Summary
This **Questions and Answers amendment issued by the National Park Service (NPS)** addresses bidder inquiries and clarifies proposal, permitting, scheduling, licensing, utilities, site logistics, materials disposal, and construction requirements for work at Yellowstone National Park’s Mammoth Hot Springs, Canyon Village, and Northeast Entrance sites.
NPS confirmed that all prime contractors and subcontractors must comply with applicable Wyoming, Montana, and local licensing requirements, while NPS will administer or obtain identified Government-furnished permits and approvals. An Oracle Primavera P6 schedule is acceptable if submitted in the required Gantt-chart format. The Product Binder is a separate deliverable from the 15-page Concept Narrative and will establish contractually binding minimum quality baselines. One comprehensive organizational chart may satisfy both organizational-chart requirements.
Only the Site Safety and Health Officer and Quality Control personnel may be dual-hatted, although multiple individuals may be required to cover concurrent activities at separate locations. The official deadline for pre-proposal questions is September 3, 2026, and a fillable Past Performance Questionnaire was provided.
The responses also establish important pricing and site-condition assumptions. NPS will provide up to 10,000 gallons of water per day at selected Mammoth and Canyon hydrants at no cost, subject to backflow-prevention and possible metering requirements, but no water will be provided at Northeast Entrance.
Contractors must arrange and pay for legal off-site disposal of woody slash, stumps, brush, and other green waste; they may not rely on NPS salvage pits for disposal. Staging and stockpile areas are limited to those shown on Sheets C2.11–C2.13, with no additional in-park areas assumed for pricing.
At Northeast Entrance, offerors should assume the four-plex sanitary service discharges to SSMH-D1 and that no reconnection work is required. For the approximately 300-foot existing 8-inch sanitary pipe at Mammoth, the contractor may remove some or all of it and dispose of it off site at no additional cost, but any remaining pipe must be fully grouted.
NPS also stated that the contractor must remove unneeded concrete washout material and pay for any required repaving. Attached project reports and estimated cut-and-fill quantities are provided for proposal use but are unverified and used at the offeror’s risk.
Additional clarifications confirm that RV camp pricing is informational and paid directly to the park rather than included in the contractor’s cost proposal. Applicable Buy America or construction-material trade-agreement requirements must be followed for the modular homes.
Contractors using available Canyon RV sites for construction must coordinate impacts through the NPS process, while NPS otherwise coordinates camper relocations based on the contractor’s schedule. NPS will provide available electronic civil design files after award, with the issued contract drawings remaining controlling.
NPS has not yet answered whether additional staging or laydown areas near the three sites will be available; that issue is reserved for a future amendment.
