3.15. This Division, under the control of the Government Structural Engineer, is responsible for the structural design of all projects undertaken by the Architectural Office. This includes maintenance work, the preparation of structural drawings, details and reinforcing bar bending schedules, the supervision of reinforced concrete and structural steel works on site and the design and supervision of piling and foundation works, together with advising other divisions of the Office on the structural feasibility of projects.
3.16. The Division is divided into three groups, each headed by a Senior Structural Engineer, which deal respectively with major works; minor works, military works and maintenance; and Resettlement and Government Low Cost Housing projects. Each group is staffed by varying numbers of structural engineers and assistant structural engineers with supporting technical staff.
3.17. During the year, the Division completed the structural design of over 180 separate new buildings and supervised foundations and structural works at over 130 sites and the sinking of over 6,400 precast and in-situ piles.
3.18. Difficulties were encountered in the piled foundations at several sites. One of the most difficult sites was the Kwai Hing Government Low Cost Housing Estate, where underground obstructions prevented the use of precast concrete piles. Concrete piles cast in-situ were used and required careful control to overcome the effects of underground water and a compressible soil stratum. Other problems included piling on a steep slope at Ho Man Tin site for Government service flats and the formation of piles in tight corners between existing structures at Kai Tak Airport Terminal building.
