Phase 2 of the WMC was designed by the then newly qualified Tim Green and Keith Vince of Capita Architecture, formerly called Capita Percy Thomas and now part of Capita Symonds, with Arup Acoustics again providing the acoustic design. The main contractor was again Sir Robert McAlpine Ltd, with MJN Colston Ltd responsible for the design and installation of all the mechanical, electrical and public health services in the building. Other subcontractors on the project included URS Corporation, Davis Langdon and Hulley & Kirkwood.
