2003 SPECIFICATIONS

SECTION 106

SECTION 106 CONTROL OF MATERIAL

Section 106 of the Standard Specifications establishes the obligations of the Contractor and the Department concerning materials to be used. The Specifications also provide that materials shall conform to specifications at the time of incorporation in the work. The tests which are the basis of acceptance are those taken at the latest practicable time either prior to, during, or after incorporation into the work. The Contractor has full responsibility for the work until completion and final acceptance.

The Specifications require that the Contractor’s acceptance test results be provided to the Resident by the next business day after the test is performed. Since the contractor’s tests are crucial to determining acceptability of the material, partial payment for pay items involved may be withheld if the test reports are not received in a timely manner.

The Resident Engineer should carefully review the calculations and results of the Contractor’s tests upon receipt. Any discrepancy should be reported to the Contractor and a revised test report submitted. The Resident Engineer shall maintain a Contractor test results file for each project. The Resident Engineer should initial the Contractor’s report and enter the results on a verification form, similar to one of the two versions shown in Figure 106-1 (available on the Materials Division’s directory on the LAN), along with the Department’s verification and acceptance test results. All test reports should be attached to the corresponding verification form.

All field tests, procedures and frequencies shall conform to the instructions contained in the "Manual of Field Sampling and Testing Procedures" published by the Materials Division and the AASHTO Test methods referenced in the Standard Specifications. The "Guide Schedule of Acceptance Testing of Construction Materials" is of particular importance to field personnel.

If at all possible, the Resident Engineer’s materials technician should witness the first contractor acceptance tests. Any discrepancy found in the contractor’s performance should be discussed with the contractor and documented in the job diary. Every effort should be made to observe the initial tests for contractor QC/QA items. Addressing any discrepancies early on should prevent any disputes or questions over material acceptability during full production.
