Mouchel has paid out £2.45M after design failings emerged on a major Essex road project.
Essex County Council hired the consultant as part of an £18.5M plan to extend Roscommon Way, on Canvey Island.
However, Mouchel’s original design for the base of the road was found to be “insufficient”, and new plans had to be drawn up.
The council has now reached an out-of-court settlement with the company.
“Some way through the Roscommon Way road works, we found this company’s original design for the road foundation was insufficient,” said Rodney Bass, the Essex county councillor responsible for highways.
“This meant new plans had to be put forward and work had to be redone. Because of the extra money that had to be spent by Essex County Council as a result, we successfully claimed compensation.
“We are determined to get the best deal for the taxpayers of Essex in every project we undertake.”
The extension, linking Northwick Road to Haven Road, was completed in December 2011. It was the first of two phases to extend the road to Canvey’s Western Esplanade, creating a third main road across the island.
Mouchel confirmed a settlement had been reached.
