The six deviation categories in Division 02 Existing Conditions

Every issue Deviation Check flags maps to one of six categories. Here is how each appears in Division 02 Existing Conditions 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.

Division 02 submittals are largely method-based, but product substitutions arise for:

Key performance parameters in Div 02 submittals:

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 02 submittals:

Aesthetic requirements are rare in Division 02. Where they appear:

Submittal Package Incompleteness

How Division 02 deviations are graded

Each finding is graded Blocker, Fix and Resubmit, or Note. Division 02 escalation rules:

Missing state abatement contractor license: BLOCKER (legal - cannot legally perform work without it)
Missing EPA NESHAP notification for regulated ACM demolition: BLOCKER (federal regulatory requirement)
HEPA filter efficiency below 99.97%: BLOCKER (worker and public health)
Missing worker training certificates for asbestos or lead: BLOCKER (OSHA enforcement)
Negative air pressure differential below specified minimum: BLOCKER (containment failure risk)
Missing disposal facility acceptance letter: BLOCKER (cannot legally dispose of waste)
Missing CIH/CAC credentials for project monitor: BLOCKER (spec requirement, quality assurance)
Missing HASP: BLOCKER (Cal/OSHA 8 CCR 5192 or OSHA 1910.120 requirement)
Decon unit stages below OSHA minimum (3-stage): BLOCKER (worker health)
Lab accreditation not NVLAP or equivalent: FIX_AND_RESUBMIT (data quality)
Missing waste manifesting plan: FIX_AND_RESUBMIT (regulatory compliance)
Containment boundary differs from spec: FIX_AND_RESUBMIT (scope of work)
PPE respirator APF mismatch for exposure level: FIX_AND_RESUBMIT (worker protection)
Missing emergency response procedure: FIX_AND_RESUBMIT (safety plan incomplete)
