Federal Lands Highway's Laboratory unless other testing facilities are
authorized by the CO.

Label each concrete mold with the name and number of the Project, the
cylinder number, date molded, location of the sample, and the test age
(i.e. -- 7, 14, or 28 days). Label the mold after casting and the
cylinder after stripping to ensure the sample can be identified
throughout the entire curing process.

  testing. Check with the COE regarding the need for and availability of
  a Government-furnished field laboratory to the project. (Small, short
  duration projects many not warrant a Government trailer). If a
  Government-furnished field laboratory is not available or warranted, do
  not include Section 154.03 A.

> accordance with applicable AASHTO and ASTM standards. The Government
> equipment inspection will be completed after the laboratory has been
> moved to its permanent location on the project site prior to actual
> use in project testing and at least once a year thereafter. Notify the
> CO at least 30 days in advance of intent to use the testing equipment
> on the project so that Government equipment inspection can be
> scheduled and performed. Assume responsibility for additional
> equipment inspections prior to the Government's yearly inspection if
> the mobile laboratory is moved. Maintain records documenting these
> inspections in the laboratory.
>
> Maintain equipment in proper operating condition. Do not use equipment

**154.03B Field Laboratory (Contractor-Furnished).** If the
Government-furnished field laboratory bid option is not exercised,
furnish a laboratory equipped with all test equipment necessary to
satisfy the requirements of the contract.

The sampling and testing services of a commercial laboratory meeting or
exceeding the requirements described herein may be used if all contract
sampling and testing requirements are satisfied by the use of the
commercial facility.

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 it take 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.
