The article discusses how using Building Information Modeling (BIM) can help detect clashes in construction plans early on, preventing design errors and cost overruns. The researchers used BIM tools like Autodesk Revit and Navisworks Manage to create models and identify clashes in a Malaysian police headquarters building project. The study found that BIM is effective in detecting clashes among building elements, allowing for constructability issues to be addressed before construction begins. This helps control project costs, save time, and ensure a smoother design process for better buildings.
