A Ramboll project

The new 18-storey building required wide clear spans and flexibility of floor layouts.

The complex’s two basement levels are designated for parking, with emergency, OPD, diagnostic and surgical facilities accommodated on the ground to fifth floors. Above that are general and private wards, suites, and residential units for the medical staff. A rooftop helipad is provided for the air ambulance service.

The structural system for the building consists of ten reinforced concrete cores grouped in two areas. Steel columns and beams support concrete-filled steel decking for all levels above ground, the beams acting compositely with the decking via welded shear studs. The steel columns carry up to 2,150 tonnes of load and are encased in concrete for fire resistance. Concrete slabs are used for the basement floors.

The building is founded on 2m deep footings under the columns and cores, connected by a 1.1m deep concrete raft that also supports retaining and shear walls. Columns falling outside the basement footprint are supported on isolated and combined footings.

Whitby Wood’s Mukesh Pritamdasani led the structural engineering team that developed the basement structural scheme and proposed the steel superstructure solution, which helped meet the tight project schedule.
