This historic tower built in the late 1920s underwent a conversion from commercial space to a mixed-use development with residential and business spaces. As a result of alterations and a new mechanical plant installation, structural steel elements supporting the upper level dome were left unprotected. Holmes Fire demonstrated that the intent of the City of New York Building Code was met without the addition of fire protection to the structural steel. A waiver was issued by the New York City Department of Buildings alleviating the need for any additional fire protection measures. This brought considerable savings to the project, particularly economizing time and cost during construction.
