Abstract: Boeing 737Max Aircraft Completion and Delivery Center Custom-built Workshops and Supporting Facilities Construction project has many typical characteristics, such as large area, multiple disciplines, comprehensive integration, high coordination requirement between each discipline, Tight construction schedule, complex site and traffic, multiple and strict management, high standards, difficult to make design development for construction, To guarantee the delivery schedule, BIM team was founded to implement BIM technology for modeling and design development. Also, BIM models have been used as reference for construction. Many BIM implementation such as integration platform, drawing review, 3D site layout, construction simulation, pipeline coordination, UAV terrain scanning, fine decoration design development through VR, and 3D laser scanning, which had obtained many good benefit in safety, quality, progress, cost, and etc. of the construction project. This was made truly a "cost reduction and efficiency increase, science and technology innovation". This paper will mainly introduce the application of BIM technology in the general contracting management of Boeing 737 Completion and Delivery Center project, aims to provide reference for similar large and complex projects in the future.
