Full title and description

Standard Practice for Minimum Requirements for Agencies Engaged in Testing and/or Inspection of Soil and Rock as Used in Engineering Design and Construction — designation ASTM D3740-23. This practice defines minimum qualifications and essential characteristics for organizations that perform geotechnical testing and field inspection of soils and rock, including personnel, facilities, testing capability, and quality-system requirements intended to support evaluation, accreditation, and selection of agencies.

Abstract

ASTM D3740-23 provides a consensus, minimum set of criteria for evaluating testing and inspection agencies that perform soil and rock tests used in engineering design and construction. It addresses minimum qualifications for laboratory and field personnel, organizational and facility requirements, and expectations for a documented quality system. The practice can be used by owners, engineers, and accrediting bodies as a basis for accreditation or qualification of testing/inspection agencies and is intended to be supplemented where project-specific requirements apply.

Scope

This practice establishes minimum qualifications and essential characteristics for agencies engaged in testing and inspection of soil and rock used in engineering design and construction. It defines minimum personnel requirements for field and laboratory staff, outlines quality-system expectations, and provides criteria to evaluate an agency's capability to perform designated tests and inspections. The practice may be supplemented by project-specific criteria and is applicable to standards that reference Practice D3740; to qualify for accreditation under this practice an agency must include at least five standards from ASTM Committee D18 in its accreditation scope. The practice also notes that some requirements may need modification for use outside the U.S.A. and is not a replacement for professional judgment or applicable safety/regulatory requirements.

Key topics and requirements

• Minimum organizational qualifications for testing and inspection agencies, including documented scope of services.
• Minimum requirements and qualifications for field and laboratory personnel and technician certification expectations.
• Facility and equipment requirements to demonstrate capability to perform specified soil and rock tests.
• Quality system and documentation requirements (procedures, records, internal audits, corrective action processes).
• Criteria for evaluating technical capability to perform designated tests and inspections.
• Accreditation-related requirement: agency accreditation scope must include at least five standards from ASTM Committee D18 for qualification under D3740.
• Guidance that the practice may be supplemented for project-specific or regional requirements and does not replace professional judgment or safety/regulatory obligations.

Typical use and users

Used by owners, engineering consultants, geotechnical laboratories, inspection agencies, accreditation bodies, and public agencies to establish baseline criteria when qualifying, selecting, or accrediting organizations that perform geotechnical testing and inspection of soils and rock for construction projects.

Related standards

D3740 references and is used alongside other ASTM standards and practices covering testing methods and accreditation/qualification processes (examples include practices and specifications from Committee D18 such as D5255 for personnel certification, C1077 for concrete testing agencies, D3666 for road/paving materials agency requirements, and E329 for agencies engaging in construction materials testing); users commonly apply D3740 together with specific test method standards referenced in an agency's scope of accreditation.
