While performing contract work, the contractor encountered field conditions that required changes to the original contract and are listed below.
Item 1: An extra in the amount of $26,605.16 is necessary for the installation of a 60-inch manhole structure at the intersection of 135th Street and Claire Boulevard. During installation of a proposed manhole structure (MH-2) in this location, the contractor discovered an existing 12-inch storm sewer was not able to be connected to MH-2 due to its location deviating by approximately 15 degrees from the location provided by the village of Robbins. After the District was notified of this issue, a request for proposal (RFP-11) was issued to the contractor to install an additional manhole structure in this location to connect the 12-inch storm sewer lateral to another 36-inch storm sewer and for any restoration work related to the additional manhole structure. The contractor proceeded with the installation of the additional manhole structure at their own risk since the road had already been excavated for the installation of MH-2. The contract has submitted a cost proposal (CO24) for an extra in the amount of $26,605.16. The engineer reviewed the proposal, found it to be reasonable, and recommends its approvals.
Item 2: An extra in the amount of $2,413.68 is necessary to due to erosion concerns at the outfall of three 6-inch drainage pipes installed under the new pedestrian path along Woodlawn Avenue. After installation of the drain pipes, the contractor and the District observed minor erosion, and a cost proposal (CO25) was submitted to place rip rap at the base of the drain pipe outfalls to extend to the new diversion channel. The contractor submitted a proposal for an extra in the amount of $2,413.68. The engineer reviewed the proposal, found it to be reasonable and recommends its approval.
The above two change orders are in compliance with the Illinois Criminal Code since the changes are germane to the contract.
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 14-253-AF in an amount of $29,018.84 (0.26% of the current contract value), from an amount of $10,991,596.84, to an amount not to exceed $11,020,615.68.
Funds are available in Account 501-50000-645620.
