Section 154 — Contractor Sampling and Testing

Description

154.01This work consists of obtaining samples, testing, and reporting the required test results. It excludes Contractor process and QC sampling and testing required under Section 153.

Construction Requirements

154.02General. Sample and test material according to the Sampling, Testing, and Acceptance Requirements tables included at the end of each Section. Provide testers conforming to Subsection 153.02(d) . Perform additional sampling and testing as directed if material does not meet requirements. Provide the CO the opportunity to witness sampling, splitting, and testing of material. Where process control sampling and testing frequencies are identical to the sampling and testing frequencies for acceptance, the process control samples may be used for acceptance for the applicable work.

154.03Sampling. Sample and split samples according to AASHTO or other acceptable procedures. For statistical acceptance samp ling, the exact location of sampling will be determined by the CO based on random numbers. Perform splits when required and deliver the Government’s portion of the sample or split sample in an acceptable container suitable for shipment. Label samples with the following:

(a)Project number and name;

(b)Pay item number and description;

(c)Source of material;

(d)Sample number;

(e)Date sampled;

(f)Time sampled;

(g)Location sample taken;

(h)Name of person sampling;

(i)Name of person witnessing sampling; and

(j)Type of test required on sample.

154.04Testing. Conform to Subsection 153.07 for sampling and testing. Demonstration of testing competence may be required.

154.05Records. If tests are on material being incorporated in the work, report test results within 24 hours unless otherwise specified in the Sampling, Testing, and Acceptance Requirements tables. Report test 74 results on forms containing sample information required by Subsection 154.03. Label interim measurements used to determine the results. Attach worksheets used to determine test values to the test result forms. Payment for work may be delayed or the work stopped until test results are submitted.

154.06Acceptance. Contractor sampling and testing will be evaluated under Subsections 106.02 and

106.04based on Government verification testing.

Measurement

154.07Measure the Section 154 pay items listed in the bid schedule according to Subsection 109.02 .
