DeSilva Gates Construction

DeSilva Gates Construction is a general engineering contractor based in Alameda, California, working on large-scale infrastructure projects across Northern California. Founded in 1930 by Oliver de Silva, it began as a small grading and paving operation with a single Michigan scraper and has operated for more than nine decades. Its work covers civil engineering construction, grading, paving and construction management.

The company's operations are supported by assets of direct interest to diesel and heavy-equipment technicians. It owns and operates three hot-mix asphalt plants supplying paving materials, and runs one of the largest aggregate facilities in Northern California. Keeping these plants, mobile equipment and hauling fleets running is central to its self-supply of materials and to its project delivery.

Projects span residential and commercial development, public works and transportation agencies, and aviation. Its portfolio includes roads, water systems, housing, workplaces and transportation infrastructure.

DeSilva Gates describes itself as a multi-generational, family-rooted business. It cites a tradition of service passed between generations, an emphasis on knowledge sharing and mutual respect, and a principle of demanding the best of its team as the basis for its results. The company is award-winning.
