Precast steps forward

摘要

Cornish Concrete Products has designed, supplied and installed two feature staircases for a new 9,350 sq m four-storey office building at BP's International Centre for Business and Technology at Sunbury-on-Thames. Working from an outline design of the staircase by Buro Happold, Cornish Concrete Products' engineers carried out the detailed design of the individual precast elements and connections. During this process, the proposed in situ concrete solution was switched to precast to achieve the required finish and quality. All precast elements cantilever from a curved central spine beam, which is partly reinforced with 25 mm solid steel plate.
