Roof-Pro Delivers Roof Access Systems for Royal Derby Hospital

Roof-Pro has successfully completed a bespoke roof access system project at the Royal Derby Hospital for an extension which houses an MRI scanner and associated equipment.

As well as being asked to provide easy and safe rooftop access to the MRI scanner’s rooftop-mounted chiller unit, which generally requires a service check at least once a quarter, Roof-Pro were also asked to design and build roof access systems for the whole new building.

The main elements of this multi-component project were:

  • Providing stable, non-penetrating support for the chiller and Air Handling Units (AHUs)
  • Providing a waterproof method of bringing cables and pipes from the service units down into the building
  • Providing step-over access to the chiller support platform, enabling the units to be serviced and inspected by maintenance personnel.

The project involved a combination of standard and bespoke components designed and built by Roof-Pro, including:

  • Chiller Support Platform – a bespoke component which took into account the weight of the unit and the load-bearing qualities of the roof, and required specially-designed large steel girders. 
  • Roof Penetration Box – this solution was based upon the Roof-Pro PP-3 access riser, which ensures a watertight seal for the point at which the chiller unit's power and water cabling pass through the surface of the roof. 
  • Step-Overs – specially designed to fit the chiller platform and surrounding roof structure, these were tailored components from our Roof-Pro step-over system. 

To successfully deliver this unique project required high attention to detail. Roof-Pro worked closely with two key contractors: Mellor Bromley Mechanical Services, who delivered the chiller and AHUs; and Derwent Valley Construction, who were responsible for the fabric of the rooftop.

All the components were delivered and installed on time and within budget, enabling the primary contractors to complete their projects on time.
