initial dredging work as underwater cables had to be moved, protection provided for the cross harbour water mains and a scheduled time-table arranged and co-ordinated with the Ferry Company and Naval Authorities.
23. A further major reclamation scheme, started before the war and re-commenced in 1947, was taken a stage further when 654 ft. in. of sea wall was constructed at North Point at a cost of $131,000.00. This sea wall followed the standard pattern of the section of walling constructed on this site last year and forms an extension to it. Three layers of concrete blocks were placed on a rubble mound foundation to raise the level from C.D. to +5.25 C.D. and on top of these blocks a granite faced, concrete retaining wall was constructed to give a final cope level of +14.00 C.D. This seawall encloses a further 230,000 sq. ft. of foreshore, part of which was reclaimed by public dumping and forms a valuable additional area for development.

124. Part of the reclaimed area at North Point has been allotted to this sub-department as a depôt, pre-casting yard and site for the permanent P.W.D. Testing Laboratory to replace the present site at Arsenal Yard which is required for the new Police Headquarters. Large areas of concrete surfacing were laid to form the central pre-casting yard and the provision of heavy lifting appliances has facilitated the work of loading heavy mass concrete blocks on to transporting barges for delivery to the various sea wall or pier projects.
