Ninyo & Moore Geotechnical and Environmental Sciences Consultants

What Ninyo & Moore Geotechnical and Environmental Sciences Consultants does

Ninyo & Moore Geotechnical and Environmental Sciences Consultants is a privately held professional services firm founded in 1986 and headquartered in San Diego, California, specializing in geotechnical engineering, engineering geology, environmental engineering, hazardous materials consulting, construction inspection and materials testing, geophysical services, forensic engineering, and industrial hygiene. The firm serves public-sector agencies and private developers on infrastructure and construction projects spanning airports, highways, transit, water/wastewater, pipelines, harbors, hospitals, schools, military facilities, and energy infrastructure across multiple U.S. offices. Engagements are delivered via fee-for-service professional consulting, with project work typically performed under direct engagement with owners or as a subconsultant to general contractors, and with senior Principals involved in every project.

The company's revenue model is straightforward professional services billing against project scopes, with pricing not publicly disclosed. It goes to market through direct client engagement supported by industry-association participation (ACEC, ASCE, CMAA, SAME, ULI, and others) and a long-tenured principal-led delivery model that emphasizes continuity and technical quality. Customer concentration is distributed across multiple agencies and geographies, with named engagements including the City of Long Beach, Utah municipalities, Whitaker Construction, and the California Department of Resource and Recycling, alongside a broader portfolio of transportation, water, and education-sector clients. In 2026 the firm joined the SOCOTEC Group as a flagship U.S. platform, retaining its brand identity while gaining access to expanded nationwide technical expertise; the standalone Ninyo & Moore website is scheduled to retire on June 30, 2026.
