A joint venture between Turner Construction Company and Flatiron Construction has been awarded a contract by the City and County of Denver to deliver a $700m expansion of Denver International Airport in the US.

The contract includes the construction of gates, concessions, runways and taxiways at the airport.

Turner Construction Company vice-president and general manager Aaron Wiebelhaus said: “Together with our partner Flatiron, we’re gearing up to streamline and enhance the passenger experience for the more than 58 million travellers who fly to, from, and through Denver every year.

“The contract includes the construction of gates, concessions, runways and taxiways at the airport.”

“Airports help connect people to new places, communities, and experiences. They bring you to the world and the world to you. We look forward to delivering a beautiful facility that will encourage and facilitate that exploration.”

The project will add more than 530,000ft² to Concourse A and 91,000ft² to Concourse B.

As part of the expansion, 16 aircraft gates and two international nodes will be added with provisions for three more, in addition to approximately 384,000ft2 of aircraft-rated pavement.

Flatiron Construction central division vice-president Eric Taylor said: “We are proud to be part of the team expanding and continuing the growth of Denver International Airport.

“We are also glad to be partnering once more with our sister company, Turner, as their vertical construction experience is a strong complement to our heavy civil expertise. Our selection as a joint-venture reflects our past shared success as well as the trust and confidence placed in us by the City and County of Denver.”

Construction is expected to commence this month.
