QUALITY INDEX FOR PORTLAND CEMENT CONCRETE
CFS:CPM 1 of 9 APPR:JFS:TES:04-30-20
FHWA:APPR:05-19-20
a. Description. This special provision establishes pay factor and price adjustments for Portland cement concrete based on Department administered Quality Assurance (QA) testing of 28-day compressive strength and fresh concrete air content of Portland cement concrete (PCC).
Perform all work in accordance with the standard specifications and this special provision.
Percent-within-limits (PWL) analysis for payment adjustments apply for mainline, shoulder, miscellaneous concrete pavement (including ramps), and concrete pavement overlay applications. Non-PWL analysis for payment adjustments apply for all other applications.
b. Materials. Mixture requirements will be in accordance with section 1004 of the Standard Specifications for Construction, unless otherwise specified in the contract.
c. Sampling. Sampling will be in accordance with subsections 1003.03.H and 1003.03.L of the Standard Specifications for Construction, except as modified herein. A sample is defined as a representative quantity of concrete taken during production which is used to measure the quality characteristics for the concrete. Compressive strength specimens for each sample consist of two cylinders, either 4-inch by 8-inch or 6-inch by 12-inch.
1. PWL Applications. Production lots for PWL analysis are made of at least five approximately equal sublots. The Engineer may approve occasional small individual quantities of concrete to be combined with a larger production lot provided they are of the same grade, contain the same Job Mix Formula (JMF), and are used for the same PWL application.
The random number method for PWL sampling will be used to determine the sampling locations. A random number will be generated for each sublot. The sampling frequency for a production lot is one QA sample per sublot.
If a sublot is not completed in sufficient quantity to permit it to be randomly sampled during its production day, as planned, the quantity of concrete for the sublot that was not placed as part of the day’s production will be sampled during the following production day in accordance with the original random number sampling protocol. The random sample will then represent the total quantity of concrete for the sublot placed over the respective multiple days of production.
If the quantity of a grade of concrete to be sampled on the last day of production for the project is not sufficient to make up three or more equivalent sublots, combine the test results for these one or two remaining sublots, or fraction thereof, with the previous day’s production lot for quality index analysis.
The Engineer will mold and cure two additional compressive strength cylinders, in the same
CFS:CPM 2 of 9 04-30-20 manner as the QA specimens, that are to be retained in the event of dispute resolution.
2. Non-PWL Applications. See subsection 1003.03.L of the Standard Specifications for Construction.
3. Small Incidental Quantities. See subsection 1003.03.J in the Standard Specifications for Construction for reduced sampling and testing for small incidental quantities.
d. Quality Index Analysis. The Engineer’s QA test results will be used to determine the pay factor (PF) and price adjustment (ADJ). The Contractor QC test results will not be used for PF and ADJ analysis. The Engineer will complete PF and ADJ analysis within 7 working days after completion of all 28-day compressive strength testing for the represented production lot or quantity of concrete. All values for PWL, overall lot pay factor (OLPF), and PF are in percent.
PWL values are rounded to the nearest whole number. PF and OLPF values are rounded to two decimal places.
1. PWL Applications. The PWL, PF, OLPF, and associated ADJ will be determined using the MDOT Concrete PWL Worksheet. The acceptable quality level (AQL), rejectable quality limit (RQL), lower specification limit (LSL), and upper specification limit (USP) are shown in Table 1. The Engineer will perform the quality index analysis for all concrete represented by lot size and makeup necessary for random sampling.
Table 1: Quality Index Parameter Specification Limits for PWL Applications
Quality Index Parameters Grade of Concrete
3500/3500HP
28-Day Compressive Strength
Specification Limit – Lower (LSL) (psi) 3500
Specification Limit – Upper (USL) N/A
Acceptable Quality Level (AQL) 95 PWL
Rejectable Quality Level (RQL) 50 PWL
Rejection Limit for an Individual Strength Sample Test Result (psi) 2500
Air Content of Fresh Concrete
Specification Limit – Lower (LSL) (percent) 5.5
Specification Limit – Upper (USL) (percent) 8.5
Acceptable Quality Level (AQL) 90 PWL
Rejectable Quality Level (RQL) 50 PWL
Suspension Limits (percent) < 5.0 or > 9.0
A. Pay Factor Determination for PWL Applications. The MDOT Concrete PWL
Worksheet uses the following formulas to calculate the PF and associated ADJ for each production lot. The maximum calculated numerical values for PF and OLPF will not exceed 105.00.
