Delivering Light rail schemes affords us the opportunity to enhance regional quality of life and have a positive impact on local communities, the environment and economy.

We provide affordable, urban public transportation to connect residents and the neighbourhoods where they live, work and play. We seek to work with our customers to identify optimal engineering and value based solutions through Early Contractor Involvement considering the impact of design decisions on a whole life cost basis. Our skills and experience have developed an enviable portfolio of projects covering all aspects of light rail construction and maintenance from which we are able to draw significant learning and experience.
