2.Include information, engineering analysis, statistical analysis, and test results related to the dispute.
a.Reasons for disputing the acceptance or verification test results.
b.The Contractor’s project quality control test results, including split sample test results. 1) Test results must be from a Department -qualified laboratory using Department -qualified technicians. 2) Include all supporting test data and calculations for reported values.
c.Successful laboratory correlation information when required by material specification.
d.Statistical analysis or identification of potential outliers.
e.Procedures or issues leading to disputed acceptance test results.
f.Incentive/Disincentive calculations based on both Contractor and Department test values, separately .
B.Request to a llow rejected material to remain in p lace
1.Submit the request for approval within one week of receipt of test results or at least 24 hours before performing any work that may prevent the evaluation, correction, or removal of the lot in question.
2.Submit an engineering analysis .
a.Include reasons that the Department should consider allowing the rejected material to remain in place.
b.Include materials, durability, and long- term structural properties from a Department -qualified laboratory as appropriate. Testing may include : 1) Hamburg Wheel Track Testing of Compacted Asphalt Mixtures – Refer to AASHTO T 324. 2) PG Asphalt Binder Tests – Refer to Section 02745. 3) SuperPave Volumetric Properties – Refer to AASHTO R 35. 4) California Bearing Ratio – Refer to AASHTO T 193. 01456 – 4 of 7 5) In-place Concrete Properties for Concrete Pavement and Portland Cement Concrete – Refer to AASHT O T 22, T 24, T 121, T 152. Samples from reinforced structures may be taken only as approved by the Engineer. 6) Air Void System in Hardened Concrete – Refer to ASTM C 457.
c.Include an engineering evaluation based on durability and serviceability relative to the specified product requirements. This includes expected performance compared to design life.
1.6 Dispute Resolution Procedure for Acceptance Or
VERIFICATION TEST RESULTS
A.The Contractor may dispute the validity of the Department’s acceptance or verification tests. 1. The option to dispute the validity of the Department’s test results is forfeited if laboratory correlation testing is required by specification and is not performed.
B.Contractor disputes will not change the Department -selected option for materials acceptance based on sampling and testing as outlined in the UDOT Materials Manu al of Instruction Section 1011.
1.Quality Control results may be used to dispute acceptance test results .
C.The Department immediately reviews the submittal w hen the construction schedule and contractor information indicates that a reject ed lot will be affected within 48 hours by work that may prevent the evaluation, correction, or removal of the lot in question.
1.The Department may suspend work related to the lot in question if merit is found in the engineering analysis.
D.Resolve differences in test results prior to further production of the material type in question.
E.The Department and Contractor immediately begin to investigate and review the engineering analysis and resolve the dispute if merit is found. The investigation includes the following.
1.A test and calculation procedure revie w. Refer to this Section, Article 1.7.
2.Validation t esting as appropriate. Refer to this Section, Article 1.8.
3.Third party testing and r eview as appropriate. Refer to this Section, Article 1.9. 01456 – 5 of 7
F.The Department may choose to evaluate the lot using appropriate test methods if significant errors are identified that cannot be corrected and the quality of the in- place material is in question.
G.The Engineer review s the analysis and notifies the Contractor in writing of their decision. The notification of rejection includes the following:
1.Engineering basis for rejecting the Contractor’s analysis including specific points of objection.
2.Department data and analysis to justify Department position .
3.Time frame for removal of material or pay adjustment to be applied to the lot .
H.The Department will review the Contractor’s schedule and make appropriate adjustments to contract time when significant errors are identified in the Department’s testing results based on critical path analysis . Refer to Section 00555.
1.Time lost due to a rejected analysis is not credited to the contract time.
I.The Department’s response concludes this materials dispute resolution process.
1.Continuing disputes must be addressed and escalated as outlined in Section 00727 and the UDOT and Utah AGC Partnering Field Guide.
1.7 Test and Calculation Procedure Review for Disputed Acceptance Or Verification Test Results
A.The Department and Contractor immediately begin a review of the acceptance test results when the Department concludes the e ngineering analysis has merit and test procedures or calculations are in question. The review normally includes the following in an appropriate order :
1.A review of all equipment , procedures , and methods used for sampling, splitting, and testing.
2.A review of the Department and Contractor’s raw test data and calculations for documentation or calculation errors.
3.Production and testing of additional correlation samples.
4.Cross -witnessing of test procedures by Contractor Quality Control and Department personnel.
5.Distribution of any other pertinent information.
6.Discussion of other possible means for variation.
B.The Department corrects the applicable test results and reapplies the acceptance determination and associated payment if equipment issues or errors in calculations or reporting are discovered. 01456 – 6 of 7
C.The Department evaluates the lot using the original test results if no significant errors are identified.
1.8 Validation Testing for Disputed Acceptance Or Verification
TEST RESULTS
A.Validation testing may be performed by the Department as follows :
1.Department personnel begin retesting on the material remaining from the original Department test.
a.The Contractor’s representative may witness the testing.
b.The Department may perform the validation testing in the Department’s Region or Central Materials laboratory.
c.Retest all samples in the lot.
2.Retesting results are used to validate or invalidate original Department result.
a.Validation test results may not be used instead of acceptance results.
b.Results within two standard deviations of the original acceptance result s are validated. 1) Use the project acceptance results for the lot in question to determine the standard deviation.
3.Invalidated test results are removed from acceptance lot and the lot is reevaluated based on the reduced sample size.
B.The Department evaluates the lot using the original test results if no samples are invalidated.
1.9 Third Party Testing and Review for Disputed Acceptance Or Verification Test Results
A.Third Party testing may be performed as follows :
1.Select an Independent Third Party agreed upon by the Department and the Contractor to witness sample splitting and testing by both the Contractor and the Department if errors in testing cannot be identified .
2.The Independent Third Party identifies and obtains additional material for split -sample testing.
3.The Independent Third Party witnesses split -sample testing in the Department and Contractor Laboratories, evaluates the test procedures, compares the results, determines if there are errors, and provides a report.
4.The party responsible for the identified error pays for the services of the Independent Third Party. 01456 – 7 of 7
B.The Department evaluates the lot using the original testing results if no significant errors are identified.
1.10 Reject Material
A.The Contractor may request that rejected, non- conforming material be left in place at a reduced p rice. Include an engineering analysis .
B.The Engineer determine s whether the lot is to be removed or remain in place and the associated price reduction if other than specified in the contract.