(1) Pay Factor for 28-day Compressive Strength (PFs). If PWL for 28-day compressive strength (PWLs) is 95 to 100 inclusive, use the following formula to determine PFs:
PFs = 5 + PWLs
CFS:CPM 3 of 9 04-30-20
If PWLs is from 50 to less than 95, use the following formula to determine PFs:
PFs = 47.22 + (0.5556 x PWLs)
If PWLs is less than 50, the production lot is rejectable and the Engineer will require additional evaluation to decide what further action may be warranted as described in section e of this special provision.
(2) Pay Factor for Air Content of Fresh Concrete (PFac). If PWL for air content of fresh concrete (PWLac) is 70 to 100 inclusive, use the following formula to determine PFac:
PFac = 55 + (0.5 x PWLac)
If PWLac is from 50 to less than 70, use the following formula to determine PFac:
PFac = 37.5 + (0.75 x PWLac)
If PWLac is less than 50, the Engineer will elect to do one of the following:
(a) Require removal and replacement of the entire production lot with new testing conducted on the replacement concrete and repeat the evaluation procedure.
(b) Provided no individual test results for the production lot are outside the suspension limits for air content, allow the production lot to remain in place and apply an Overall Lot Pay Factor (OLPF) of 50.00.
(c) Allow submittal of a corrective action plan for the Engineer’s approval. If the Engineer does not approve the plan for corrective action, subsections d.1.A.(2).(a) or d.1.A.(2).(b) of this special provision will be applied, as determined by the Engineer. All costs associated with plan submittal and corrective action under this subsection will be borne by the Contractor. Positive ADJ (quality initiative) will not apply for production lots subject to corrective action.
(3) Overall Lot Pay Factor (OLPF). Use the following formula to calculate the
OLPF:
OLPF = (0.60 x PFs) + (0.40 x PFac)
B. Price Adjustment for PWL Applications. Both pay factors (PFs and PFac) must be
100.00 or greater for the production lot to be eligible for positive ADJ (quality initiative) consideration. Use the following formula to determine price adjustment for each production lot, using the established Base Price for the pay item included in the contract:
ADJ = (OLPF-100)(Price)/100
2 Non-PWL Applications. Positive ADJ (quality initiative) does not apply for non-PWL applications. Each individual QA strength sample test result will be used to determine the PF and ADJ for the respective quantity of concrete that it represents, based on the sampling rate.
CFS:CPM 4 of 9 04-30-20
The specification limits for non-PWL applications are defined in Tables 2 and 3. Unless otherwise specified in the contract, concrete not conforming to the requirements specified in Tables 2 and 3 is rejectable and subject to further evaluation.

A. Pay Factor Determination for Non-PWL Applications.
(1) Pay Factor for 28-Day Compressive Strength (PFs). If the tested strength does not meet the minimum rejection limit in Table 3, the Engineer will require additional evaluation as described in section e. of this special provision. Use the following formula to determine PFs:
PFs = (QA Test Strength)/LSL
(2) Pay Factor for Air Content of Fresh Concrete (PFac). The pay factor for air content of fresh concrete (PFac) will be in accordance with Table 4.
Table 4: Air Content of Fresh Concrete Pay Factor (PFac) for Non-PWL Applications
Air Content of Fresh Concrete (percent) Pay Factor (PFac)
5.5 – 8.5 1.00
5.0 – 5.4 0.50
Below 5.0 Rejection
8.6 – 9.0 0.75
Above 9.0 Rejection
If the air content of fresh concrete is below 5.0 or above 9.0 percent, the Engineer will elect to do one of the following:
Parameter Grade of Concrete
3000 3500 3500HP 4000 4000HP 4500 4500HP
Lower Specification Limit (psi) 3000 3500 3500 4000 4000 4500 4500

CFS:CPM 5 of 9 04-30-20
(a) Require removal and replacement of the entire quantity of concrete represented by the test with new testing conducted on the replacement concrete and repeat the evaluation procedure.
(b) Allow submittal of a corrective action plan for the Engineer's approval. If the Engineer does not approve the plan for corrective action, subsection d.2.A.(2).(a) will be applied. All costs associated with plan submittal and corrective action under this subsection will be borne by the Contractor.
