This poses a number of logistical and technical challenges. Below ground, a 27 m deep basement incorporates a PBT centre of approx. 81,000 ft2 arranged over four levels, with four PBT rooms at the base of the facility. Above these levels there are six storeys of purpose built inpatient facilities, including eight operating theatres. SCIA Engineer was used to analyse and design the structure for the entire project. Firstly, it was linked to Revit during its early stages. Once the complete structural model was formed, non-linear analyses were run, and code dependant deflections were assessed on the raft and floor slabs in a separate model. Load panels were added to the superstructure to determine wind forces. The nature of the building meant that large hydrostatic and heave forces were present at the end of the excavation works. This presented challenges in ensuring that the piles and diaphragm retaining walls could withstand the uplift forces, with the raft rigid enough to transfer forces effectively to utilise the capacity of each pile. These then had to be checked against the final stage (i.e. building completion), whereby loading would be reversed with the retaining walls and piles in compression.
