Australian Marine Complex Common User Facility Wharf Expansion

Tetra Tech’s High Performance Buildings Group was appointed as services engineer and project manager for the expansion of the Australian Marine Complex’s (AMC) Common User Facility (CUF) to allow for naval ship refits.


  • Size: 40 hectares (99 acres)
  • Construction Cost: AUD$180 million (USD$122 million)
  • Client/Owner: AMC Management and Landcorp
  • Architect: Clark & Standfield
  • Contractor: Transfield McMahon joint venture / Multiplex
  • Completion Date: 2010


Located 23 kilometers (14 miles) south of Perth, the AMC is a world-class center for the repair, maintenance, and construction of naval and commercial vessels, as well as for infrastructure for the fabrication and assembly of offshore oil and gas modules. It is home to the largest marine industry in Australia and is the base for over 150 businesses.

The CUF is recognized as a center of excellence for shipbuilding and repair and maintenance work for commercial and Royal Australian Navy vessels. The facilities available at the CUF have enabled companies to secure and deliver fabrication and assembly projects for large infrastructure modules used in mining and oil and gas projects locally, nationally, and internationally.

The work Tetra Tech undertook at this 40-hectare (99-acre) marine fabrication and assembly facility required staged implementation of new power, water, and fire systems. As work was undertaken at a "live" facility, completing the project in a timely manner was of ultimate importance. This fast-track project required innovative approaches in design and contracting to ensure that commitments were met. Innovations included temporarily housing a power conversion plant in a sea container.

Tetra Tech also provided design and documentation of all services associated with the wharf expansion. We provided electrical services, high- and low-voltage power distribution, power conversion, lighting, mechanical services, plant buildings, water and sewage systems, fire systems, communications, and security systems.

Projects undertaken by Tetra Tech as part of this AUD$180-million (USD$122-million) upgrade include:

  • Project management and design of the power, fire, and water distribution systems
  • Master planning for multiphase upgrades
  • 60-Hertz power conversion plant units
  • 22-kilovolt substations and distribution
  • Saltwater cooling and fire protection pumping systems
  • Sewer drainage systems
  • Potable water distribution
