A Seattle-based cancer treatment and research center is expanding to better serve patients and their families while enhancing the way cancer is treated. The expansion adds an adjacent six-story building with 130,000 square feet of a space for highly specialized patient care programs and associated support spaces. A three-level below-grade parking garage will feature a robotic automated parking system—the first of its kind for any medical center in the Puget Sound region and the first of its size on the West Coast.

Approach Spotlight

Parking Innovation

The garage footprint is long, narrow, and tall. GLY proposed the idea of using an automated parking system [APS] to make efficient use of the compact space, reduce the overall size of excavation, and provide a better patient parking experience. This APS will be the first of its kind for any medical center in the Puget Sound region, and the first of its size on the West Coast.

Navigating City Codes

GLY and ZGF successfully managed to help the client avoid a costly substantial alteration. The design started as a full tie-in to the existing building—connecting at two locations on each of seven floors. This required replacing incoming radial power with network power, connecting the fire sprinkler systems, and connecting below-grade parking garages. This triggered a substantial alteration through City of Seattle, resulting in extensive upgrades to meet current codes. After negotiation attempts with the City, GLY budgeted various scenarios and revisions to the existing clinic to find a balance of code upgrades, programming, and aesthetics that met the project goals.

Modular MRI Building

As part of this expansion project, GLY collaborated with ZGF Architects, Modular Resources, and many others on a one-story, 2,300 square foot prefabricated building to house MRI services. While the new tower expansion will feature four new MRI rooms to better serve patients, the client communicated the need for at least one additional MRI sooner than the tower’s completion date. The project was a perfect candidate for the prefabrication of the full building module, limiting on site work to site and foundation prep.

GLY has been exemplary to work with. Their focus on safety, maintaining schedule/budget, prioritizing efficiencies, engaging in pro-active communication, and delivering top notch customer service rooted in collaboration throughout the entire process is an owner’s dream come true.
