About this file
This Project Manual details the contract opportunity for the Hermosa North Water Tank Project, prepared by Benesch for the Town of Hermosa in Custer County, South Dakota. The project involves constructing a new glass-fused-to-steel bolted water storage tank with a nominal diameter of 31 feet, a sidewall height of 24 feet, and a capacity of 127,083 gallons. The bid is scheduled for July 18, 2025, at 11:00 AM local time, with a targeted completion date of October 1, 2026. Bidders are required to furnish all necessary labor, tools, materials, and equipment to complete the water tank project, including foundation, tank structure, appurtenances, and associated infrastructure such as water mains, piping, access ladders, and electrical systems.
The project is funded through the Drinking Water Program and has been approved by the South Dakota Department of Agriculture and Natural Resources. The contract includes specific technical requirements for tank construction, including steel sourcing, coating specifications, bolting standards, and installation protocols. Bidders must provide a 5% bid bond or certified check with their proposal, and the successful contractor will be required to provide a 100% performance bond and a 10% warranty bond. Liquidated damages are set at $850 per calendar day for work not completed by the specified completion date. The project emphasizes strict adherence to AWWA (American Water Works Association) standards, with detailed specifications for materials, fabrication, testing, and quality control throughout the construction process.
