**Section 153. - CONTRACTOR QUALITY CONTROL**

**Construction Requirements**

**153.02 Contractor Quality Control Plan.**

**(a) Process control testing.** [Add the following:]{.underline}

See Table 153-1 for schedule of minimum sampling and testing for process
control. Where no minimums are specified, submit proposed tests to be
performed and the proposed sampling and testing frequencies.

For aggregates and/or aggregate/asphalt mixtures accepted under
Subsection 106.03, sample and test for conformity with the Certification
a minimum of one time per pay item.

**(b) Inspection/control procedures.**

> **(3) Production phase.** [Add the following:]{.underline}
>
> *(d)* Inspect the work, materials or assemblies accepted under
> Subsection 106.03 to ensure that **all** the work and materials comply
> with contract requirements. Furnish the results of the work
> inspection, along with the product certification or commercial
> certification as applicable, to the CO prior to incorporating the
> materials into the work.

**(c) Description of records.** [Add the following:]{.underline}

Identify the format for reporting test results, materials certifications
and the procedures to be used to maintain inspection records.

  -----------------------------------------------------------------------
  On small jobs (i.e. ERFO, OMAD etc), check with the COE regarding the
  need for a QCS that is separate from the Contractor's Superintendent.
  If a separate QCS is not needed, **do not** include the second sentence
  which states; "The QCS will not be the Contractor's Superintendent."

  -----------------------------------------------------------------------

**(d) Personnel qualifications.**

> **(1)** [Add the following:]{.underline}
>
> Designate a Quality Control Supervisor (QCS) whose primary
> responsibility is managing the inspection system. The QCS will not be
> the Contractor\'s Superintendent. Designate a QCS who is experienced
> to perform and supervise all work inspection, sampling and testing.
> The QCS will monitor all phases of the work and identify deficiencies
> and take appropriate corrective action.

[Add the following:]{.underline}

> **(3)** Personnel assigned to sampling or testing will have 1 year or
> more of recent job experience in the type of sampling and testing
> required by the contract, and the following:
>
> *(a)* NICET Level II certification in highway materials, or State
> (SHA) or industry certification-related sampling and testing
> equivalent to their intended responsibilities.
>
> *(b)* WAQTC or other nationally accepted certification program for
> intended sampling and testing responsibilities.
>
> or
>
> *(c)* Current or previous employment by an AASHTO accredited
> laboratory performing sampling and testing equivalent to their
> intended responsibilities.
>
> *(d)* Demonstrated proficiency or successful testing of one or more
> proficiency samples may be substituted for basic qualifications
> pending verification of test results.

**153.03 Testing.** [Delete the title and text and substitute the
following:]{.underline}

**153.03 Sampling and Testing.** Perform the work required by Table
153-1 and by the accepted Quality Control Plan.

**(a) Acceptance sampling.** Acceptance sampling schedules and times or
locations will be provided by the CO. Use a procedure for random
sampling. In addition, sample any material that appears defective or
inconsistent with similar material being produced, unless such material
is voluntarily removed and replaced or otherwise corrected.

**(b) Testing.** If the Government-furnished field laboratory option is
not exercised by the CO, furnish a laboratory equipped with all test
equipment necessary to satisfy the requirements of the contract. Ensure
test equipment has been checked, calibrated, standardized and/or
otherwise verified in accordance with AASHTO and ASTM standards by an
individual qualified to do this work. Ensure mobile laboratories receive
an equipment inspection after the laboratory has been moved to its
permanent location on the project site and anytime it is moved
thereafter. Inspect equipment within 45 days of actual use in project
testing and at least once a year thereafter. Do not use equipment that
has not been inspected or is found to be deficient. Mark deficient
equipment and take it out-of-service until it is repaired or replaced
and shown by subsequent inspection to perform as required. Maintain
records documenting these inspections in the laboratory. Provide
certification(s) stating the equipment conforms to testing requirements
and provide evidence of current inspection.

The CO may require the Contractor to perform testing to demonstrate
acceptable equipment and an acceptable level of technician competence.
The CO may also check equipment and inspection records to verify
condition. Repair or replace equipment not meeting applicable
requirements. Keep laboratory facilities clean and maintain equipment in
proper working condition. Provide the CO unrestricted access to the
laboratory for inspection and review.

**(c) Certifications.** For materials accepted by certification in
accordance with 106.03, review all certifications to insure compliance
with the requirements of the contract prior to incorporating materials
into the work and provide a signed copy of the reviewed certification(s)
to the CO.

**153.04 Records.** [Add the following to the first
paragraph:]{.underline}

When tests are on material being incorporated into the work, report test
results within the reporting times indicated in the sampling and testing
requirements at the end of each section or as specified in the contract.

[Add the following to the second paragraph:]{.underline}

Detailed inspection results including deficiencies observed and
corrective actions taken.

**153.05 Acceptance.** [Add the following:]{.underline}

If chronic deficiencies are noted in the Contractor\'s inspection or
testing systems, the CO may order supplemental inspection and/or testing
to be performed. The Government will charge to the Contractor all costs
associated with such supplemental inspection or testing.

  -----------------------------------------------------------------------
  The Section 153.07 pay item is rarely used. Include Subsections 153.06
  and 07 when there is a bid item for 153. If 154 (Contractor Sampling
  and Testing) is a bid item, do not include subsections 153.06 and
  153.07.

  -----------------------------------------------------------------------

[Delete the text for Measurement and Payment and substitute the
following:]{.underline}

**Measurement**

**153.06** Contractor quality control will be measured by the lump sum.

**Payment**

**153.07** The accepted quantity, measured as provided above, will be
paid at the contract price per unit of measurement for the pay item
listed below that is shown in the bid schedule. Payment will be full
compensation for the work prescribed in this Section. See Subsection
109.05.

The Contractor quality control lump sum will be paid as follows:

(1) 25 percent of the lump sum, not to exceed 0.5 percent of the
    original contract amount, will be paid after all testing facilities
    are in place, qualified sampling and testing personnel have been
    identified, and the work being tested has started.

(2) Payment for the remaining portion of the lump sum will be prorated
    based on the total work completed.
