Discussion and Consideration of Change Order #9 – Rathje Construction, Original Town Urbanization Project Phase 3 – Motion to Approve

AGENDA ITEM # K-2 AGENDA INFORMATION TIFFIN CITY COUNCIL COMMUNICATION DATE: November 14, 2025 AGENDA ITEM: Discussion and Consideration of Change Order #9 – Original Town Phase 3 ACTION: Approval Overview This report is submitted for Council consideration of Change Order Request No. 9 for the Tiffin Phase 3 Reconstruction Project, submitted by Rathje Construction. The request proposes the addition of a new bid item for Full Depth 9" PCC Patches, which was not included in the original contract. Background & Justification The original bid item (#43) specified HMA Standard Traffic, ½" mix for full-depth patches. The field conditions required the use of 9" PCC patches instead, as shown on sheet O.01 (HFC- 592), totaling 272.3 SY. The alley at Hwy 6 was excluded due to a utility conflict. The PCC patch work is more labor-intensive and includes hand installation of epoxy-coated rebar dowels and rigid dowel bars, requiring additional time and effort. The proposed change includes: Addition of PCC Patch Item: • 272.3 SY @ $165.00/SY = $44,929.50 Deducts from Existing Items: • Excavation Class 10: -$584.55 • Modified Subbase: -$1,818.60 • PCC 9": -$21,239.40 • Pavement Removal: -$2,450.70 • Total Deducts: -$26,092.89 Recommendation Staff recommends approval of Change Order Request No. 9 in the amount of $18,836.61 to add the Full Depth 9" PCC Patch item to the contract for the Tiffin Phase 3 Reconstruction Project.
