Explanation
1. BACKGROUND: This legislation authorizes the Director of Public Utilities to modify (Mod #1) an existing professional engineering agreement with CHA Consulting, Inc. for the Moler Street Overflow Interceptor Sewer project, CIP 650763-100000. This project will develop, design, and provide engineering services during construction for the City’s Moler Street Overflow Intercepting Sewer and Moler Street Storm Sewer Relocation Project. The overflow interceptor sewer will convey Moler street regulator combined sewer overflows and the south side interceptor sewer wet weather flows directly into the OARS tunnel thru Shaft 3. The storm sewer will be relocated north to provide a discharge location for future inflow redirection in the Moler and Markison tributary areas.
Major scope changes include disconnecting the Moler Street Storm sewer from the Moler Street regulator main storm overflow channel. The Moler Street storm sewer will be redirected north with a new discharge to the Scioto River west of Gates Street. Additional modifications to the Moler Street regulator chamber are required. The disconnection/redirection of Moler Street storm sewer provides future inflow redirection to mitigate Water- In-Basement (WIB) occurrences within the Moler Street combined sewer area and northern portion of the Markison Avenue combined sewer area. Modifications to Moler Street regulator chamber allow capture of its combined sewer overflow and direct conveyance into OARS Shaft 3 using existing storm sewer overflow pipes.
Services will include: field activities to obtain design data, development of a design report, prepare detailed plans and specifications, easements, permits, bid documents, public outreach & coordination activities and provide engineering services during construction. Planning Area: South Side (63)
1.1 Amount of additional funds to be expended: $1,102,239.19
Original Contract $1,751,584.61
Modification #1 $1,102,239.19
Contract Total $1,853,823.80
1.2 Reasons additional goods/services could not be foreseen:
The modified contract includes services to develop, design, and provide engineering services during construction for the City’s Moler Street Overflow Intercepting Sewer and Moler Street Storm Sewer Relocation Project. The Moler street regulator combined sewer overflows and south side interceptor sewer wet weather flow will be conveyed directly into OARS tunnel thru Shaft 3 using the existing storm sewer pipe and a small section of new sewer. The Moler street storm sewer will be relocated north to provide a discharge location for future inflow redirection in the Moler and Markison tributary areas. (Note: for additional information, please see the attached Director’s Information Sheet.)
1.3 Reasons other procurement processes are not used:
The Moler Street Overflow Intercepting Sewer and construction must be completed by December 31, 2022 per the Ohio Environmental Protection Agency consent orders and City of Columbus Integrated Plan and 2015 WWMP Update Report. To complete the Moler Street Overflow Intercepting Sewer on schedule, the contract modification cannot be bid out.
1.4 How cost of modification was determined:
The cost was determined by negotiations between CHA Consulting, Inc. and DOSD. (Note: for additional information, please see the attached Director’s Information Sheet.)
2. Project timeline: This modification is expected to be completed by December of 2022.
3. EMERGENCY DESIGNATION: Is not requested at this time.
4. CONTRACT COMPIANCE NO: 16-0966259 | 06/06/2019 | MAJ | Vendor: 000802
5. ECONOMIC IMPACT: This project was identified in the City of Columbus Integrated Plan and 2015 WWMP Update Report which was developed with input from various stakeholders and submitted to Ohio EPA. This project will mitigate combined sewer overflows into the Scioto River from the Moler street combined sewer regulator and provide wet weather relief of the South Side interceptor Sewer. This project will design and construct a municipal separate storm sewer outfall to the Scioto River. Short term economic impacts will be in terms of the prime and six sub consultants design work on the project.
6. FISCAL IMPACT: This legislation authorizes the transfer within and the expenditure of up to $ 1,102,239.19 from the Sanitary Sewer General Obligation Bond Fund, Fund 6109; and amends the 2018 Capital Improvements Budget.
