Item 1: The existing 800 AT plugs in the spare breakers in the Process Control Building 480V Switchgear were shown to be replaced with 600 AT plugs and set to a 450 AT. An RFP was issued to set the existing spare breakers to 800 AT instead of 450 AT, making the replacement 600 AT plugs no longer necessary. The replacement 600 AT plugs were turned over to the District, however, the installation of the 600 AT Plugs (SOV Line 16.026) did not occur, and a credit was requested for the labor that was not performed. The contractor submitted a cost proposal (CO-55) to delete the labor necessary to install the 600 AT plugs for an extra in the amount of $0.00 and a credit in the amount of $1,267.67, for a net credit in the amount of $1,267.67. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO55, that the Engineering Department would recommend its approval.
Item 2: During shutdown work at Battery D, the contractor experienced downtime for unforeseen issues associated with draining of the mixed liquor and mixing channels, which delayed demolition of slide gates and installation of blind plates. The contractor submitted a cost proposal (CO-57) for experienced downtime for an extra in the amount of $11,036.79 and a credit in the amount of $0.00, for a net extra in the amount of $11,036.79. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO57, that the Engineering Department would recommend its approval.
Item 3: Revisions to 20-inch return activated sludge (RAS) pump discharge piping in the RAS Pump Station are necessary. The current design did not include an air vacuum release valve on this piping. Installing this valve will prevent air from accumulating in the high point of the line. The contractor submitted a cost proposal (CO-60) to provide labor, materials, and equipment necessary to install an air vacuum release valve at the high point of the 20-inch RAS pump discharge piping for an extra in the amount of $21,249.80 and a credit in the amount of $0.00, for a net extra in the amount of $21,249.80. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO60, that the Engineering Department would recommend its approval.
These 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 these change orders to increase Contract 21-091-3P in an amount of $31,018.92 (0.20% of the current contract value), from an amount of $15,565,795.77, to an amount not to exceed $15,596,814.69.
Funds are available in Account 401-50000-645650.
Requested, Catherine A. O’Connor, Director of Engineering, CS:GAK
