Berlogar Stevens & Associates

What Berlogar Stevens & Associates does

Berlogar Stevens & Associates (BSA) is a privately held, full-service geotechnical engineering firm headquartered in Pleasanton, California. The practice traces its origins to 1973, when it was founded as Berlogar, Long and Associates, and has operated continuously for over 40 years, re-establishing under its current name in 2011. BSA delivers integrated geotechnical services across five disciplines: geotechnical engineering (subsurface exploration, foundation design, seismic response analysis, slope stability, dam and levee safety review, pavement design); geology and geologic engineering (fault investigations, landslide evaluation, SMARA reclamation plans); field exploration and testing (Becker hammer, CPT, sonic and mud rotary drilling, seismic refraction surveys); in-house laboratory testing (soil and rock strength, triaxial/direct shear, concrete compression, AC mix designs, R-value/CBR); and construction monitoring with special inspection (earthwork observation, field density, reinforced concrete, structural steel welding and bolting). Inspection staff hold ACI and ICC certifications and are members of the Local 3 Operators union.

BSA serves construction and development clients — including construction companies, developers, and civil engineering firms — across the California Bay Area on a project-by-project, quote-based B2B professional services engagement. GTM is sales-led and conducted primarily via direct phone, email, and a company website (berlogar.com), with no disclosed channel partners, marketing automation, or digital go-to-market infrastructure. The firm operates from a single office at 1220 Quarry Lane, Suite C, Pleasanton, CA, and has no disclosed parent company, subsidiaries, external investors, or funding history. Revenue model is straightforward fee-for-service across each of the four service streams, with all billing tied to project-based engagements.

Broad incumbents

• Terracon Consultants: Terracon is one of the largest US geotechnical, environmental, and materials testing consultancies. It is highly comparable to BSA in core service lines (geotechnical engineering, field exploration, lab testing, special inspection) but operates nationally and at much greater scale, serving as the dominant incumbent peer in this category.
• Kleinfelder: Kleinfelder is a major engineering, geotechnical, and construction services firm offering subsurface exploration, geotechnical engineering, materials testing, and special inspection. It overlaps directly with BSA's full-stack service model and is one of the most direct large-firm comparables for geotechnical work in California and the Western US.
• NV5 Global: NV5 is a publicly traded infrastructure and engineering services provider with strong exposure to geotechnical, environmental, and materials testing. Its California presence and breadth of services make it a relevant competitor and acquirer profile for a regional firm like BSA.
• AECOM: AECOM is a global infrastructure consulting firm that competes in geotechnical engineering and construction services as part of a much broader portfolio. It is comparable as the upper-bound incumbent against which smaller geotechnical specialists like BSA must position for large public-infrastructure work.
• Stantec: Stantec provides geotechnical, environmental, and materials testing services alongside its broader engineering practice. It competes with BSA for mid- and large-scale infrastructure projects where bundled engineering services are required.
• WSP: WSP is a global engineering consultancy with geotechnical and earth sciences capabilities integrated into its infrastructure and environment practices. It competes with BSA on larger, multi-disciplinary projects while overlapping on seismic and geotechnical specialty work.
• GHD: GHD is a global engineering, architecture, and environmental consultancy with geotechnical and materials testing capabilities. It is a relevant competitor on California infrastructure and development work and a comparable profile to other large incumbents relative to BSA's specialist positioning.

Direct peers

• Haley & Aldrich: Haley & Aldrich is an employee-owned geotechnical and environmental engineering consultancy. It is a closely aligned peer to BSA in business model (professional-services consultancy, technically deep, owner-operated) and core offerings in subsurface exploration, foundation engineering, and construction monitoring.
• GeoEngineers: GeoEngineers is a geotechnical and environmental sciences firm with comparable services in geotechnical engineering, field exploration, laboratory testing, and construction observation. Its mid-size, technically specialized profile makes it a close functional analog to BSA.
• Earth Mechanics Inc. Earth Mechanics Inc. is a California-based geotechnical engineering firm with a similar regional, owner-operated profile to BSA. It offers geotechnical engineering, field exploration, and construction monitoring services directly comparable to BSA's core offerings.
