TCM produces ecological surveys and assessments for a range of Network Rail electrification renewal and enhancement projects. We are impressed with Sarah’s (our contact at TCM) professionalism on identifying ecological issues by actively understanding our scope of works. She also has excellent knowledge of gathering / analysing in-situ evidence of protective species / invasive vegetation. Her reports help us immensely on addressing biodiversity actions at the early stage of the project lifecycle. Ivan Lee - Design Engineer, Network Rail
