Laboratory Accreditations/Validations

GTX is fully accredited by several agencies including: A2LA, AASHTO/AMRL/CCRL, and GAI-LAP. We are also validated by the US Army Corps of Engineers. We have provided testing services in support of several nuclear power plant projects requiring us to work under an American Society of Mechanical Engineers (ASME) NQA-1 Quality Program - the highest level of QA in our industry.

United States Army Corps of Engineers (USACE) Validation

Validated by the United State Army Corp of Engineers

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

AASHTO Accreditation

The Laboratories of GeoTesting Express are accredited by the AASHTO Accreditation Program (AAP) for the test methods and quality system standards designated on the certificates of accreditation. The AAP utilizes laboratory assessment (on-site audits) and proficiency sample services provided by AASHTO re:source 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 multiple times per year to ensure compliance with appropriate quality and procedural requirements.

American Association for Laboratory Accreditation (A2LA) Accreditation

A2LA Certificate #: 2965.01

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)

Geosynthetics Accreditation Institute

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.

NQA-1 Quality Program

NQA-1 Quality Program

ASME Nuclear Quality Assurance (NQA-1) is a national consensus standard for quality assurance in the nuclear industry. The American Society of Mechanical Engineers (ASME) established the standard as the means to ensure compliance with the requirements of the nuclear industry.
