Laing O'Rourke will hear its punishment at Newcastle-upon-Tyne Crown Court on 24 August after a worker was seriously injured when he fell 21 metres from a hospital building under construction in the city.
Laing O’Rourke Construction and Expanded Structures, both part of the Laing O’Rourke Group, are being prosecuted by the Health and Safety Executive (HSE) following the incident on 20 October 2006 at the Royal Victoria Infirmary.
Steven McColgan, 37, from Edinburgh, was working on the construction of the adult block of the RVI when part of a working platform broke away when he stood on it.
He fell 21 metres suffering serious multiple injuries to his head and body.
Both companies have already pleaded guilty to breaching section 3(1) of the Health and Safety at Work etc Act 1974.
