CSI Division
Division 06: Wood, Plastics, and Composites submittal deviations
What changes between a Division 06 Wood, Plastics, and Composites spec section and the sub's submittal, why it matters, and how each deviation is graded.
Short answer
Division 06 Wood, Plastics, and Composites submittals deviate most often on product substitutions, performance ratings, and missing certifications. Deviation Check flags every difference from the spec and grades it a Blocker, Fix and Resubmit, or Note.
Division 06 covers wood, plastics, and composite products in commercial construction: rough carpentry, finish carpentry, heavy timber, glulam, CLT/mass timber, architectural woodwork, wood trusses, structural composite lumber, plastic fabrications, FRP, and wood treatment/preservation.

The six deviation categories in Division 06 Wood, Plastics, and Composites
Every issue Deviation Check flags maps to one of six categories. Here is how each appears in Division 06 Wood, Plastics, and Composites 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.
Wood and composite specs name basis-of-design manufacturers and product lines. Submittals proposing alternates must provide "or equal" documentation. Look for:

Performance Specification Gap
Blocker A measurable performance property in the submittal (rating, capacity, tolerance, efficiency) does not meet what the spec requires.
Key performance parameters in Division 06 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 Division 06 submittals:
Aesthetic Deviation
Fix and Resubmit A visible attribute (color, finish, texture, profile) differs from the spec or the architect-approved sample.
Applies primarily to architectural woodwork and exposed structural wood:

Detail or Installation Mismatch
Fix and Resubmit The submitted detail, dimension, anchorage, or installation method differs from what the spec or drawings require.

Submittal Package Incompleteness
Fix and Resubmit A required submittal element (cut sheet, schedule, calculation, sample) is missing, leaving the package unreviewable as submitted.

How Division 06 deviations are graded
Each finding is graded Blocker, Fix and Resubmit, or Note. Division 06 escalation rules:
- Wood species or grade below structural design requirements: BLOCKER (structural capacity not met per NDS)
- Missing ICC-ES ESR report for engineered wood product: BLOCKER (no verified basis for code compliance)
- FRT product not listed for intended application: BLOCKER (fire-safety, code violation per IBC)
- Moisture content exceeds specified limit for enclosed conditions: BLOCKER (shrinkage, fastener withdrawal loss, decay risk)
- Missing truss design calculations or sealed drawings: BLOCKER (IBC requires licensed PE design per TPI 1)
- Preservative treatment retention below AWPA minimum for specified use category: BLOCKER (premature decay, structural failure)
- Connector load rating below design load: BLOCKER (structural connection failure)
- CLT panel layup or grade below structural design requirements: BLOCKER (does not meet ANSI/APA PRG 320 stress values)
- AWI quality grade below specification: FIX_AND_RESUBMIT (aesthetic/workmanship, not structural)
- Wood species stain color mismatch for architectural woodwork: FIX_AND_RESUBMIT (aesthetic, architect approval needed)
- Missing preservative treatment certificate: FIX_AND_RESUBMIT (treatment may be correct but documentation absent)
- Veneer cut or matching method differs from spec: FIX_AND_RESUBMIT (aesthetic, requires architect review)
- Missing FSC/PEFC chain-of-custody documentation: FIX_AND_RESUBMIT (LEED credit, not life-safety)
- Sheathing nailing schedule differs from shear wall design: BLOCKER if lateral system, FIX_AND_RESUBMIT if non-structural

Frequently asked questions
What are the most common deviations in Division 06 Wood, Plastics, and Composites submittals?
The most common are product or manufacturer substitutions, performance specification gaps, and missing certification or compliance documentation. Deviation Check sorts every finding into one of six categories.
How are Division 06 deviations graded?
Each finding is graded Blocker (resolve before approval), Fix and Resubmit (correct and re-send before fabrication or install), or Note (acceptable with a comment).
