Ramboll has worked extensively on the M25, including widening of several sections including the J12-15 and T5 spur and J27-30, and was lead engineer for the landmark Cobham Motorway Service Area between J9 and J10.
The work on J27-30 which was carried as part of a JV with WSP for Balfour Beatty/Skanska, attracted particular praise when in 2013 the project won the 2013 Major Project Award, with judges’ commenting, “The team faced one of the biggest challenges in widening one of the busiest motorways in Europe…Despite difficult conditions, cost savings of 18% were achieved and the quickest road widening rate of 1.8km pm.”
On the Cobham Motorway Service Area project, Ramboll worked closely with the client, Highways England, Environment Agency, local authorities and contractor, from planning to completion. Our services included geotechnical, civil and environmental engineering.
