AGI’s laboratories are equipped to provide the full spectrum of construction materials testing, employing a diverse collection of modern equipment to perform accurate, timely and cost-effective testing. All of AGI’s test equipment is routinely calibrated to national or international standards.

Laboratory testing and equipment calibration are performed in accordance with standards developed by the American Society for Testing and Materials (ASTM), the Association of American State Highway and Transportation Officials (AASHTO), and the Illinois Department of Transportation (IDOT). Routine inspections are performed by State agencies to verify AGI’s excellence in laboratory testing of soil, asphalt, and concrete materials.

AGI has long-standing partnerships with environmental laboratories that hold prestigious accreditations from the National Environmental Laboratory Accreditation Program (NELAP), the National Volunteer Laboratory Accreditation Program (NVLAP), and/or the American Industrial Hygiene Association (AIHA). These relationships have allowed AGI to extend our commitment to accurate, timely and cost-effective analytical services to our clients in all areas of environmental testing.
