(A) The quality of materials and workmanship on a project must conform to the contract specifications so that the public funds expended will have purchased a safe, economical and fully functional purpose. The DOE must make arrangements to provide for and administer a materials management process. Manufacturers, suppliers, contractors or ODOT certifications as sole documentation of acceptability are not always sufficient. The acceptability should be consistent with the specifications and may require independent assurance testing.
(B) The DOE through its CE is responsible for material testing and inspection pursuant to the minimums listed below and as described in the project’s approved materials management process. The DOE’s proposed materials management process shall be submitted by the CE prior to being finalized at the pre-award meeting. Approval is contingent on meeting or exceeding the minimum standards listed below and the intent of the plans and specifications. In addition, the materials management process should list the individuals responsible for testing and inspection, their certifications and those of an independent testing laboratory to be utilized. Only laboratories certified by AASHTO Materials Reference Laboratory (AMRL) for the materials to be tested are permitted.
(C) Reimbursement of federal/state funds may be denied for materials incorporated into the work without or contrary to the accepted materials management process and contract documents.
(D) FHWA does not require specific testing and inspection of materials off the NHS (National Highway System). However, ODOT does require testing and inspection of materials on all projects no matter the highway designation. This requirement is being passed to the DOE by accepting federal and/or state funds. In order to protect the interest of public safety and to protect the city from receiving substandard materials, the following minimum standards are required. For all DOE administered projects that exceed $2,000,000 of federal and/or state funds, all ODOT materials testing and inspection standards and requirements are to be enforced. The minimum standards that follow apply only to those projects less than $2,000,000.
(E) All materials not specifically listed below, must be supplied by certified ODOT suppliers. The contractor will notify the DOE of the start date of the project, a minimum of three days before actual work begins:
(1) Aggregate, to be provided by a certified ODOT supplier;
(2) Asphalt concrete production and testing will be performed according to ODOT Supplement 1056. Simply stated, all asphalt concrete specified in plans will be ODOT item 448. All asphalt concrete supplied will be from ODOT approved Job Mix Formulas (JMFs). As part of ODOT’s quality assurance procedures, ODOT will perform periodical plant testing and monitoring of asphalt concrete production. Forty-eight hours before significant asphalt concrete production is to begin, the contractor shall notify the DOE so that plant monitors are available and aware of the JMF to be used;
(3) Portland cement concrete for paving will be batched from an ODOT approved concrete plant, delivered to the project site in an ODOT inspected mixer, from an ODOT approved Job Mix Formula (JMF) and according to ODOT Supplemental Specification 899. For each day’s pour, air, slump, temperature and yield tests shall be taken for each 50-100 yards of delivered concrete. A beam tensile test shall be performed to represent that day’s production. Further testing and quality control requirements are found in the ODOT Manual of Procedures for Concrete. The individual performing the tests shall be ACI Level I Field Technician certified. Forty-eight hours before significant concrete production is to begin, the contractor shall notify the DOE so that plant monitors are available and aware of the JMF to be used;
(4) Miscellaneous portland cement concrete, concrete will be batched from an ODOT approved concrete plant, delivered to the project site in an ODOT inspected mixer, from an ODOT approved Job Mix Formula (JMF) and according to ODOT Supplemental Specification 899. Each 50 yards of delivered concrete, or fraction thereof, air, slump, temperature and yield tests shall be taken and one set of cylinders made according to the ODOT Manual of Procedures for Concrete;
(5) Miscellaneous materials, such as guardrail, pipe, catch basins, manholes, signs, posts, lighting fixtures and the like shall be provided by a certified ODOT supplier and field inspected for defects prior to incorporation into the project;
(6) Small quantities, with the written approval of the CE, non-tested portland cement concrete and asphalt concrete materials may be incorporated into the project, from ODOT certified suppliers provided the quantity is less than 50 cubic yards;
(7) Structures, minimum requirements are as follows:
(a) Two test cylinders, made of the concrete incorporated in each day of work, will be made from each 200 cy (150 m3) or fraction thereof, on structures over 20 feet clear span (6.1 m), as per § 511 of the Construction & Material Specifications (C&MS);
(b) Two test cylinders, made of the concrete incorporated in each day of work, will be made from each 50 cy (35 m3) or fraction thereof, on structures 20 feet clear span (6.1 m) or less, as per § 511 of the C&MS;
(c) When necessary to permit early removal of false work or to permit backfilling, a concrete test beam shall be made and tested in accordance with Supplement 1023, as per Specification 511 of the C&MS;
(d) Air, slump and yield tests shall be performed on the first several loads of each day’s production of concrete to ensure the concrete meets the required specifications and to ensure the proper adjustments have been made to bring the concrete into the required specifications, as per § 704.1.2 of the Manual of Procedures for Structures;
(e) Following the initial testing, concrete for substructures shall have air, slump and yield tests performed as often as necessary to assure the required specifications are met, as per the Manual of Procedures for Structures;
(f) Following the initial testing, concrete for superstructures shall have an air test completed on each load of concrete. Slump and yield tests shall be performed as often as necessary to assure the required specifications are met, as per the Manual of Procedures for Structures;
(g) Each time test cylinders or test beams are made, an air, slump and yield test shall also be performed; and
(h) For structural members, steel members, pre-stressed concrete box and I-beams shall be from ODOT certified producers.
(8) For any materials neither listed above nor available from ODOT certified suppliers, the appropriate testing, sampling and inspection requirements will be as submitted and approved in the materials management process.
