MasterFormat Division 32 – Exterior Improvements in the Schematic Design 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 schematic design phase intent.

Division 32 Activities During Schematic Design

Schematic design is where building systems take shape and early cost decisions are made. UniFormat provides the elemental framework for SD-phase cost models, comparative analysis, and scope documentation. CSI Dynamic Standards uses governed crosswalks to reveal the right MasterFormat sections as systems firm up—so scope decisions carry forward without manual remapping. For Division 32 specifically, the schematic design phase involves focused work on exterior improvements scope, products, and execution requirements. Use governed crosswalks from UniFormat elements to begin identifying MasterFormat specification sections. Refine the TOC as building systems are defined.

Key activities for Division 32 during schematic design include:

• Map UniFormat elements to MasterFormat sections as systems firm up — as it relates to exterior improvements sections and the products, methods, and quality standards they define
• Refine specification TOC based on evolving design scope — as it relates to exterior improvements sections and the products, methods, and quality standards they define
• Tag early BIM model elements with OmniClass classifications — 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 When teams reference outdated or incorrect section numbers during schematic design, the errors propagate into every subsequent phase.

Division 32 Sections Referenced in Schematic Design

The following Division 32 sections are commonly referenced during schematic design 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 schematic design, these section references appear in updated specification toc and must be consistent with the project manual.

Schematic Design Deliverables That Reference Division 32

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

• Updated specification TOC

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

Common Issues with Division 32 During Schematic Design

• SD cost models that can't be compared to DD or CD estimates — When this occurs with Division 32 references during schematic design, the result is rework, coordination failures, or documentation that contradicts the project manual.
• Specification sections identified too late in the process — When this occurs with Division 32 references during schematic design, the result is rework, coordination failures, or documentation that contradicts the project manual.
• BIM model elements with no classification structure — When this occurs with Division 32 references during schematic design, 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 schematic design, the higher the cost of classification errors.

Cross-Standard Connections for Division 32 in Schematic Design

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 schematic design 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 Schematic Design

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 schematic design deliverables from referencing obsolete classification data. For teams working through the schematic design phase, this means Division 32 references in every deliverable stay accurate and consistent with the rest of the project manual.