(3) Overall Lot Pay Factor. Use the following formula to determine the OLPF. The
OLPF cannot exceed 1.00:
OLPF = (0.60 x PFs) + (0.40 x PFac)
B. Price Adjustment for Non-PWL Applications. Use the following formula to calculate the price adjustment:
ADJ = (OLPF - 1) x (Price)
3. Small Incidental Quantities. Positive ADJ (quality initiative) does not apply to small incidental quantities. Price adjustment for 28-day compressive strength deficiencies will be based on test results for the corresponding weekly QA test specimens and the pay factor (PFs) calculated in accordance with the formula defined in subsection d.2.A.(1). Price adjustment is calculated using the following formula, using the pay factor for 28-day compressive strength (PFs) and the established base price for the pay item (Price):
(ADJ) = (PFs – 1) x (Price)
e. Evaluation of Rejectable Concrete. The Engineer will require additional evaluation to decide what further action may be warranted. Results for air content testing of fresh concrete are not eligible for re-evaluation.
If the Engineer determines that non-destructive testing (NDT) is appropriate, this work must be done by the Contractor in the presence of the Engineer within 45 calendar days of concrete placement. All costs associated with this work will be borne by the Contractor. Ensure a complete set of non-destructive tests is conducted (in accordance with the respective standard test method) at a minimum of three randomly selected locations. If NDT is used to estimate the in-situ strength, a calibrated relationship between the project job mix formula (JMF) under evaluation and the NDT apparatus must have been established prior to NDT testing in accordance with its respective standard test method.
1. PWL Applications. If the quality index analysis for 28-day compressive strength shows that the RQL has not been met (50 PWL, minimum) for a production lot or the rejection limit for the individual strength sample test result representing the rejected sublot within a production lot has not been achieved (as specified in Table 1), the associated concrete will be rejected.
A. If the results from evaluation of the rejected concrete indicate that the RQL has been met (50 PWL, minimum) for the rejected production lot, or the rejection limit for the individual strength sample test result representing the rejected sublot within a production lot has been achieved, the represented quantity of concrete under evaluation will remain
CFS:CPM 6 of 9 04-30-20 in place and a pay factor for 28-day compressive strength (PFs) of 50.00 will be applied for overall lot pay factor (OLPF) and price adjustment (ADJ) determinations in accordance with subsection d.1 of this special provision.
B. If the results from evaluation of the rejected concrete confirm that the RQL has not been met (50 PWL, minimum) for the rejected production lot, or the rejection limit for the individual strength sample test result represented by the rejected sublot within a production lot has not been achieved, the Engineer will elect to do one of the following:
(1) Require removal and replacement of the entire rejected production lot, or the individual rejected sublot within a production lot, including new initial tests for quality index analysis conducted in accordance with subsection d.1.A of this special provision.
(2) Allow the Contractor to submit a plan for corrective action, for the Engineer’s approval, to address the disposition of the rejected concrete. If the Engineer does not approve the plan for corrective action, subsection e.1.B.(1) will be applied. All costs associated with plan submittal and corrective action under this subsection will be borne by the Contractor.
2. Non-PWL Applications. If the 28-day compressive strength QA test results show that the rejection limit (as specified in Table 3) has not been achieved, the quantity of concrete under evaluation will be rejected and the Engineer will require additional evaluation to decide what further action may be warranted.
Propose an evaluation plan and submit it to the Engineer for approval before proceeding. The results from NDT will be used only to decide what further action is required. This determination will be made by the Engineer, as follows:
A. For non-structural concrete. If no test result from non-destructive testing falls below the lower specification limit (LSL) 28-day compressive strength, the represented quantity of concrete under evaluation will remain in place and a pay factor for 28-day compressive strength (PFs) of 1.00 will be applied for overall lot pay factor (OLPF) and price adjustment (ADJ) determinations will be in accordance with subsection d.2 of this special provision.
B. For structural concrete (including overhead sign foundations). If no test result from non-destructive testing falls below the lower specification limit (LSL), the represented quantity of concrete under evaluation will remain in place and a pay factor for 28-day compressive strength (PFs) of 0.85 will be applied for overall lot pay factor (OLPF) and price adjustment (ADJ) determinations will be in accordance with subsection d.2 of this special provision.
