While the factory end of off-site production (prefabrication) is a smooth processes, there are many on-site issues to be considered. MARCUS DICKS explains.
PAUL COOPER shares his views as an off-site manufacturer of the wider issues addressed by the concept.
Individually designed rigs built by Keston for a large housing project combine a boiler, hot-water cylinder, underfloor heating panels and mains transformers, including electrical switchings for domestic appliances.
As examples of the space-saving benefits of prefabricated equipment, skid-mounted units supplied by Rycroft for six Royal Navy destroyers are the ultimate. Not only is a multitude of equipment packed into the minimum footprint, but all components are accessible from the front for ease of servicing.
Prefabricated services modules have saved one week per floor in installation time in a refit of three floors of 10 Exchange Square in the City of London. Phil Mardle, construction manager with M&E contractor Bancroft Group, says, ‘This was our first exercise in the use of off-site prefabricated services in this manner, and we therefore used it on a fairly limited scale. We will almost certainly, however, expand the scope of its use on future projects.’
