Lumber -- recognized commercial grades only may be used.
Reinforcing Steel -- approximately 900 kg (2000 pounds) per project.
Portland Cement Concrete, (including cement and aggregate) -- not to exceed 15 cubic meters (20 cubic yards) per pour. THIS DOES NOT INCLUDE BRIDGE CONCRETE.
NOTE: Items 1, 2, and 3 above may be accepted by the Resident Engineer on the basis of weight or volume tickets furnished by the Contractor or Supplier and upon verification by the State Inspector that the quantities represented by the tickets are reasonably correct. Materials not shown on the above list or quantities exceeding those shown are NOT to be accepted under this procedure without prior authorization from the State Construction Engineer.
106.18 Acceptance of Portland Cement Concrete. The Department's "Manual of Field Sampling and Testing Procedures” and Subsection 802.06 of the Standard Specifications contain the procedures and requirements for the testing and acceptance of Portland cement concrete and its components (aggregates, additives, and cement).
No concrete plant inspector is required at the concrete plant. Intermittent or random plant inspection may be provided as determined necessary by the Resident Engineer. Under this procedure, arrangements shall be made for the concrete producer to state on the delivery ticket accompanying each load of concrete the class of concrete being furnished, the weights of cement, aggregates and water used in the batch, the time of batching, etc. (Refer to Figure 802-3). For additional information on this, refer to Section 802 of this Manual.
106.19 Maintenance of Records. The Resident Engineer is required to keep the records of materials tests in such a manner that it can be determined where the material covered by any test report was placed on the road and who made the test. These records shall be readily available for inspection at any time.
106.20 Materials Certification. The Resident Engineer is the Department's designated official to verify that all materials are properly documented. The Resident Engineer will examine the files of completed projects to verify that all materials incorporated in the project are properly documented by approved test reports or certifications. The Resident Engineer will then prepare, sign and distribute the Materials Certification as noted below.
On AHTD oversight projects, the Materials Certification letter is to be sent directly to the State Construction Engineer. On FHWA oversight projects, the Materials Certification letter is to be sent directly to the local Division Administrator of the Federal Highway Administration with a copy to the Master Job "D" file. Any exceptions should be noted in this letter (item deductions documented by change orders are not considered as exceptions). A sample format for this letter is shown in Figures 106-4 and 106-5. A copy of the certification should be sent to the Materials Division in either case, FHWA oversight or State oversight.
