MORAGA QUALITY ASSURANCE PROGRAM

QUALITY ASSURANCE PROGRAM

JANUARY 2016

Town of Moraga Quality Assurance Program

1

INTRODUCTION The Town of Moraga (Town) has adopted this Quality Assurance Program (QAP) to ensure that the materials and workmanship incorporated into our construction projects are in conformance with contract specifications. This program is periodically reviewed and updated a minimum of every five years.

The QAP has been approved by the Public Works Director/Town Engineer, Edric Kwan, and a registered Civil Engineer in the State of California. A copy of the QAP shall be kept on file and available for Caltrans review.

SCOPE This QAP is applicable to federally-funded projects off the National Highway System (non-NHS projects). This adopted QAP is mandatory for federal-aid projects, and must comply with the pertinent sections of Chapter 16.14, “Quality Assurance Program,” of the Caltrans’ Local Assistance Procedures Manual (LAPM) and prepared in conjunction with the Caltrans’ Quality Assurance Program Manual for Use by Local Agencies – revised January 20, 2011. For federally funded projects on the NHS, the Town of Moraga will follow the Caltrans QAP and Chapter 16.14, “Quality Assurance Program,” of the Caltrans’ LAPM.

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.

MATERIALS LABORATORY The Town of Moraga 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.


2

The Contractor shall not select or exercise any authority over the laboratory selected to perform the AT. In addition, the Contractor will be restricted from using the same private consultant laboratory for its own quality control testing.

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 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.

The Resident Engineer shall keep copies of the certifications for the laboratory and the individual personnel performing the AT on the project. The laboratory is responsible for performing the calibrations and providing the Engineer with calibration records.

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 Caltrans (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


3

at the locations and frequencies as shown in Attachment #1 (Appendix D, “Acceptance Sampling and Testing Frequencies” of the Caltrans QAP Manual). AT frequencies may be modified in writing by the Engineer at his/her discretion.

The Engineer shall maintain a material and testing “Summary Log” for each material requiring multiple sampling and testing as defined in the contract specifications or frequency tables in Attachment #1. The “Summary Log” shall include appropriate data such as station location, depth of test sample, approximate quantity of material represented by the test sample, test result, and tester. Failing tests results require retesting of the material with cross references of the retest to the initial failing test result previously entered in the “Summary Log.”

Whenever failures occur, sufficient additional acceptance tests should be taken to isolate the affected work. Documentation of the results of such additional tests shall be included in the records, including a description of the corrective measures taken.

The frequency of sampling and testing is intended as a guide under normal conditions. Material well within specifications and uniform in character may result in less frequent sampling and testing, whereas borderline materials may need an increase in the frequency of testing to assure specification compliance. Materials supplied from reliable sources and proven by frequent testing to be of uniform high quality, may subsequently receive less sampling and testing than indicated in the contract specifications; however, deviations from the prescribed frequency must be noted and explained in the material testing records. When materials are being furnished intermittently, with interruptions of several days or weeks, the frequency of sampling and testing should be increased to assure that specification materials are being incorporated into the work.

Minor Quantities Relatively minor quantities of construction materials may be accepted without testing provided acceptance conforms to the conditions stated below. Generally, this provides for accepting minor quantities of materials from a commercial source that is known to be a supplier of specification material.

1. The Engineer, on the basis of a visual examination, may accept minor quantities of materials without testing provided the source of the supplies has recently furnished similar materials found to be satisfactory using normal sampling and testing requirements.

2. Acceptance of a product may be established on the basis of certification by the manufacturer or supplier that the material furnished complies with all specification requirements.

Documentation for acceptance of material as described above must be provided and included in the project records. Documentation should include statements in the project inspector’s reports that clearly indicate conditions under which the material was accepted (e.g., description, quantity, location, where placed, certification numbers and/or other accompanying data).


4

The following list suggests approximate maximum quantities of materials that may be accepted under the conditions indicated above:

Aggregates other than for use in Portland Cement Concrete--not to exceed 100 tons per day or more than 500 tons per project

Bituminous mixtures/Hot Mix Asphalt--not to exceed 50 tons per day. Sample at Engineer’s discretion if project total is less than 500 tons

Bituminous material--not to exceed 100 gallons per project

Paint--not to exceed 20 gallons per project. Acceptance to be based on weights and analysis on container

Masonry items--check dimensions of products for specification compliance and uniformity of manufacture

Non-reinforced or clay pipe--not more than 100 lineal feet

INDEPENDENT ASSURANCE PROGRAM (IAP) IAP shall be provided by personnel from Caltrans or the 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. For On-NHS projects, LAPM Chapter 16.14 procedures apply. For Off-NHS projects, the Engineer shall verify that its consultant laboratory’s QAP includes IAP procedures for “testing its own testers,” and calibrating its own laboratory equipment.

IAP personnel shall be certified in 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.

During witness and split sample testing, acceptance testers should carry adequate identification with them so that Independent Assurance sampling and testing personnel can verify certification of personnel. Acceptance testers without valid identification shall not be allowed to perform sampling and testing.

Split sampling shall be at the Engineer’s discretion if test results are deemed questionable. Material samples will be split and will compare the test results between the Acceptance Tester and the Independent Assurance Sampler and Tester from a second independent lab.


5

REPORTING ACCEPTANCE TESTING RESULTS The following are time periods for reporting material test results to the Resident Engineer:

When the aggregate is sampled at material plants, test results for Sieve Analysis, Sand Equivalent and Cleanness Value should be submitted to the Resident 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 Resident 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 Resident Engineer within 72 hours after sampling.

(2) Test results for “R” Value and asphalt concrete extraction should be submitted to the Resident 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 Resident Engineer’s staff, shall be done on an expedited basis such as by fax or telephone.

