Innovative Application of BIM Information Technology in Intelligent Beam Yard of Expressway

The precast beam yard is a key temporary project in the construction of bridges, and its construction helps to realize the standardization, refinement, information and intelligence of the management of the beam yard. Relying on the prefabricated beam yard of the Beijing New Airport Expressway bridge, explore the information construction technology based on BIM technology, establish a digital model for production management, and track and monitor the construction process of prefabricated components, thereby realizing information construction. Using BIM technology to create a smart beam field integrating visual construction management, quality management, progress management and dynamic monitoring systems can not only improve the management level and work efficiency of the beam field, but also provide a reference for related project construction.
