What Strandberg Engineering does

Strandberg Engineering is a privately held structural engineering firm headquartered at 1511 15th Street, San Francisco, California. Founded in 2013, the firm provides a full suite of structural engineering services across the project lifecycle — schematic design, design development, construction document preparation, and construction administration — for projects ranging from high-end single-family residential to large commercial structures. The firm specializes in concrete, steel, and timber-framed structures with particular depth in seismic design relevant to the California market, and is licensed to deliver projects in 12 U.S. states spanning the West Coast, Mountain West, and Southwest.

The firm is principal-led, with four principals (David Strandberg as Principal/Owner, plus Joyce Feng, Benton Lam, and Lars Lee) supported by a team of approximately 25 employees including senior project engineers, project engineers, structural designers, and a BIM drafter. Service delivery is organized across four core verticals: Residential (new construction and remodel), Mixed-Use (multi-family with ground-floor commercial), Commercial (restaurants, wineries, theaters, museums, offices), and Special Projects (public installations and unique structures), with adjunct offerings in feasibility studies, value engineering, and constructability reviews.

The business operates a B2B professional services model, acquiring projects through direct relationships with architectural firms (e.g., 450 Architects, CMG Landscape Architecture, Lundberg Design) rather than competitive bidding or open marketing. Revenue is generated through project-based engagements billed under a quote-based professional services model; no pricing, revenue figures, or financial disclosures are publicly available. The firm is independently owned with no disclosed parent company, institutional investors, or external funding.

Others

• Buro Happold:

Direct peers

• Degenkolb Engineers: San Francisco-based structural engineering firm specializing in seismic design for healthcare, education, and commercial buildings. Highly comparable to Strandberg given shared SF base, seismic domain expertise, and similar mix of new construction and renovation work.
• Tipping Structural Engineers: Berkeley-based structural engineering firm with deep seismic-resilience expertise for residential, commercial, and cultural projects. Closely mirrors Strandberg's California-centric, seismic-focused, mid-sized profile and serves a similar architect-driven client base.
• Forell/Elsesser Engineers: San Francisco structural engineering firm with strong seismic and historic-renovation practice serving academic, civic, and commercial clients. Comparable to Strandberg on geography, seismic specialization, and architect-led project acquisition.
• Holmes Structures: San Francisco-based structural engineering firm working on commercial, residential, and adaptive-reuse projects with significant seismic expertise. Comparable geographic footprint, service mix, and project-type orientation to Strandberg.
• Page & Turnbull (Structural): San Francisco structural and preservation engineering firm serving historic, civic, and cultural projects. Comparable to Strandberg on geography and on the special-projects/cultural-institution segment of Strandberg's portfolio.

Broad incumbents

• Arup: Global engineering consultancy with a San Francisco office providing structural engineering among broader multidisciplinary services. Comparable to Strandberg on project types (cultural, commercial, high-end residential) but operates at far larger scale and scope.
• KPFF Consulting Engineers: Large Pacific-Northwest-headquartered structural and civil engineering firm with offices across the Western US. Operates in the same markets as Strandberg but at significantly larger scale and broader service offering, making it both a competitor for larger projects and a relevant benchmark.
• Walter P Moore: Large national structural and civil engineering firm with West Coast offices serving commercial, sports, healthcare, and cultural projects. Competes with Strandberg for larger commercial and cultural-institution engagements in the Western US.
• Simpson Gumpertz & Heger (SGH): National structural engineering firm with West Coast presence, focused on building structures, enclosures, and resilience work. Provides similar services to Strandberg but at much larger scale and broader geographic reach.
