Historic Building Envelope Rehabilitation
The Barnum Museum, originally commissioned by P.T. Barnum in 1893 and listed on the National Register of Historic Places, is constructed of brownstone, brick, terra cotta stone and tile, and a combination of wood and steel framing. The building has suffered damage from major storms in recent years and previously underwent a structural stabilization project. Exterior rehabilitation combined with an interior renovation and mechanical upgrades were proposed to restore function to the exhibition spaces. Gale provided visual evaluation of exterior wall systems to identify facade deficiencies, and observed exploratory masonry and interior finish test openings to verify as-built conditions for insulation retrofit options and hygrothermal (WUFI) analysis. We also performed controlled leak testing of balcony roofs and WUFI/ASHRAE 106 analysis of existing and proposed wall assemblies. We then provided peer review of Design Documents’ enclosure-related specifications, details, and drawings for constructability, historic treatment, enclosure continuity, detailing, and performance.
