Whether a construction project is carried out using BIM or traditional methods, quality management is a crucial aspect of project execution. In the context of BIM, however, there is a greater reliance on the data that other project participants must provide. If the data received is incomplete, inconsistent, or simply inaccurate, this can significantly impair the further course of the project, especially during commissioning or the ongoing operation of a building.
Model-checking software, such as Solibri Model Checker, can verify the object properties of a submitted IFC model for compliance with the original information requirements. If information is missing from the submitted model, this is indicated by a visual error message. The check is performed using predefined rules (Solibri rules).
A model check must be performed for each of three key data transfers:
before exporting a model to the project team;
upon receipt of a model from another discipline;
when coordinating discipline-specific models.
Of course, the use of tools such as a model checker is both sensible and necessary for verifying the content. However, its use is generally limited to the specialists on the team.
Regular users—and thus those responsible for the data—must be trained in the operation of a model checker and how to handle the verification results.

Based on project experience with customers using BIM, eTASK has established Solibri rules to check IFC models in advance before they are imported into the eTASK portal. We make these Solibri rules available to all our customers free of charge.
Tip: The rules can be downloaded as a .cset file here.
A description of the individual rules can be found here: 📄 Beschreibung der Solibriregeln IC2654

When using Solibri and checking an IFC model, questions may arise that must be clarified by the respective responsible parties directly with the manufacturer or supplier of the model checker software.
Note: Distinction from the eTASK Model Requirements (EMA): The EMAs are purely technical minimum requirements of the eTASK software that are necessary to run BIM. Some EMAs are also included in the eTASK Solibri rules, but they do not cover all EMAs. The Solibri rules offer an optional way to perform a quality check in advance before the IFC model is imported into eTASK. Modelers can thus perform their own preliminary checks if they are using Solibri. Furthermore, the Solibri rules can be customized for specific projects, such as geometry checks. The EMAs do not offer geometry checks. The eTASK Solibri rules can be used as a basis for creating project-specific validation rules.
