The client brief required the upper floors to be designed to maximise open area and allow maximum flexibility for prospective tenants and large span cellular beams with a composite metal deck floor slab was selected as the suitable option which allowed for service integration within the structural depth. The below ground elements are designed as in-situ reinforced concrete with a secant piled wall to the perimeter. Excavation is completed with Secant Props with Flying Shore rops have been used to maximise the working space for the construction of the three levels of basements below.
The façades required complex and innovative design including a planar column free glazed façade fronting onto Dawson Street with an architectural ‘brise soleil’ outside of this from 1st – 5th floor suspended (top-hung) from the 5th floor terrace structure. Elsewhere intricate structural design was required to support façades in a wide array of materials including Portland limestone, cast bronze, aluminium and brickwork.
The works include high specification Cat A office fit-out to penthouse level which will be a showpiece for marketing to prospective tenants. The project was executed and handed over to BIM Level 2.
