CLIENT: Main Roads WA
TIMEFRAME: January 2011 – February 2013
VALUE: AUD$110 million
Delivered on time and within budget, the Dampier Highway Duplication was a design and construct project completed in remote regional Western Australia by the HWA (Highway/Downer Works/Albem Operations) Joint Venture, in partnership with Main Roads WA.
The project involved the construction of seven kilometres of new dual carriageway between the Karratha town site and airport, including the construction of a new bridge structure and refurbishment of an existing bridge over Seven Mile Creek. Optional works, added at a later date, extended the road an additional six kilometres from the airport to the Burrup Road intersection.
The project included extensive traffic management in a high speed area with a high proportion of vehicles and included the first slip-based, cyclone rated, high speed road light pole in Western Australia.
A well managed stakeholder engagement strategy included extensive and proactive communications with major miners, gas producers and mining service companies in an expanding industrial and residential precinct adjacent to the work site.
Significantly, this project included the construction of 20,000m2 of high strength, hand placed concrete pavements. This was a first for a Main Roads WA project. The new technology was developed in collaboration with Main Roads using NSW expertise.
Blasting management around the Dampier to Bunbury gas main
The efficient management, protection and relocation and of services was also a significant feature of this complex and high profile project, which included protecting the high pressure Dampier to Bunbury gas main during detailed blasting.
