This very unique design-and-construct project comprised the demolition of existing wharf facilities and the concurrent construction of five new commuter ferry wharves across Sydney Harbour at Cremorne Point, Balmain East, Pyrmont Bay, Sydney Olympic Park and Meadowbank.ÌýÌýDriven by ageing infrastructure and insufficient disability standards for accessible public transport, the builder developed solutions that significantly improved maritime safety, commuter safety and customer experience.ÌýÌýEach wharf features a pontoon and 18m-long gangway, sized and oriented to accommodate site-specific maritime conditions.ÌýÌýThe design places commuters close to the ferry, minimising embarking and disembarking time and providing waiting areas with balanced protection from the elements.ÌýÌýThe building process required three distinct stages:-ÌýÌý•ÌýÌý ÌýProcurement and preparation of long lead items.Ìý Ìý•ÌýÌý ÌýOff-site works on a separate site on Glebe Island.Ìý Ìý•ÌýÌý ÌýOn-site works of pile installation, concrete bridge works and pontoon and gangway installations.ÌýÌýThere was an emphasis on pre-fabrication of components including pre-cast concrete headstocks, pre-cast deck planks and pre-fabrication of the entire gangway ramp and pre-fabrication of the pontoon and fit off at an off-site facility prior to the elements being floated and installed onsite and final fit off being carried out.ÌýÌýThe builder addressed many construction challenges which required traditional construction processes, procedures, worker amenities and safety to be modified to suit the site conditions of building over tidal water, and the associated environmental controls and supervision of the building process concurrently on five different sites.ÌýAll site deliveries were by water and crane lifting requirements were carried out by floating barge cranes subject to the tidal conditions, which required some night works carried out in consultation with local residents and council.
