Visitor Center Ceiling Installation
NOE - Notice of Exemption
Install a ceiling in the Visitor Center at Empire Mine State Historic Park to provide a barrier to reduce heating and cooling costs. Rafters are currently visible from the interior of the Visitor Center with exposed modern ducting and conduit. Project elements include installing:
- 5/8" fireshield drywall to existing ceiling joists throughout immediate visitor contact area of the Visitor Center.
- R-19 fiberglass insulation above drywall.
- 1 x 12 rough sawn fir boards over drywall to match existing non-historic interior wall covering. Boards will be marked on the non-visible side with an installation date.
Additional ceiling joists supports and cross bracing may be required in certain stress areas, all completely reversible if ever required or desired. No historic wood members will be cut, damaged, or altered other than the use of nails or screws to allow for installation of these materials. Project will save utility costs of up to 50%. No ground disturbance is anticipated.
Project consists of the maintenance, repair and stabilization of a historic resource in a manner consistent with the Secretary of the Interior's Standards for the Treatment of Historic Properties with Guidelines for Preserving, Rehabilitating, Restoring, and Reconstructing Historic Buildings (1995), Weeks and Grimmer; and minor alteration of an existing public facility, involving negligible expansion of use beyond current levels.
