Cyclic replacement of lagoon liners

The National Park Service Intermountain Region is seeking a contractor to perform cyclic repair of lagoon liners at Chaco Culture National Historical Park in Nageezi, New Mexico. The project involves repairing damage to wastewater lagoon liners in two cells (Southeast and Northeast) that were damaged by a 2024 windstorm and subsequent UV degradation, requiring replacement of approximately 13,750 square feet of 45 mil reinforced polypropylene geomembrane liner on south-facing berms and corners. Contractors must submit a quote package including a technical capabilities statement (maximum 2 pages), three past performance references from similar projects within the last four years, and pricing for the specified contract line items. The evaluation will be conducted on a best value basis considering price, technical capability, and past performance factors. A mandatory site visit is scheduled for July 29, 2025 at 10:00 AM Mountain Time, and all quotes must be submitted via email to Brian Dankmeyer by August 21, 2025.

This opportunity is designated as a Total Small Business set-aside under NAICS code 221320 (Sewage Treatment Facilities) with a size standard of $35.0 million. The contract will be a firm fixed-price agreement with a period of performance from September 22, 2025 to November 21, 2025, allowing 60 calendar days for completion after notice to proceed. The government anticipates issuing the notice to proceed 30 calendar days after contract award, with onsite work limited to 30 calendar days and restricted to weekday hours between 8 AM and 5 PM.
