Research shows that a COBie database from BIM helps facility managers respond to work orders 8.7% faster, saving 11.6 minutes per order. By keeping building data well-organised and easy to access, COBie improves efficiency, reduces delays, and makes facility management smoother.
It ensures data stays accurate and useful from design and construction to daily operations. In this article, you’ll learn about COBie, how it works, its role in asset management, and practical ways to overcome common challenges.
What is COBie?
COBie, also known as Construction Operations Building Information Exchange, is a standardised format for organising and sharing important building information during construction. It focuses on collecting and transferring details about building assets, such as equipment, materials, and systems, that are critical for maintenance and operations after construction.
COBie makes it easy to share accurate and consistent building information throughout its life. It helps project teams and stakeholders ensure smooth collaboration and easy data sharing. For facility managers, it provides reliable information to manage buildings better and reduce running costs.
By understanding how COBie simplifies data sharing and management, we can appreciate its role in modern construction and facility operations. To better understand COBie’s impact today, it’s helpful to explore its origins and the journey that shaped its development.
History of COBie
COBie was developed in the mid-2000s by the USACE (United States Army Corps of Engineers) and the NIBS (National Institute of Building Sciences). It was designed to fix problems in facility management caused by unorganised and inconsistent data sharing during construction.
Over time, COBie became part of the larger Building Information Modelling (BIM) system and is now popularly used in the architecture, engineering, and construction (AEC) industry to simplify facility management throughout a building’s life.
As COBie has become an important tool in the AEC industry, its connection to BIM has grown significantly. Understanding how COBie works with BIM helps show how it simplifies building data and improves project workflows.
How Does COBie Relate to BIM?
COBie and BIM work hand in hand, with COBie serving as a key method for organising data within the BIM process.
BIM is a virtual building representation that integrates both its design and functional aspects. It helps with decision-making at every stage of a building’s lifecycle—from design and construction to operation. BIM combines various types of data, such as architectural, structural, mechanical, electrical, and plumbing information, into a single, shared 3D model.
COBie, on the other hand, is a standardised way of organising and managing the data created during a BIM project. It focuses specifically on the information needed to operate and maintain the building after construction.
BIM manages vast amounts of data, while COBie simplifies this information into a structured, spreadsheet-like format that’s easy for facility managers to understand and use. COBie simplifies the organisation of essential data but represents just one piece of the broader BIM framework.
Comparing COBie with other standards like IFC helps clarify how each of them serves a unique purpose in data sharing and project collaboration.
What is the Difference Between IFC and COBie?
In BIM, smooth data sharing is key to effective collaboration among project teams. Two widely used standards that support this are IFC and COBie. While both are designed to improve data management and sharing, they serve different purposes.
Knowing the difference between IFC and COBie helps architects, engineers, contractors, and facility managers decide which one is best for their project. Below are the key differences between IFC and COBie:
| Aspects | IFC (Industry Foundation Classes) | COBie (Construction Operations Building Information Exchange) |
| Purpose | A complete data model for the exchange of information across the lifecycle of a building (design, construction, operation). | Focused on the documentation and handover of asset data during construction, primarily used for facilities management. |
| Scope | Broad, covering architecture, structure, mechanical, electrical, plumbing (MEP), and more. | Narrow, focusing primarily on asset data (equipment, components, spaces) needed for operations and maintenance. |
| Data Focus | Contains detailed geometric, spatial, and non-spatial data. | Emphasises non-geometric data, such as equipment specifications, maintenance schedules, and warranty information. |
| Primary Use | Used throughout the entire building lifecycle – design, construction, and operation. | Used primarily during the handover phase for operations and facilities management. |
| Standardisation | An open, neutral standard governed by buildingSMART International. | Standardised by the U.S. government, focusing on facilities management and operations. |
| Data Format | Uses a complex data model that includes geometry, relationships, and data about building components. | Uses a simplified spreadsheet format (usually Excel) for easy data entry and management. |
| Level of Detail | Highly detailed, including geometry, relationships, and material data. | Less detailed, focusing on essential asset data like manufacturer, model, serial numbers, etc. |
| Adoption | Widely adopted in BIM for design and construction. | Primarily used by facility managers, building owners, and operations teams post-construction. |
| Integration with BIM | Fully integrated with BIM, including 3D models and detailed construction data. | Can be extracted from BIM models but does not include geometry or spatial data. |
| Data Requirements | Requires data from all building disciplines (architectural, structural, MEP, etc.). | Requires specific operational data about systems, components, and spaces for operations. |
| File Format | Often stored in a proprietary IFC format (.ifc), compatible with various BIM software. | Typically stored in spreadsheets (.xls or .csv) for easy exchange. |
Understanding how COBie differs from other standards like IFC highlights its unique advantages. These benefits are crucial for improving project efficiency and teamwork.

