Leighton Hospital RAAC remediation works
About the project
Leighton Hospital in Crewe was constructed in the 1970s using Reinforced Aerated Autoclaved Concrete (RAAC) planks, but over time this light weight material started to deteriorate.
The Mid-Cheshire Hospitals NHS Foundation Trust (MCHT) has been carrying out a rolling programme of condition surveys and structural inspections since it was first notified of the risks in 2019.
To date, over £55m has been invested in the remedial works, with a further £29.3m to be spent for further works.
MCHT has undertaken surveys of Leighton Hospital and commenced a re-survey programme to continually monitor the condition of the planks.
Where necessary, MCHT has been closing some areas and installing steelwork supports before bringing the affected areas safely back into use.
These supports provide immediate, additional stabilisation and support for the RAAC roof planks before installation of permanent steel supports. They are removed once the remedial work has been completed.
Our role in the project
Aegis provided CDM principal designer services and general health and safety compliance assurance to the Leighton MCHT estates RAAC team and the MCHT capital developments team.
Our main role was to collate relevant information for the development of the pre-construction information document and the hazard and risk register.
Once the principal contractor had been appointed, we ensured suitable information was developed within their construction phase plan and helped identify the management controls needed when working within live wards and buildings.
How we helped
We reviewed all on site construction operations and provided advice and feedback to the contractors and the estates team.
We issued weekly reports, identifying good and bad practices, to the estates team and discussed with the principal contractor to identify causes and controls to be implemented to improve site operations.
We conducted management reviews with the principal contractors to ensure on-site processes and procedures were suitably developed.
We assisted in the development of safe systems of work and permit systems for when contractors or maintenance staff need to access the roof areas, ensuring compliance with the RAAC guidance to limit additional weight on the roof planks.
We worked closely with the structural engineers and surveyors to identify where hazards were present and agreed suitable controls, minimising the impact on hospital staff, patients and visitors but ensuring works could be delivered within the programme timescales.
