Explanation
1. BACKGROUND: This legislation authorizes the Director of Public Utilities to modify (Mod #1) an existing engineering agreement with Brown and Caldwell for Professional Engineering Services (Design Professional, or “DP” services) for the SWWTP Digestion Process Expansion project, CIP 650353-100003. This contract will provide Preliminary Design Services (Step 1), Detailed Design and Bidding Services (Step 2), and Services During Construction (Step 3) for this project. The initial phase of this contract provided Professional Engineering Services for Preliminary Design (Step 1) and Professional Engineering Services for Detailed Design and Bidding Services (Step 2).
This modification is for a redesign of the original SWWTP Digester Process Expansion and will keep the design for the Digester 6 cover, Digester 7, electrical building, digester boiler system rehabilitation, and rehabilitation of Digester 1-5. The design will be modified to keep the Acid Phase Digesters (APD), modify the surface withdraw piping, replace all steam injectors, and provide a new foam separator and sediment trap for Digester 07.
A future renewal will be requested for Step 3, Engineering Services During Construction, which will include technical project representation (TPR) duties, construction-phase engineering, start-up and commissioning assistance, and record documentation. Construction Management Services will be performed by others.
Planning Area: 99 - City wide
1.1 Amount of additional funds to be expended: $397,198.00
Original Contract $ 2,461,829.00
Modification 1 (current) $ 397,198.00
Total $ 2,859,027.00
1.2 Reasons additional goods/services could not be foreseen:
This is a unplanned modification.
1.3 Reasons other procurement processes are not used:
This work cannot be bid out because the DP had a completed and biddable design at the time that this project was placed on hold. Most of the major modifications to the design are removing those items that were associated with the APDs. A new RFP process would require a new, full redesign and cost much more money.
1.4 How cost of modification was determined:
The cost of the modification was determined through negotiation with the design team including the scope and cost.
2. THE PROJECT TIMELINE: This modification is anticipated to be executed in September of 2019 with a completion date of 180 days after notice to proceed is given
3. EMERGENCY DESIGNATION: An emergency designation is not requested at this time.

5. ENVIRONMENTAL IMPACT: SWWTP Digestion Process Expansion project will increase the beneficial re-use of biosolids in the liquid land application and deep row hybrid popular (DRHP) programs by providing more anaerobically-digested Class B biosolids. The primary goal of this project is to provide sufficient expanded anaerobic digestion facilities and all necessary associated piping and pumping capacity to successfully accommodate the additional solids produced by the Chemically Enhanced Primary Treatment (CEPT) process and the additional solids loadings to the SWWTP resulting from the anticipated growth of the City of Columbus.
6. FISCAL IMPACT: This ordinance authorizes an expenditure of up to $397,198.00 from the Sanitary Sewers G.O. Bond Fund 6109.
