spokesperson with the New York State Office of Parks, Recreation, and Historical Preservation. SHPO considered Hughes Associates’ recommendations, which included features that would make the overall structure—the 154-foot [47-meter] pedestal, as well as the 151foot [46-meter] statue—fully compliant with the city’s building code. SHPO determined that some of the proposals would have had more-thanminimal impacts on the monument’s “historic fabric,” according to Ferreira, including the statue’s copper sheeting—just .09 inch [2.3 millimeters] thick, or about the thickness of two pennies placed together—as well as the internal framework supporting the structure and the double helical stairs
in the statue leading to the crown. “To make [the stairs in the statue] fully code compliant, you’d have to remove them and replace them with two enclosed stairs within the body of the statue,” says Ferreira. “That wasn’t practical or desired.” A similar process was used to determine the level of fire and life safety that would be achieved throughout the structure, including the areas that were particularly sensitive to “historic fabric” considerations. The Hughes recommendations included computer models addressing life safety hazards, fire protection options, and means of egress, Ferreira says, so that designers were always aware of the effects that fire safety and historic preservation had on each other.
SHPO regarded other aspects of the monument as less integrated with its historic fabric. For example, the main elevator and staircases in the monument’s pedestal that lead to the pedestal’s observation platform were last replaced in the 1980s for the monument’s centennial in 1986 and were not up to current building and life safety codes. Upgrading these elements would require the removal of concrete that was poured during the statue’s construction in the 1800s. “It was viewed during the evaluation process that certain historical aspects… [such as the concrete] in the pedestal weren’t as important as what was in the statue itself,” Ferreira says. Guidelines for such decision making are at the core of NFPA 914, Fire
Based on its size and aBility to have an occupied floor 75 feet (23 meters) aBove grade, the monument is considered a high-rise structure and adheres to code provisions for such structures.
