Lagan Construction International has secured a multi-million pound airfield infrastructure project at London City Airport.
Under the project, Lagan Construction will overlay the current runway surface with grooved Marshall asphalt.
The company will also expand the Bravo, Alpha and Charlie taxiways, as well as redevelop the older Kilo, Delta, Lima and Mike taxiways.
The projects are expected to commence in May.
London City Airport CEO Darren Grover said: "The runway overlay is a major project, made more complex by the unique location of our runway surrounded by water on three sides.
"I look forward to working with Lagan Construction International to deliver the programme and future-proof the only runway actually in London."
Other works include the installation of a new pit and duct network, renovation of the existing drainage network, and modernising the current airfield ground lighting (AGL) system to deploy LED lighting.
Lagan Construction International director of International Operations Steve Turner said: "We have a fully committed team to ensure this contract is delivered with the highest safety standards, low environmental impact, within programme and cost requirements."
The company will mobilise its in-house asphalt batching plant and testing laboratories, which are capable of producing 120t of Marshall asphalt each hour.
Expected to be completed in November, the project works will be carried out after airport operating hours to prevent flight disruptions.
