We know that a BIM project cannot rely solely on a great 3D model. This 3D model needs to be enriched by data—but not any data!
Data embedded in a model must be relevant, fulfill a specific requirement, and aim for a specific purpose. It should be well-organized, accessible, and easy to extract.
Data is everywhere in Archicad. Fundamentally, it is a database containing all the information embedded in your project elements. The quality of this data is vital for ensuring consistency, reducing risks, and increasing productivity.
As a BIM Coordinator, data production was at the core of my daily tasks. I had to understand what type of data was required for the projects I was responsible for, at which stage of the project the data was required, and if there were any standards to be followed. Moreover, efficient data production meant I could run efficient quality assurance checks.

What type of data do we have in a BIM Project?
Data can be categorized into two main types: geometric and metadata.
- Geometric is visual data – physical information that can be seen.
- Metadata is largely non-visual data (although it can be visualized using Graphic Overrides). Here we can mention Classification Systems, Element ID, Structural Function, Position, Renovation Status, Properties, Layer
An effective data management strategy is the key to unlocking the full potential of your projects. It will support automated data processes, streamline workflows, and save time.
A practice working with BIM-enabled projects should aim for a structured data strategy. The BIM Manager should be responsible for understanding the typical project requirements and for predicting possible data strategies that will help a new project start-up.
When talking about data strategy, what are the key points to consider?
-
Know the purpose of your model
Consider various purposes such as analysis, cost management, design review, 3D coordination, documentation, and asset management. Knowing the goals makes it easier to decide on the data type required and how to manage it effectively.
-
Understand the project deliverables
ISO 19650 introduces the concept of 'Level of Information Need' (LOIN), which determines the quality, quantity, and granularity of information required for each deliverable.
Appointment documents, such as Exchange Information Requirements (EIR), establish LOIN by element and project stage.
-
Know your practice’s internal requirements
Define which data is necessary for the effective development of a project, regardless of the client’s requirement.
There may be situations where the appointment does not specify data requirements, and the client does not intend to use the model during or after construction.
However, even in such cases, some basic data is essential to ensure smooth collaboration with other consultants and efficient 3D coordination.

Understanding the different data types and their systems is crucial for effective data management. Recognizing the importance of each data requirement and how it impacts data production is essential for producing a reliable data strategy that will lead to an efficient model.
