Whether CAD or BIM is “better” depend on the specific project requirements. CAD is typically preferred for straightforward drafting and 2D design, while BIM is favored for comprehensive management of complex projects with 3D models and integrated data for enhanced collaboration and efficiency. In complex, multi-discipline project delivery, BIM is often considered superior than CAD as it not only facilitates 3D modeling but also integrates data that informs specifications, schedule, cost, and project management, thereby enabling a more collaborative, efficient, and informed decision-making process throughout the construction lifecycle.
