About Kleinfelder

The Kleinfelder Group isn't afraid to get its hands dirty. Since its start as a materials testing lab in 1961, the company has expanded to become one of the largest engineering consulting and design groups in the US. Kleinfelder's operating subsidiaries offer soils and materials testing, geotechnical engineering, construction management, and environmental – more... services. With about 50 domestic offices and locations in Australia and Guam, the group targets the energy, transportation, water, commercial/industrial, government, and education markets; projects run the gamut from building underground parking garages to establishing wind farms. Jim Kleinfelder, who retired in 1993, founded the employee-owned company.

Geographic Reach

Kleinfelder has operations in the US and Calgary, Canada. It opened offices in Australia and Guam in 2010.


Kleinfelder is expanding at home and abroad though organic growth and frequent acquisitions of environmental services firms. It entered Canada in 2012 with an office in Calgary and continued its expansion in Australia (begun in 2010) with a pair of acquisitions there.

In 2011 the firm introduced a program to certify greenhouse gas emissions to help clients remain compliant in clean air regulations. Two years earlier, it launched a nuclear services division to serve the uranium mining and milling, power generation, and spent-fuel storage sectors.

Mergers and Acquisitions

In 2012 Kleinfelder acquired two Australian environmental services firms: Ecobiological Group, and Alliance Environmental Engineering and Consulting Pty Ltd.. The twin purchases strengthen Kleinfelder's position in the retail petroleum assessment and remediation market there, and help the company grow its multinational client list throughout Australia and the Asia-Pacific Region.

Closer to home, Kleinfelder in 2013 purchased Simon Wong Engineering (SWE), a San Diego-based firm providing project management, structural and bridge engineering services, construction management and  inspection services, and public relations support to the transportation and water markets in California to strengthen its resources to serve its global clients. The SWE purchase followed two domestic acquisitions: Omni Environmental in Princeton, New Jersey, and Houston-based Corrigan Consulting, in 2012. In 2011 it purchased InSite Environmental in Stockton, California.


The Kleinfelder Group is owned by its employees. – less
