Project Requirements

Initially plinths & steel beams had been specified to support the roof plant, however, concerns were raised about the integrity of the roofing membrane. Using traditional fixed roof supports would have meant that any future repairs to roof surface could require the AC plant to be decommissioned.

The potential risk of decommissioning services was seen as having an unacceptable impact on the Trust’s operations. The initial plinth design were therefore rejected in favor of a the more flexible Big Foot Systems.

The total weight of plant on the PVC roof was understood to be in excess of 9 tons with several AHU’s weighing approx 2.5 tons. The Big Foot Systems team worked with the architect, building services engineers and structural engineers to design a complete roof support system for all roof plant and associated plant services.

In addition to improve the movement of the framework on the site, Big Foot Systems tailored the packing requirements. This meant that the frames could be simply craned up onto the roof top.
