IFC Checker and BIM Validation

BIM validation is the process of validating the accuracy and completeness of the data in a BIM model. Specifically, with BIM validation, the model is verified against a set of predetermined criteria to ensure that it meets all the necessary requirements.

This process can be carried out manually or through the use of software.

Manual data validation involves reviewing the data within the model and comparing it with reference documents such as drawings, reports and plans.

Automatic data validation can be performed using software that verifies the model against a set of rules or criteria. In both cases, the goal is to ensure that the model data is correct and complete.

Data validation is an important part of any BIM project, as it helps to ensure that the model can be used to accurately represent the construction project.

It contains information of various types (geometric data, properties, relationships with other objects).

The BIM data validation process is important to ensure that the BIM model is of high quality and meets the user's needs. Through the BIM data validation process it is possible to:

• ensure that the model data is accurate and up-to-date and meets the project's requirements;
• identify errors, omissions and discrepancies in the data;
• ensure that the project can be completed on time and on budget;
• increase the efficiency of the BIM modeling process.

The purpose of BIM validation is to ensure that all the information used in the design and construction phases of a project is correct. It is therefore clear that BIM validation is a valuable tool for anyone who wants to ensure that their building or construction project runs smoothly from start to finish.

Designers, BIM Specialists, BIM Coordinators and BIM Managers who need to assign, verify or eliminate certain characteristics of the BIM model or the contracting authority operators (public bodies/consultants) in charge of controlling the delivered projects may be involved in the BIM validation processes.

usBIM.checker checks all entity-related properties from 'smart' object selections.

usBIM.checker is very useful for the verification phase of an IFC model, in summary it can:

• verify the existence of properties of objects;
• view and check property values;
• verify the correctness of values;
• generate and export property control templates;
• insert, modify and delete properties;
• generate a consistency report between the properties and the values contained in the IFC file.

With usBIM.checker you can define the following conditions:

• At least - enables the IFC model to be granted 'at least' the properties that are listed in the spaces provided;
• Only - allows you to determine "only" those properties that must be present in the IFC model
• Verification - allows you to check whether the properties that have been identified in the spaces provided are present in the IFC model;
• Delete - this function gives the possibility to delete the properties present in the model (in this case there is no possibility to use a selection filter as in the previous cases).

usBIM.checker is an IFC file checker designed to solve the problems of checking, inserting and deleting properties.

It can greatly simplify all those operations that would be much more cumbersome and complex with a typical BIM authoring.

Yes, with usBIM.checker you can export your template for use in another project (the template is separate from the model).

With these templates, you can take advantage of the same selection and control filters on several templates and optimise the verification operations.

You can easily create a template by selecting appropriate filters (object selection criteria), identifying attributes, PsetNames, properties, etc., and specifying the properties to be inserted or checked (checks to be made on properties).
