Rock, Ngau Tau Kok, Whampoa Docks, Ap Lei Chau, Quarry Bay, To Kwa Wan and Royal Naval Basin North Arm.
(8) Sounding surveys before and after dredging at all nullah outfalls inside the harbour.
(9) Surveys of foreshore and high water mark at Sham Tseng, Tsing Yi, Aberdeen, Staunton Creek, Ngau Chi Wan and near Rennie's Mill Village, in connexion with the gazetting of reclamations.
(10) Progress surveys on public spoil dumps at Hung Hom, Cheung Sha Wan, Kwun Tong and Sandy Bay, and the Gin Drinker's Bay city refuse dump.
(11) Setting out works for marine bores at Central Reclamation, Lai Chi Chong, Sham Chung, Ping Chau (Mirs Bay), High Island, Silver Mine Bay, Aberdeen, North Point and Lai Chi Kok.
(12) Echo sounding surveys at Waglan Island and Lamma Patch to investigate underwater obstructions.
MATERIALS TESTING LABORATORY
242. Tests on building and engineering materials showed a considerable increase, both in number and scope. The number of tests carried out totalled 19,700 compared with 13,300 during the previous year.
Details are as follows:
No. of Tests (1) Concrete: compressive and flexural strength and chemical analysis 9,686 (2) Cement: physical properties 636 (3) Aggregates: physical properties and purity 2,684 (4) Metals: steel plates and bars for tensile strength and other tests 2,067 (5) Bitumen and bituminous mixtures 1,127 (6) Soils: classification, gradation, compaction, etc. 3,362 (7) Miscellaneous: including strength and other physical tests on hollow tiles, floor tiles, precast blocks, bricks, woodwool boards and plywood, and the calibration of pressure gauges 138243. Of these, 920 were on behalf of private architects, contractors and building material suppliers.
244. Measurement of the temperature changes in experimental road slabs continued, but as the winter tended to be mild it will be necessary to continue these to gather more information before any conclusions can be reached.
245. The acquisition of additional equipment increased the capacity of the Laboratory for triaxial compression and California Bearing Ratio tests and the analysis of bituminous materials. New apparatus was installed for testing the hydraulic strength of pipes, the workability of lime plaster and the impact value of aggregates.
