Wallace-Kuhl & Associates (WKA) is Northern California's premier full-service geotechnical, geologic and environmental engineering consulting firm. WKA has earned a reputation for building long-term client relationships and responding to their needs with practical, cost-effective solutions. The success of Wallace-Kuhl & Associates is based on our record of integrity and professionalism. Our team encompasses engineers, geologists, environmental scientists, technicians, and support personnel in our two offices, in West Sacramento and Stockton, California.
Geotechnical engineering constitutes the heritage of Wallace-Kuhl & Associates. Our three founding principals successfully built the company on the foundation of their combined geotechnical experience. Throughout the decades since, WKA has amassed extensive geotechnical experience. Our geotechnical engineers evaluate subsurface conditions and produce critically important analytical information that should be factored into the design of a project before construction of a foundation, slope grading or other ground modifications begin.
The WKA Earthwork Construction Services Department conducts geotechnical engineering inspection and testing during the construction phase of a project. Our exceptional and experienced technicians and inspectors are highly qualified in all aspects of engineered fill construction, roadway and utility improvements, with appropriate CalTrans, NICET and ICC certifications. WKA has an enduring record of diligence and standard-setting performance in borrow source evaluation, engineered fill quality assurance, subgrade compaction testing, foundation excavation inspection, and utility trench backfill inspection and testing.
WKA's Indoor Air Quality Services unit performs scientific analyses of indoor air quality to detect conditions that could be harmful to occupants. The damaging effects of "sick building syndrome" that can occur in sealed offices with poor moisture control have been repeatedly and alarmingly documented. Rectifying sources of airborne contamination to avert the spread of respiratory problems can help clients minimize potential liability. We perform comprehensive air quality analysis for a wide range of structures, including commercial and industrial facilities, educational institutions, medical clinics and hospitals, administrative offices, and residential projects.
