Explanation
BACKGROUND: This legislation authorizes the Director of Public Utilities to enter into an engineering agreement with Aldea Services, LLC for the Central College Subtrunk - Phase 3 project, CIP 650033-100003, in the amount of $2,522,381.00. This project will extend the reach of the Central College Subtrunk to its full build out capacity and will allow the City of Columbus to extend its service area along Central College Road as well as Harlem Road thus creating additional utility and tax base. It will also allow for future developments and extensions of sanitary sewers into new or existing neighborhoods that would have previously had to utilize a home sewage treatment system. This will increase runoff and ground water quality for the region.
The City of Columbus Division of Sewerage and Drainage (DOSD) initiated CIP 650033-100003 to provide the detailed design, specifications, contract documents, Geotechnical Baseline Report (GBR) (if authorized) and other reports required for the construction of the Central College Subtrunk Phase 3 extension. The project will start from the planned end of Phase 2 of the 30” sanitary subtrunk near 5372 Central College Rd and continue easterly along Central College Rd to its final upstream termination point at its intersection with New Albany Rd W. It is intended to fully intercept the flow from the 27” Sugar Run Subtrunk at this point. The project will also extend a sanitary subtrunk along Harlem Road from Central College Road, north, to Walnut Road in order to provide service to the northern portion of the tributary area as indicated on Schedule 6. Due to the sewer depth, adjacent utilities, narrow right-of-way and stream crossings, it is anticipated that trenchless construction methods will be needed for most if not all portions of these alignments.
PROJECT TIMELINE: It is anticipated that the contract documents will be signed/executed in early 2017. Detailed design is expected to take 1.5-2 years to complete. ...
