Abstract. The rapid development of information technology has brought several innovations to the field of civil engineering. BIM (Building Information Modeling) technology places emphasis on information integration and the establishment of a database. It also aims to realize the building life-cycle management. BIM technology is exerting a significant and profound impact on the design, construction, management, operation, and maintenance of building projects. In this study, the value of BIM in construction projects was analyzed, and the significant meaning of this study was elaborated. BIM standards and the data standard of IFC were discussed, and the important concepts of 4D-BIM and 5D-BIM were also presented. The key technologies like parameterization, visualization, geographic information system, building life cycle management, and clouding computing were analyzed. Furthermore, the mechanical behaviour of the building was analyzed, and the value of BIM in construction was expounded. Particularly, the application of BIM in bidding, BIM virtual construction, clash detection, and refined calculation about resources as well as materials were analyzed in this paper. Also, the construction dynamical management system of 4D-BIM was discussed. Finally, the coordination, which acts as an important issue between the BIM design and BIM construction, were analyzed comprehensively.Keywords: BIM technology; design construction; simulation; schedule; building.
IntroductionThe 21st century marks the advancement of technology, the era of rapid development of information technology, and the building information modeling (BIM, Building Information Modeling). As a building project in the field of a new technology, BIM is not only the product of the birth of the information age. However, it has brought about social productivity and has met urgent developmental needs. Through external factors such as Locations and local design conditions, BIM will form the architectural design of intelligent 2D and 3D object, which is connected to a virtual building in a database. Therefore, the database is associated with certain buildings, single, integrated, and covers all building information source [1].BIM's integrated data information covers all phases of the building lifecycle, including the planning phase, design phase, construction phase, operation and maintenance phase, predictive control stages, etc. [2; 3]. BIM is often likened to the DNA of a building [4]. Throughout the design process, especially in the early architectural design, more detailed data information has been included, since the construction industry has become a growing trend [5].BIM is an important architectural design process, which is used to meet the requirement of the data. This requirement is the building information model to show a unified description of a building. Consequently, BIM can greatly enhance the design, construction, and building lifecycle of information flow in various stages. Thus, these include the building lifecycle, architects, equipment engineers, ...
