cubic yards of fill will be required at Kun Tong. This filling is available from adjacent hills which appear to consist mainly of decomposed granite. To gain additional information on the nature of these hills, and also on how the existing refuse dump will react under the weight of fill, a pilot contract for 300,000 cubic yards of filling was let. Work commenced on this contract
in February and by the end of the year 65,000 cubic yards of spoil had been dumped. To protect the seaward end of the reclamation, 1,000 feet of sea wall consisting of precast concrete toe and foundation blocks with granite rubble masonry face-work was under construction on an existing rubble mound foundation.
217. Rubble Mound at Gin Drinkers' Bay. This work was commenced in January to form a new site as a Colony Refuse Dump, the Kun Tong site now being required for another purpose. To contain the refuse within the allotted area it was decided to construct a rubble mound connecting Tsing Chau Island and the mainland. This mound 1,500 feet long is being constructed by tipping graded quarry stone of up to one ton weight upon the sea bed formation and will eventually be brought up to a level of 5 feet above Highwater Spring Tides. At this level a concrete foot-path, providing access between the island and the mainland, will be constructed. Some 7,000 cubic yards of stone had been tipped by the end of the year out of a total of 80,000 cubic yards required.
218. Central Reclamation Scheme. This scheme was almost completed during the year except for a small part of the earth filling. When completed it will provide a further 9 acres of reclaimed land and contains the proposed site for a new City Hall. Consequent on the diversion of the two 21-inch diameter cross-harbour water-mains, work was recommenced in December on the construction of some 267 feet of sea-wall to close the gap previously left open for the work on the cross-harbour pipelines. Before dumping the rubble foundation mound for the portion of sea-wall which fronts the new Star Ferry Pier, it was necessary to drive some of the 80 feet long reinforced concrete piles required for the future pier.
