Mace has won a key role on the project to build a new stadium for Tottenham Hotspur Football Club.
The contractor was appointed as construction partner for the north London scheme.
Mace will develop pre-construction plans, work on detailed construction programmes and help the club procure specialist sub-contractors.
The 61,000-seater stadium is planned to feature the largest single tier stand in the UK, with 17,000 seats.
Tottenham Hotspur chairman Daniel Levy said: “This is another step towards the delivery of one of the best stadiums in the world.
“We are delighted to have Mace on board. They bring a wealth of experience and I know they share our commitment to ensuring that the development will be first class in every aspect.”
Haringey Council is due to make a decision on a planning application for the scheme next month.A regeneration scheme linked to the new stadium was approved last year.
Mace chief executive Mark Reynolds said: “We are privileged and thrilled to join the team to take the new stadium to its next stage of development. We look forward to working with the club and its consultants to make sure the project is a success. It is of critical importance as it is the flagship development that will act as a catalyst for the regeneration of this area.”
