DENA 332037 Eielson Roof Replacement

The National Park Service seeks rehabilitation of the Eielson Visitor Center at Denali National Park and Preserve, Alaska, including roof replacement, interior repairs, and renewable energy system modifications, with proposals due October 20, 2026. This is a Total Small Business set-aside under NAICS 236220 with an estimated value of $5 million to $10 million.

Place of performance is at the Eielson Visitor Center, located 66 miles west of Denali National Park's main entrance via a 2.5-hour park road journey. Work is restricted to 6:00 a.m. to 10:00 p.m., seven days per week during construction season, with operations constrained by seasonal weather, road access conditions, and park environmental and wildlife regulations. The contractor must establish temporary housing and staging facilities at the visitor center or Mile Post 70, provide satellite communication, and comply with strict park protocols including bear-resistant waste management, nesting bird protection, and vehicle cleaning requirements.

The scope encompasses seven contract line items: roof replacement on the main visitor center (CLIN 0001), snow entry mitigation and LED lighting replacement (CLIN 0002), exterior door adjustments and heating modifications (CLIN 0003), hydroelectric system interconnection and plaza reconfiguration (CLIN 0004), interior water-damage repair (CLIN 0005), utility building roof replacement (CLIN 0006), and unit-priced mold remediation (CLIN 0007 at an estimated 3,800 square feet and 4 containment events). The project requires replacement of a living roof system with SBS-modified bituminous membrane and new structural work including selective demolition, fire suppression system modifications, electrical power generation and storage system upgrades, and roofing membrane installation with low-voltage conductance testing. Performance must commence within 10 calendar days of award and complete within 442 calendar days, with liquidated damages of $1,634 per day.

The contractor must perform at least 15 percent of work with its own organization. Davis-Bacon prevailing wage rates apply. Home office overhead is capped at 5 percent and profit at 18 percent for self-performed work, with a combined markup ceiling of 25 percent across all tiers. Performance and payment bonds equal to 100 percent of contract value are required. Proposals must be submitted in two volumes: Volume I addressing project experience, technical approach, management approach, construction schedule, and past performance; Volume II containing pricing with Schedule of Values, bid bond, and representations and certifications. Evaluation uses best-value tradeoff methodology with non-price technical factors collectively significantly more important than price. A mandatory pre-proposal site visit was held August 26, 2026.
