In all modeling guides, there is a tab titled "Revit BOA" in the instructions section. This section is a unique feature of BIMpedia. It provides specific instructions related to the BIM Office Administration Modeling Standard, or BOA for short.
Every Revit user knows that when using this software, there are many ways to achieve the same result in almost all workflows. The BOA Standard supplements the general guidelines for working with Revit with specific requirements that relate to a concrete work standard.
This standard was developed over many years by the operators of BIMpedia in collaboration with leading integrated design firms such as ATP Architects and Engineers. More than 500 integrated design firms throughout the German-speaking world are already working according to this standard!
To work efficiently according to this BOA standard, you will need the template and the object catalog for Revit. These are available to BIMpedia customers starting with the Premium package. Here you will find all the information about our template and the associated object catalog.
A distinctive feature of the BOA methodology, which is repeatedly referenced in the modeling guidelines for all disciplines, is the handling of Revit layers: Unlike the common practice of using layers as floor markers (without further differentiation), the BOA standard always uses four layers per floor:
FBOK - Floor Top Edge
RDOK - Upper edge of the raw ceiling (used as a floor level marker)
RDUK - Lower Edges of Raw Slabs
ADUK - Lower edge of the slope cover
The reason for this approach is that many objects across different disciplines often have direct links to these logical reference levels, making it easier to modify them centrally—for example, when floor heights are changed.
In addition, this is intended to minimize the error-prone use of "offsets."
In addition to the actual BIM modeling authoring tools, such as Revit or ArchiCAD, many guides frequently mention the use of certain additional tools. The BIM Office Administration Standard is based on the proven integration of many different tools—which are described in this article.
It is therefore possible that some of the workflows described can only be implemented exactly as described if the necessary software is available in-house. Nevertheless, all recommendations and instructions in the modeling guides are generally designed in such a way that they provide added value in BIM data generation and management even without the use of specialized tools.
