Treatment Guidance
Treatment guidance provides recommendations for the preservation and repair of individual characteristics of Boulder Fire Station No. 2. Buildings and Structures Rehabilitate, stabilize, and preserve Boulder Fire Station No. 2. • Preserve and repair extant character-defining architectural features in-place including brick masonry on the exterior and interior walls, stone sills, lintels, and copings, asphalt shingle roof and dormers, wood framed windows and doors, and the original hardwood flooring on the second floor. ○ Clean and repoint exterior masonry walls and chimneys as needed using accepted preservation methods detailed by the National Park Service . Replace masonry that is damaged beyond repair; ○ Further investigate the roof and foundation conditions and make repairs based on findings; ○ Remove non-historic coatings on contributing materials. • Preserve, repair, and replace extant architectural finishes to match in-kind. ○ Replace hardwood stairs. ○ Consider restoring original interior finishes to the best extent possible. Conduct further research for original material and finishes that may have been removed during later modifications. ○ Consider restoring original wood lockers in their entirety. ○ Future repair of the staircase should be done with in-kind materials. • Preserve extant structural features in-place. ○ Floor Framing - Investigate the second floor framing by carefully removing some first floor ceiling or second floor flooring finishes in whole pieces so as to protect the historic materials. Once the configuration of the framing is known, a structural analysis can be performed to determine the load capacity of the floor and the extent of strengthening necessary to support the kilns and storage currently located on the second floor. ○ Walls - Rake out deteriorated mortar joints in the walls and chimneys and repoint with a compatible mortar as determined by a mortar analysis of a sample of the original mortar. Note the mortar will require periodic maintenance; Shore the transom window with a steel lintel, slide in a larger bearing plate at either end, pin the masonry near the side of the window, and replace any cracked brick units. ○ Other Structural Elements - Remove any rust from the exterior steel fire escape with a wire brush. Recoat the steel with a zero VOC cold-galvanizing paint. If any members or portions of the deck are corroded beyond structural repair, replace in-kind.
