“We worked together for more than


a year-and-a-half, going through many design iterations and changes, to achieve the final interior permit package,” Abbe noted. “We had over 100 bulletins to avoid any surprises, and as we were issuing new bulletins, we incorporated all of the MEP drawings, which really helped things go smoothly.”


Raising the Bar for Quality Craftsmanship Not only was the interior MEP work created with innovation and precision, DPR’s self-perform craftmanship is on full display throughout the building. DPR self-perform work (SPW) crews


undertook $60 million of trade scope on the project, including all concrete, dry- wall, ceilings, frames, doors and hardware. Self-performing such a large portion of work on the massive concrete structure not only helped control quality, but also improved on-site safety and productivity. To accomplish the poured-in-place


fans programmed to turn on in the event of a fire. Together, they pull over 200,000 cubic feet of air (or smoke) per minute out of the atrium. A trigger to the VESDA smoke detection system or fire sprinkler system in any part of the six-story atrium, automatically opens the operable first floor windows; drops the 60-foot-long level, six-smoke curtain; and shuts me- chanical fire dampers – all while smoke exhaust fans start removing smoke from the air within 30 seconds.

“We conducted several pre-tests to the


system, and the third-party certifier was very impressed that we were able to sign it off in 24 hours to achieve Temporary Certificate of Occupancy,” said Abbe. Effective coordination of the MEP


work, along with strong communication with the owner and design team were critical to a successful outcome. The highly collaborative approach taken by the team and co-location in the Big Room helped drive this success.


concrete work, including the concrete foundation pour, the SPW team carefully coordinated its efforts to work around three other major ongoing projects in the immediate vicinity. Tey scheduled all concrete pours for 1 a.m. to ensure material availability, and simultaneously implemented noise and light mitigation measures to avoid undue disruption to neighboring buildings, which included a UCSF residential facility right next door. As a defining architectural focal point of the building, the SPW concrete work
