to BD -636M, P ennDOT Design Manual Part 4, Appendix H, and the Pennsylvania Installation Direct Design
to Publication 280. 3.b Plant Acceptance.
3.b.1 General. Do not begin fabrication before the Structural Materials Engineer's inspection and acceptance of the plant. Provide a permanent building offered for the Department's acceptance. Material, equipment, test procedures, methods of fabrication, handling, storage, and transportation are subject to inspection. Through wall lift holes are allowed only if formed during the manufacturing process or cored after the pip e is cured on pipe diameters 42 inches (or elliptical equivalent) and larger . Punch through methods are prohibited on all pipe diameters . Through wall lift holes are prohibited on pipe diameters 36 inches (or elliptical equivalent) and smaller. Register and certify the plant under either the American Concrete Pipe Association (ACPA) or National Precast Concrete Association (NPCA) plant certification program. Submit an annual endorsed copy to the Structural Materials Engineer for continued qualifi cation. 3.c QC.
3.c.1 General. Establish a level of QC based on uniform production practices. Submit the plant's QC Plan and mix design(s) to the Structural Materials Engineer, BDTD, for review and approval. Include with the QC Plan a company organizational chart indicating a separate chain of command from the QC Manager to the Owner/Plant Manager independent of the Production Manager. Resubmit the QC Plan, mix design, and/or organizational chart, when required, due to changes in processes, materials, or personnel. 3.c.2 QC Manager. Provide a QC Manager who has the overall responsibility for the adequacy of production facilities, QC, sampling, and testing, and fabrication of the product, and who will ensure that items are fabricated as designed and specified.
