Research on BIM-based Drawings Query and Feedback System with Smart Hand-held Devices

Recently, BIM technology has got a certain development in China, however, it is still lacking of abilities in application and operation, especially in drawings query and real-time data feedback and update on site. The paper is to develop a drawings query and feedback system using technologies of network, two-dimension code and database with smart hand-held devices on Android platform, with which the engineer is allowed to consult 3D drawings on site, and feedback timely and achieves data linkage between computer and handheld terminal. Through the case application, it shows that the hand-held terminal drawings query and feedback system can reduce information loss and improve the efficiency of project management to a certain extent.
