327. During the year good progress was made with the reclamation work required for the new airport. Some initial difficulties had to be overcome before all operations were fully co-ordinated but by modifying their methods and augmenting their plant with a large hopper suction dredger adapted for sand pumping the Contractors succeeded in reaching a gross output of over one million cubic yards of material per month.

By the end of March a total net quantity of 1,360,000 cubic yards of mud had been removed and 4,450,000 cubic yards of sand had been dredged and placed in the reclamation; the estimated total net quantities of mud and sand are 2,100,000 cubic yards and 8,000,000 cubic yards respectively. 1,200,000 cubic yards of decomposed granite had been removed from the Kowloon Hills and the Hill of the Sung and placed in the reclamation and 8,400 feet of seawall had been constructed using stone from the Kun Tong quarry, Kowloon hills and the Hill of the Sung. The new fuel jetty was under construction and excavation had started for the culvert of 72 inch pipes which will temporarily carry the flow from the Clearwater Bay Road nullah under the new taxiway. Preparations were well advanced for future work on pavements and services. A stone crushing plant, manufactured locally except for the actual crushers, was erected prior to stock piling of stone for pavement construction. A pipe factory was put into operation and is now making the pipes for the airport drainage system and the 72 inch foul sewer. The completion date for this initial main contract for the airport development is 26th August, 1958.
