Two building firms have been ordered to pay a total of £72,000 in fines and costs after a floor collapsed during the construction of a six-bedroom mansion in Trafford, injuring three workers.
One of the men sustained major injuries when he was struck by a falling concrete beam, was in hospital for five weeks and has been unable to return to work following the incident on 11 November 2011.
Belmont Homes (Cheshire) Ltd. and Sale-based Waymac Ltd. were both prosecuted by the Health and Safety Executive (HSE) after an investigation found that work at the site had been badly planned, putting multiple lives in danger.
Liverpool Crown Court heard that property-developer Belmont had brought in several contractors, including bricklaying firm Waymac, to help with the construction of the four-storey property, valued at £2 million, on South Downs Road in Bowdon.
During the project, the firms discovered that the frame for the first floor was too high and needed to be lowered. This meant reducing the height of some of the concrete padstones that the frame rested on by lifting the frame and then lowering it back down.
As the concrete beams for the floor were put in place following this work, the floor collapsed. Three of the men fell with it, with the beams falling on top of them.
Two workers escaped with minor injuries but one suffered severe injuries when he put up his left arm to protect his head from a falling concrete beam, weighing around half a tonne.
The 47-year-old from Wythenshawe sustained a crushed arm, fractured ribs, punctured lung, broken collar bone and damage to his back. He has lost the use of his left hand and only has very limited use of his left arm.
The HSE investigation found the work to lower the steel frame had been badly planned, and neither company had considered the potential risk of collapse while the structure was in a temporarily weakened state.
Belmont Homes (Cheshire) Ltd., of Budworth Heath in Cheshire, was fined £33,000 and ordered to pay costs of £15,000 after pleading guilty to a breach of the Health and Safety at Work etc. Act 1974 by failing to ensure the safety of workers.
Waymac Ltd., of Eastway in Sale, was fined £9,000 and ordered to pay £15,000 in prosecution costs after pleading guilty to a breach of the Construction (Design and Management) Regulations 2007 by failing to ensure the structure did not collapse as a result of its work.
