Rule ID: SUK/1007/v1.0
This article describes the Fire Stopping Dimension Rule that has been developed by Solibri UK Ltd as part of the BIM Coordination + Library.
The rule is available for Solibri Office 9.13.1 or later via a Solibri Extension, which can be downloaded from the Solibri Solution Center.
The article covers the following topics:
Important
The parameters in this rule must be defined by the user to give meaningful results.
Important
This rule requires connection to an external spreadsheet and the Fire Seal Dimension sheet. A copy of this default template for all Fire Stopping rules FireStoppingRequirements.xlsx can be downloaded at the end of the Introduction article or through the description in the checking view for the highlighted rule.
Tip
To learn more about the Fire Stopping Solution, please see Introduction to Fire Stopping of Service Penetration Checks.
This rule is used to check both the minimum and maximum sizes of each fire seal.

The rule first checks that all components filtered as Fire Seals have their fire seal types classified by the Fire Seal Classification. The rule then finds all fire seal components on compartmentation walls through their corresponding filters. Those fire seals are checked to ensure that their minimum and maximum width and height dimensions are correct. A Fire Seal Dimension sheet within a spreadsheet (.xlsx) defines these requirements based on the fire seal type. Any types from the Fire Seal Classification that are unspecified within requirements file are also returned as issues to be addressed.
Important
Although only the services and fire seals filters of these rules require users to set up classifications, it is good practice to also use classifications for the compartmentation. The benefits are as follows:
-
Helps to structure the model geometry allowing easy identification and visualization in the classification providing a clear indication of what will be checked
-
Where present, Services and Fire Penetration Seals will require classification values to interact with the FireStoppingRequirements.xlsx
Tip
The screenshots shown here have been taken from the FireStoppingRequirement_EXAMPLE.xlsx spreadsheet which is available for download from the end of the Introduction article.

In the Parameters View, you can define:
-
Walls filter: Defines the compartmentation walls to have fire seal dimensions requirements checked.
-
Fire Seals filter: Defines the fire seal components to have their dimensions checked.
-
Fire Seals Classification: Defines the name of the Classification for Fire Seal Types that will have their requirements checked. The Fire Seal Dimension sheet in the Requirements file references the classifications names from this Fire Seals Classification to define the corresponding dimension requirements of the fire seal types.
Tip
Copy and paste the Classification name directly from the Settings tab of the Classification used to define your services to ensure there are no errors
-
Fire Seal ID Property Reference: Specifies the property of the fire seal to categorize results by in the results view.
-
Requirements File Path: Defines the full file path to the spreadsheet (.xlsx) that contains the Fire Seal Dimension sheet used to define required distances between fire seal types.
Tip
Requirements File Path – Copy the location from the path in Windows Explorer or from a macOS command window to ensure there are no errors
Fire Seal Dimension Sheet parameters

-
Fire Seal Types (separated by semicolons, can contain wildcards): This cell contains the fire seal type name(s) to match from the Fire Seals classification to define their dimensions requirements. If multiple names are listed, those fire seal type names must be separated by semicolons (;). The use of the Asterisks (*) and Question Mark (?) and double hyphen (--) wildcard characters can be used to match names as below...
-
* Matches 0 or more characters
-
? Matches exactly 1 character
-
-- Matches anything but what comes after the double dash
Note
The File Seal Types entered in column A of either the Wall or Floor Proximity sheets will need to be classified within Solibri. The classification name should relate to the type of Fire Seal not each individual instance as this is covered by the Fire Seal ID Property Reference value within the rule parameters. As the project progresses these may go from generic to specific manufacture ID’s for their approved test conditions.
-
-
Minimum width (mm): This cell contains the minimum width in millimeters for the defined fire seal types. A value is required in the cell and must be a positive numerical value.
-
Maximum width (mm): This cell contains the maximum width in millimeters for the defined fire seal types. A value is required in the cell and must be a positive numerical value.
-
Minimum height (mm): This cell contains the minimum height in millimeters for the defined fire seal types. A value is required in the cell and must be a positive numerical value.
-
Maximum height (mm): This cell contains the maximum height in millimeters for the defined fire seal types. A value is required in the cell and must be a positive numerical value.
-
Issue Category (empty for default): This cell contains optional text to be included in the result titles of dimension violations found for the defined fire seal types.
The rule results fall into two categories:
-
Fire seal ID
The rule creates categories using the values from the property defined in the Fire Seal ID Property Reference parameter. These categories group fire seal dimension violations by their specified Fire Seal ID:
-
Critical (
) severity results are listed for minimum/maximum width / height dimension violations.
-
Moderate (
) severity results are listed for fire seals on compartmentation walls to be checked and classified with fire seal types in the Fire Seal classification but are missing a corresponding row for those types in the Fire Seal Dimensions sheet of the requirements file.
-
-
Unclassified Fire Seals - this category has a single low (
) severity result listing all components filtered by the Fire Seals filter parameter table to be checked but are missing their fire seal type classification in the Fire Seals classification.
Severity
In addition, you can specify the severity classes according to your preferences and priorities in the Severity Parameters dialog. For example, you can filter specific fire seal components to have critical or low severity results based on their Fire Seal type.
Controlling the Issue Title
Issue result titles are created based on the following logic:
![]() |
![]() |
![]() |
This means two parts of the issue title can be controlled by the user.
