Center 21

A Leed Gold Certified, 9-story, 222,000 square-foot, Class-A office building for Brandywine Realty Trust. The new office tower with below-grade parking, originally known as 2100 Franklin, is positioned adjacent to the 2101 Webster building. The buildings are joined by an enclosed, full-height, elegant sky-lit atrium encased with architectural floor-to-ceiling glass and steel. The combined buildings are integrated to form a new 675,000 square-foot complex known as Center Twenty-One; considered one of Oakland’s largest, premier commercial office complexes and the newest downtown office structure since 2002. This unique architecture incorporates natural light, efficient heating and cooling systems, and 100% recyclable steel construction materials.

At the recommendation of KPFF Consulting Engineers and Charles Pankow Builders, Stearns was brought on board early to provide expert structural steel system and budget solutions, to facilitate the tight coordination of structural design, and administer an aggressive steel construction schedule. In order to achieve these requirements, Stearns predetermined the most appropriate structural steel system and ornamental elements. Their in-house detailing staff took action to develop shop and erection drawings and order materials prior to design completion. Once the design was complete, Stearns managed the fabrication process and delivery sequence to ensure materials arrived at time of installation to maintain the solid critical path agenda. Stearns’ early involvement and proactive approach resulted in immediate commencement from the construction team.

Scott Anderson, Project Executive, Charles Pankow Builders stated: “Stearns proactively managed their responsibilities and Owner requested design changes and enabled Pankow to meet the team’s schedule obligations on a tight urban site.”
