Many people consider drawing construction plans to be a simple skill. However, when it comes to BIM (Building Information Modeling) applications, many underestimate the complexity, often dismissing BIM modeling as low-level and insignificant. Frequently, during company meetings, the question arises: “Who can do something others cannot?” Unfortunately, the quality of construction drawings is often unsatisfactory, and the so-called BIM models tend to encounter various issues during practical use.
Currently, the engineering and construction industry relies on two main types of graphical outputs to support different tasks. The first type is construction drawings, which are created for practical use on-site. The second type includes visual models designed primarily for viewing purposes, such as renderings and animations. BIM models represent a third category, which is not yet widely adopted. These are information-rich models developed for actual use in project management and execution.
In construction drawings and visual models, as long as the final presentation meets the requirements, minor inconsistencies—like having three lines beneath one line, several blocks behind a surface, or elements that appear connected but are not—are generally acceptable. However, in BIM models, such discrepancies make the model unusable because BIM relies on accurate, data-rich representations where each element’s properties and relationships must be precise and reliable.
From extensive experience reviewing and proofreading BIM models across various enterprises—including design firms, construction companies, and specialized BIM consulting firms—it is clear that even without tackling the complex challenges of planning, organizing, and integrating BIM models for large-scale, difficult projects, creating a truly usable BIM model is far from a simple task. It requires more than just basic BIM modeling skills.
