Kier has won a 12-month contract extension with Surrey County Council worth £40m.
The original contract started in 2011, then in 2017 Kier secured a four-year extension that will run until April 2021, which is when the new 12-month extension will kick in.
The contract covers highways maintenance and improvements, as well as the continuation of the S-Skills academy, which was launched as part of the contract in 2017.
'S-Skills for Highways is a 16-week programme operated in conjunction with Surrey County Council and provides vulnerable young people and adults with the opportunity to learn basic highway works that will help improve their chances of employment,' Kier said.
It comes on the back of a wide range of charity work Kier has done with OnSide Youth Zones, which provide youth centres for kids from deprived or vulnerable backgrounds.
Joe Incutti, acting group managing director at Kier Highways, said: 'We are very proud to have been working with Surrey County Council for nearly 10 years delivering highways maintenance and improvements, and particularly proud to have had the opportunity to make a positive social value contribution, which will benefit residents and communities in Surrey for many years to come.
'This contract award is further recognition of the long-term collaborative relationship that has been built between Kier’s extraordinary Surrey Highways team, and Surrey County Council. We are delighted to have been given the opportunity to continue our relationship with Surrey County Council and look forward to continue making a positive contribution in the future.'
