BIM (Building Information Modeling) is a digital planning method used in lean construction to plan and manage construction projects more efficiently and accurately. BIM makes it possible to create a virtual model of a building and to store and manage all relevant information, such as materials, costs, and schedules, in a central location.

The main principles of BIM in lean construction are:

• Digital planning: BIM enables detailed and precise planning of construction projects by centrally managing all information and allowing changes to be made in real time.
• Efficient construction management: Centralized storage and management of all project information enables construction management to respond to problems and make decisions more quickly and efficiently.
• Collaboration: BIM promotes collaboration between all project participants, as information is easily accessible and communication barriers are broken down.

The advantages of BIM in lean construction include:

• Cost savings: Precise planning and efficient project management can reduce costs and improve budget compliance.
• Time savings: BIM enables faster decision-making and response times, resulting in shorter construction times and faster project completion.
• Quality improvement: Digital planning and collaboration with BIM lead to higher quality in the planning and execution of construction projects.
