Our scope of works consisted of the Main Structure Alterations to the existing building and the General Builders work package. This involved the formation of several new lift pits, new foundations, pile caps and beams, along with the construction of new escalator pits. The partial demolition of existing RC lift shaft and creating a new and enlarged goods lift and the installation of approx. 330lm of new underground drainage including underground sump pump chamber and the demolition of the existing front entrance and forming the new entrance including temporary works design and installation. The works involved various types of diamond concrete cutting and core and bursting works and builder’s works.
The project had major environment constraints including existing tenants and noise restrictions along with phased and section handovers with a challenging programme.
