Explanation
1. BACKGROUND
This ordinance authorizes the Director of Public Utilities to enter into a contract modification with ms consultants, inc. for continued design services for the Fourth Water Plant Transmission Main project, CIP Number 690502-100001, in an amount up to $14,773,063.35.
This contract is for engineering consulting services for the design of water transmission mains that will be constructed in conjunction with the construction of the City’s future Home Road water plant. The transmission mains will extend from the Home Road water plant located at 5992 Home Road, Delaware, OH 43015, to a strategic connection points in the City’s existing water distribution system, specifically the Cleveland/Henderson pressure district.
The initial project funding for Phase 1 was to start preliminary design services. Modification #1 was to add funding for preliminary engineering services for a new Scioto River/Griggs Reservoir crossing(s) into the Cleveland/Henderson pressure districts and associated transmission main alignment(s) to connect the Home Road Water Plant transmission mains due to the existing waterlines crossing the Scioto River not having the capacity to convey flows from the future Fourth Water Plant. Modification #3 added funding to begin detailed design. This contract modification is needed to fund continued detailed design services.
There are several additional planned contract modifications. The final planned contract modification will be for Phase 3, engineering services during construction.
The majority of the transmission main will be located outside the City of Columbus. The portion within the City of Columbus will be located within the Hayden Run Planning Area (30) and the Far Northwest Planning Area (31).
UPDATED TIMELINE
Phase 2 - Detailed Design Services (Modification No. 2 & 3 (Current)) is expected to have a duration of approximately 36 months. Phase 3 - Engineering Services during Construction (Modification No. 4) is...
