DATE: September 30, 2024 JOB NO.: 0387.058 memo RE: Lower Zone Storage Tank Replacement Reservoir 1 Recommendation of Award ❑Urgent El For Review ❑Please Comment ❑Please Reply ®For Your Use Background: The Lower Zone Storage Tank Replacement Project Reservoir 1 generally consists of the construction of a new 2.5 million gallon (MG) prestressed concrete storage reservoir located on Buffalo Hill in Kalispell. The project includes demolition of the existing 1.7 MG reservoir, site preparation, utility modifications, and construction of the new reservoir. The basis for the recommendation to install a new tank was determined in an alternative analysis report completed in April 2023. Bidding Results: Bids were received on September 26, 2024 and read aloud at 2:00 pm at City Hall. Two responsive bids were received from Preload, LLC ("Preload") of Louisville, KY and DN Tanks, LLC ("DN Tanks") of Grand Prairie, TX. Below is a summary of bid amounts for each bid schedule and additive alternate. Schedule 1 is for the 2.5 MG tank and Additive Alternate A is to replace the 20" transmission main from the new tank to the new Buffalo Hill Well. Bid totals are listed low to high and summarized as follows: Schedule 1: Additive Contractor Reservoir 1 Alternate A Total Bid Price (2.5 MG) Preload, LLC $6,242,350 $181,650 $6,424,000 Louisville, KY DN Tanks, LLC $6,320,212 $273,349 $6,593,561 Grand Prairie, TX Engineers Estimate $7,138,200 $169,650 $7,307,850 Morrison-Maierle, Inc. The low bid of $6,424,000 is below the Engineer's Estimate by $883,850. Morrison-Maierle does not have any previous work experience with Preload, but has worked on projects with their site work contractor, Sandry Construction of Bigfork, MT. Preload's qualification questionnaire shows they have completed recent projects of similar size and scope and are qualified to complete this project. Two references were contacted and indicated they had no concerns with Preload constructing this type of project. Since this is a specialized rehabilitation project, the number of qualified contractors is limited and receiving only two bids was not unexpected. Page 1 Lower Zone Storage Tank Replacement Reservoir 1 Recommendation of Award ®` Morrison „Maierle Summary of Budgeted Funds The project is funded through a combination of local funds and a State Revolving Fund Loan. The construction budget is as follows: Construction: $6,424,000 Contingency: $963,600 Total Construction Budget $7,387,600 Potential Cost Saving Alternatives Potential cost saving alternatives could include the following: • Remove Additive Alternate A ($169,650) from the project Award Options The City has the options available in terms of awarding a contract for this project: 1. Award Schedule 1: Reservoir 1 + Additive Alternate A in the amount of $6,424,000 2. Award Schedule 1: Reservoir 1 in the amount of $6,242,350 3. Reject all bids and re -bid the project at a later date. Recommendation Morrison-Maierle believes that the low bid amount of $6,424,000 is a competitive bid and that the City is not likely to see a lower bid should the project be bid at a later date. Based on the qualification information submitted with their bid and reference checks, Preload is competent and capable of completing the proposed work. If considered appropriate by the City, it would be the recommendation of Morrison-Maierle to award the contract to Preload, LLC.
