Division 06: Wood, Plastics, and Composites for Specifiers

Specifiers engage with MasterFormat Division 06 – Wood, Plastics, and Composites throughout the project lifecycle. Division 06 covers rough carpentry, finish carpentry, architectural woodwork, structural plastics, and composite assemblies—wood-based and engineered framing, millwork, and casework. For specifiers, Division 06 is where core numbering system for project manuals, outline specs, and section schedules.

How Specifiers Use Division 06 – Wood, Plastics, and Composites

Core numbering system for project manuals, outline specs, and section schedules—every deliverable references MasterFormat divisions and titles. Division 06 is one of the divisions that specifiers encounter most frequently in practice. The sections within Division 06 define the products, execution methods, and quality standards that specifiers must reference, review, or author.

Key sections within Division 06 include: - 06 10 00 – Rough Carpentry - 06 20 00 – Finish Carpentry - 06 40 00 – Architectural Woodwork - 06 50 00 – Structural Plastics - 06 60 00 – Plastic Fabrications

These sections shape how specifiers write project manuals or outline specs using masterformat numbers and titles. When section numbers are outdated or inconsistent, the downstream impact on specifiers is immediate: inconsistent spec numbering.

Division 06 in the Specifiers Workflow

Specification writers and in-house specifiers at AECO firms who author, maintain, or use specifications, templates, models, or schedules that include CSI numbers, titles, or classifications. Within this scope, Division 06 plays a specific role:

1. Documentation — Specifiers write project manuals or outline specs using masterformat numbers and titles. Division 06 sections must be correctly numbered and titled in every document that references them.
2. Coordination — Division 06 scope intersects with other divisions on every project. Specifiers need consistent classification to coordinate wood, plastics, and composites work with adjacent trades and disciplines.
3. Quality — maintain and issue office master sections/templates that embed masterformat numbers and titles on client work.

Pain Points Specifiers Face with Division 06

• Inconsistent spec numbering — When Division 06 section references are affected by inconsistent spec numbering, the result is rework, RFIs, or coordination failures that specifiers must resolve.
• Edition confusion across project phases — When Division 06 section references are affected by edition confusion across project phases, the result is rework, RFIs, or coordination failures that specifiers must resolve.

These issues compound across projects. A single incorrect Division 06 section number in a team's template can propagate across every project that uses that template.

Division 06 Cross-References for Specifiers

UniFormat: Division 06 maps to UniFormat B (Shell) for wood framing, C (Interiors) for casework and millwork, and B10 for mass timber superstructure.

OmniClass: OmniClass Table 23 (Products) classifies lumber, engineered wood, and composite products used across Division 06 sections.

Understanding these connections helps specifiers maintain consistency when Division 06 work touches UniFormat elements or OmniClass classifications in their deliverables.

Why Specifiers Need Current Division 06 Data

CSI Dynamic Standards includes Division 06 as part of a connected, edition-aware system—licensed through The Construction Standard. For specifiers, this means always-current section numbers and titles for Division 06, governed cross-references to UniFormat and OmniClass, and edition tracking that prevents referencing obsolete classifications in specifiers deliverables.
