Our Role
To undertake this mammoth basement in the heart of London required exceptional skill and experience in deep excavation design and the construction team appointed Ayesa as their design specialist. Ayesa prepared the detailed design and reinforcement of the deep diaphragm wall along with the design of the foundation piling. The diaphragm wall solution consisted of 1020mm thick panels installed to a depth of 32m below ground level. Ayesa advised on the optimum construction sequence to achieve an efficient solution and to minimise ground movements.
