Meeting Fiscal Impact (Y/N) Dollar Amount Budget Source Category Type Information September 17, 2024 - REGULAR MEETING OF THE MOUNT PROSPECT VILLAGE BOARD Y $17,172.54 South Mount Prospect Tax Increment Financing District Fund CONSENT AGENDA Action Item The Village Board awarded a construction contract to Schroeder Asphalt Services in the amount of $209,172.00 at their April 16, 2024, meeting for site improvements at Fire Station 11. The scope of work included resurfacing the paved areas (access roadway and parking lot), adding curb & gutter and storm inlets along the access roadway to improve drainage, replacing storm sewer pipe in the parking lot, and grass restoration. Bid items included calculated amounts of asphalt removal and replacement based on the paved area and estimated thickness of the asphalt. The project also estimated a percentage of the stone sub -base to be replaced with concrete once the asphalt was removed and sub -base evaluated by staff. During construction, it was evident that a greater than anticipated amount of sub -base needed replacement to provide a proper sub -base that would not lead to premature deterioration of the asphalt pavement. Staff determined additional asphalt pavement was necessary (both area and thickness) to properly drain the parking lot and access driveway, assuring no adverse impacts to adjacent properties. Measured quantities for asphalt removal and replacement, concrete patching, and associated items exceeded the original bid quantities. The final construction amount is $226,344.54, $17,172.54 above the contract amount of $209,172.00. An 8.2% increase above the contract amount. The contract amount of $209,172 did not include a 10% contingency. All work associated with this contract has been completed and found to be acceptable. The additional work directed by staff will ensure that the parking lot and access driveway will last for the expected life of 20 years with standard future maintenance. The overall cost for the rehabilitation of Fire Station 11 remains well under the $1,733,500 project budget. Discussion Not applicable. Alternatives 1.

ENGINEER: VILLAGE ENGINEER The following changes are hereby made to the Contract documents: Description: As work progress field changes were made to adjust the project to match existing field conditions. The class c patch was widened in several areas to repair a soft pavement base. The manhole in the center of the concrete pavement could not be adjusted. The manhole had to be reconstructed by removal of the cone section and installing a barrel section with adjusting rings. The quantities for the binder and surface increase due to the following factors: The area of the access road at Algonquin was widened to better match the adject driveways. The parking area on the north and east side required additional material to promote drainage from the buildings to the inlet, proved a uniform slope across the parking area and to provide more cover over the new storm sewer.
