In this issue, we continue exploring the standard COBie format for BIM in facility maintenance management, focusing on its specific applications. The COBie electronic spreadsheet does not contain a complete BIM model; instead, it includes only the essential information needed for export and data exchange. For example, consider a single pump equipment model located on the basement floor (as shown in Figure 4). Using a spreadsheet as the primary data exchange format, we will explain how COBie functions in this context.
Assuming the user creates a BIM model with Autodesk Revit software and has assigned property data such as floors, spaces, and zones to equipment locations within the model, they can then use the Autodesk Revit 2014 COBie tool. This tool allows users to export either a single component or the entire BIM model into a COBie spreadsheet for use in later lifecycle stages. For instance, Figure 5 displays the Component worksheet, which identifies the category of each device and its associated space. Figure 6 presents the System worksheet, outlining the building’s various service systems along with their included components and equipment. Figure 7 shows the Attribute worksheet, which converts device attribute data defined in the BIM software into a tabular format. Users can directly access COBie electronic spreadsheets to retrieve necessary data or import them into compatible software that supports COBie standards.
Currently, software supporting COBie technology can be broadly categorized into three groups: BIM modeling software, construction project management software, and facility maintenance management software.
BIM modeling software enables the creation of BIM models and the definition of related object properties, including spatial information required for subsequent facility management system integration. Examples of such software include Autodesk Revit, Bentley AECOsim, Tekla, and Graphisoft ArchiCAD.
Construction management software supporting COBie standards can import electronic spreadsheets or IFC files exported from BIM modeling software to carry out project management tasks. During the construction phase, relevant BIM model data and project information can be continuously updated, added, or deleted. Software solutions in this category include 4Projects, Constructivity, and Project Blueprint.
The COBie information exchange format facilitates seamless communication of data from design and construction phases through project delivery, covering the entire building lifecycle. Ultimately, this data can be imported into facility maintenance management systems for ongoing operations and maintenance. Examples of facility management software that support COBie standards include ARCHIVE, EcoDomus FM, FM:Systems, Onuma, and others.
