I have ascertained that the Hongkong and Whampoa Dock Company desire to con- struct a pier for the handling of heavy machinery near the entrance to the New Graving Dock now under construction. The position and extent of area which may be occupied for this purpose, without prejudicing this scheme of development, is shewn coloured light pink cross-hatched darker pink on Drawings Nos. 3 and 4.
Type of Construction.
It is recommended that all the quay walls in this scheme be constructed in block- work with ashlar-faced masonry superstructure. It will be found possible by dredging. to found portions of the quay walls upon natural ground; and where hard ground is not obtained at suitable depths to be reached by the blockwork, the walls should be founded on pell-mell rubble mounds deposited in trenches dredged to depths at which suitable foundations do exist. A pitched slope superstructure founded on a rubble mound brought to the level of low water will protect the south side of the coal depôt and the frontage adjoining Jetty No. 4. In regard to the three piers and dolphin, it is proposed to carry out their construction in reinforced concrete: Groups of steel piles encased in concrete and suitably braced above low water level will carry an ordinary type reinforced concrete decking. The piles over the base of the mound referred to should be driven before pell- mell rubble is deposited. Selected filling material should be used to fill in the spaces between the walls of the jetties and also behind all other quay walls for a distance of about 250 feet where the widths will allow. The remaining areas of reclamation may be filled in with material dredged in connection with the carrying out of the scheme, the surplus being deposited within the areas of proposed further reclamation at Shamshuipo. Having regard to the development of the reclaimed areas, careful consideration will require to be given to the question of lower initial cost of reclamation by the deposition of dredged material as against the higher initial cost by the use of more suitable filling.
A typical cross section of the scheme is shewn on Drawing No. 11.
