FACTORY prefabrication of sprinkler systems has produced £500,000 in savings for retail client B&Q.
Project manager Sworder Belcher Holt undertook the sprinkler retrofit programme for 200 B&Q stores, with AC Engineering building the pump rooms.
Prefabrication meant that the entire process for the pump room construction, with the exception of building the base, could be done off-site.
Peter Chilton, commercial director of AC Engineering, said: 'The approach is geared to save time on site with most of the work being carried out in a controlled situation at the workshop.'
Mr Chilton added that prefabrication minimised disruption to staff and customers generating savings of £15,000 per store.
He said: 'It eliminates the need to store blocks, bricks, sand, mixers and so on in valuable parking spaces. There is less disruption to store deliveries and the area is far safer for customers as it does not become a building site.'
Rob Holloway, director of Sworder Belcher Holt, said: 'The off-site working is to fixed cost so there are no hidden extras. There is a 10 to 15 per cent in actual cost savings which results in a significant saving to the client.'
Over the past year about 38 pump rooms have been installed, with a further 43 planned over the next 12 months.
