Construction and Materials Quality Assurance
TRB Circular E-C037 (April 2002) defines Quality Assurance as "All those planned and systematic actions necessary to provide confidence that a product or facility will perform satisfactorily in service." More simply stated, Quality Assurance can be defined as "Making sure the Quality of a product is what it should be."
Various documents such as the National Quality Improvement Task Force Report on QA Procedures for Highway Construction (FHWA DP-89, June 1994) and the AASHTO Implementation Manual for Quality Assurance (February 1996) have outlined six critical elements of a Quality Assurance program. These elements include Quality Control (QC) by the Contractor, Acceptance by the Agency, Independent Assurance (IA), Dispute Resolution, and the use of Qualified Laboratories and Qualified Personnel by both parties.
