The erection of a further terrace of six two-storeyed houses on the east side of Happy Valley for quarters for Subordinate Officers was begun and extensive resumptions of property, costing $244,362.60, were carried out with a view to extending the Central Police Station.
The Mongkoktsui Breakwater and contingent works were completed in August, a stone commemorating the event being laid by His Excellency Sir F. H. May, K.C.M.G., LL.D., on the 16th December. The works were completed in two months under the contract time of five years.
The total expenditure to the end of 1915 was $2,181,571.91, a small balance remaining to be paid in 1916, to cover which and other small items, a sum of $30,000 has been provided in the 1916 Estimates.
The breakwater is 3,325 feet in length and encloses an area of 165 acres.
Entrances to the refuge are provided at both ends of the breakwater, the southern being 390 feet and the northern 300 feet in width.
In addition to the breakwater, the work comprised a concrete and masonry pier 450 feet long by 30 feet wide and a reclamation extending over a rocky shoal near the northern entrance. The reclamation has an area of 187,100 square feet and is protected partly by a pitched slope and partly by a concrete and masonry sea-wall. A short masonry pier-head projects from the reclamation.
The depth of water at the entrances at L.W.O.S.T. is 18 feet, the depth within the shelter varying from 9 feet to 18 feet, 82% of the enclosed area has a depth exceeding 12 feet at L.W.O.S.T. and 56% has a depth exceeding 15 feet.
The breakwater consists of a rubble mound 192 feet in width at the base, 20 feet at the top and 44 feet in height. It is faced above L.W.O.S.T. with concrete blocks on the outer side and coursed granite rubble pitching on the inner side and is paved on top with concrete blocks. A trench of an average depth of 9 feet was dredged in the harbour bottom for the entire length and width of the base of the breakwater prior to the deposition of rubble. The rubble mound is composed of stone varying in weight from 1 cwt. to 5 tons, the total quantity deposited being about 850,000 tons.
In all, 12,453 concrete blocks were used in the work, of which 11,379 were pitching and paving blocks of 2 tons each and the remainder principally foot-blocks for the inner slope, which were of the same weight. The foot-blocks for the heads of the breakwater, which are of granite encased in concrete, are much heavier, weighing over 5 tons each and the foot-blocks for the outer slope are wholly of granite and weigh 33 tons each. The granite pitching stones for the inner slope averaged 1 ton in weight, 17,098 being used.
