Explore the vision, complexity, and execution of one of Seattle’s most iconic developments, Rainier Square. This 58-story, 850-foot-tall mixed-use tower redefined what’s possible in high-rise construction, standing as a bold new landmark in the city’s skyline.

At 1.4 million square feet, Rainier Square integrates retail, office, and residential space in a design that demanded innovation across every phase—from planning to structural engineering to accelerated construction.

This session dives deep into the project’s architectural ambition, logistical challenges, and engineering feats that brought it to life. You’ll hear how the team overcame site constraints, coordinated across disciplines, and delivered the tower an astonishing 10 months ahead of schedule—all while incorporating a new structural system that set a precedent for future construction.
