This report was prepared to provide an explanation of the prescriptive-based code approach for the Neutron Generator Production Facility’s (NGPF) structural fire protection and construction classification determinations based upon the original code-of-record (1991-UBC) and current International Building Code (2012-IBC) requirements. The code approach presented in this report included a determination of the required construction type in accordance with the 2012-IBC. Through the evaluation of the record design drawings and subsequent site surveys, a determination was made of the existing types of materials used to construct the columns, beams, floor assemblies, roof assembly, and exterior and interior walls and partitions. A summary is provided for the fire resistance requirements of the different elements of the building. In addition, a determination was made in regards to the fire resistance hourly ratings of the columns, beams, floor assemblies, roof assembly, exterior walls, interiors walls and partitions, door openings, joints and penetrations. Through design evaluation, site survey, code verification, and review of record documents, the actual construction classification (Type II-B) was confirmed to be compliant with the 2012-IBC.
