The District intends to improve approximately 2 acres of landscaping along the East rim of the Thornton Composite Reservoir. The work consists of removing weeds and unhealthy trees and shrubs along Vincennes Road on the East rim of the reservoir and replacing them with more adaptable and resilient plantings, trees and shrubs. Work also includes minor re-grading to enhance the existing soil berms and temporary traffic control measures. Sourcing of plant materials and nursery inspections are anticipated in September with landscape work scheduled to begin in October during the Fall 2022 planting window.
The contractor submitted a cost proposal (CCO-008) for an extra in the amount of $255,647.13. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO08 that the Engineering Department would recommend its approval.
This change order is in compliance with the Illinois Criminal Code since the change is due to circumstances not reasonably foreseeable at the time the contract was signed and is in the best interest of the District.
It is hereby recommended that the Board of Commissioners authorize the Director of Procurement and Materials Management to execute a change order to increase Contract 15-266-4H5 in an amount of $255,647.13 (1.01% of the current contract value), from an amount of $25,314,026.87, to an amount not to exceed $25,569,674.00.
Funds are available in Account 401-50000-645620.
