United States Army Corps of Engineers (USCOE) Validation
The U.S. Army Corps of Engineers Research and Development Center's Materials Testing Center (MTC)
inspects GTX's laboratories once every two years for compliance with Engineer Regulations 1110-1-8100
(Laboratory Investigations and Testing) and 1110-1-261 (Quality Assurance of Laboratory Testing Procedures)
American Association of State Highway and Transportation Officials (AASHTO) Accreditation
The AASHTO Accreditation Program (AAP) recognizes the competency of GeoTesting Express' laboratories
in construction materials testing. The AAP utilizes laboratory assessment (on-site audits) and proficiency
sample services provided by the AASHTO Materials Reference Laboratory (AMRL) and the Cement and Concrete
Reference Laboratory (CCRL) for accreditation. GTX's laboratories are audited once every two years and
participate in the proficiency testing program twice per year to ensure compliance with appropriate
quality and procedural requirements.
American Association for Laboratory Accreditation (A2LA) Accreditation
The American Association for Laboratory Accreditation (A2LA) has accredited GeoTesting Express' Massachusetts
laboratory in the field of geotechnical testing. Our accreditation is based on internationally recognized
criteria for competent laboratories: ISO/IEC 17025:2005. A2LA performs scheduled on-site audits of
our laboratory and requires us to enroll in a proficiency test program. The Nuclear Regulatory Commission
(NRC) recognizes A2LA accreditation as an acceptable means of qualifying calibration laboratories
Certificate #: 2965.01
Geosynthetics Accreditation Institute - Laboratory Accreditation Program (GAI-LAP)
The GAI-LAP program certifies that GTX is capable of properly rendering the tests that we are contracted
to perform. GTX's equipment, documentation and testing protocols are evaluated for adherence to standardized
test methods. Our lab is audited once every five years and is enrolled in a yearly proficiency test program
to ensure compliance with requirements.
Massachusetts Concrete Testing Laboratory License
Laboratories performing testing of concrete for use in buildings and other structures in Massachusetts are
required (by the State Building Code) to hold a license with the state renewable on an annual basis.
The Board of Building Regulations and Standards (BBRS) issues this license. This program exists to ensure
that laboratories performing tests on concrete are qualified to do so.
Foreign Soil Entry Permit
GTX is licensed by the United States Department of Agriculture (USDA) to receive soil samples from outside the United States.
