With luxurious interiors, breathtaking views, and ample amenities, Four Seasons Private Residences at 706 Mission has a lot to offer. Now, it can add LEED Silver® certification to its resume.  

The 47-story, 700,000-square-foot luxury residential project broke ground in June of 2016 and earned its final TCO in December 2020. Several people shared LEED responsibilities over the course of the project's four-year lifetime.

“Our LEED effort was managed by our project engineers and assistant project managers as we rotated the LEED leader position around,” explains Project Director Bill Fish. “Sometimes it was intentional to give people exposure, and sometimes it was out of necessity to get it done.”

Thor Barsness, Dhruv Desai and Nahush Mantadka were a few of the Webcorians who helped lead the process. When reflecting back on the project, Assistant Project Manager Nahush Mantadka recalls that one of the toughest challenges of the process was attaining the Smoke Control credit – an important prerequisite for certification.

“The industry standard is to conduct the blower door test, which is a highly stringent test with a very low success rate (several teams have tried and haven’t had much success),” explains Nahush. “So, we decided to look at other alternatives to gain this credit, one of which was to conduct the tracer gas test, which had a much higher success rate than the blower door test.”

The team was required to submit a formal project credit interpretation request to the USGBC with comprehensive documentation in an effort to approve this alternative testing method.  

“All the coordination and testing happened to coincide with our push for our first TCO, making the process even crazier,” he recalls. Thankfully, the request was approved, the test was conducted, and 706 Mission successfully earned its Smoke Control credit.

Another challenge was rejuvenating the exterior of the historic Aronson building. To help maintain the historical integrity of the building, many bricks were removed, refreshed and re-installed.

“This not only preserved the original character of the building, but also helped with LEED waste diversion as well,” says Assistant Superintendent Thor Barsness.

The project’s noteworthy LEED credits include Development Density and Community Connectivity (SSc2), Water Use Reduction (WEc3), and Construction Waste Management (MRc2).

With a total of 57 points, the team comfortably surpassed the LEED Silver certification threshold of 50 points.

“This is a prime example of how our core values and our focus on building can help enhance the employee experience and protect the planet,” writes Construction Manager Michael Poole. “Congratulations team, and great work on this amazing accomplishment!”
