(7) Current observations in the eastern part of the Hong Kong Harbour for the construction of a tidal model.
(8) Sounding surveys for the siting of two vehicular ferry piers at Kowloon Bay and North Point.
(9) A seabed survey from Aberdeen to Ap Lei Chau for a 6-inch cross-harbour fresh water main.
(10) A survey of the foreshore with soundings at Ma Wan, Kap Shui Mun, for the extension of the existing pier.
(11) Routine surveys for pier leases and permits.
(12) A shoreline survey around Chek Lap Kok Island and Tung Chung Bay to establish control points for the Hydrographic survey of the Channel and the approaches to the proposed pier.

MATERIALS TESTING LABORATORY
231. 11,239 tests were carried out in the laboratory and included:
(1) 5,693 tests on concrete for compressive strengths and moduli of rupture.
(2) 293 tests on the physical properties of various cements from Palestine, Japan, India and Rumania.
(3) 2,038 tests on aggregate for gradations, crushing strengths, specific gravities, bulk densities and organic impurities.
(4) 976 tests on mild steel rods for tensile strengths, percentage elongations under failing loads and characteristics when bent cold.
(5) 1,051 tests on the physical properties of bitumen and analyses of bituminous road mixtures by the hot extraction methods.
(6) 1,156 tests on various types of soil for the classification and estimation of bearing capacities and coefficients of permeability.
(7) Thirty-two miscellaneous tests on hollow tiles, precast sand-cement blocks, wood-wool boards and bricks.
232. In addition to routine tests, investigations were made into:
(1) temperature changes in concrete road slabs covered with bituminous surfacings of various thickness;
(2) local laterite soils for their California Bearing ratio values and stabilization by hydrated lime;
(3) the suitability of iron mine wastes as fine aggregate for concrete making.
