Top 10 Best Civil Engineering Firms in Spelthorne

Civil Engineering in Spelthorne

Few boroughs in England have infrastructure needs as complex as Spelthorne. Bounded by the River Thames and home to major reservoirs such as Queen Mary, King George VI and Staines reservoirs, the borough plays a vital role in London's water supply. It lies beside Heathrow Airport and is crossed by the M25, M3 and A30. Flood risk along the Thames has also made it a focus for the River Thames Scheme, a major flood alleviation project led by the Environment Agency and Surrey County Council to reduce flood risk between Egham and Teddington.

This guide highlights ten of the best civil engineering firms with expertise relevant to Spelthorne's infrastructure. We considered technical capability, project experience, innovation, sustainability and reputation.
