Wythenshawe Hospital – RAAC

The Challenge

Reinforced Autoclaved Aerated Concrete (RAAC) planks were identified within the maternity unit roof structure, spanning clinical areas, offices, receptions, and theatres across approximately 2,000 sq ft. While long-term deterioration risks were known nationally, the challenge was to safely expose, assess, and reinforce the RAAC planks within a live hospital environment, without compromising clinical operations, patient safety, or service continuity.

Project Goals

  • Safely expose and structurally reinforce existing RAAC roof planks in line with national guidance

  • Deliver the works in carefully phased stages to maintain maternity services

  • Reinstall all MEP services, ceilings, and finishes to return areas to full operational use

  • Provide temporary clinical accommodation to maintain service capacity throughout the programme

The Result

The project delivered a fully reinforced RAAC roof solution through the installation of new structural steelwork, reducing plank spans and loads to improve long-term resilience. Steel supports were installed below the RAAC planks and mortar-packed to ensure even load transfer without further damage.

All affected areas were reinstated with new MEP services, ceilings, and finishes, while additional improvements were undertaken to enhance the maternity unit environment. To maintain uninterrupted care, a temporary Vanguard theatre and clinic were installed and integrated with the main building. The completed works provide long-term structural assurance and operational continuity for the Trust, safeguarding critical maternity services.
