Explanation
1. BACKGROUND
This ordinance authorizes the Director of Public Utilities to enter into a contract modification for engineering services during construction with Arcadis US, Inc. for the JPWWTP Cogeneration Facility project, CIP #650250-100007, in an amount up to $962,500.00.
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 recent feasibility study shows 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 installing office space.
Preliminary design and detailed design were completed. Modification 3 was intended to progress the work through the end of construction. However, due to construction delays of more than a year and a half, a new modification is required. This current modification will complete remaining engineering work and progress through the duration of construction. A separate construction project is underway and is expected to be completed by second quarter of 2025, and all engineering work will also be complete at that time.
