A BIM Execution Plan (BEP) lays out how building information modeling (BIM) will be implemented on a construction project. It describes how data will be generated and shared in BIM files, who is responsible for various tasks, and how the project will be executed according to milestones to ensure quality and prevent disruptions. As BIM adoption increases, having a BEP is important to make sure all parties are on the same page and working collaboratively throughout the project lifecycle.
