BIM is an intelligent 3D design process, which architects use to create a digital model of a building, embedding data regarding materials, schedules, costs, and more. Instead of working from separate 2D plans, a BIM model serves as the “single source of truth” for the project. The architects and engineers-and even the contractors-work from that same updated model in real time, drastically reducing miscommunication. That integrated approach pays off in smoother projects and fewer mistakes.
