This project encompassed many of the services offered by GM Piling including CFA, cased CFA and secant wall piling. GMP reduced the programme by one week on the secant wall and by three days on the cased CFA piling. The design required the secant wall deflection tolerances to be limited in order to satisfy third party requirements. The cased piles within the basement saved the client cost and programme as less steel and concrete was installed, and less pile cropping was required.
