There are two change orders, CO-19 and CO-20. The work for COR-19 includes removing, modifying, and relocating ferric chloride dosing piping to the influent channels of the final settling tanks for Battery A at the Stickney WRP. The work also includes removing and reinstalling heat tracing and providing additional supports for the ferric chloride piping. This revision is necessary to avoid interference with ramps and stairs being modified under a future contract. The value of CO-19 is an extra in the amount of $19,415.61 and a credit in the amount of $0.00, for a net extra in the amount of $19,415.61.
The work for CO-20 includes installing a leak detection system for the ferric chloride dosing piping in the lower Operating Galleries of Batteries A, B, C, and D and Service Tunnels A-B and C-D at the Stickney WRP. This revision is necessary to detect any leaks in the dosing system and thereby save chemical wastage. The value of CO-20 is an extra in the amount of $57,774.97 and a credit in the amount of $0.00, for a net extra in the amount of $57,774.97.
The combined total of CO-19 and COR-20 is an extra in the amount of $77,190.58 and a credit in the amount of $0.00, for a net extra in the amount of $77,190.58. The work has not been completed. The engineer reviewed the proposals, found them to be reasonable, and stated via correspondences CO19 and CO20, that the Engineering Department would recommend its approval to the Board of Commissioners.
The above 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 19-159-3P in an amount of $77,190.58 (0.88% of the current contract value), from an amount of $8,776,938.40, to an amount not to exceed $8,854,128.98.
