Allawah Road Realignment
ALLROADS were awarded the contract to relocate the existing Allawah Road to allow space for the future extension of Powerlinks’ Blackwall Switchyard.
The scope of works included four sections: Preliminaries, Earthworks, Roadworks and Stormwater Drainage and saw the construction of over 750m of a new two-lane road. In addition a visual screening barrier was constructed to block out views from adjacent residents.
Due to the alignment of the road being subject to flooding, there was a requirement for the elevation to be in line with Brisbane City Council flood level requirements. To ensure this requirement was met, ALLROADS installed a number of major stormwater culverts.
Works also required strict environmental controls given the sites proximity to the Brisbane River and location within a Koala Habitat and therefore required close community liaison to minimise any impact to surrounding residences.
Through efficient and effective planning and a “hands on” project management approach, the works were completed on budget, to the specifications of Powerlink, Council and DTMR and ahead of schedule; with the original 16 week program of works being completed in just 12 weeks.
