Structural Aspects of the Design and Construction of Quaestor House, City of london

Synopsis This paper outlines the design of the structure for an ofice building in the City of London, highlighting two aspects in particular. First, the underpinning of the surrounding party walls using a novel form of construction, to enable two levels of basements to be excavated. The other is the design philosophy for the superstructure which gives the optimum flexibility of column layout for the irregular plan shape, combined with a shallow floor depth which allows a maximum unimpeded depth for services within the 1.0 m overall floor zone. This was achieved by using post-tensioned flat slabs and structural steel columns. F.T. Hodgson
