Division 31: Earthwork for Owners & Facility Managers

Owners & Facility Managers engage with MasterFormat Division 31 – Earthwork throughout the project lifecycle. Division 31 covers site earthwork—clearing, grading, excavation, fill, soil stabilization, and erosion control that prepare the ground for construction. For owners & facility managers, Division 31 is where organizes owner project requirements, design guidelines, master specs, o&m manuals, and procurement catalogs by standardized divisions and sections..

How Owners & Facility Managers Use Division 31 – Earthwork

Organizes owner project requirements, design guidelines, master specs, O&M manuals, and procurement catalogs by standardized divisions and sections. Division 31 is one of the divisions that owners & facility managers encounter most frequently in practice. The sections within Division 31 define the products, execution methods, and quality standards that owners & facility managers must reference, review, or author.

Key sections within Division 31 include: - 31 10 00 – Site Clearing - 31 20 00 – Earth Moving - 31 23 00 – Excavation and Fill - 31 25 00 – Erosion and Sedimentation Controls - 31 30 00 – Earthwork Methods

These sections shape how owners & facility managers publish owner project requirements, design guidelines, and master specs using masterformat numbers/titles. When section numbers are outdated or inconsistent, the downstream impact on owners & facility managers is immediate: asset data that doesn't transfer cleanly to FM systems.

Division 31 in the Owners & Facility Managers Workflow

Organizations using CSI standards in operations, assets, project requirements, RFPs, contracts, BIM Execution Plans, CMMS/CAFM/EAM systems, and capital planning. Within this scope, Division 31 plays a specific role:

1. Documentation — Owners & Facility Managers publish owner project requirements, design guidelines, and master specs using masterformat numbers/titles. Division 31 sections must be correctly numbered and titled in every document that references them.
2. Coordination — Division 31 scope intersects with other divisions on every project. Owners & Facility Managers need consistent classification to coordinate earthwork work with adjacent trades and disciplines.
3. Quality — maintain capital planning libraries in uniformat and convert them to masterformat packages for procurement.

Pain Points Owners & Facility Managers Face with Division 31

• Asset data that doesn't transfer cleanly to FM systems — When Division 31 section references are affected by asset data that doesn't transfer cleanly to FM systems, the result is rework, RFIs, or coordination failures that owners & facility managers must resolve.
• Inconsistent handover documentation — When Division 31 section references are affected by inconsistent handover documentation, the result is rework, RFIs, or coordination failures that owners & facility managers must resolve.
• RFP ambiguity around classification requirements — When Division 31 section references are affected by RFP ambiguity around classification requirements, the result is rework, RFIs, or coordination failures that owners & facility managers must resolve.

These issues compound across projects. A single incorrect Division 31 section number in a team's template can propagate across every project that uses that template.

Division 31 Cross-References for Owners & Facility Managers

UniFormat: Division 31 maps to UniFormat G (Sitework)—the site preparation work that precedes building construction.

OmniClass: OmniClass Table 22 (Work Results) includes earthwork results; Table 13 (Spaces by Function) covers site spaces.

Understanding these connections helps owners & facility managers maintain consistency when Division 31 work touches UniFormat elements or OmniClass classifications in their deliverables.

Why Owners & Facility Managers Need Current Division 31 Data

CSI Dynamic Standards includes Division 31 as part of a connected, edition-aware system—licensed through The Construction Standard. For owners & facility managers, this means always-current section numbers and titles for Division 31, governed cross-references to UniFormat and OmniClass, and edition tracking that prevents referencing obsolete classifications in owners & facility managers deliverables.
