Onslow Marine Support Base
WGA undertook detailed design of a new marine support base at Onslow. The project included maritime structures, civil works (pavement and stormwater), geotechnical advice for optimisation of the wharf retaining
wall structure, temporary works design for pile driving frames, concrete formwork systems and adjacent wharf capacity assessments for lifting the dredge barge (approx. 80t lift) as well as an upgrade and extension of the Harbour Approach Channel.
