Intuit’s Marine Way Building
In the heart of Silicon Valley, Intuit, creator of Turbo Tax and QuickBooks, has a new kind of workplace. As part of the company’s headquarters, the new Marine Way Building (MWB) provides a sustainable, healthy, and interconnected work environment for Intuit. The four-story, LEED Platinum commercial office building has an array of amenities over its 185,400 square-feet—including one story of below-grade parking, a vast all-hands atrium space, “hanging” conference rooms, feature stairs, numerous terraces, and a green roof.
The post-tensioned concrete office building is unique in its trapezoidal shape, numerous large cantilevers, and 60-feet x 90-feet all-hands atrium space. To realize the architect’s desire for a flat soffit upturned beams were provided, where necessary, and to accommodate the 12-feet typical and up to 27-feet cantilevers on all sides of the building, careful implementation of post-tensioning was used in conjunction with cracked long-term deflection analyses. To meet the client’s desire for an open all-hands space, Holmes Structures implemented a 90-ft concrete encased steel truss, that supports the upper two stories of building, and allows for a column-free atrium space. Holmes Structures had to consider the constructability of the truss details as well as construction sequencing to ensure its successful installation. Holmes Structures also engineered a distinct blue feature stair that climbs across the atrium to connect three levels, improving the building’s circulation. Additionally, Holmes Structures accommodated discontinuous columns at the first floor with large (four-foot wide, three-foot deep) transfer beams; these allowed space for the necessary drive aisles below at the basement parking level.
This presentation will highlight the structural challenges for this project as well as highlight the lessons learned.
