BIM (Building Information Modeling) depends heavily on the level of detail incorporated within the model. The more detailed the model, the easier and more accurate it becomes to extract, combine, and process information, resulting in clearer and more precise visualizations. However, increasing detail also means adding more components, which significantly increases the workload for maintaining related data, such as supplier information. As a result, this often slows down the modeling process. In this article, we explore several key factors that influence the speed of BIM modeling.
1. Creation of New Families
Modern architectural designs frequently introduce new products and materials. Components like doors, windows, lighting fixtures, and gate valves often change, and existing BIM families may not cover these new elements. This requires modelers to continuously create and update BIM families. The closer these families need to reflect actual products, the longer the development process becomes, which can significantly impact the overall modeling timeline.
2. Modeling of Irregular Structures
Irregular structures—such as uniquely shaped tubes, columns, and beams—are typically created using volume-based modeling techniques. BIM software uses operations like extrusion, rotation, and cutting to form these complex shapes. Producing such components demands substantial computing time and resources and often requires multiple iterations to achieve accuracy. On construction sites, computers are usually optimized for daily project management tasks rather than intensive BIM processing, leading to hardware limitations that conflict with the demands of complex modeling.
3. Workset Division
BIM models used in construction management can contain tens of thousands of components, making it essential to divide the model into manageable worksets. If worksets are too large, synchronizing and saving central files becomes slow and prone to errors, severely hindering progress. Conversely, if worksets are divided too finely, errors between them may go unnoticed until the final BIM integration, resulting in extensive rework and project delays.
So, how many factors affect BIM modeling speed? These are the main points discussed here. As we continue working, more influencing factors will likely emerge. One thing is clear: BIM modeling is a meticulous, time-consuming process that requires extensive data input before the model becomes fully functional.
