Special design consideration was given to the ground floor slab to isolate it temporarily from the columns and perimeter retaining/support walls, thus solving restraint problems until the slab had finished all movements at which point the slab was locked to the columns by grout infill. The total differential deflection between adjacent floors after the installation of the cladding will be limited to the lesser of span/500 or 12mm. The caisson roof prestressing tendons are the 7K15 type and are horizontal, straight and approximately 50 metres long. Freyssinets solution was to add extra reinforcement/tendons and Freyssibar. Senior Engineer Execution . A standard slab thickness of 350mm was adopted generally across the structure. Most precast, prestressed concrete is actually pre-tensioned-the steel is pulled before the concrete is poured.Post-tensioned concrete means that the concrete is poured and then the tension is applied-but it is still stressed before the loads are applied so it is still prestressed. As part of the design process, consideration had to be given to the tie forces resulting from the walking columns.

WSP was based on a proposal of post-tensioned slabs to many of the superstructure levels. Access to the internal face of the external blister was difficult, due to the need to place large components in a tight space, which included the placement of ultra-high strength concrete which could not be traditionally pumped due to the steel fibres causing irreparable damage to colloidal mixers. The structural challenges of hospitals vibration performance, flexibility for penetrations and location of setdowns in the slab surface have all been readily accommodated in the design and construction.
