E2. 2nd Ave W Water Main Replacement Project Bid Recommendation MemoCITY 7tialM. KALISPELL MEMORANDUM To: Doug Russell, City Manager Cc: Susie Turner, PE — Public Works Director From: Patrick Jentz, PE Engineer 2 Re: 2nd Ave W Water Main Replacement Project Meeting Date: March 15, 2021 BACKGROUND: 2nd Ave W Water Main Replacement Project is located in the central area of town and replaces over two blocks of 1920 era water main sections and appurtenances. This replacement and rehabilitation project was identified as part of the 2018 Water Facility Plan - Risk Assessment due to the high likelihood/high consequence factors for a main break. The project includes furnishing labor, materials, and equipment required to replace an existing fl- inch cast iron water main with approximately 807 linear feet of 8-inch PVC water main. Also included in the project are water valves, fire hydrants, water service connections, paved surface, sidewalk and landscape restoration. Additive Alternative 1 (AA I) was included to complete the replacement of the old cast iron water main and extends construction across Center Street into the Center Mall approached area. AA includes approximately 115 linear feet of 8-inch PVC water main as well as additional valves, fire hydrant and connections to the existing 1984 PVC water main. BIDDING RESULTS: Bids were received and opened on March 3, 2021 at 3:30 pm. Four responsive bids were received and are summarized below. Contractor Base Bid Additive Alternate 1 AGC Inc $374, 477.00 $43, 311.00 Whites Civil Contracting $394,395.00 $51,770.00 Western Municipal $398,332.00 $58,925.00 Sandry Construction $423,274.00 $45,194.00 Engineer's 2021 Estimate $364,776.00 $45,286.00 AGC Inc. was the low bid. References were checked and AGC Inc. was found to be a qualified contractor that was good to work with on other projects. FISCAL EFFECTS: FY 21 Water Fund allocation of $302,000 was budgeted to support the construction of the 2nd Ave W Water Main Replacement Project. The budgeted amount was established from winter/spring 2020 estimates and did not take into consideration the higher construction costs due to the pandemic and increased construction demands in the valley. The $115,788 cost difference between the project bid price and project budget will be supported by reprioritizing the design and construction schedule for the Buffalo Hill Tower Flow Control Upgrade Project. Preliminary engineering for the new upper zone elevated tank identified the need to consider and incorporate flow control for the existing tower. As such, the design and Page 1 of 2 construction for a flow control at the Buffalo Hill water tower will be incorporated into the 1 MG Elevated Storage Tank and Well Project and will not be performed as anticipated in FY 21. To summarize, the 2nd Ave W Water Main Replacement Project will be funded through the following sources: 1. Water Operations Fund: "2nd Ave W Water Main Replacement Project" line item # 5210-447-430550-958 - $302,000. 2. Water Operations Fund: `Buffalo Hill Flow Control Upgrades" line item # 5210-447- 430550-937 - $140,000.
