UKIAH, Calif. – LACO Associates has earned accreditation from the American Association of State Highway and Transportation Officials (AASHTO) and acceptance from the Division of the State Architect (DSA) for their Ukiah laboratory located at 311 S. Main St.

In addition to these accreditations, LACO has added several field and laboratory staff members to support the growing demand for construction materials testing and special field inspections, and the Ukiah lab is prepared to serve Mendocino, Sonoma and Lake counties more efficiently and economically than the firm’s Eureka lab.

Mendocino County has only two labs with these certifications, including LACO. There are three certified labs in Sonoma County. LACO’s Eureka lab is one of the only two such labs in Humboldt County.

Both LACO’s Ukiah and Eureka labs are now ready to work on projects for DOT, FHWA, FAA, and numerous local, state, and regional authorities as well as public schools (K-12 and community colleges).

Their capabilities include testing for earthwork, foundations, mix-design reviews, batch plant inspection, concrete sampling, pre-stressed concrete, welding, post-installed anchors, high-strength bolting and fireproofing.

AASHTO accreditation and DSA acceptance demonstrate that the lab rigorously calibrates their equipment and maintains strict quality management systems to support code required construction testing.

LACO provides integrated solutions for development, infrastructure, and geo-environmental projects. The firm has been in business since 1954, and has offices in Eureka, Ukiah and Santa Rosa.

LACO offers engineering, building and site design, planning and permitting, geology and geotechnical, environmental science, materials testing and inspection, survey and drilling services for the North Coast.
