New Roller Gates and Roller Gate Hoists are included on this contract. However, the manufacturer changed their design for the Roller Gate Hoists subsequent to providing information during the design phase of the project. In lieu of a motor with gear reducer, separate combination starter and controls, the manufacturer switched to a AUMA actuator with integrated controls but still requiring a separate starter, which was approved under Submittal Package 21-2. In addition, there were some unknowns at the time of design regarding control devices and wiring that was required. The contractor submitted RFI-18 seeking direction and a recommendation on how to proceed with the control wiring requirements between the Hoist Motor Actuators and the Hoist Motor Starters. Additionally, revisions were also required to the Headrace Distribution Panel circuit breaker, conduit and power wiring size, and motor starter size, necessitated by the approval of the AUMA actuators. The contractor submitted a cost proposal (COR-10) for an extra in the amount of $16,228.30 and a credit in the amount of $0.00, for a net extra in the amount of $16,228.30. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO10, 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 15-830-3D in an amount of $16,228.30 (0.12% of the current contract value), from an amount of $13,226,600.16, to an amount not to exceed $13,242,828.46.
Funds are available in Account 401-50000-645720.
Requested, Catherine A. O’Connor, Director of Engineering, GMR:MMK
