We’re now 18 months into construction and things are starting to take shape!

You may notice something interesting, with structural steel erection underway: Instead of a traditional, bottom-to-top approach, the team is constructing Summit from east-to-west, resulting in a shorter construction duration. You can see evidence of this in the annotated photo below.

The method, called “billboarding,” involves structural steel rising in one of five geographic zones at a time. Each zone will top out at full height as the next zone’s steel erection begins. This approach simplifies logistics and improves workflow.

Also below is a time-lapse video capturing construction activity from August 2018 through December 2019. It offers an interesting look at a building in the making and the ever-changing seasons of Seattle, proving that it doesn’t always rain in Seattle.

Summit is scheduled to open for business in the Spring 2022. While construction will be complete in 2021, our teams will need time for the commissioning of systems, furniture and fixture installations, and final preparations to welcome our guests.

Meeting Planners: Bookings for Summit are underway! Whether you book the Summit and Arch buildings together as a package or separately, you will experience the same level of excellence you’ve come to expect from us. Additionally, we are excited to welcome the Hyatt Regency Seattle, a new headquarters hotel, with 1,260 rooms located just north of Summit.
