One Sherwood Street, Piccadilly Circus

For over two years A-squared has been supporting Martello Piling, Erith Group, Waterman Partnership, Land Securities design and Construct piled foundations as part of the redevelopment of this central London site which sits behind the famous electronic billboard on Piccadilly Circus. Several buildings are being retained along with their facades whilst other buildings are being demolished and replaced. The existing basement is being deepened and extended. The piling works were undertaken in both restricted and unrestricted working areas. The piles and their layout had to be designed to be compatible with the capability of the Martello piling rigs in these working areas. The piles were designed with a reduced factor of safety which was then validated by load testing.
