HomeMy WebLinkAboutQuality Assurance ProgramQUALITY ASSURANCE PROGRAM (QAP)
CITY OF NATIONAL CITY
The purpose of this program is to provide assurance that the materials incorporated into the
construction projects are in conformance with the contract specifications. This program should be
updated every five years or more frequent if there are changes of the testing frequencies or to the
tests themselves. To accomplish this purpose, the following terms and definitions will be used:
DEFINITION OF TERMS
• Acceptance Testing (AT) — Sampling and testing, or inspection, to determine the degree of
compliance with contract requirements.
• Independent Assurance Program (IAP) — Verification that AT is being performed correctly by
qualified testers and laboratories.
• Quality Assurance Program (QAP) — A sampling and testing program that will provide
assurance that the materials and workmanship incorporated into the construction project are
in conformance with the contract specifications. The main elements of a QAP are the AT, and
IAP.
• Source Inspection — AT of manufactured and prefabricated materials at locations other than
the job site, generally at the manufactured location.
• QAP Manual — Quality Assurance Program Manual for local agencies which provides quality
assurance guidelines for materials used in Federal Aid Projects.
MATERIALS LABORATORY
The City of National City will use a private consultant materials laboratory to perform AT on
Federal -aid and other designated projects. The materials laboratory shall be under the responsible
management of a California registered Engineer with experience in sampling, inspection and
testing of construction materials. The Engineer shall certify the results of all tests performed by
laboratory personnel under the Engineer's supervision. The materials laboratory shall contain
certified test equipment capable of performing the tests conforming to the provisions of this QAP.
The materials laboratory used shall provide documentation that the laboratory complies with the
following procedures:
1. Correlation Testing Program — The materials laboratory shall be a participant in one or
more of the following testing programs:
a. AASHTO Materials Reference Laboratory (AMRL)
b. Cement and Concrete Reference Laboratory (CCRL)
c. Caltrans' Reference Samples Program (RSP)
2. Certification of Personnel — The materials laboratory shall employ personnel who are
certified by one or more of the following:
a. Caltrans District Materials Engineer
1 of 4
b. Nationally recognized non-Caltrans organizations such as the American Concrete
Institute, Asphalt, National Institute of Certification of Engineering Technologies,
etc.
c. Other recognized organizations approved by the State of California and/or
Recognized by local governments or private associations.
3. Laboratory and Testing Equipment — The materials laboratory shall only use laboratory
and testing equipment that is in good working order. All such equipment shall be
calibrated at least once each year. All testing equipment must be calibrated by impartial
means using devices of accuracy traceable to the National Institute of Standards and
Technology. A decal shall be firmly affixed to each piece of equipment showing the date
of the last calibration. All testing equipment calibration decals shall be checked as part of
the IAP.
ACCEPTANCE TESTING (AT)
AT will be performed by a materials laboratory certified to perform the required tests. The tests
results will be used to ensure that all materials incorporated into the project are in compliance
with the contract specifications.
Testing methods will be in accordance with the California Test (CT) Methods or a national
recognized standard (i.e., AASHTO, ASTM, etc.) as specified in the contract specifications.
Sample locations and frequencies may be in accordance with the contract specifications. If not so
specified in the contract specifications, samples shall be taken at the locations and frequencies as
shown in Attachment #1, Appendix D, "Acceptance Sampling and Testing Frequencies" of the
QAP Manual.
INDEPENDENT ASSURANCE PROGRAM (IAP)
IAP shall be provided by personnel from Caltrans, the Agency's certified materials laboratory, or
consultant's certified materials laboratory. IAP will be used to verify that sampling and testing
procedures are being performed properly and that all testing equipment is in good condition and
properly calibrated.
IAP personnel shall be familiar with all required testing procedures, as part of IAP, and shall not
be involved in any aspect of AT.
IAP shall be performed on every type of materials test required for the project. Proficiency tests
shall be performed on Sieve Analysis, Sand Equivalent, and Cleanness Value tests. All other
types of IAP shall be witness tests.
