Explanation
1. BACKGROUND: This legislation authorizes the Director of Public Utilities to modify (#3) an existing professional engineering agreement with Arcadis US, Inc. for the Jackson Pike Waste Water Treatment Plant (JPWWTP) Cogeneration Project, CIP 650250-100007. The Jackson Pike Wastewater Treatment Plant creates large amounts of methane-rich digester biogas which is now burned in flares as a waste product. A feasibility study showed that installing a cogeneration system can beneficially use this biogas as fuel to create electricity that will supply about half the total electricity the plant uses, with an acceptable payback period and significant overall reductions in greenhouse gas emissions. The cogeneration system will be relatively large and complex. This project also includes design work for replacing certain plant boilers at the end of their useful life and improvements to the CMT facilities. This renewal purchases the remaining step 3 services during construction. Construction is being accomplished by others under a separate contract.
The construction work will occur at the Jackson Pike Wastewater Treatment Plant and has been designated as planning area 99, Citywide.
1.1 Amount of additional funds to be expended: $1,907,793.00
Original Contract $1,025,883.00
Modification No. 1 $2,309,950.00
Modification No. 2 $1,299,989.00
Modification No. 3 (current) $1,907,793.00
CURRENT PROPOSED TOTAL $6,543,615.00
1.2 Reasons additional goods/services could not be foreseen:
This is a planned modification/renewal.
1.3 Reason other procurement processes are not used:
Re-bid of the project will likely result in a higher project costs as much of the project history would be lost and would need to be rediscovered by another consultant unless the new RFP were won by the same consultant. In such a case, we would have missed significant time in acquiring and evaluating the new proposals without significant benefit.
