The Process

 The submittal review process ensures that all proposed firestop materials and systems comply with the approved construction documents and applicable code requirements. Under the IFC, inspectors verify that listed and tested systems (such as UL or Intertek designs) are submitted for each penetration and joint condition. This includes confirming manufacturer data, system listings, engineering judgments (if applicable), and compatibility between materials. The goal is to identify discrepancies early, preventing improper installations and costly corrections during construction. 

 Documentation review focuses on validating that all required records are complete, accurate, and code-compliant before and during installation. This includes reviewing product data sheets, safety data sheets (SDS), installation instructions, and approved submittals. The IFC emphasizes maintaining traceable documentation that demonstrates compliance with tested and listed systems. Inspectors ensure that documentation aligns with field conditions and that any deviations are properly addressed through approved engineering judgments. 

 Assembly review involves evaluating the specific wall or floor assemblies in which firestopping will be installed. Inspectors confirm that the construction type, fire-resistance rating, and configuration of the assembly match the tested system requirements. This includes verifying substrate materials, thickness, framing, and any unique conditions such as fluted decks or shaft walls. Per IFC intent, firestop systems must be installed within assemblies that match their tested design—any variation can invalidate the fire-resistance rating. 

 System review ensures that the selected firestop system is appropriate for the specific penetration or joint condition encountered in the field. Inspectors confirm that the system addresses the correct variables, including annular space, penetrating item type, movement capability (for joints), and required fire rating. The IFC requires that only listed and tested systems be used unless supported by a valid engineering judgment. This step ensures that the correct system is chosen before installation begins. 

 The inspection phase is the core of the third-party firestop process, involving field verification of installed systems. Inspectors observe installations for compliance with approved submittals, manufacturer instructions, and tested system details. This includes verifying proper backing materials, sealant depth, annular space, and overall workmanship. The IFC requires periodic inspections to ensure that firestop systems are installed correctly and continuously throughout the project, maintaining the integrity of fire-resistance-rated assemblies. 

 Reporting provides formal documentation of inspection findings and compliance status. Inspectors generate detailed reports outlining inspected locations, systems used, deficiencies observed, and corrective actions required. The IFC requires that these reports be provided to the building official and project stakeholders to demonstrate compliance. Clear, organized reporting ensures accountability, facilitates timely corrections, and serves as a permanent record for life safety systems within the building.
