Summary of Specifications:
The City of Jackson is currently accepting RFQP's for 2016 As Needed Materials Testing.
SCOPE OF SERVICES:
MATERIAL TESTS
All testing proposed in the RFQP will be performed in accordance with the appropriate sections of the MDOT Manual for Michigan Test Methods (MTM’s) and the MDOT Density Control Handbook. This work shall include the following:
I. Concrete Tests
a. Concrete testing in the field as required to complete MDOT form 1174A, Inspector’s Report of Concrete Placed.
b. Preparation of concrete cylinders in the field for compression testing.
c. Performance of compression tests of concrete cylinders.
II. HMA Testing
a. Collection of HMA samples from behind the paver in accordance with MTM 324-07.
b. Lab testing at the consultant’s facilities in accordance with the requirements of the appropriate MTM’s to complete MDOT form 1903C (Daily Report of Contractor’s Quality Assurance Tests).
c. Performance of compaction tests on placed HMA in the field using a Nuclear Density Gauge.
III. Soils
a. Sampling and testing in the field to determine maximum density and optimum moisture content.
b. Testing in the consultant’s lab using the appropriate Proctor test to determine maximum density and optimum moisture content.
c. Performance of compaction tests on placed material using a Nuclear Density Gauge.
d. Sampling and testing as required to complete MDOT form 1901 for mechanical analysis.
e. Sampling and testing of abrasion resistance of crushed concrete by the Los Angeles machine in accordance with MTM 102-01.
IV. Pavement Cores
a. Coring of pavement for determination of pavement thickness and base material type and thickness.
V. Soil Borings
a. Sampling of subsurface soils to a depth between five and 25 feet deep.
b. Analysis of subsurface soils to determine soil types, classifications, depths, number of blow counts, N values, depth of ground water, etc. CONCRETE QUALITY ASSURANCE PLAN PREPARATION
Work included in this RFQP includes the preparation of a concrete Quality Assurance (QA) plan in accordance with the requirements of MDOT’s Frequently Used Special Provision 12SP-604A-05 for Quality Control and Acceptance of Portland Cement Concrete (for Local Agency projects only), for each project let through MDOT’s Local Agencies Program. The firm selected as the successful respondent shall perform concrete QA testing in accordance with the QA plan for applicable projects.
MINIMUM REQUIREMENTS FOR TESTING TECHNICIANS
The firm selected as the successful respondent will be required to meet the Michigan Department of Transportation’s Requirements for Performing Construction Engineering on Local Agency Projects. These requirements will apply to all MDOT Local Agency and City of Jackson projects. The technicians and other personnel performing the work must have the training, certifications, licenses, etc. necessary to meet these requirements.
MINIMUM REQUIREMENTS FOR TEST REPORTS
All testing proposed in the RFQP will be documented in reports that are clearly and legibly written, detailed for future reference, and supplied to the City in a timely fashion. Said reports will be completed in accordance with City of Jackson and/or MDOT requirements.
All reports must contain at a minimum the following information:
1. The City’s project name; 2. Date and location of testing; 3. Date and detailed location of sampling (if applicable); and 4. The Testing Technician’s printed name and signature.
TYPES OF TEST REPORTS
I. Daily Job Tickets
a. Will list the technician’s time of arrival to the project site and time of departure from the project site, lunch break start and stop times and total hours worked. Will not list technician’s time of departure from and arrival to the consultant’s office or any off-site prep time.
b. Must be approved and signed by the City’s project inspector at the end of each work day.
c. Will list types of testing performed during Part A (above).
d. A separate ticket will be generated for each project that the technician works on during the work day.
II. Reports
a. Must be clearly and legibly written.
b. Must indicate the sampling location and date of the tested material.
c. Must indicate whether the material tested conforms to specifications.
d. Soil boring reports must be provided within four weeks of the time of boring and sampling.
e. Compression test results for concrete cylinders must be provided within 24 hours of the time of testing on MDOT form 1160A.
f. Density test results must be provided with one week of the time of testing on MDOT form 0582B.
g. HMA lab testing results must be transmitted to the City via fax or email by 9:00am on the next calendar day following the date of paving on MDOT form 1903C. No additional compensation shall be made for the performance of tests after hours or on weekends.
h. Mechanical analysis test results must be transmitted with 24 hours of the completion of testing on MDOT form 1901.
i. All other lab reports other than those listed above must be provided within three days of the time of sampling and/or the completion of lab testing.
j. No extra hours of Technician’s time or overtime will be allowed for writing reports. This is based on the fact that data for and results from any test performed are recorded on the appropriate forms as the test occurs. Therefore, no off-site or other additional report writing time is needed at the end of each work day.
k. No payment shall be made for review of field reports by staff other than the Testing Technician. No payment shall be made for Testing Technician review at any location other than the project site.
