Princess Royal University Hospital, Bromley

Perega provided civil and structural engineering services for the new-build Endoscopy and Diagnostic Centre at Princess Royal University Hospital, part of King’s College Hospital NHS Foundation Trust.

The two-storey facility features a reinforced concrete frame and expands the hospital’s diagnostic capacity. Working alongside Gilling Dodd and Kier, Perega provided engineering input to address the specialist structural requirements associated with the clinical environment.

Designing for Specialist Clinical Requirements

The building required structural solutions to accommodate a range of heavy clinical equipment and specialist installations.

Perega designed the first-floor slab to support water tanks and engineered the structure to accommodate surgical pendant arms suspended from the sofit. The floor plates also had to meet strict vibration sensitivity requirements, which are particularly important within surgical environments where excessive movement could affect delicate procedures.

These requirements were incorporated into the structural design to provide the necessary stability and support for the specialist clinical spaces.  

Bridging an Existing Underground Tank

A significant site constraint emerged when an existing tank was discovered beneath the proposed building footprint. The structural capacity of the underground feature was unknown, meaning the new building could not simply be supported directly above it.

To overcome this constraint, Perega designed a substantial transfer structure at ground-floor level to bridge the existing tank and safely support the building above.

The solution incorporated large-scale transfer beams measuring 1.4m deep and 2m wide. This enabled the new facility to be constructed while avoiding reliance on the existing underground structure and without impacting the subterranean infrastructure.

The project was successfully completed, providing additional endoscopy and diagnostic capacity at Princess Royal University Hospital.
