December Newsletter: Peek Inside As The Addition Takes Shape

The Washington State Convention Center (WSCC) Addition (also called Summit) is in its final months of construction. It is a good time for a look inside.

Left: Looking east, the Hillclimb escalators, stairs and seating areas climb from the Flex Hall level to the Ballroom level. Right: Looking west, the Hillclimb descends from the Ballroom level to the Flex Hall level, revealing a view to the Pike Place Market.

The view south to Pine Street emerges under the escalators that form one level of the Addition’s Hillclimb.

Thousands of workers and scores of businesses are bringing the Addition to life. The project has exceeded its diversity goals in a variety of areas and has entered into more than $140 million in contracts with women- and minority-owned businesses (WMBE). From engineers and artists to truckers and designers, the Addition has thus far benefited from the services of more than 110 WMBE businesses. Workforce statistics include 20 percent apprentices, 27 percent workers from Priority Hire ZIP codes, and 32 percent people of color. When open for business, the Addition will be a critical tool for recovery of the region’s hospitality industry, which employs as many as 80,000 people in King County.
