IFC-SG Resource Toolkit
Welcome to the IFC-SG Resource Toolkit.
This resource toolkit comprises the recommended steps and materials to prepare an IFC-SG model for submission via CORENET X.
Step 1
Introduction to IFC-SG, key data structures and mapping
Step 2
Latest Industry Mapping Excel Files
The Industry Mapping excel file will help you to:
- Better understand the IFC-SG requirements for different agencies
- Map the IFC Key Data Structures for each building component
- Understand other details of each building component, such as the associated agencies, disciplines, parameters

Further info on the Industry Mapping Excel
If IFC-SG dimension parameters such as "Length", "Breadth" match the native BIM objects' parameters, there is no need to manually add the dimension values in the project. These dimensions will be automatically filled in for the parameters via the IFC-SG configuration files provided in this IFC-SG Resource Toolkit.
The
Column Description table below describes each column header in the Industry Mapping Excel and is colour coded for ease of reference. You may also refer to the
Pivot tab in the excel file in which the IFC representations have been grouped by entities or components.

IFC4 Entities |
IFC Entity [Key data structure (i)]
An Entity is an object defined in the IFC data model.
It can be used to define a physical element or a conceptual idea (eg. space) |
|
| I |
IFC Sub Types |
IFC Sub Type [Key data structure (ii)]
Provides next level of information to further describe the Entity. These sub-types are a combination of Predefined and User-Defined Types. |
- Sub Types without prefix (*) = Predefined Type
- Sub Types with prefix (*) =User-Defined [Key data structure (iv)]
|
| J |
Property Set |
Property set [Key data structure (iii)]
Set/Group of Properties that describes the function or feature of the Entity |
- Property set without prefix "SG" are buildingSMART predefined property sets e.g. Pset_WallCommon
- Property set with prefix "SGPset" [Key data structure (v)] are local requirements. e.g. SGPset_Wall
|
| K |
Property Name |
Property [Key data structure (iii)]for the Component |
|
| L |
Property Type |
IFC Data Type for the property |
e.g. Boolean = True/False, Label = Text |
| M |
Property Unit |
Indication if property value is of certain units |
e.g. mm |
| N |
IFC4 Material Set |
Indicate if object needs to include material |
User to note that Materials information to be input via the native parameter. Example of Wall material below:

After you have a better understanding of the agencies' requirements in IFC-SG, you may proceed to Step 3 to learn how to apply the IFC-SG information for each BIM authoring tool.
Step 3
Step-by-step resources on how to apply the requirements in the Industry Mapping Excel into your respective BIM software and how to export to IFC.
Notes:
- These resources in Step 3 are optional templates created to help users embed and export IFC-SG regulatory data requirements as indicated in Step 2. Firms may use your own in-house templates instead, as long as your CORENET X submission models contain the relevant data in Step 2.

IFC-SG Classifications have been integrated into the AC 2.0 classification. You can classify objects in the project, the associated properties will be shown.
The AC template and classification will handle the Sub types upon export. You can check the IFC properties under "Classification and Properties" to ensure the entity and subtypes are correct. |

Important - You must check your IFC files in an external IFC viewer after exporting from Revit. If you are unable to federate the IFC versions of your Revit linked files together, pls refer to this webpage immediately for troubleshooting

(Note that this list is not exhaustive)
*System Entities include IfcBuildingSystem (ARC), IfcDistributionSystem (MEP)
IFC Binder
** To view multiple IFC files in FOC viewers that are unable to federate IFC models, the "1IFC" app, which is also FOC, could be used. This openBIM application has been specially created by Graphisoft, is based on C# and is able to bind multiple IFC files.

FAQ
Q: Why do the configuration files contain more parameters than what was stated in the Excel file?
A: The information stated in the Industry Mapping (Excel) denotes the scope of the current phase of CORENET X development.
Q: Dimensions such as Length, Width, Depth, Height are available as part of the BIM object, do I have to create them as custom parameters and input the values manually?
A: Please note that most of the dimensions will automatically be exported via the software configuration when exporting to IFC. Please ensure that the property name matches the configuration for automatic extraction. Users should refer to the respective BIM authoring tool's How-To Guide for detailed steps on how to use the configuration files.
Q: My company uses "Floor" for modelling ramps. It this acceptable for the requirements for Ramps?
A: The BIM representation columns are mainly for reference and are not to be taken as strict requirements.
Users are free to use any tools or category for modelling as long as the output in IFC follows the mapping. For example, if a user decides to use Floor instead of Ramps, the users will need to perform the IFC overriding feature that is available for the respective BIM authoring tool. Please refer to the respective BIM authoring tool’s How-to Guide for the detailed steps.
