Seattle-Tacoma International Airport’s $1.5-billion South Concourse Evolution project is advancing toward construction with the selection of Hensel Phelps Construction Co. as the general contractor/construction manager.
The Port of Seattle sent Hensel Phelps a notice of intent to award last month, starting with a preconstruction contract, a company spokesperson says. The port estimates the value of the preconstruction at $8 million and the maximum allowable construction cost contract at $900 million, records show.
