CADBIMmodelleer

CADBIMmodelleer is the practice of creating digital representations of buildings by combining computer-aided design (CAD) drafting with building information modeling (BIM) methodologies. The aim is to produce one information-rich model that supports design, analysis, construction, and facilities management throughout a project’s life cycle.

In CADBIMmodelleer, CAD traditionally focuses on geometric representation, while BIM adds metadata and behavior to building elements. This means not only the shape and position of walls, doors, and components, but also data such as materials, costs, performance characteristics, and relationships between elements. BIM enables collaboration through a shared model and centralized data, reducing duplication and miscommunication among architects, engineers, contractors, and owners.

Software tools commonly used in CADBIMmodelleer include AutoCAD, Revit, ArchiCAD, and various BIM-focused platforms from Bentley Systems or similar vendors. Interoperability is often facilitated by open standards such as the Industry Foundation Classes (IFC). International guidance like ISO 19650 provides a framework for information management, while levels of development (LOD) describe the increasing detail and reliability of the model as projects progress.

Typical workflows cover design development, coordination and clash detection, construction documentation, and digital handover to operations. In advanced stages, the model supports 4D planning (time) and 5D cost estimation, as well as facilities management after handover.

Benefits of CADBIMmodelleer include improved coordination, reduced rework, better decision making, and more accurate quantity takeoffs. Challenges include data governance, software fragmentation, training needs, and ensuring data quality and consistency across disciplines.
