As-built BIM models are essential in construction, providing accurate representations of a project's status that enhance collaboration, reduce errors, and improve resource efficiency. They play a critical role in all project phases, from pre-construction planning to post-construction facility management, by allowing teams to visualize the project and integrate real-time changes. Emerging technologies like AI and cloud-based platforms are expected to further advance the use of as-built BIM for smarter, more efficient construction management.
