Mr. J. E. C. Farebrother (F) : I have been asked to open this discussion in my capacity as Chairman of the Steering Committee of the LUCID organization. Len Jones has thanked almost everybody except himself and I would like to do that on behalf of the LUCID members.

It is not the intention to add any improved information to that already written on the subject of multi-storey car park design over the last decade, but to record some of the interesting aspects of the design, both structural and otherwise, relating to Basildon's first multi-storey car park which was opened to the public on 6 November 1972.

A great population explosion combined with an acute shortage of building sites have led to intense high-rise building development in the urban areas of Hong Kong. Fig 1 typifies this sort of development and shows a 20-storey block of domestic apartments carried on reinforced concrete walls of slip-form construction. The walls are partly supported at second-floor level on three reinforced-concrete transfer beams BI, B2 and B3, each of which is supported at one end by columns Cl; C2 and C3 respectively. These columns are offset from the upper walls to provide ready access to the two storeys of car-parking located beneath the apartments and are, in turn, carried on caissons at a lower level. S. Mackey and Thomas K.C. Wan
