This project consists of the construction of a 284 unit apartment complex (approximately 270,000 SF) on top of an existing 3-story concrete structure located in Emeryville. Project features exterior courtyards with landscaping and a swimming pool. The existing concrete structure has two levels of parking with retail shops at the ground level. Construction of the apartments did not disrupt the retail businesses because scaffolding will be held off the ground. The apartments are framed with a proprietary steel tube panelized wall system that supports all gravity and lateral loads while floors are framed with metal joists, plywood and concrete fill.

Previous John Castagnoli Vice President of Construction John Castagnoli grew up in the Bay Area learning about the construction industry and Devcon from his father and grandfather who owned a local design-build HVAC firm. “I was able to watch first-hand how HVAC systems were designed, bid, and built and how those systems were incorporated into buildings. I realized at an early age that my passion was to work on large construction projects and set a goal to work at Devcon Construction based on the company’s leadership, culture, integrity, industry reputation, and unique design-build capabilities,” Castagnoli recalled. After graduating from Colorado State University with a Bachelor of Science in Civil Engineering, Castagnoli returned to the Bay Area earning a Master of Science in Structural Engineering from Stanford University and started at Devcon as a Project Engineer in 2001. He was promoted to Project Manager in 2005, Project Executive in 2014, and his current position of Vice President in 2019. While at Devcon, Castagnoli has managed a wide variety of project types including commercial office campuses, a five-star hotel, computing labs, a medical research facility, a downtown high-rise office tower, data center expansions, multiple parking structures, and infrastructure improvements. As Vice President, his responsibilities include serving as the client contact, providing pre-construction and estimating services, design management, scheduling projects for maximum efficiency, and project cost controls. Castagnoli led the 1212 Bordeaux project which was awarded the National Award of Excellence from the Design-Build Institute of America and received seven separate awards for design, construction process improvements and sustainability and the 1400 Page Mill Road project which achieved Net-Zero electric and received eight awards for architecture and energy performance. “I am driven every day by the opportunity to work with the incredible architects, project management teams, and field crews at Devcon to design and build aspiration projects for our clients including Net-Zero Electric, LEED Platinum, Living Building Challenge, Net-Zero Carbon, and Progressive Design Build Campuses.” Next
