Prior to allowing production under a QC program, the district must confirm that the producer's certification is current and that it covers the material being produced. The district must initially, and on a recurring basis, confirm that the producer routinely and diligently follows the requirements of the QC program, and that material produced for MoDOT is specification compliant. This confirmation will be in the form of a quality assurance visit, including a review of all applicable paperwork, a review of the producer’s QC process, and an active inspection of current production (~~a SiteManager~~ plant inspection record is required - 1049XXQCP). When a producer is allowed by the district to produce under a QC program, the producer must agree to notify the district in advance of their intended production schedule. Acceptance of precast concrete box culverts, with MoDOT inspection, is to be based on the inspection of materials being incorporated into the sections, inspection of both the dimensions and the placement of forms and reinforcement, results of compressive tests on cured concrete cylinders or cores, and inspection of the finished pieces.
