedule
  • All works completed adjacent to the live Arrival/Departure Roads for the Kooragang Coal Terminal with no productivity impacts to trains
  • Working within a highly sensitive environment (both environmentally and industrially sensitive) with negligible impacts from our works
  • Project was awarded the inaugural ARTC Safety Award for our innovative management of potentially asbestos contaminated soils onsite
