The project

This fast-track project was for the strip out and reconfiguration of ward accommodation to form an endoscopy decontamination unit and two operating theatres as well as circulation areas.

The new theatres and unit were constructed with blockwork walls and some minor demolition works were required to create new doorways on to the corridors for access and egress.

Substantial support steelwork was required in the roof space for lights and medical gases, which also required a new containment route. The mechanical & electrical requirements included automatic laser locking on the doors and high specification air balancing systems within the theatres for effective infection control.

ISG carried out some fit out work, which included the installation of drug cupboards, preparation units, equipment holders for the anaesthetist and tracking systems.

The added value

Some design changes were required during the project which included the rerouting of ducting systems due to a risk of air decontamination. Alterations to the steelwork were made to accommodate equipment changes. ISG also carried out a report on air performance with improvements incorporated into the work schedule. Identified penetrations were collared and made good plus the concrete works included special acoustic foam insulation. 

Despite a very rigid handover date due to operations having been booked, all design changes were accommodated within the programme.

ISG suggested changes to specifications where appropriate. These included changing the door specification, saving circa £30k and four weeks on the programme. ISG also changed the wall cladding specification from a white rock to a similar product, saving circa £10k.


Improvements to the air performance including new insulation improved the thermal performance of the building. The mechanical & electrical systems are much more efficient. ISG salvaged lighting from the strip out works which was returned to the client for re-use. Brick and blockwork and plaster were all sent to be recycled and in total 95% of all site waste was recycled.

The doors, timber, white rock style cladding and plasterboard were all procured from sustainable sources. Local builders’ merchants were used and the doors and timber were sourced through local suppliers.

ISG sourced site operatives through a local agency and utilised local subcontractors where possible, including for the partitioning, ceilings, plastering and mechanical & electrical installations. On-site training was encouraged and a number of apprentices supported.

“ISG offered a helpful approach to managing the construction within the difficult restrictions of the hospital and its staff. I was very happy with the team, and the two site managers were the best we have had in years.”
