Progress on the work continued slowly. The dredging of trenches for the rubble mounds was completed in January. The whole of the rubble was deposited during the year, but was not trimmed to lines and levels. The pitched rubble embankment at the North West end was completed. The work of filling progressed very slowly, approximately 102,000 c. yds. being deposited. Of the estimated total quantity of 265,000 c. yds. only 194,117 c. yds. had been completed by December 31st. The slope to the East face of the reclamation was turfed for a length of 375 feet.
The contract time expired on 16th November and the Contractor was informed that, unless he could show a great improvement in progress during the next 3 months, no consideration could be allowed him for the effect of the labour trouble commencing in June, nor for the difficult nature of his cuttings.

Quay Wall at North Point, Marine Lots 430 & 431.-As alluded to by the Director of Public Works in paragraph 9 of his Report for 1924, the Ching Siong Land Investment Company is developing large areas of foreshore at North Point known as Marine Lots 430 and 431. This development includes the construction of a deep sea wall in front of the two lots, for the design and the supervision of the construction of which by this Department, the Government is responsible.
A Contract for the construction of the quay wall prepared by the Department was entered into between the Principals and the Netherlands Harbour Works Co. on 12.6.24 to complete the Quay Wall works for the sum of $1,950,000 within two years.
The work consists of the construction of a quay wall 1,693 feet long in sloping blockwork founded on a rubble mound, with masonry superstructure, providing a depth of water alongside of 30 feet below Ordnance Datum, together with contingent works. The blocks range from 18 to 55 tons each, the majority being over 53 tons each, and are set by a floating crane with the assistance of divers. The total depth of blockwork is 37 feet, on which is formed a plinth or levelling course of cement concrete. The superstructure is of granite masonry facing, backed with cement concrete and surmounted with a granite coping. The blocks are manufactured in two blockyards, one situated about a mile away from the site and the other near the West end of the wall.
