This paper describes tendering and construction of underground railway stations in Hong Kong, the contracts for which were let on a design and construct basis. It describes the sites, the soil conditions and the structural concepts chosen to overcome the difficulties foreseen. The method used to construct the main walls, which is the principal structural feature, is described and illustrated. The method adopted is based on local construction techniques but designed by means of modern structural analysis. The preparation of the tenders is described and some of the construction problems are covered. The paper concludes with a discourse on design and construction contracts.
