Application of BIM Technology in the Expansion and Reconstruction of Municipal Projects

摘要

With the development of society, the roads planned and designed in the past can't meet the daily traffic demand nowadays. Traffic congestion has become a common problem in urban development. The existing roads also involve the urban waterlogging in the rainy season in the south, so the existing road reconstruction and expansion projects are imminent. In the municipal renovation and expansion projects, the traditional design method has been unable to meet the actual construction requirements. At the same time, the emergence and application of building information model (hereinafter referred to as "BIM") technology has brought new opportunities and vitality to the development of engineering construction industry. However, the application of BIM technology in municipal roads can not be better developed and promoted in this field due to its less application and scarcity of actual combat projects. Aiming at the problems existing in the traditional pipeline integrated design, this paper introduces BIM technology into the actual project, and optimizes the design scheme by using the functions of three-dimensional visualization information, information sharing, collision inspection and scheme optimization of BIM technology, which reduces the design changes of the project, guarantees the project schedule and saves the project cost. At the same time, in the process of building the three-dimensional model, the process of virtual construction is realized, the problems that may arise in the construction are found in advance, and solved to make the design more reasonable.
