The engineer determined that certain revisions are required to repair, replace or protect deteriorated steel structures in the C/D Battery Service Tunnel that were not identified in the original contract scope. Work consists of installing one guardrail post, repairing two additional guardrail posts, and filling fifteen (15) pockets in the new floor topping with concrete to prevent water from collecting and corroding the air main supports. The contractor submitted a cost proposal (CO-36) for an extra in the amount of $110,166.91 and a credit in the amount of $0.00, for a net extra in the amount of $110,166.91. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO36, that the Engineering Department would recommend its approval.
This change order is in compliance with the Illinois Criminal Code since the change is 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 16-127-3DR in an amount of $110,166.91 (0.37% of the current contract value), from an amount of $29,408,742.77, to an amount not to exceed $29,518,909.68.
