The scope comprises architectural remodeling and site work across approximately 4,500 square feet of visitor space: interior modifications to expand the building and reconfigure exhibit spaces for new exhibits (Area A, 4,425 SF assembly occupancy), administration area reconfiguration (Area B, 1,550 SF business occupancy, Option 1), and public restrooms (Area C, 373 SF). Work includes demolition of existing conditions with abatement of identified asbestos-containing materials (ACM flooring mastic must be completely removed rather than encapsulated), new concrete foundation work, interior wall framing and gypsum board finishes, new ceiling systems, mechanical and electrical system upgrades, plumbing fixture replacement, fire protection systems per NFPA 13, and accessibility upgrades to meet ABAAS standards.
