Summary
This **Final Construction Documents Project Specifications** issued by the **National Park Service (NPS) Denver Service Center** in August 2026 defines the requirements for procuring and constructing employee modular housing at Yellowstone National Park, Project YELL 326141.
The project covers three government areas:
- **Canyon Village:** Northwest of Canyon Village along Grand Loop Road and Norris Canyon Road in Wyoming.
- **Northeast Entrance:** Approximately 3.5 miles west of Cooke City, Montana, along U.S. Highway 212.
- **Mammoth:** Near the Mammoth Community Center in Wyoming.
Work will be performed under one prime contract and includes modular residential buildings, site grading, roads, drainage, electrical and telecommunications systems, potable water, fire suppression, sanitary sewer, stormwater utilities, paving, concrete, retaining walls, landscaping and restoration, building envelope, finishes, appliances, casework, and related site electrical infrastructure.
The specifications are organized across Divisions 01–33 and include appendices covering categorical exclusion requirements, endangered-species protections, geotechnical reports, Wyoming public works standards, and electric-service authorization.
The project requires a single construction phase, limited use of project sites within designated disturbance limits, approval of staging and storage areas, protection of existing vegetation and whitebark pine, and coordination to preserve public, government, and emergency access.
No government-furnished materials are anticipated. Equipment entering the Park must undergo required NPS inspection and cleaning, and construction materials must be sourced from an inspected gravel pit.
Housing camps are prohibited at Mammoth and the Northeast Entrance but may be established near Canyon Village at 15 assigned trailer sites with electric, water, and sewer hookups. The stated 2026 trailer-site rental rate is $485.74 per month; the contractor is also responsible for electricity and compliance with Park rules.
Oversize or overweight hauling requires a travel-control plan and haul route for approval. The contractor must also address seasonal road closures, snow removal, bridge restrictions, identification and gate-pass requirements, and state and Park load restrictions.
Environmental, safety, public-use, and operational controls are extensive. Contractor personnel and families must attend NPS bear and wildlife orientations.
Food, garbage, and other attractants must be secured in buildings or vehicles. Contractor waste may not be placed in NPS containers, and pets and bird feeders are prohibited.
Mishandling bear attractants may result in citations, fines, and contractor-paid management actions.
Work is generally limited to 8:00 a.m.–5:00 p.m., Monday through Friday. Advance approval is required for nights, weekends, holidays, or alternate hours.
Utility locating and coordination are mandatory before excavation. Interruptions to occupied facilities require at least four business days’ notice, written permission, and temporary service arrangements, with typical shutdown limits of 24 hours from October through April and 12 hours from May through September.
The contractor must use NPS project-management software, maintain visitor and Park-staff safety, implement tree protection and temporary fencing, minimize nighttime noise and artificial light, comply with wetland and Ute ladies’-tresses protections, report specified wildlife observations, and follow conservation measures for grizzly bears, Canada lynx, yellow-billed cuckoos, whitebark pine, and Suckley’s cuckoo bumble bee.
