Objective
Qualitative studies point out that the current quality assurance of building models is both time consuming and defective. This study evaluates the integrated validation function in IfcDoc in relation to efficiency of the validation process.

Method
The report follows the data modeling process to define a subset in the Ifc-schema according to a set of property data (LOD-dk levels), which are stated in “bygningsdelsspecifikationer” developed by DiKon and BIM7aa. This subset is called a Model View Definition (MVD). The MVD development forms the basis for an assessment of the validation function in IfcDoc.

Result
MVD development based on the information levels streamlines the validation process through the use of a dedicated function in IfcDoc. One of the benefits of the MVD approach enables exploitation of object-oriented data modeling principles including the generalization. It counteracts repetition and duplication. However, the core objective of the MVD approach is not validation at attribute level.

Conclusion
The developed solution has potentials to streamlining the cumbersome validations process. However, the problem is not addressed by the root. The MVD approach should instead be used as a neutral requirement specification form based on the total information needs of some actors. And not used to validate information levels at an attribute level, since the attributes are somewhat different and are located in different locations depending on the software.
