Arup, CH2M, Mace and Turner & Townsend have all won bids to work on the £16bn expansion of Heathrow Airport, if the government gives the go-ahead.
The four firms will be Programme Client Partners (PCP).
The Airports Commission last summer recommended that a third runway be built at Heathrow. But rival bids to build a second runway at Gatwick and to expand an existing landing strip at Heathrow remain in the running as the government has delayed a final decision until this summer.
Heathrow director of procurement Ian Ballentine said: “I’m delighted that our client partners are now on board and I look forward to working with them to give the UK a truly world-class, sustainable hub airport. This privately financed, £16bn project will benefit the whole UK as we work to widen the supply-chain right across the nation.”
Arup Group chairman Gregory Hodkinson said: “This strategic appointment to be a key member of the integrated client team builds on our 30 year relationship with Heathrow. As part of the leadership team, we bring extensive cross sector experience of the successful development and delivery of large complex programmes in the UK, as well leading aviation expertise from working with over 100 airports globally. We look forward to working with Heathrow and our fellow partners to fulfil Heathrow’s vision of world-class, sustainable, airport that benefits all of the UK.”
Turner & Townsend chief executive Vincent Clancy added: “We are delighted to be supporting Heathrow in the next phase of their expansion. We are ready to bring our programme management and commercial expertise from airports in over 20 countries to deliver the capacity and global connectivity the UK so urgently needs.
“The Airports Commission has made a clear recommendation and we now need the Government to stop stalling and give Heathrow permission to build an airport of which the country can be proud.”
