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 Black & Veatch Corporation for the Lower Olentangy Tunnel - Phase 1 project, CIP #650724-100000, in an amount up to $5,072,270.32.
Professional construction management services are needed to ensure construction of the Lower Olentangy Tunnel follows the requirements and specifications of the project design and that the City receives an end product capable of providing the intended function. Existing City staff is not adequate to devote multiple qualified personnel full time to management of the project construction activities. These activities include full time construction inspection, project coordination, reporting, budgeting, scheduling, document tracking, and startup coordination. Much of the project alignment generally follows Olentangy River Road. This is a planned contract modification to add funds to continue the work.
The project is in the Citywide Community Planning Area #99.
