The airport has struck a new partnership with Bechtel, after two years of working together on plans for a second runway and midfield terminal.
The new partnership will see the US company project manage Gatwick’s £9.3bn second runway programme should the government give it the green light.
Architect Sir Terry Farrell has also been working on shaping Gatwick’s vision of a new runway and terminal facility and will work with Bechtel to bring the project to fruition.
Bechtel’s general manager for infrastructure in Europe, Amjad Bangash, said: “We have provided Gatwick with robust plans for a second runway and are confident that this low risk project can be built to the highest quality, safely and sustainably - and that it can be operational by 2025.”
Gatwick Airport chief executive Stewart Wingate said: “Bechtel is a global leader with a strong track record in delivering significant infrastructure projects and we look forward to working together to deliver the UK’s next runway. Gatwick expansion can happen quickly because it is simple and low risk with a dramatically lower environmental impact.”
