This article explores dynamic control in the entire life cycle construction of modern prefabricated buildings from the perspective of "design production construction" general contracting. Based on BIM technology, an application model for the full life cycle management of prefabricated buildings in "design transportation installation construction operation and maintenance" is constructed. The implementation process of prefabricated buildings is systematically and finely managed through information technology application, systematized into a building information platform, Provide certain suggestions to promote the development of information technology in prefabricated buildings, and assist in the intelligent construction of prefabricated buildings during the current upgrade period of "China Construction".
