Title
Resolution to Approve Change Order No. 1 with CLI Concrete Leveling Inc. for the 2018 Sidewalk Leveling Project ($24,910.00)
Memorandum
Attached for your review and approval is a change order to the Construction Contract with CLI Concrete Leveling Inc. (“CLI”) for the 2018 Sidewalk Repair Project.
This Contract work includes leveling sidewalk slabs that have “vaulted” or “displaced” joints that result in vertical displacements of between ½- and 1-inch, so that the City may avoid removal and replacement of otherwise good sidewalks. Based on the City’s sidewalk-replacement contractor’s unit prices, leveling, as opposed to replacing, one concrete slab will save the City an average of about $171.00 (based upon a typical 5’ wide sidewalk that is 4” thick).
The original project estimate was for the leveling of 1,250 slabs. In advance of construction in each of the 2018 focus areas, slabs were marked for repair, and it became clear that the amount of slabs marked for lifting would exceed the amount originally estimated during project bidding, including the contingency amount. In order to complete all of the needed work for 2018, the attached Change Order No. 1 is appropriate.
Budget Impact
Funding for the project comes from the Street, Bridge, and Sidewalk Millage, and is included in the FY 2018 Sidewalk Repair project budget. The construction contract was approved by City Council on April 2, 2018 for a total authorized amount of $66,500.00. Change Order No. 1 in the amount of $24,910.00 increases the total authorized amount to $91,410.00. It is anticipated that the additional lifting to be done will be offset to some degree by a reduction in the number of sidewalk slabs replaced, thus not having a substantial impact on the overall project budget.
