COBie is a common deliverable for BIM projects worldwide. It involves assigning parameters to elements that is then populated with data and used in facilities management. This typically happens from the end of the design and especially during construction and commissioning.

When exporting to COBie there are only so many parameters that can be assigned to the standard COBie schema. Is it possible to include other parameters?

For example, take a Window. The team would like to include various materials for the window. Now, these are standard for Revit. As can be seen in the image below, there are type parameters for the exterior frame, the interior frame, the pane, and the sash.

Yet, when exporting with Cobie, there is only one parameter for the output of the material. While one can concatenate one’s own parameters together to make up the value of a COBie parameter, there is no way to create one’s own COBie parameters.

There is the option to export additional attributes out to the Cobie Spreadsheet and if enough attention is paid to the export format, one can get all the required information from it.

Below is shown the information that flows from the export. As can be seen, the Type properties are visible, and the Type Name is given by the RowName Column.
