About this file

This document is a Technical Questions and Government Response Tracking Sheet for a U.S. Department of the Interior contract (140R6025Q0057) involving replacement of generator air coolers at Marys Lake Powerplant in Larimer County, Colorado. The procurement involves replacing interior components of surface air coolers, with the existing tubes having been last replaced in the 1980s. A site visit is scheduled for 8/15/2025 from 8am to 12pm MST at 2198 Power Plant, Estes Park, CO, and technical questions will be accepted through 08/18/25.

The tracking sheet documents eight technical inquiries from potential vendors, including requests for site visit confirmation, photographs of existing coolers, project background, and technical specifications. Similar past projects include Flatiron air coolers (contract #R17PC00097) and Canyon Ferry air coolers (contract #140R6021D0003). The government has provided additional documentation including specification manuals, drawings of air cooler coils, and photographs to support vendor preparation of quotes for this brand-new replacement requirement.
