Gable, P.E., Deputy Director of Engineering – Design & Construction Mason Hughes, Civil Engineer I Re: Resolution 25-23 – Accepting the Lowest and Best Bid for the Tartan West Water Tank Repainting Project, 22-017-CIP Summary On February 23, 2023, five (5) bids were received and publicly opened for the Tartan West Water Tank Repainting Project (Project) which consists of repainting the exterior of the 500,000 gallon spheroid water tank located at 7160 Glacier Ridge Boulevard and perform small additional repairs. Please see the attached exhibit for the specific project location. This necessary maintenance ensures the longevity of the water tank by preventing corrosion. This Project utilizes technical specifications in place of construction drawings. The technical specifications can be provided to Council upon request. The scope of work for this Project was determined from recommendations provided in a 2020 inspection report conducted by Dixon Engineering. Dixon Engineering is also contracted to perform inspections of the tank painting. The budgeted funds for the Program in the 2022-2026 Capital Improvements Program (CIP) are $390,000.00 for the Tartan West Water Tank Repainting (EW172). Funding for the Project is being re-appropriated in 2023 through the adoption of Ordinance 10-23 on March 27, 2023. The Engineer’s Estimate for the Project is $207,900.00. Midwest Tank Management submitted the lowest and best bid of $143,300.00. Staff has reviewed all bids and a summary of the bids received is listed below. Two bids were nonresponsive due to missing information and as a result were rejected.

While the tank is out of service, the City of Columbus’ operations control center will ensure there is no interruption of service for customers served by the water tank. The typical and customary communication methods will be used to convey construction information to any residents and impacted property owners throughout the duration of this work. Recommendation Staff has thoroughly reviewed the bid submitted by Midwest Tank Management. The contractor has not previously performed work for the City of Dublin; therefore, staff made inquiries with references of Midwest Tank Management and received positive feedback regarding their work with previous owners of water tanks being painted by Midwest Tank Management and having similar scopes and budgets. Staff recommends Council approval of Resolution 25-23 accepting as lowest and best the bid of Midwest Tank Management in the amount of $143,300.00 and authorizing the City Manager to enter into a contract with Midwest Tank Management for this Project.
