Hanson’s geotechnical laboratory accredited by AASHTO

SPRINGFIELD, Ill. – Hanson Professional Services Inc.’s geotechnical laboratory was recently accredited by the American Association of State Highway and Transportation Officials (AASHTO). The AASHTO Accreditation Program (AAP) recognizes Hanson’s competency in construction materials testing and demonstrated proficiency in meeting the minimum requirements set forth by AASHTO. Hanson’s geotechnical services are enhanced by this state-of-the-art, in-house laboratory.

“The certification is a significant accomplishment for Hanson because the U.S. Army Corps of Engineers requires that all geotechnical testing on Corps projects be performed by labs with the AASHTO certification,” says Tracy Lundin, vice president and manager of professional and technical services for Hanson.

Hanson was recently added to the list of commercial laboratories qualified to conduct material tests for the U.S. Army Corps of Engineers and will remain on the list through April 2005. The list can be found at www.wes.army.mil/SL/MTC/mtc.htm under “validated laboratories.”

Hanson’s geotechnical staff tests the engineering properties of geotechnical samples, including triaxial consolidation, unconfined compressive strength and hydraulic conductivity. Hanson is currently performing laboratory tests on projects for the Illinois Department of Transportation, the Burlington Northern Santa Fe Railway Co., the Canadian National Railway Co. and AmerenEnergy Generating Co.