Understanding COBie’s role in asset management shows why its structure is so effective. Its effectiveness comes from a few key principles that guide how COBie organises and manages information.
Basic Principles of COBie
COBie is based on simple principles that help organise, share, and use building information efficiently. These principles ensure that data is collected, structured, and shared consistently.
By understanding these principles, teams can make the most of COBie to improve project workflows, avoid mistakes, and manage building assets effectively in the long run.
Below are the key principles of COBie, including its data structure, format, and classification methods:
1. Data Model
COBie is based on the buildingSMART International data model and works as an IFC MVD (Model View Definition), ensuring compatibility with various software, systems, and workflows. Its open and standardised format allows smooth data sharing, making it an essential part of BIM processes.
COBie is organised into multiple worksheets, which are grouped into three main sections:
Design Zone
The Design Zone organises important information about assets, spaces, and systems during the planning and design phase. It ensures that data is properly organised, making it easy to transfer and use for efficient facility management in the future. Below are the key elements of the design zone:
| Category | Key Details |
| Component | Tracks equipment by using data from specifiers, designers, suppliers, and contractors, including details like serial numbers, asset IDs, and installation dates. |
| Type | Groups properties by type, covering owner, manufacturer, model, material, warranty, maintenance schedules, replacement costs, and service history for lifecycle management. |
| Space | Includes rooms, walkways, or parking lots housing equipment, ensuring maintenance access while supporting space and tenant management. |
| Zone | Groups spaces with a shared purpose and functionality, mainly post-handover. |
| Facility | Represents buildings or infrastructure sections defined by EIR (Employer’s Information Requirements), BEP (BIM Execution Plan), or project contracts, with each spreadsheet corresponding to a single facility. |
| Floor | Associates spaces with specific floors, organising data hierarchically for clarity. |
| Systems | Classifies equipment by function (e.g., HVAC), simplifying operations and maintenance tasks regardless of zones or spaces. |
Build Zone
The Build Zone records the resources, tasks, and spare parts needed for construction and facility management. It ensures all required materials, tools, and responsibilities are clearly documented for smooth operations and maintenance. Below are the key elements of the build zone:
| Category | Key Details |
| Job | Documents task assignments for facility management, defining roles and responsibilities clearly. |
| Resource | List materials, tools, and training resources required for efficient facility operations. |
| Spare | Tracks replaceable components for assets, ensuring efficient maintenance and repair processes. |
Common Zone
The Common Zone collects key information to help project stakeholders work together and stay organised. It includes contact details, linked documents, and extra data to make information easier to access and use. Below are the key elements of the common zone:
| Category | Key Details |
| Contact | Stores contact info, company details, and organisational roles, ensuring stakeholder coordination. |
| Document | Links external files (e.g., manuals, warranties) to related data for easy access to supplementary information. |
| Attribute | Optional worksheet storing detailed property data for components or types based on project-specific needs and workflows. |
2. Format
COBie offers different delivery formats and allows project teams to choose the best for their needs based on project size, complexity, and preferences. The most common delivery formats are:
- IFC File: The IFC file format is the most common way to share BIM data. BIM tools can generate COBie-ready IFC files or link them to manufacturer BIM objects. This format works best for large projects because of its compatibility and accessibility.
- Spreadsheet (COBie Sheets): COBie data is organised in rows and columns across worksheets. This format is easy to use but requires careful and consistent formatting to avoid errors. However, it’s not ideal for large or complex projects due to limitations in handling large amounts of data.
- Database: A database centralises COBie data that simplifies validation, tracks, and exports while providing better control over large datasets. This approach fully increases COBie’s potential but requires significant effort for setup, configuration, and ongoing management.
3. Classification
COBie offers flexibility in selecting classification systems and allows project owners to choose one that suits their region or specific needs. Some common examples include:
- UniClass: Popular in the United Kingdom.
- OmniClass: Common in the United States.
- Norwegian Standard 3451: Specific to Norway.
However, no matter which system is chosen, it’s important to ensure it aligns with the COBie format being used—whether it’s IFC files, spreadsheets, or databases. Remember that small variations in how the system is applied might occur depending on the format.
Following COBie principles helps ensure that information flows smoothly from design to operation. While these principles create a solid framework for efficient data management, implementing them can come with its own set of challenges.
Challenges and Solutions in COBie Implementation
The COBie standard has changed how facility management teams receive and use data from building projects. However, its implementation can come with challenges that might reduce its effectiveness.
By understanding these challenges and addressing them with clear strategies and the right tools, the COBie process can become much smoother and more efficient.
Below are some common challenges and practical solutions to overcome them:
| Challenges | Solutions |
