Contractor: Mansell Construction
Big Foot Systems has supplied support solutions for rooftop plant at the new Cromer and District Hospital in Norfolk as part of a £14.9 million redevelopment project to replace the original hospital on Mill Road, which opened in 1932. Run by the Norfolk and Norwich University Hospitals NHS Foundation Trust, the new dynamic two-storey building was built by main contractor Mansell Construction, designed by Purcell Miler Triton & Partners, with building services installed by M&E contractor Eyre Building Services Group.
Providing accommodation for 14 departments, the new hospital building required a significant number of air handling units and services on its flat roof. However, the lightweight roof build-up of single ply membrane on top of insulation meant any roof-mounted plant needed to be supported on a robust non-penetrative frame. This was necessary to both avoid any damage to the roof membrane and to rule out the possibility of future leaks, as well as ensuring that the plant was not too heavy for the roof.
Eyre Building Services Group therefore turned to Big Foot Systems to provide a solution. Big Foot visited the site to assess the installation, and working with Eyre Building Services designed all the frameworks for the plant in 3D CAD and issued drawings for approval before the frames were manufactured. This enabled the client to visualise the project and make any necessary amendments before manufacture. Once manufactured the systems were delivered flat packed, for quick and easy assembly before the delivery of air handling units.
Richard Fryer, Project Director at Eyre Building Services Group explains; “The project at Cromer Hospital went exceptionally well, we had very good service from Big Foot Systems which made the installation hassle free. The project involved installing external mechanical and electrical services on a Sarnifil roof. We were required to install 11 air handling units, four extract fans and nine condensing units together with pipework and electrical services.
“We worked with Big Foot Systems to design support systems for all of the plant and distribution services, including the acoustic isolation of the condensing units. The primary support system was designed to carry the ductwork, pipework, electrical services and control panels. The systems were rationalised to provide full access to maintain plant and the minimum obstruction to the roof area.”
Big Foot’s support services therefore enabled the safe, efficient, simple and cost effective installation of the air handling units, associated ductwork, pipe and cable on the new hospital building roof. Big Foot’s supports avoided any penetration through the single ply roof, while working to the loading parameters of the designed roof. The support systems also ensured that the plant will be easy to access for maintenance in years to come.
