Discussion of a Method of Collaborative Construction Project Information Management Based on BIM

With the development of information technology, many industries have greatly improved their production efficiency. At the same time, production efficiency in the construction industry has not only failed to grow, but is actually on the decline. The main reason for this problem is interoperability, which is the exchange and sharing of construction project information between the participants and the different application software in the project life cycle. At present, Building Information Model (BIM) is considered to be an effective way to solve the problems in the construction project life cycle. The integrated BIM information is a significant improvement in all processes where project participants have to use and communicate complex, accurate and interrelated construction project information. This paper first expounded the background, which is during the construction project life cycle management. The degree of information sharing and collaboration of construction units is low, which is the main reason for low efficiency in the construction industry. Then, a BIM-based information integration model is proposed. The information interchange of construction units is realized in this model. The efficiency of project management is improved.
