This is Amendment 0008 to Request for Proposals (RFP) No. 140P2025R0082 for a construction project administered by the National Park Service (NPS) Denver Service Center Contracting Division. The amendment, issued January 16, 2026, is not extended and maintains the proposal submission deadline of February 3, 2026. The amendment provides responses to contractor questions regarding the construction project requirement and solicitation, with detailed responses available in the attached "B09_Amd8_QR Tracker - DEVA 318717.xlsx" file.
The amendment includes revised specification addendums and drawing sheets based on comments from NPS Public Health Consultants following their review of stamped and sealed construction documents. The revisions address multiple construction disciplines including chemical feed systems, wastewater pumping stations, gravity sewer pipelines, manhole rehabilitation, water utility valves and hydrants, potable water supply wells, plumbing pumps, and aluminum overhead doors. Offerors must acknowledge receipt of this amendment prior to the February 3, 2026 proposal deadline by completing items 8 and 15 on the form, acknowledging receipt on each copy of the offer submitted, or by separate written communication referencing the solicitation and amendment numbers. The contracting officer is Amber Hughes (amber_hughes@nps.gov) and the contract specialist is Abigail Villareal (abigail_villareal@nps.gov). Questions were due November 30, 2025, and this is the eighth amendment to the original RFP issued September 30, 2025.
