The Edinburgh Design Team (EDT), with GHD Woodhead as lead consultant, was awarded the AUD650 million Hardened Network Army Edinburgh Defence Precinct Project (HNA EDP Project) in December 2006. The HNA EDP Project is the largest design contract ever let by Defence, encompassing the redevelopment of a large part of the RAAF Base at Edinburgh, and includes the delivery of 56 individual buildings providing working accommodation, administration support, training facilities, messing, base infrastructure, maintenance and storage facilities for the 7th Battalion Royal Australian Regiment (7RAR) to move from Darwin to the Edinburgh Defence Precinct in South Australia.

The project involved construction of facilities for a mechanised battalion group and complete redevelopment of common user facilities at Edinburgh. The works included working accommodation, training facilities, urban operations training facilities, a driver training area, vehicle refuelling and wash points, plus common user facilities including health, mess, physical fitness, community and commercial facilities. Extensive site-wide electrical, communications and civil infrastructure works were also included.

The project scope and program required the formation of a significant design team involving a range of specialist consultants who were located in a project office during the critical development phase. The design team worked in collaboration with multiple stakeholders in a carefully managed consultation framework.
