Pearl Place Google Boulder Campus



Thornton Tomasetti is providing structural engineering for a multiphase development, Pearl Place – home of Google’s Boulder campus. Located on a 4.29-acre site, phase one consists of two interconnected buildings totaling 200,000 square feet of Class-A core and shell build-to-suit office space that will enable Google to increase its Boulder workforce from 340 to nearly 1,500 employees.

The four-story, post-tensioned concrete structures feature low floor-to-floor heights to stay within the city’s height restrictions. The campus includes a 12,000-square-foot cafeteria with a full kitchen, an 8,000-square-foot fitness room with showers and lockers, a 4,000-square-foot assembly area for “Tech Talk” programs and two levels of below-grade parking containing 620 spaces.

It also includes a public area with an integrated bike path, and the conversion of a ditch into a flood-control zone. A portion of the below-grade parking extends under the outdoor space requiring pits in the structural framing below to accommodate the trees planted above. Roof setbacks for outdoor terraces on the fourth floor require shallow post-tensioned transfer beams, which are notched to allow for mechanical ductwork.

Phase two will add an additional 130,000-square-foot office building. The campus is designed to achieve LEED Gold certification.
