The deep basement was constructed using a perimeter secant piled wall. The secant piled wall was propped at a number of levels in line with the progression of the basement excavation. The basement structure and superstructure are formed from an insitu concrete frame. The envelope is glazed in a prefabricated modular system. The bespoke facade was designed and fabricated offsite providing efficiencies with the installation schedule. A modular approach was adopted for the internal services installation to optimise the overall construction delivery schedule. The high levels of offsite prefabrication necessitated a detailed understanding of the construction sequence which was reflected in eth construction schedule. The benefits of the high premanufactured value were reflected in the quality of the product for the end user.
