Codes, Standards, Specifications, and Facility Security Administration
Know the hierarchy
Codes set minimums; standards provide test methods and installation criteria; specifications tell the contractor what to buy and install. Know the roles: IBC and NFPA 101 for egress and life safety, NFPA 80 for fire door assemblies, NFPA 72 for fire alarm, ADA Standards and ICC A117.1 for accessibility, and ANSI/BHMA A156 for hardware performance. The authority having jurisdiction (AHJ) interprets and enforces. Specifications use CSI MasterFormat: Division 08 for openings (doors, frames, hardware) and Division 28 for electronic safety and security (access control, fire alarm). Submittals, shop drawings, samples, substitutions, RFIs, closeout documents, and O&M manuals are administrative controls that protect the owner.
Traps
Candidates confuse code minimum with owner standard, or forget that the AHJ has final say. Or equal is not automatic; substitutions require approval. Naming a proprietary product without an equal clause can create a procurement problem. Field modifications to labeled fire doors can void the label, and NFPA 80 requires annual fire door inspections. Misplacing access control hardware in Division 08 instead of Division 28 is a common specification error.
Worked example
An owner wants card readers added to a rated corridor door. Check IBC and NFPA 101 free egress; NFPA 80 listing and label; fire alarm release; ADA operating force; Division 28 specification section and access control policy; and AHJ approval. Rule of thumb: if a change affects egress or a fire label, the AHJ and the listing come before the catalog number.
