Explanation
1. BACKGROUND: This ordinance authorizes the Director of Public Utilities to enter into a planned contract modification for professional engineering services during construction with Ch2M Hill Engineers, Inc. (Jacobs) for the Blueprint Hilltop - Palmetto/Westgate, CIP #650870-100801, in an amount up to $605,583.00.
This project is being completed as part of the City’s Blueprint Columbus program. This project will construct various types of green infrastructure (GI) throughout the neighborhood which will provide a higher water quality within the region by treating the surface runoff before it discharges to the waterways. The project will also rehabilitate the existing sanitary sewer laterals and install or redirect new roof downspouts so as to reduce inflow and infiltration (I&I) within the sanitary sewer system which will result in fewer water in basements (WIBs), reduced sanitary sewer flows and decreased sanitary sewer overflows (SSOs). This contract modification will provide the funding necessary to conduct additional public meetings and outreach, complete the designs of the GI and private property work as well as the assembly of the bid documents for each of the phases.
The original agreement provided preliminary design services. This modification will concentrate on completing the project construction plans for the pervious pavement plans, assembling the construction documents, bidding the work, conducting engineering services during construction and completing the private property contracts.
The Blueprint Hilltop - Palmetto/Westgate serves multiple planning areas so this project is coded as “53- Greater Hilltop”.
