High-End Office Build-Out with Custom Stair and Millwork Integration

Baker Tilly | Silicon Valley Office TI | San Jose, California

DPR delivered a 21,000-sq.-ft Class A office tenant improvement project for Baker Tilly within a high-profile mixed-use development at Santana Row. The project reflected the strength of DPR’s long-standing partnership with Moss Adams and design partner NBBJ, prior to the accounting firm's merger with Baker Tilly. At the time of construction, DPR teams were simultaneously delivering three of the firm's projects nationwide, leveraging shared standards, trusted relationships, and integrated teams to execute seamlessly at scale.

Interconnecting Stair as a Design Focal Point

A custom interconnecting stair served as the centerpiece of the workplace and a defining feature of the project. The stair integrated structural steel, architectural metal, custom millwork and lighting. DPR led a multi-trade BIM and VDC effort with NBBJ to fully coordinate the design and installation, allowing fabrication to proceed without the need for field measurements and ensuring the design intent was achieved with a high level of accuracy.

Working Within an Occupied Space

Installing the stair structure required temporary removal and reinstallation of ceilings and lighting in the occupied tenant space below. Work was carefully sequenced and performed over multiple weekends, with the space fully restored after each phase and no visible impact to occupants. The structural steel components were craned into place from a street behind the mall, lifted over a parking structure, and set through a window opening only slightly larger than the steel itself.

Millwork Design-Assist and Quality Control

The millwork scope evolved into a design-assist effort, with DPR supporting shop drawing development, material selection and quality control throughout fabrication. DPR also managed client vendors, including furniture, AV and security, coordinating across multiple concurrent projects and serving as the client’s on-site representative.

Demolition and Floor Modifications

Creating the curved opening in the existing floor slab added another layer of complexity. The work was carefully sequenced alongside active finish trades and executed with a high level of precision, where even minor inaccuracies would have been visible in the finished space.
