Project Duration

March 2018 - October 2019

Project scope

  • Demolition of existing aircraft apron including 20,000m² of asphalt/concrete
  • More than 70,000mÂł of bulk earthworks – cut and spoil and replacement
  • 23,000mÂł of concrete to be laid across a 65,000m² footprint
  • Installation of 1500m of drainage
  • Piling pads for new structures
  • Construction of an adjacent asphalt carpark, associated drainage and building pad
  • Installation of large fuel trap, flame trap and treatment filters


  • PFAS contaminated material to be disposed of
  • The potential impacts of dust and FOD to operational aircraft
  • The need to prioritise military operational needs at all times
  • Stringent specifications to achieve the required product standards
  • Identification of additional contaminants—such as asbestos and fuel lines—during the project
  • Security requirements of the base had the potential to impact access and deliveries
  • High ambient temperatures constrained concrete pour times


  • Developed and implemented a detailed methodology to ensure deep sewer line was constructed safely
  • Collaborative relationship established with Principal’s Representative enabled implementation of several time-saving initiatives
  • We worked closely with Boral to achieve a constant mix throughout
  • Undertook concrete pours at night to reduce risk of premature setting due to high ambient temperature
  • Stage #1 was completed six weeks ahead of schedule
  • Stage #2 was completed two months ahead of schedule
  • All asbestos and contaminated material safely removed from site and disposed of in accordance with regulations
