What D&Z Engineering does
D&Z Engineering, Inc. is a private, Cameron Park, California-based structural engineering firm founded in 2004 by Jim Dillingham. The firm provides structural, civil, architectural, and design engineering services across three primary practice areas: commercial projects (office buildings, retail, warehouses, wineries, multi-family residential), residential projects (custom homes, additions, remodels, prefabricated homes, subdivisions, fire rebuilds), and industrial projects (manufacturing facilities, processing plants, material handling systems). Services are delivered as project-based professional services engagements with custom, scope-dependent pricing, and the firm is described as offering comprehensive design capabilities "under one roof" to eliminate the need for multiple consultants.
The firm's core technology stack centers on Autodesk Revit for 3D Building Information Modeling (BIM), and its engineers have developed specialized expertise in concrete structural insulated panels (SIPs) with cementitious skins, prefabricated metal building systems, reinforced concrete, timber framing, and light gauge metal construction. Notable project work includes specialized structural designs such as a rooftop helipad with a lift mechanism and movable sliding roof cover (Aerometals), underground reinforced concrete wine caves (Gwinllan Estate), and custom steel trusses (Firefall Winery), demonstrating capability across non-routine structural challenges. The firm is privately held, founder-operated, and has no disclosed external funding, M&A activity, or institutional ownership.
Customer acquisition is sales-led and direct, sourced through the company's website portfolio, local market reputation in the Sacramento/Sierra Foothills region, and referrals. Named customers span at least eight verticals including aerospace manufacturing, aviation manufacturing, wineries, food processing, healthcare, nonprofit, retail, and real estate development, with the largest disclosed project (Creekside Development) covering 46,000+ sq-ft of multi-building design. The firm coordinates with external geotechnical, MEP, and metal building specialists as needed, and has established a core architectural partnership with Thompson Naylor Architects, Inc.
