Quality Assurance Stewardship Activities

A revision of FHWA's sampling and testing regulations titled, "Quality Assurance Procedures for Construction", was published on June 29, 1995 as Title 23, Code of Federal Regulations, Part 637 (23 CFR 637). The regulations require each State Agency to have in place an approved Quality Assurance (QA) Program for materials used in Federal-aid highway construction projects. Provided certain checks and balances are in place, the regulations provide flexibility in sampling and testing by allowing the use of Contractor test results in the overall Agency acceptance decision. In addition, consultants may be used in performing Dispute Resolution or Independent Assurance (IA) if the laboratories have been AASHTO accredited. The States may also use a system approach to IA instead of establishing frequencies based on individual project quantities.

The regulations also add several additional requirements. They include: (1) the State Agency's central laboratory was required to become accredited by the AASHTO Accreditation Program by June 30, 1997 and, (2) all testing personnel and laboratories must be qualified using State procedures by June 29, 2000.

The reviews are part of the Federal Highway Administration overall stewardship activities for State Agency QA Programs.