Poor correlation between acceptance tester's results and other test results may indicate probable
deficiencies with the acceptance sampling and testing procedures. In cases of unresolved
discrepancies, a complete review of AT shall be performed by IAP personnel, or an independent
materials laboratory chosen by the Agency. IAP samples and tests are not to be used for
determining compliance with contract requirements. Compliance with contract requirements is
determined only by AT.
2 of 4
REPORTING ACCEPTANCE TESTING RESULTS
The following are time periods for reporting material test results to the City:
• When the aggregate is sampled at material plants, test results for Sieve Analysis, Sand
Equivalent and Cleanness Value should be submitted to the Project Engineer within 24 hours
after sampling.
• When materials are sampled at the job site, test results for compaction and maximum density
should be submitted to the Project Engineer within 24 hours after sampling.
• When soils and aggregates are sampled at the job site:
(1.) Test results for Sieve Analysis, Sand Equivalent and Cleanness Value should be
submitted to the Project Engineer within 72 hours after sampling.
(2.) Test results for "R" Value and asphalt concrete extraction should be submitted to the
Project Engineer within 96 hours after sampling.
When sampling products such as Portland Cement Concrete (PCC), cement -treated base (CTB),
hot mix asphalt (HMA), and other such materials; the time of such sampling shall be varied with
respect to the time of the day insofar as possible, in order to avoid a predictable sampling routine.
The reporting of AT results, if not performed by the agency staff, shall be done on an expedited
basis such as by email, fax or telephone.
TESTING OF MANUFACTURED MATERIALS
During the Design phase of the project, the Project Engineer may submit a "Source Inspection
Request" see Attachment #2, Exhibit 16-V of the Local Assistance Procedure Manual (LAPM),
to the Agency, consultant, or Caltrans for inspection and testing of manufactured and
prefabricated materials by their materials laboratory. A list of materials that can be typically
accepted on the basis of certificates of compliance during construction is found in Attachment #3,
Appendix F of the QAP Manual. All certificates of compliance shall conform to the requirements
of the contract specifications, for examples see Attachment #4, Appendix J of the QAP Manual.
Should the Agency request Caltrans to conduct the source inspection, and the request is accepted,
all sampling, testing, and acceptance of manufactured and prefabricated materials will be
performed by Caltrans' Office of Materials Engineering and Testing Services. For Federal -aid
projects on the National Highway System (NHS), Caltrans will assist in certifying the materials
laboratory, and the acceptance samplers and testers. For Federal -aid projects off the NHS,
Caltrans may be able to assist in certifying the materials laboratory, and the acceptance samplers
and testers.
PROJECT CERTIFICATION
Upon completion of a Federal -aid project, a "Materials Certificate" shall be completed by the
Project Engineer. The Agency shall include a "Materials Certificate" in the Report of
Expenditures submitted to the Caltrans District Director, Attention: District Local Assistance
Engineer. A copy of the "Materials Certificate" shall also be included in the Agency's
construction records. The Project Engineer in charge of the construction function for the Agency
shall sign the certificate. All materials incorporated into the work which did not conform to
specifications must be explained and justified on the "Materials Certification", including changes
by virtue of contract change orders. See Attachment #5 for an example, Appendix K of the QAP
Manual.
3 of 4
RECORDS
All material records of samples and tests, material releases and certificates of compliance for the
construction project shall be incorporated into the Project Engineer's project file. If a Federal -aid
project:
• The files shall be organized as described in Section 16.8 "Project Files" of the Local
Assistance Procedures Manual.
• It is recommended that the complete project file be available at a single location for
inspection by Caltrans and Federal Highway Administration (FHWA) personnel.
• The project files shall be available for at least three years following the date of final project
voucher.
• The use of a "Log Summary," as shown in Appendix H of the QAP Manual, facilitates
reviews of material sampling and testing by Caltrans and FHWA, and assists the Project
Engineer in tracking the frequency of testing.
When two or more projects are being furnished identical materials simultaneously from the same
plant, it is not necessary to take separate samples or perform separate tests for each project;
however, copies of the test reports are to be provided for each of the projects to complete the
records.
