STRUCTURAL DESIGN DIVISION
Chief Engineer:
J. D. DUNCAN, C.Eng., F.I.C.E., M.I.Struct.E., M.I.H.E.
9.27 This division is responsible for the structural design of all major highway structures and bridges to be built by Highways Divisions. It provides consulting facilities to the Civil Engineering Office on structural matters and carries out checks on structural designs for highways projects prepared by consulting engineers.
Design Projects
9.28 On Hong Kong Island, detailed design for an underpass at Shek Pai Wan has continued and preliminary planning has been undertaken for a section of an elevated road on Pokfulam Road and a flyover at Lau Sin Street.
9.29 In Kowloon, design work was carried out on two large projects, the elevated road between Gascoigne Road and Tong Mi Road, and the elevated road between Prince Edward Road and Lai Chi Kok Road. Other design work undertaken during the year included several footbridges and a grade-separated access to the Airport Maintenance Area from Prince Edward Road. Preliminary planning was started for the extensive structural works required between the Airport Tunnel Road and Kwun Tong.
9.30 Design work has continued on four footbridges for the New Territories, and preliminary planning for Tsuen Wan By-pass has been undertaken.
Design Standards
9.31 Further work has been carried out on establishing design standards for highway structures, and a fairly comprehensive set of structural standards is now available for the more straightforward cases. Data for a range of standard beams were compiled. The use of computers for solving design problems continued. The Government computer ICL1903 was regularly used to solve structural problems.