TESTING OF MANUFACTURED MATERIALS The Engineer will select the procedures for inspecting, accepting, and testing manufactured or prefabricated materials by either source inspection, job site inspection, and/or certificate of compliance.

The Town of Moraga generally does not have personnel available to conduct source inspections at plants and facilities. During the Design phase of the project, the Project Engineer may submit a “Source Inspection Request” see Attachment #2 (Exhibit 16-V of the LAPM) to the quality assurance consultant or Caltrans for inspection and testing of manufactured and prefabricated materials by their materials laboratory. The procedures for requesting source inspection from Caltrans is outlined in the Chapter 16 of the LAPM.

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.

The Town of Moraga may accept manufactured products, materials or assemblies if accompanied by a Certificate of Compliance, provided they do not involve structural integrity or public safety. Such Certificates shall be signed by the manufacturer and shall state that materials and workmanship conform in all respects to the project


6

specifications for the material. 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).

In addition to the required Certificate of Compliance, job site inspections will be conducted by the Engineer and/or quality assurance consultant to visually inspect manufactured materials for flaws and defects. The certified material’s lot number and project number shall be identified on the certificate and on lot tags or stenciled on the material. In addition, this data shall be referenced on the inspector’s daily logs and laboratory reports. Certified materials may be sampled and tested again on the job site, and rejected for cause whether in place or not.

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 Resident 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 Resident 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).

RECORDS All materials records of samples and tests, material releases and certificates of compliance for the construction project shall be incorporated into the Resident 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 Attachment #6 (Appendix H of the QAP Manual), facilitates reviews of material sampling and testing by Caltrans and FHWA, and assists the Resident Engineer in tracking the frequency of testing.

Canyon Road Looking Southbound at Camino Pablo Intersection

Construction Notification The Town will provide door hanger construction notification to residents within 300 feet of the project. The notification will provide project information about times of construction, type of work to be performed, contact phone numbers for additional information or issues. Additionally the Town will place electronic message signs and/or stationary signs informational signs to provide advance notice of potential traffic delay periods and include contact numbers for additional information or for reporting of concerns and issues. The Town will contact local schools to inform about and coordinate construction work in effort to lessen impacts during school pick up and drop offs. Additionally the Town while school is session will limit lane closures before 9 AM and after 3:30 PM. Traffic Control During Construction Temporary traffic control systems in accordance with Manual of Uniform Traffic Control Devices and the Town of Moraga standards will be implemented. Town will place electronic message signs and/or stationary signs informational signs to provide advance notice of construction activities. Where there is one lane in each direction, flaggers and advanced warning signage will be provided during construction. Flaggers will direct the



flow of traffic along the single lane, alternating between northbound and southbound traffic. Where there are multiple lanes in each direction, a single lane in each direction will be accessible within the work area. Both lanes will be open at the end of every day. Pedestrian and cyclist access will be provided through the work zone at all times during construction. The contractor will be required to prepare a site-specific traffic control plan for review and approval by the town’s engineer prior to commencing work and follow the Town’s Work Zone Implementation plans. The construction timeline is approximately six weeks per site for this project. The authorized working hours for the project is 7:30 am to 5:00 pm. Moraga Way Temporary Impacts to Parking and Property Access The street is a minor arterial leading in and out of Town. The project site has bike lanes in each direction and very limited exclusive car parking area. No residential properties affront the project streets. At least one driveway will remain open for all properties with multiple driveways. Properties with a single driveways may only be closed with a 48 hour advance notification to residents for construction activities at that property location with closure not lasting more than 7 days. Alternative parking will be provided with reasonable distance from the effected property. Along Moraga Way, there is limited on-street parking that is not used by businesses and residences. Businesses and residences along Moraga Way have on-site parking and available parking on side streets. The on-street parking that is by Ivy Drive is primarily used during school drop-off hours for Miramonte High School. The Town will coordinate all work with the school directly to address parking and provide-signage to alternate parking areas.

Moraga Way Looking South from Ivy Drive (on-street parking) The Town of Moraga has a fire department located along Moraga Way just North of the School Street intersection. Access to the Fire Station will be available at all times for the Fire Department.



Moraga Fire Department Moraga Way Temporary Impacts to Bus Stops Along Moraga way, there a several bus stops owned by the County Connection within the project limits. The Town will work with the County Connection to maintain bus stops during construction.

Overview: Moraga Way between Moraga Valley Lane and School Street



Overview: Moraga Way between School Street and Moraga Road Canyon Road Temporary Impacts to Parking and Property Access The street is a minor arterial leading in and out of Town. The project site has bike lanes in each direction and is not striped for exclusive car parking. Canyon Road is not signed for any public parking, thus no public parking will be reduced by construction activities. There are no businesses or residences (including no driveways) affronting Canyon Road and no property access would be affected by construction activities. St. Monica’s Catholic Church Secondary Driveway There is only one property, St. Monica’s Catholic Church, 1001 Camino Pablo Drive, that has a driveway (secondary driveway) along Canyon Road. The church’s two (2) primary driveways are located along Larch Drive and Camino Pablo Drive. Town will coordinate construction activities with church, but with that said the Town will maintain access to the church throughout the project. Canyon Road Consistency with Town Bike Plan The Canyon Road portion of the project is consistent with the Town’s Moraga Walk and Bike Plan. Bike lanes are being striped along Canyon Road as planned in the Walk and Bike Plan. Canyon Road is intended to have bike lanes and transitions to a bike route just south past Camino Pablo.



St. Monica Catholic Church, 1001 Camino Pablo Road (has 2 alternative driveways driveway along Camino Pablo and Larch Avenue)
