Offsite manufacture speeds up school extension

A 26 module school extension was designed, manufactured and installed in just 30 weeks by contractor Module AR, using IKO Polymeric’s prefabricated Amourplan single ply roofing sheets, custom-made for the project.

Parish CofE Primary School in Bromley, South-East London, needed to expand to meet growing demand. The plan to increase the number of entry forms from two to three meant building an additional 12 classrooms, a toilet block, a group room and an entrance lobby. And it all had to be done quickly, with minimal disruption to the existing school. A modular building was the answer, with bespoke single ply roofing sheets in a specific RAL grey provided by market-leading manufacturer IKO Polymeric.

The sheets were installed as a mechanically-fastened roof system in Module-AR’s factory. Prefabricating the different elements (including 30 roof lights and smoke vents) saved significant time on the overall project, allowed for fast-track installation, reduced the number of workforce needed on site and ensured minimum disruption to the school.

The full project – which included removing the existing mobile buildings – provided London Borough of Bromley with programme benefits of 16 weeks. Working with Module-AR, IKO Polymeric won the SPRA Innovation Award for the project in June this year.

IKO Polymeric is exhibiting its range of high-performance waterproofing solutions on Stand B34/306 at this year’s Build Show in the roofing pavilion.
