Laing O'Rourke Construction has been fined £80,000 and ordered to pay £10,000 costs at Liverpool Crown Court today.
Laing O'Rourke employee, William Taylor, sustained multiple serious head and other injuries and narrowly escaped falling three floors to the base of a building in Grosvenor's £1bn Liverpool One regeneration scheme.
Two other workers also escaped injury whilst working in the same unprotected area.
Taylor sustained his injuries on 13 August 2007, when he fell over three metres during the construction of concrete stairs inside one of the main apartment blocks on the project.
Laing O'Rourke Construction pleaded guilty at an earlier hearing at Liverpool Magistrates Court to a charge under the Health and safety at Work Act 1974.
