BIM contrasts with traditional CAD by embedding intelligence (e.g., material specs, costs) and enabling real-time updates. Benefits include error reduction (via clash detection), cost savings, and sustainability analysis. Challenges include software compatibility, upfront costs, and cultural shifts. Stakeholders (architects, engineers, contractors) use BIM to streamline workflows, improve accountability, and deliver smarter, future-ready projects. This foundation underpins BIM’s role as a catalyst for modernizing construction through data-driven collaboration.
