MasterFormat Division 32 – Exterior Improvements in the Design Development Phase

Start with [CSI MasterFormat Division 32: Exterior Improvements](/MasterFormat-division-32-exterior-improvements) for the broad scope and coordination boundaries. This page addresses the narrower design development phase intent.

Division 32 Activities During Design Development

Design development refines schematic decisions into specific systems, materials, and assemblies. This is where UniFormat elemental scope transitions to MasterFormat specification sections—a critical handoff that determines whether design intent survives into construction documents. CSI Dynamic Standards governs these crosswalks so the transition is traceable and consistent. For Division 32 specifically, the design development phase involves focused work on exterior improvements scope, products, and execution requirements. Insert authorized MasterFormat numbers and titles as discipline sections are developed. Keep reference standards coherent across sections with edition awareness.

Key activities for Division 32 during design development include:

• Map UniFormat elements to specific MasterFormat specification sections — as it relates to exterior improvements sections and the products, methods, and quality standards they define
• Insert authorized MasterFormat numbers/titles for discipline sections — as it relates to exterior improvements sections and the products, methods, and quality standards they define
• Update cost models to bridge UniFormat elemental and MasterFormat section formats — as it relates to exterior improvements sections and the products, methods, and quality standards they define

Each of these activities requires current, accurate Division 32 section numbers. When teams reference outdated or incorrect section numbers during design development, the errors propagate into every subsequent phase.

Division 32 Sections Referenced in Design Development

The following Division 32 sections are commonly referenced during design development work:

• 32 10 00 – Bases, Ballasts, and Paving
• 32 12 00 – Flexible Paving
• 32 13 00 – Rigid Paving
• 32 14 00 – Unit Paving
• 32 30 00 – Site Improvements

These sections define the scope boundaries, product requirements, and execution standards for exterior improvements work. During design development, these section references appear in drafted specification sections with authorized numbering and must be consistent with the project manual.

Design Development Deliverables That Reference Division 32

Project teams produce or consume these deliverables during the design development phase, many of which directly reference Division 32 sections:

• Drafted specification sections with authorized numbering

Every deliverable that references Division 32 must use current section numbers and titles. A single incorrect section reference in a design development deliverable can trigger RFIs, scope disputes, or change orders during construction.

Common Issues with Division 32 During Design Development

• Design intent lost in the UniFormat-to-MasterFormat transition — When this occurs with Division 32 references during design development, the result is rework, coordination failures, or documentation that contradicts the project manual.
• Specification sections drafted with outdated section numbers — When this occurs with Division 32 references during design development, the result is rework, coordination failures, or documentation that contradicts the project manual.
• BIM elements not classified for lifecycle use — When this occurs with Division 32 references during design development, the result is rework, coordination failures, or documentation that contradicts the project manual.

These issues are compounded when Division 32 sections must coordinate with other divisions. This division includes flexible paving, rigid paving, curbs and gutters, unit paving, site improvements, planting, irrigation, and fences and gates. The more trades and disciplines that touch Division 32 scope during design development, the higher the cost of classification errors.

Cross-Standard Connections for Division 32 in Design Development

UniFormat: Division 32 maps to UniFormat G (Sitework)—the exterior improvement elements that complete the site.

OmniClass: OmniClass Table 23 (Products) classifies paving materials, plants, and irrigation equipment; Table 12 (Spaces) includes exterior spaces.

During the design development phase, these cross-references ensure that Division 32 specifications align with element-level classifications and lifecycle tags. Teams who rely on landscape architects designing exterior spaces and paving and site work contractors to maintain these connections manually risk inconsistencies that surface as coordination issues downstream.

How CSI Dynamic Standards Helps with Division 32 in Design Development

CSI Dynamic Standards includes Division 32 as part of a connected, edition-aware classification system—licensed through The Construction Standard. Built for real project work from concept to closeout and beyond, it provides always-current Division 32 section numbers and titles, governed cross-references to UniFormat and OmniClass, and edition tracking that prevents design development deliverables from referencing obsolete classification data. For teams working through the design development phase, this means Division 32 references in every deliverable stay accurate and consistent with the rest of the project manual.
