Install buried filtered water tank IAW constructio

The National Park Service is soliciting bids for the installation of a 50,000-gallon buried filtered water tank at Haleakala National Park in Maui, Hawaii, along with associated infrastructure including distribution piping, fittings, and site improvements. This competitive procurement includes optional bid items for a vehicle turnout with either gravel or asphalt surface and exterior tank coatings. The project requires contractors to construct a cast-in-place concrete water tank that will be partially buried with 2.5:1 earthen slopes, designed to provide additional water storage for fire flow and drought conditions while quickly replenishing the potable domestic water supply. A mandatory site visit was required on June 27, 2025, and all questions had to be submitted in writing by July 3, 2025. The current proposal due date is July 25, 2025, at 12:00 PM Mountain Time, with a virtual bid opening scheduled for July 28, 2025, and awards will be made based on the lowest responsive and responsible bidder meeting all technical specifications.

This procurement is designated as a 100% Small Business Set-Aside under NAICS code 237110 with a $45 million size standard, and the estimated project magnitude ranges between $1 million and $5 million. No incumbent contractors are mentioned in the solicitation documents. The contract performance period allows 7 calendar days for commencement and 240 calendar days for completion, with the overall period of performance running from August 1, 2025, to March 29, 2026. The work will be performed at Haleakala National Park's summit at approximately 7,300 feet elevation, where the new tank will be located northwest of existing slow sand filter tanks. The project involves complex engineering considerations including seismic design requirements, excavation of hard basalt bedrock, and integration with the park's existing rainwater collection and potable water storage system.
