How to Use This Calculator
  1. Enter Correct UL system (0/1), Proper fill depth (0/1), and Annular space OK (0/1).
  2. Set Surface finish OK (0/1), Labels installed (0/1), and Documentation on file (0/1).
  3. Adjust Installer certified (0/1), Total penetrations as needed.
  4. Review the Inspection score (0-100) result.
  5. Use Passes inspection (0/1) and Deficiencies found to inform your decision.

What each input means

Correct UL system (0/1)
Installed system matches the listed UL system design.
Proper fill depth (0/1)
Sealant/fill material at correct depth per listing.
Annular space OK (0/1)
Gap between penetrant and opening is within listing limits.
Surface finish OK (0/1)
Smooth finish, no voids, cracks, or missing material.
Labels installed (0/1)
Firestop identification labels affixed at each location.
Documentation on file (0/1)
Inspection reports and UL system details documented.
Installer certified (0/1)

Total penetrations
Number of penetrations being inspected.

What each result means

Inspection score (0-100)
Weighted quality score.
Passes inspection (0/1)
1 = passes, 0 = fails (requires correct system, fill depth, score >= 70).
Deficiencies found
Total number of failed criteria.
Critical deficiencies
System mismatch or fill depth issues.
Remediation hours
Estimated labor hours to fix all deficiencies.
Remediation cost ($)
Estimated cost at $85/hr labor rate.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Correct UL system (0/1) = 1, Proper fill depth (0/1) = 1, Annular space OK (0/1) = 1, Surface finish OK (0/1) = 1 = 8 input(s) provided
  2. Calculate Inspection score
    100 = 100
  3. Calculate Passes inspection
    Passes inspection
    1 = 1
  4. Calculate Deficiencies found
    Deficiencies found
    0 = 0
