Explanation
1. BACKGROUND
This Ordinance authorizes the Director of Public Utilities to modify and increase the professional engineering services contract with MS Consultants, Inc., for the Southerly Stormwater and Floodplain Improvements project, CIP #650377-100000, in an amount up to $3,974,725.81, to pay for the first phase of detailed design services.
The City’s Wastewater Treatment Plants require continual development and upgrades in order to keep processes and equipment up to date, in compliance, and running well. All re-development requires compliance with the City of Columbus Stormwater and Drainage Manual as well as Ohio Environmental Protection Agency (OEPA) Stormwater general permit and Federal Emergency Management Agency (FEMA) requirements. This project will provide a phased development stormwater and floodplain masterplan for the Southerly Wastewater Treatment Plant.
The first phase of the contract performed preliminary engineering and analyzed several alternatives for meeting these regulations while accounting for any unmitigated historical impacts and anticipated future development. Findings of the initial phase are that a levee is required to accommodate future expansion necessary to accommodate the expected increase in flows from Intel and other large developments in our service area.
Due to the size and complexity of the project the detailed design will be split into two phases, which are being called Step 2a and Step 2b. Step 2a is the current phase of work and is performing field investigations and developing technical memoranda (TM) required to fully define the environmental permitting, developing proposed environmental mitigation plans, and will progress the design through 30% design package.
Due to uncertainty about which footprint would be selected, there were several if authorized tasks that were included in phase 2A. Due to fiscal constraints, the negotiated fee for step 2A was not fully legislated. Since the initial par...
