Airports are the busiest construction market almost nobody talks about. U.S. large-hub capital programs run an estimated $130 to $140 billion in 2026, and terminal work specifically is hitting record levels. The buildings are big, the schedules are brutal, and almost all of it happens while planes keep landing.
The marquee jobs stack up fast. Chicago just handed out the $8.5 billion O’Hare Global Terminal contract. DFW is midway through its $12 billion DFW Forward plan, adding a new Terminal F and rebuilding Terminal C. JFK is opening gates at its $19 billion New Terminal One and its $4.2 billion Terminal 6.
Not just the giants
The mid-size hubs are spending too. Tampa’s Airside D runs $1.3 billion, Nashville’s new Concourse D $1.4 billion, and Denver’s Great Hall renovation $1.8 billion. Raleigh-Durham has $2.5 billion of runway, terminal and parking work in delivery. Passenger growth and aging 1970s-era terminals are pushing every large hub into the same cycle at once.
The common challenge
These jobs share a delivery model and a headache. Design-build to compress schedules, phased around live operations, with baggage systems and security zones that can’t go dark. The O’Hare Global Terminal is the template: demolish and rebuild a central terminal without closing the airport. Get the phasing wrong and the whole program slips.
