Project Description:
The National Park Service (NPS) is seeking interested and qualified contractors for a construction project located at the Eielson Visitor Center (EVC) within Denali National Park and Preserve, Alaska. The project site is extremely remote¿approximately 240 miles northeast of Anchorage and an additional 66 miles west of the park entrance via a restricted park road, requiring approximately 2.5 hours of travel from the entrance.
The project consists of comprehensive rehabilitation and infrastructure improvements to the EVC and associated utility building. Major scope elements include replacement of the existing living roof systems with new assemblies, removal of exterior stairs, and demolition of select interior and exterior architectural, structural, mechanical, and electrical components. Work also includes upgrades to building interiors and exteriors to improve accessibility and bring the facility into compliance with the 2024 International Code Council (ICC) family of codes.
In addition, the project includes renewable energy system improvements, including repairs to the existing hydroelectric generation system and full replacement of the facility¿s photovoltaic (PV) system with a new standalone array.
Due to the remote location, construction will require contractor-provided staging and housing near Eielson Visitor Center (Mile 66¿70). Access is constrained by seasonal road conditions, limited snow removal (typically May through mid-October), and travel restrictions along the park road, including reduced speeds, narrow gravel sections beyond Mile 15, and operational controls for wildlife and traffic.
The project will be delivered under a single prime construction contract and will require contractors with demonstrated experience in remote logistics, cold climate construction, sustainable systems, and complex rehabilitation of occupied or sensitive federal facilities. The project is required to achieve substantial completion within a single construction season, constrained by limited site access typically occurring between May and mid-October.
