MasterFormat Division 06: Wood, Plastics, and Composites

Division 06 covers rough carpentry, finish carpentry, architectural woodwork, structural plastics, and composite assemblies—wood-based and engineered framing, millwork, and casework. Learn how Division 06 organizes specification sections, connects to UniFormat and OmniClass, and how The Construction Standard provides licensed access to authoritative, edition-aware Division 06 data through CSI Dynamic Standards.

MasterFormat Division 06 organizes the specification sections, cost codes, and work results for wood, plastics, and composites across the construction industry. As part of CSI's consensus-based classification system, Division 06 provides the authoritative structure that specifiers, estimators, contractors, and software platforms use to organize wood, plastics, and composites work.

What Division 06 Covers

Division 06 covers rough carpentry, finish carpentry, architectural woodwork, structural plastics, and composite assemblies—wood-based and engineered framing, millwork, and casework.

This division includes rough carpentry, finish carpentry, architectural woodwork, structural composites, plastic fabrications, and wood treatment.

Division 06 contains multiple levels of sections and subsections that organize this scope into a precise, consensus-based hierarchy. These sections provide the numbering backbone for project manuals, bid packages, cost databases, and BIM models. When teams reference Division 06 consistently, every document from concept estimate to closeout speaks the same language.

Licensed through The Construction Standard, CSI Dynamic Standards includes the authoritative, always-current section numbers and titles for Division 06—searchable, cross-referenced, and edition-aware.

Who Uses Division 06
  • Architects specifying millwork and casework
  • Carpenters and millwork fabricators
  • Mass timber engineers designing CLT and glulam structures
  • Interior designers specifying architectural woodwork

Whether you write specifications, estimate costs, coordinate BIM models, or build software that references wood, plastics, and composites, Division 06 numbers and titles are the shared vocabulary your work depends on.

How Division 06 Connects to Other Standards

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.

These cross-references are maintained by CSI through governed crosswalks—not assembled ad hoc by individual project teams. Through The Construction Standard, licensed access to CSI Dynamic Standards gives teams these relationships so they can navigate between specifications, elements, and lifecycle categories without manual remapping.

Why Edition Awareness Matters

MasterFormat evolves through consensus-based updates. Projects that span multiple years may reference different editions. Division 06 sections may be added, renumbered, or revised between editions. Without edition awareness, teams risk referencing obsolete section numbers, creating specification conflicts, and generating RFIs that delay construction.

Licensed through The Construction Standard, CSI Dynamic Standards gives teams full edition context for Division 06—teams know which edition applies at each project milestone, what changed, and where those changes affect their work.

The Licensing Relationship

CSI—the Construction Specifications Institute—stewards Division 06 as part of MasterFormat. CSI Dynamic Standards includes MasterFormat, UniFormat, and OmniClass as a connected, edition-aware system. The Construction Standard provides licensed access to CSI Dynamic Standards:

  • Always current: Section numbers and titles reflect the latest CSI-approved updates
  • Edition-aware: Teams know which edition applies and what changed between releases
  • Cross-referenced: Governed relationships to UniFormat and OmniClass stay maintained
  • Integration-ready: Enterprise solutions carry Division 06 data into the tools you already use
