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). During the design of this sub-trunk, a preliminary ventilation and odor control study conducted by HWS (Harvey W. Sorensen) in September of 2013 determined that air quality control would be required in order to prevent odor releases and pressurizing of the sanitary system. To date, the consultant has completed the project design, bidding phase and has conducted 30 months of engineering services during construction.
This project is located in the 64 - Far South Columbus Community.
