224. Design work was commenced as soon as the order to start work was given, and by the end of the year was nearing completion. In order to save working time, certain preliminary works were put in hand departmentally and extensive survey work continued.
225. The formation of access roads and sites for coolie lines was commenced and plans prepared for coolie lines and Engineer's quarters. The design of a landing jetty was undertaken by the Port Works Office; anti-malarial work was commenced by the Medical Department and forestry work by the Forestry Department.
Miscellaneous Work
226. Central Reclamation Scheme. Further borings were carried out in connexion with this scheme. A realignment of the cross harbour main to avoid the new site for the ferry pier was also approved and the preparation of an indent for the necessary pipes was almost completed at the end of the year.
227. Boring Work. In addition to the Central Reclamation Scheme, the boring gangs were fully occupied during the year on site investigations for the Tai Lam Chung Scheme; the realignment of Kennedy Road for the Chief Engineer, Roads Office; and the foundations of the new Central Police Headquarters for the Chief Architect.
228. Prestressed Concrete. Included in the five-year programme of major works are a number of new service reservoirs which require approximately 230,000 sq. ft. of roofing which it is possible to standardize. In view of this, consideration was given to the use of prestressed concrete beams and slabs for the roofing. Allowing for the purchase of the equipment, its setting up, and the required prestressing wire it is considered that this type of construction should show a considerable saving in cost over ordinary reinforced concrete on the whole programme of
