Project: Retail Store, Banbury.

Products: Flexi heavy & Flexi access – Heavy Duty Frames & QUADs.

Services: Plantroom, generator, air-handling units and bespoke access solutions.

Roof build-up: Warm roof design – Mastic Asphalt.

Woodward, the mechanical services contractor on the project, had a number of different heavy building services that required supporting. This included a 7500kg plantroom, 3520kg generator, two 5000kg air-handling units and a 3500kg air-handling unit.

Using its Flexi-Heavy Duty range of supports, Pump House designed and calculated individual frameworks for each item of plant, paying particular attention to ensuring that the correct load management through our frames, back down to the roof finish, was achieved. Pump House met the contractor on site during the assembly of frameworks to ensure a trouble free installation, prior to the crane lift of the equipment shortly after. It also prepared ahead of the installation AutoCAD drawings depicting the correct support of each unit, as well as pressure and roof loading calculations.

In addition, Pump House was asked to supply the associated step-ups and access platforms required for the maintenance of the services. These were designed in accordance to British Standards, and supplied in kit form for installation after the plant was in-situ.

The flexible nature of the Pump House systems, combined with even load distribution through its non-penetrative feet, meant this removed the risk of potential leaks and thermal cold bridging, which may occur with traditional supports breaking through the waterproofing. The lightweight and portable nature of the products made installing the Pump House system very simple and fast.
