Explanation

BACKGROUND: This legislation authorizes the Director of Public Utilities to modify an existing engineering agreement with Black & Veatch Corporation for the Lockbourne Intermodal Subtrunk Air Quality Improvements project, CIP 650491-100005. As part of the Northern Pickaway Joint Economic Development District (JEDD) agreement the City of Columbus agreed to construct the sanitary sewer infrastructure necessary to serve the district. A majority of that area will be served via the 60-78” Lockbourne Intermodal Subtrunk Sewer (LIS) which is currently under design. During the design of this sub-trunk, a preliminary ventilation and odor control study conducted by HWS (Harvey W.

To date, the consultant has completed the project design, bidding phase and has conducted 12 months of engineering services during construction.

This project is located in the 64 - Far South Columbus Community.

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 un...
