Health & Safety at Collen Construction

To ensure a constant focus on the importance of safety, Collen has developed and implemented a behavioural safety programme, ‘Creating Safer Sites’. This works by changing behaviours through conversations that make a difference. The impact has been visible in the contractor’s safety culture and the quality of the projects it delivers.
