Sunset Development
2600 Camino Ramon
Salas O’Brien provided engineering design for mechanical and electrical upgrades to Bishop Ranch’s central plant. Our work empowered the business park’s developer, Sunset Development, to achieve its ambitious goals for sustainability.
Our client
Founded in 1951 and in its third generation of family ownership, Sunset Development is a leading suburban developer in the San Francisco Bay Area. Nestled in the beautiful San Ramon Valley and surrounded by premier dining, shopping, and hotels, Bishop Ranch is one of the company’s premier properties. The cutting-edge business park includes about a dozen buildings with over 10 million square feet of leasable space. Its over 500 tenants include not only larger corporate entities (among them AT&T, Toyota, IBM, and Wells Fargo), but also many small businesses and nonprofits in industries from government, insurance, and marketing to manufacturing, engineering, and retail.
Project highlights

Their challenge
In cooperation with the city of San Ramon, Sunset Development plans to transform the bustling business park into a downtown community hub. As part of these plans for enhancement and expansion, Sunset needed a partner to bring its 2600 Bishop Ranch building up to the company’s high standards for sustainability and efficiency.
Our solution
This project involved a complete refresh of the mechanical system serving the two-million-foot property. Our team completed in-depth mechanical and electrical review and design services that outlined the removal and replacement of the outdated lake based condenser water system and the installation of three new 1,000-ton chillers and supporting infrastructure.
The results
This complex design allowed Sunset Development to reach their ambitious sustainability goals and will support their plans to expand the business park and surrounding area.
