Slough diagnostic hub delivery: modular build and BIM lessons for project teams
Reviewed by Tom Sullivan
First reported on The Construction Index
30 Second Briefing
A £25m modular community diagnostic hub at Upton Hospital, Slough, has been delivered by Western in under a year, with pre-assembled modules made watertight within five days and internal fit out completed in a matter of days. Using BIM 3D modelling and full offsite fabrication, Western acted as turnkey contractor, also delivering external works including a reconfigured car park with EV charging infrastructure in a live hospital environment. The hub will operate 12 hours daily with capacity for 150,000 tests a year, including MRI, CT, ultrasound, respiratory and cardiology diagnostics.
Technical Brief
- Offsite modules were made watertight within five days of installation on the Upton Hospital site.
- Western acted as offsite manufacturer and turnkey contractor, controlling design, fabrication, build and fit-out.
- BIM-led 3D modelling underpinned coordination of services and clinical layouts before fabrication commenced.
- Modular approach explicitly targeted reduced disruption, waste and programme risk in the live hospital environment.
- Scope extended beyond the building to reconfigure the hospital car park and integrate EV charging infrastructure.
- Community consultation in 2023 shaped the hub’s configuration to address local health inequality in Slough.
- Client is NHS Frimley Health Foundation Trust, with Western’s MD emphasising “advanced off-site manufacturing” and “full turnkey approach”.
- Project illustrates modular delivery’s suitability for complex clinical environments where decanting and shutdowns are constrained.
Our Take
Within the 731 Infrastructure stories in our database, very few UK healthcare schemes match the Slough diagnostic hub’s combination of sub‑£30m cost and sub‑one‑year delivery, signalling that this modular approach is at the faster, lower‑capex end of current public-sector building practice.
Achieving a watertight envelope at Upton Hospital Slough within five days of module installation is in line with the quickest modular roll-outs seen in our recent hospital and school coverage, suggesting Western’s method could be competitive for time‑critical NHS Frimley Health Foundation Trust upgrades elsewhere.
Running the Slough diagnostic hub for 12 hours per day positions it closer to urgent-care and transport-hub operating patterns than typical outpatient facilities in our Projects-tagged pieces, which is likely to drive higher utilisation of imaging and diagnostic equipment and influence future NHS estate planning.
