Through our construction division we contract with end-clients and large civil or M&E contractors to deliver packages of building services, telecommunications and other systems infrastructure across the UK overground and underground rail networks.

Case Studies >

We work in complex, heavy construction environments where the operational railway and travelling public come first every time. This drives our focus on planning, recruiting, training and project management. Our approach is to provide an engineering led, collaborative service. We strive to understand our client's challenges and how we can best work for this common goal.

Many of our projects involve track access and possessions where communication and planning are crucial. Our planners work with our client's team to ensure we have fully integrated work flows.

At the heart of our thinking is the safety of individuals and the impact of our work on the operational railway. For this reason we embed safety at every level.
