Project Summary

Burrows Graham is responsible for civil and structural engineering design services for the construction of a new CT Scanning Suite on Southport Hospital. As with most hospital sites, space is an absolute premium. A courtyard between 2 wings has been determined as the best position for this much needed additional facility. This site is very constrained and connects to the existing building on 2 sides while being within 2m of the existing building on the other side. The ground conditions were particularly poor with bottom driven steel cased piles being used to support the foundations and slab. A steel framed superstructure was adopted with SFS panels providing the building envelope and internal partition walls. The roof is to be concrete profiled metal deck to support roof mounted plant. A plant room is positioned over part of the roof.

There are also internal modifications to the existing CT suites included in this project. This has necessitated the back analysis of the existing slab to ensure it has sufficient stiffness to avoid excessive vibration during scanning operations.

Key Engineering Challenges

• Working in an incredibly tight site which remained operational throughout
• Particularly poor ground conditions required piling to be undertaken in close proximity to consulting rooms and wards. Bottom driven steel cased piles minimised the acoustic impact. Careful vibration monitoring was required adjacent sensitive apparatus
