This sheet is a continuation of the A1.04 sheet...
This sheet is project-specific and only included when rated wall or floor assemblies require penetration protection per building code and manufacturer standards. It will not be used on all projects — please include only when applicable.
What’s Included (when required):
UL-Listed or Manufacturer-Approved Penetration Details for:
Pipes, ducts, and conduit through fire-rated walls/floors
Electrical boxes and recessed fixtures
Sleeved or grouped penetrations with intumescent sealants or wrap systems
Reference Tags that coordinate with assembly tags on wall types and floor plans
Annotations and Notes clarifying sealant systems, caulking, fire collars, and installation requirements
Instructions:
Confirm with your PM / SD whether this sheet is needed based on project type (multifamily, mixed-use, etc.).
Penetration details must match approved UL systems or manufacturer submittals provided by MEP consultants.
Do not reuse old details unless verified for current UL systems and project-specific conditions.
If included, ensure correct titleblock is applied and sheet is placed in numerical drawing order.
Why it Matters:
Rated penetrations are a frequent point of inspection failure and must be documented clearly to avoid field issues. This sheet ensures life safety compliance and communicates expectations to trades and inspectors.
