Construction has begun on a 75,000m² concrete deck at London City Airport.
The huge engineering project is being carried out in King George V dock to create new land as part of the airport’s £480M expansion.
Delivery Partner Bechtel is leading the project alongside main contractor BAM Nuttal, with piling works already underway.
In total over 1,000 piles will be installed to support the deck. Each pile acts as a supporting column, comprising a steel casing with a steel cage inserted and filled with concrete. Each casing is typically 17.5m long and 1.0m to 1.2m in diameter.
After embedding the casing into the dock bed, a further 4m is excavated beneath the base of the casing which is then filled with the cage and concrete.
London City Airport chief development officer Peter Adams said: “The piling and decking phase of the airport development is an incredible civil engineering project, right in the heart of London’s Royal Docks.
“This is the first crucial stage in making London City Airport even better, led by our contractor BAM Nuttall.”
He added: “In essence we’re creating new land to build on, for a new terminal building and parallel taxiway, which will enable more routes, additional airlines and greater choice for passengers.
“Almost anything that you see today will not be untouched by this investment programme.”
The huge £85M two-year project forms an essential first phase of the City Airport Development Programme, estimated for completion in the first half of 2020. The overall programme is expected to be complete in 2022.
