- Abstract
A reinforced concrete pontoon has been constructed to the order of Sydney Harbour Trust by Messrs. Stone and Siddely, of Sydney, Melbourne, and Geelong. The pontoon is to be placed in position at the eastern end of Circular Quay for the use of the Lavender Bay and Parramatta River ferry service.
The dimensions of the pontoon are: - 100ft. in length, 53 ft. 3 in. wide at one end, and 67 ft. 7in. at the other, depth 7ft. 9 in., with a 32 in. freeboard. The bottom is flat and the sides and ends are sloped to an angle of 70 deg. Special attention has been given to the design of the steel work with a view to enable the construction to withstand the excessive strains likely to occur should vessels be berthing at each side of the pontoon at the same moment. In the construction of the top and bottom of the pontoon allowance has been made for a live load of 150 tons, which will be distributed over the centre length between the posts. The pontoon has been constructed of half-inch blue metal concrete, reinforced with steel bars. The whole construction is divided into 48 watertight compartments, and weighs about 650 tons.
