Seattle Great Wheel | Seattle, WA

Jackson | Main Architecture, P.S. (JMA) provided architectural design services in support of the Seattle Great Wheel, a landmark waterfront attraction extending approximately 40 feet over Puget Sound and offering panoramic views of Seattle. The wheel features 42 climate-controlled gondolas and accommodates up to 252 passengers at full capacity.

To support the installation of the Great Wheel, Pier 57 required substantial structural reinforcement. The project included the design of a custom elevated mat foundation supported by more than 50 galvanized steel piles, each approximately 3 feet in diameter and extending 100 feet below the water’s mud line. The piles were filled with reinforced concrete, and the mat foundation was structurally isolated from the existing pier with a 12 inch seismic separation to address seismic performance requirements.

JMA’s scope also included the design of supporting guest infrastructure, including ticket booths, a covered loading platform, and escalators connecting riders to the adjacent food court. Together, these elements support safe operation, efficient circulation, and a cohesive visitor experience for one of Seattle’s most recognizable waterfront destinations!
