It’s been a long winter, but we’re seeing signs of spring and optimism around the return of the meetings industry in Seattle. 

After experiencing a coronavirus-induced financing crisis, we confirmed on March 31 the sale of $340 million in municipal bonds to close the financing gap and enable completion of the Addition project. Orders in excess of $3 billion were placed for the $342 million in bonds, a testament to the belief by the bond market in the long-term strength of Seattle and the region.

As of late March, Summit construction is more than 55% complete with 99% of materials purchased, and on track for a mid-2022 opening. Steel work has begun in Zone 5. In the photo below you’ll see the steel decking of the retail space off of 9th Avenue to the left, and the Hillclimb taking shape on the right. Further below you’ll also see a time-lapse video of construction activity through February.

On the operational front, WSCC recently achieved GBAC STAR™ accreditation. Facilities gain accreditation when they show they are implementing the industry's highest standards of cleaning for COVID-19 and are safe to welcome guests and hold events. We’ve implemented these practices in our existing building, Arch, and look forward to applying them in Summit as well.

We greatly appreciate our clients and their resilience. Our staff continues to work remotely, but they are available to answer your questions about booking the Summit and Arch building separately or together as a package. In fact, there are currently over 30 conventions scheduled for Summit from 2022 - 2026.

Questions about booking? Contact our sales team through our website or email.
