The six deviation categories in Division 08 Openings
Every issue Deviation Check flags maps to one of six categories. Here is how each appears in Division 08 Openings submittals, with the full guide one click away.
Manufacturer or Product Substitution
Blocker The submittal proposes a different manufacturer or product than the spec names, without an approved or-equal or substitution request.
Div 08 specs name door, frame, hardware, and glazing system manufacturers. Look for:

Performance Specification Gap
Blocker A measurable performance property in the submittal (rating, capacity, tolerance, efficiency) does not meet what the spec requires.

Missing Certification or Compliance Documentation
Fix and Resubmit A required listing, test report, certification, or compliance document is absent from the submittal package.
Required certifications in Div 08 submittals:

How Division 08 deviations are graded
Each finding is graded Blocker, Fix and Resubmit, or Note. Division 08 escalation rules:
- Fire-rated assembly listing missing or mismatched: BLOCKER (life-safety, NFPA 80, IBC)
- Hardware function mismatch on fire/egress door: BLOCKER (life-safety, means of egress)
- Safety glazing omission where code requires: BLOCKER (building code, injury risk)
- U-value or SHGC exceeding energy code maximum: BLOCKER (ASHRAE 90.1/IECC violation)
- Wind load rating below design pressure: BLOCKER (structural, building code)
- Missing ADA compliance on accessible opening: BLOCKER (ADA/ANSI A117.1 requirement)
- Exit device missing or wrong type on required egress door: BLOCKER (IBC means of egress)
- Door/frame gauge lighter than spec: FIX_AND_RESUBMIT (durability, security)
- Hardware finish mismatch: FIX_AND_RESUBMIT (aesthetic)
- Glass VLT or appearance mismatch: FIX_AND_RESUBMIT (aesthetic, architect's design intent)
- Missing keying schedule: FIX_AND_RESUBMIT (coordination, cannot finalize without it)
- Curtain wall deflection exceeds spec limit: BLOCKER (glass breakage risk)
- Missing curtain wall structural analysis: BLOCKER (cannot verify adequacy)
