About this file
This is a Georgia Department of Transportation (GDOT) materials quality assurance guidance document for Federal-Aid Local Let Projects, establishing the local government responsibilities and procedures for managing materials testing on federally-funded transportation projects. The document outlines three primary options for local governments: requesting GDOT to perform materials testing directly, requesting approval for a consultant to conduct quality assurance testing, or explaining why testing is not required. For projects requiring testing, local governments must submit the OMAT-LAP-1v10 form to the GDOT Project Manager and ensure that only GDOT-certified testing personnel conduct field density testing on embankment, pipe backfill, subgrade, and asphalt layers, as well as concrete testing for any bridge or major structure work. Local governments must notify GDOT's Testing Management Operations Supervisor at least one week prior to asphalt work commencing and provide contact information for certified technicians responsible for roadway and concrete testing.
The document specifies that local governments bear the responsibility for arranging materials testing either through GDOT or by hiring a prequalified consultant with AASHTO-accredited laboratory facilities. All testing must comply with GDOT's Sampling Testing and Inspection Manual and procedures outlined in the GDOT Construction Manual. Local governments must complete and submit quarterly Materials Certificate (MC) Checklists to GDOT's Materials Audit Unit and provide all test results through an approved data collection system or hardcopy format. Independent assurance testing will be performed by GDOT based on technician names submitted on the OMAT-LAP-1v10 form in accordance with GDOT Standard Operating Procedure 30. GDOT maintains regional Testing Management Operations Supervisors across seven districts, with the State Materials Engineer or Assistant State Materials Engineer available at 404-608-4700 for technical guidance and approval of consultant qualifications.
