Seattle-Tacoma International Airport celebrated its most recent construction milestone in December when Turner Construction and Apex Steel guided into place one of the final steel beams atop the expansion project’s highest point. In about 18 months, passengers at Sea-Tac can expect to enjoy a renovated Concourse C nearly tripled in size with a “wish list” of amenities. Those include new dining and retail options and a Pacific Northwest-inspired gathering place anchored by the “tree at C” and even bleachers. “The tree is real wood,” said Janet Sheerer, the capital pro-
gram leader, C Concourse expansion. “That was an important feature. Our design team really wanted to bring the outdoors in. Having that Pacific Northwest sense of place is actually part of our architecture design standard.” The $400 million project will add about 145,530 sq. ft. to the existing 81,000 sq. ft., along with four new stories, raising the concourse building to seven stories and making it the tallest building at the airport. According to the website, “The topping out milestone is commonly celebrated in construction projects around the world and is part of an ancient Scandinavian tradition that celebrates the work and effort of those who worked on construction of the building.” Everyone involved in the project was invited to the cere-
mony and invited to sign the beam, Sheerer said. “Our contractor made a speech about the tradition of the topping out ceremony, which is a really old tradition. The ironworkers were all there, and they’re the ones really celebrating what a major achievement it is for them to get to that highest point on the building,” she said. “So, they put a Christmas tree on it and an American flag on it and raised it by crane to the tippy top point and loaded it into place. Everybody took a little bit of a break and celebrated the milestone, which something we always want to make sure we take the time to do. It was pretty wonderful.” One of the major challenges on the project has been see AIRPORT page 11
