General contractor: Lydig Construction

Primary designer: Sclater Partners Architects
The 2020 Fifth Avenue Data Center is located in one of Seattle’s busiest and densest areas.
The project transformed a dated parking garage into a state-of-the-art data center. Work included dismantling the structure’s top three levels, and adding four floors of new construction and two MEP mezzanine levels.
Two stories were excavated below the structure to accommodate fuel storage tanks, transformers and electrical switch gear, water storage tanks, and mechanical and electrical spaces.
To provide sufficient data security, the facility was built to withstand significant seismic events, power outages and extreme weather.
With the project’s dense urban setting, lay-down areas were nonexistent. The project team managed just-in-time deliveries in tandem with the prefabrication of system components and delivered materials vertically through the building, all without disrupting the adjacent properties.
The data center itself is operated from the adjacent Westin Building. To accommodate this critical communication, a fully enclosed steel-and-glass skybridge was installed between the buildings, with additional connections to the Westin garage and the Sixth & Lenora Building.
With 50,482 worker hours the project incurred only one recordable injury. The project is targeting a LEED gold rating.
