Manchester Minshull Street Crown Court heard that in the summer of 2015, to support the construction of the A556 bypass in Cheshire, work had started on a pier to support a bridge. This involved erecting a steel cage. On 3 August, two workers were working on the structure in a platform, when it collapsed. The cage crashed into the MEWP, causing it to fall on its side.
The first employee sustained life changing head injuries and the second a leg fracture. A third worker nearby just escaped in time.
An investigation by the Health & Safety Executive (HSE) found there was no temporary support for the reinforcement cage during construction of the central pier. Costain Limited was principal contractor and Brenbuild Limited was appointed by Costain to construct seven bridges and an underpass.
Costain and Brenbuild were both aware that the cage was visibly leaning and that workers on site had raised concerns. Neither company recognised the inherent instability of the reinforcement cage or took measures to ensure the work could be carried out safely. Brenbuild failed to stop work to prevent injuries from the risk of collapse and to implement control measures to prevent instability. Costain failed to plan, manage and monitor construction of the central pier.
Brenbuild Limited of Parkway Business Park, Scunthorpe pleaded guilty to breaching sections 2(1) and 3(1) of the Health and Safety at Work etc. Act 1974. It was fined £80,000 and ordered to pay costs of £21,730.11.
Costain Limited of Vanwall Business Park, Maidenhead, pleaded guilty to breaching sections 2(1) and 3(1) of the Health and Safety at Work etc. Act 1974. It was fined £1.2m and ordered to pay costs of £21,644.51.
HSE inspector Deborah Walker said after the hearing: “This incident could have been easily prevented and the risk of collapse should have been identified by both companies. If a suitable safe system of work had been in place, this incident would not have occurred, and the two workers would not have suffered these injuries.”
