Quay Wall at M.L's 430 and 431, North Point.-This work referred to on page 190 of last year's Report.
The work of constructing the quay wall, except the levelling of the berm in front of the toe, was completed by the end of the year. The contract time was exceeded by about 5 months; failure to complete the work to time, was brought about by labour troubles.
About 10,000 cube yards of sand was used to form the portion of the foundations between 200 feet and 550 feet Eastwards from the Hong Kong Electric Company's property, this sand was brought up to a level of 47 feet below Ordnance Datum and the foundations were completed by the deposition of pell-mell rubble to a level of 33 feet below O.D., the latter being the level to which the quay wall is founded. The foundation for the remainder of the wall was constructed by using pell-mell rubble only, the total amount of rubble required for this purpose being about 100,000 cube yards.
A total of 39,178 cube yards of concrete was required in the construction of the quay wall, of the above amount 38,145 cube yards was used in making precast concrete blocks which were set to form the wall by means of a floating crane, the remainder of the concrete was deposited in site to form the portions of wall at the bends.
The wall is finished by a masonry superstructure, with granite cope. Sixteen bollards were fixed for the use of shipping, and three landing stairs were constructed to give convenient access to the wharf and public roadways.
