This file is a comprehensive set of construction drawings (100% construction documents revision) for the remodel of the Golden Spike National Historical Park Visitor Center located in Box Elder County, Utah. The project, identified as PMIS #308441 and Drawing #431, involves remodeling the existing visitor center to support new exhibits across three distinct areas: Area A (Exhibit Space - 4,425 SF for assembly occupancy), Area B (Admin Space - 1,550 SF for business occupancy as an add-alternate), and Area C (Public Restrooms - 373 SF). The prime architect is AJC Architects (Salt Lake City, Utah), with structural engineering by Reaveley Engineers, and mechanical and electrical design by Spectrum Engineers.

The construction documents include detailed site plans, floor plans, reflected ceiling plans, wall sections, building elevations, foundation and footing details, structural reinforcing schedules, and assembly specifications. Key work includes demolition of existing conditions (with asbestos-containing materials identified), new concrete foundation work, interior wall framing with gypsum board finishes, new ceiling systems (suspended acoustical and gypsum board), electrical and mechanical system upgrades, plumbing fixture replacement, fire protection systems, and accessibility upgrades to meet ABAAS standards. The building is classified as Type V-B construction with automatic sprinkler protection per NFPA 13. The drawings establish 189 total occupants (A-3 assembly), require a minimum of two accessible exits per the 2021 International Building Code, and mandate compliance with accessibility standards including accessible parking, restroom facilities, and route requirements. The general contractor is responsible for coordinating with the National Park Service Contracting Officer, field-verifying all existing conditions, maintaining the site during construction, and managing hazardous materials including asbestos removal.
