Sources Sought Notice

The National Park Service Denver Service Center is seeking to procure construction services to address contaminated debris, replace a maintenance storage facility, and resolve road drainage issues at Sunset Crater Volcano National Monument in Arizona. This Sources Sought Notice represents the market research phase prior to formal solicitation, with the NPS conducting an assessment to determine potential small business or socio-economic set-asides and evaluate contractor capabilities. Key qualifications include federal construction experience, appropriate licensing and permitting compliance, bonding capacity, remote area construction expertise, and the ability to self-perform a significant portion of the work. The evaluation will consider contractor backgrounds, small business certifications (EDWOSB, HUBZone, SDVOSB), subcontractor utilization plans, and demonstrated experience in similar projects within remote or geographically constrained areas. Interested contractors must submit the Sources Sought Survey Questionnaire by November 18, 2025, at 2:00 PM Mountain Time to James Waller and Daryl Hawkins; the formal Request for Proposals is anticipated for release in December 2025 through January 2026.

The project carries no specific set-aside designation at this stage, though the NPS is actively evaluating potential designations as part of the market research. The estimated contract value ranges between $1 million and $5 million, awarded as a single Firm-Fixed-Price contract with 188 calendar days for performance completion, potentially including winter construction activities. The project falls under NAICS code 236220 (Commercial and Institutional Building Construction) with a $45 million size standard and PSC code Y1EB (Construction of Maintenance Buildings). Notable project constraints include limited staging facilities at the park, a location 15-20 miles from suppliers and lodging, and the requirement to maintain park operations for visitors throughout the construction period, necessitating careful scheduling and coordination to minimize operational disruption.
