106.01 Quality of Materials
Only use materials in the Work that conform to all of the Contract quality requirements. Control and incorporate materials to produce completed construction that conforms to and is fully acceptable under t he terms of the Contract. Where reference is made in the Contract to certain manufacturers’ materials or products, it is not the intent to preclude the use of others, but rather to establish minimum acceptable design standards. The Contractor may substitute material and products of other manufacturers provided they are equal to or better than the minimum design standards and are approved by the Department.
106.02 Material Information
When local material reports are available t he Department will provide the Contractor the test report per the specific request. In furnishing such reports, the Department will not be responsible for materials failing to conform to the test reports either as to quality or quantity.
106.03 Local Mat erial Sources
If the Contractor desires preliminary tests of local materials, it shall deliver samples of the materials to the Laboratory. The Department will test one sample (and one referee sample as needed) , and in such t ime as the work load 106.04 59 in the Laboratory may permit. Acceptable test results on preliminary samples will not guarantee acceptance of materials from the same source later.
106.04 Sampling and Testing , or Inspection
Incorporate into the Work only those materials that have been sampled and tested, inspected, and approved by the Engineer. Untested or unaccepted materials used in the Work without the Engineer’s wr itten permission shall be removed and replaced at no cost to the Department. Unless otherwise specified, sampling and testing, or inspection will be conducted by qualified representatives in accordance with the most current published national standard spe cifications, AASHTO or ASTM methods on the date of the Advertisement. Furnish all materials for sampl ing and testing at no cost to the Department. The Department will perform acceptance and verification sampling and testing, or inspection at no expense t o the Contractor . If the Department does not elect to sample and test or inspect at the source, it will sample and test, or inspect, materials after delivery to the site or to the production facility . Furnish all facilities and provide all reasonable ass istance to secure and transport samples, and move materials being inspected. The Departmental procedures will provide sampling and testing frequencies for the acceptance, quality control, independent assurance, verification, or certification for materials and products. The Engineer may accept certain materials or products and assemblies based on Certificate of Compliance signed by the manufacturer or its authorized representative, stating that such materials, products, and assemblies fully comply with the requirements of the Contract. For each lot of such materials or assemblies delivered to the Work, provide a Certifica te of Compliance that clearly identifies the lot. Provide all necessary paperwork with certification submittals as specified in Departmental Procedures. Furnish a notarized Certificate of Compliance for a non -bid item, not permanently incorporated in the Work, but that must meet a designated specification upon delivery of the material to the Project and prior to its being used. The Department may sample and test materials , products, or assemblies accepted on the basis of Certificate of Compliance at any ti me, and may reject such materials and assemblies if found to be in non -conformance with the Contract. 106.05 60 106.05 Source or Plant Inspection The Contractor is entirely responsible for securing satisfactory material. However, if the volume of any given material, the progress of construction, and other considerations of interest to the Department so justify, the Department may inspect materials at the source of supply. The Department will undertake such inspection only when t he Engineer is assured of the fullest cooperation and assistance of the Contractor and of the material producer involved. Provide required copies of all orders, shipping information, and other Procedural Documentation . Provide the representatives of the D epartment with free and safe access at all times to parts of the site or producer’s facility concerning the manufacture and production of material for the Project. If the Contractor is not the owner of the place where fabrication, preparation, or manufact ure is in progress, the plant owner is deemed to be the agent of the Contractor with respect to the obligation assumed hereunder.
106.06 Field Laboratory
Furnish Type A or Type B laboratory(s) or both, as required to be used exclusively for testing purposes. Provide suitable field laboratories or inspection offices at the production facility at which off -site inspection is provided by the Department under 106.05. Locate the laboratory(s) as directed by the Engineer. Install, equip, and make building(s) ready for use before the Contractor’s operations require field testing. All Contractor and producer laboratories must be insp ected and qualified in accordance with TDOT procedures before the Contractor can perform any work.
A.Type A Laboratory consisting of a building, room, or dedicated area having at least 120 square feet of floor area with a minimum width of 8 feet and a minimum height of 7 feet.
