The new International Arrivals Facility at Seattle-Tacoma International Airport is now estimated to come in at $830M, more than 21% higher than the original estimate of $684M. There’s more bad news too, the latest construction update has the project slated for completion in February 2020, five months behind schedule (so far). The Port of Seattle is blaming contractor Clark Construction for most of the overruns – faulting underestimates and misjudging airport building-code requirements.
If you can’t remember back to the original plan in 2015 or the updates in 2016, The Seattle Times has a nice project summary:
The new International Arrivals Facility (IAF) — a 450,000-square-foot add-on to the current Concourse A in the main terminal building— will double peak international arrival capacity to 2,600 passengers per hour, according to the Port. Arriving international passengers will walk along a new 900-foot-long aerial walkway, 85 feet above the existing airplane taxiway, from the south satellite over the top of Concourse A to the IAF.
