A KINGSTON company was one of two fined after a construction worker died in an accident while building Heathrow Airport's Terminal 5.
A fellow construction worker was also left paralysed after the accident, which happened when they were building a multi-storey car park.
SBG Services of Kingston and Laing O'Rourke Infrastructure Ltd, of Dartford, were fined a combined £105,000.
Both companies admitted breaching two sections of the Health and Safety Act and were fined at Isleworth Crown Court on Friday, November 6.
Matthew Gilbert, 27, from Plymouth, died when he fell 17 metres to the concrete floor below, when a concrete slab he was standing on collapsed.
Parminder Singh, 21, from Slough, also suffered 'life-changing' injuries in the fall.
Karen Morris, HSE inspector, said: "The tragic death of one man and the serious injuries suffered by his colleague could have been prevented if more robust systems were in place. It is vital that safety critical components are inspected to ensure that defective equipment is not used."
