The dramatic 18-storey tower that is the centrepiece of the Birmingham 1 development incorporates Corefast which was used to construct the central lift/stair core.

In addition to saving six weeks on the construction programme, Bi-Steel’s high strength and rigidity meant that the four reinforced concrete cores originally specified could be replaced by a single Corefast core and supplementary conventional vertical bracing. 

Corefast also offered health and safety benefits by eliminating the need for temporary formwork and facilitating safe, enclosed working at heights.
