Explanation
1. BACKGROUND: The Jackson Pike Wastewater Treatment Plant operates two (2) screening channels as part of the headworks unit treatment process. The current screenings press was installed in 2008 as part of J210. Due to the larger amount of screenings, leaves and debris in the raw sewage the screening press is unable to keep up with output from the mechanical screens. Additionally the Screen Room was constructed in the 1930’s and requires a holistic evaluation to ensure the equipment and building systems are providing the appropriate service for treatment and plant staff. Planning, design, and construction of the screening improvements will be conducted to avoid continued adverse impact to treatment.
Step 1 of this project, Preliminary Design, will include the following tasks: 1. Review existing facility information, 2. Provide an assessment of the screening system and building, 3. Develop design criteria and basis of design for the project, 4. Provide an evaluation and analysis for the screen system and building.
The City received the Final DDM on September 17, 2020. Step 2, Detailed Design includes preparing construction contract documents (including specifications and drawings) in accordance with City of Columbus Division of Sewerage and Drainage standards, guidelines, and directions for construction and implementation of the proposed facility. Detailed Design will also include attendance at plan and specification review meetings, assisting in negotiations, permitting, and other matters with U.S. EPA, Ohio EPA, and other government agencies as necessary, and bidding services (which includes assisting at the Pre-Bid Conference, and bid opening, making an award recommendation for lowest and best bide, and preparing Conformed to Contract Documents).
A future, second renewal will be requested for Step 3, Engineering Services During Construction, which will include technical project representation (TPR) duties, construction phase engineering, start...