C. If one or more of the non-destructive test results fall below the lower specification limit (LSL) 28-day compressive strength, the Engineer may elect to do one of the following:
(1) Require removal and replacement of the entire rejected quantity of concrete, including new initial tests for quality index analysis conducted in accordance with subsection d.2 of this special provision.
(2) Allow the Contractor to submit a plan for corrective action, for the Engineer’s approval, to address the disposition of the rejected concrete. If the Engineer does not
CFS:CPM 7 of 9 04-30-20 approve the plan for corrective action, subsection e.2.C.(1) will be applied. All costs associated with plan submittal and corrective action under this subsection will be borne by the Contractor.
(3) Allow the in-situ quantity of concrete under evaluation to remain in place and a pay factor (PFs) of 0.50 will be applied for overall lot pay factor (OLPF) and price adjustment (ADJ) determinations in accordance with subsection d.2 of this special provision.

2. Schedule. If the Engineer determines, based on the above criteria, that lot dispute resolution is warranted, the following schedule and testing process will be initiated.
A. The Engineer will document receipt of the request for dispute resolution and will deliver the dispute resolution samples along with the appropriate sample identification submittal forms to the MDOT Construction Field Services (CFS) Central Laboratory for testing within 3 working day of the receipt of the request.
B. The Department’s CFS Central laboratory will test all dispute resolution test specimens within 2 working days of their receipt.
C. The MDOT CFS Central laboratory will return the dispute resolution test results to the Engineer within 10 working days from receipt of the dispute resolution samples.
3. Testing Process.
A. All lot dispute resolution samples will be tested for the production lot under dispute resolution.
B. All dispute resolution test results will replace their respective original QA test results.
C. The PFs for the production lot under dispute will be recalculated using the
CFS:CPM 9 of 9 04-30-20 compressive strength test results from the dispute resolution test specimens.
D. If the recalculated lot PFs is less than or equal to the original corresponding PFs, the costs for dispute resolution sample testing will be borne by the Contractor.
E. If the recalculated lot PFs is greater than the original corresponding PFs, the costs for dispute resolution sample testing will be borne by the Department.
F. The OLPF will then be recalculated using the PFs from the compressive strength dispute resolution test results and the original corresponding PFac.
g. Measurement and Payment. Any positive price adjustment payment made in connection with this special provision will use the following pay item:
Conc Quality Initiative .............................................................................................. Dollar
Conc Quality Initiative is a budgeted amount established in the contract to cover the potential positive ADJ for the pay items associated with the PWL application only. Conc Quality Initiative does not apply to the pay items associated with non-PWL applications.
If a price adjustment is made for reasons included in this special provision, that adjustment will be made using the base price established for the specific item. If a contract unit price requires adjustment for other reasons not described in this special provision, the adjustments will be made using the original unit price and the adjustments will be cumulative.
Separate payment will not be made for providing, implementing, and maintaining an effective QC program. All costs associated with this work will be included in the applicable unit prices for the concrete items. Failure by the Contractor to maintain the proper curing environment during initial cure will not be basis for claim against the Department.
All costs associated with providing, locating, relocating, maintaining, and securing the adequate number of portable initial curing facilities for both the QC and QA strength test specimens will be included in the applicable unit prices for the concrete items. No additional payment will be permitted. The Contractor is responsible for damage, theft, subsequent replacement, and removal after completion of the work for each curing facility used on the project.

C. Design Field of View. Ensure the hemispherical video detection system can reliably detect vehicle presence in the design field of view. Ensure the design field of view is defined as the sensor view when the image sensor is mounted 30 feet or higher above the roadway, when the camera is adjacent (within 15 feet) to the edge of the nearest vehicle travel lane, and when the length of the detection area is not greater than 5 times the mounting height of the image sensor. Within this design field of view, ensure the VIVDS processor unit is capable of setting up a single detection zone for point detection (equivalent to the operation of a 6 foot by 6 foot inductive loop). Ensure a single camera, placed at the proper mounting height, is able to monitor up to and including 5 traffic lanes simultaneously. Ensure a single omnidirectional camera, placed at the proper mounting height, is able to monitor detection zones in at least intersection approaches.
D. Detection Performance. Ensure detection accuracy of the video detection system is comparable to properly operating inductive loops. Detection accuracy must include the presence of any vehicle in the defined detection zone regardless of the lane, which the vehicle is occupying.
