1. BACKGROUND
This ordinance authorizes the Director of Public Utilities to enter into a planned contract modification for additional preliminary engineering services with ms consultants, inc. for the Fourth Water Plant Transmission Main project, CIP #690502-100001, in an amount up to $1,487,278.00.
This contract is for additional engineering consulting services for the design of water transmission mains that will be constructed in conjunction with the construction of the City’s future fourth water plant. The transmission mains will extend from the fourth 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 contract, Phase 1, is for preliminary design services. This current modification is to add preliminary engineering services for new Scioto River/Griggs Reservoir crossing(s) into the Cleveland/Henderson pressure districts and associated transmission main alignment(s) to connect the Fourth Water Plant transmission mains. The existing waterlines crossing the Scioto River do not have the capacity to convey flows from the future Fourth Water Plant, based on projected plant capacity.
There are two additional planned contract modifications. One contract modification will be for Phase 2, detailed design services. 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). The Citywide Planning Area (99) will be used for the accounting template due to the project covering multiple areas.
UPDATED TIMELINE: The duration of the initial contract for Phase 1 - Preliminary Design Services is 18 months and is expected to begin in Jan...
