I I 1 2 Within 30 calendar days after the Contractor's testing, the Engineer may perform 3 verification testing. If the verification testing shows a difference in MRI greater than the I 4 percentages shown in Table 2 of AASHTO R 54 the following resolution process will be 5 followed: 6 7 1. The profiles, equipment and procedures will be evaluated to determine the cause 8 of the difference. 9 I 10 2. If the cause of the discrepancy cannot be resolved the pavement shall be retested 11 with both profilers at a mutually agreed time. The two profilers will test the section 12 within 30 minutes of each other. If the retest shows a difference in MRI equal or 13 greater than the percentages shown in Table 2 of AASHTO R 54 the Engineer's I 14 test results will be used to establish pay adjustments. 15 16 Surface smoothness of travel lanes not subject to MRI testing will be measured with a 10- I 17 foot straightedge no later than 5:00 p.m. of the day following the placing of the concrete. 18 The completed surface of the wearing course shall not vary more than 1/8 inch from the 19 lower edge of a 10-foot straightedge placed on the surface parallel to the centerline. I 20 21 Smoothness perpendicular to the centerline will be measured with a 10-foot straightedge 22 across all lanes with the same cross slope, including shoulders when composed of cement 23 concrete pavement. The overlapping 10-foot straightedge measurement shall be ' 24 discontinued at a point 6 inches from the most extreme outside edge of the finished cement 25 concrete pavement. The completed surface of the wearing course shall not vary more than 26 1/4 inch from the lower edge of a 10-foot straightedge placed on the surface perpendicular to I 27 the centerline.Any deviations in excess of the above tolerances shall be corrected. 28 29 The Contractor shall evaluate profiles for acceptance, incentive payments, disincentive I 30 payments, or corrective action using the current version of ProVAL and provide the results 31 including the profile data in unfiltered electronic Engineering Research Division (ERD) file 32 format to the Engineer within 2 calendar days of completing testing each section of 33 pavement. If the profile data files are created using an export option in the manufacturer's I 34 software where filter settings can be specified, use the filter settings that were used to 35 create data files for certification. Analyze the entire profile. Exclude any areas specifically 36 identified in the Contract. Exclude from the analysis the first 100 feet after the start of the 111 37 paving operations and last 100 feet prior to the end of the paving operation, the first 100 38 feet on either side of bridge Structures and bridge approach slab. Report the MRI results in 39 inches per mile for each 52.8 foot section and horizontal distance measurements in project I 40 stationing to the nearest foot. Include pay adjustments in the results. The Engineer will 41 verify the analysis. 42 43 Corrective work for pavement smoothness may be taken by the Contractor prior to MRI 1 44 testing. After completion of the MRI testing the Contractor shall measure the smoothness of 45 each 52.8-foot section with an MRI greater than 125 inches per mile with a 10-foot 46 straightedge within 14 calendar days or as allowed by the Engineer. The Contractor shall I 47 identify all locations that require corrective work and provide the straight edge 48 measurements at each location that exceeds the allowable limit to the Engineer. If all 49 measurements in a 52.8-foot section comply with smoothness requirements, the Contractor I 50 shall provide the maximum measurement to the Engineer and a statement that corrective 51 work is not required. Unless allowed by the Engineer, corrective work shall be taken by the City of Everett Page AM-26 Amendments 111 Everett Station 80 Stall Parking Expansion June 2019
