Background
BIM (building Information modeling) originally originated in the United states and is commonly referred to as a building Information model in China. The method is characterized in that a three-dimensional digital imaging technology is used as a foundation, a plurality of modeling tools are integrated in BIM through a common standard (common IFC, IndustryFoundation Class), and real information of a building is simulated and simulated through digital information, so that relevant data of various engineering information of a construction engineering project is obtained, and the three-dimensional modeling system becomes a three-dimensional modeling system containing a large amount of building entity information and is an information set throughout the whole life cycle of the project. The research object of the BIM technology is a building entity, which is essentially a product of information development and is an information management technology used in engineering project management. In 2009, wisconsin, the first state government in the united states to require BIM for newly built large public construction projects in the state, the texas state facility committee also announced the requirement for the application of BIM technology to design and construction projects for state government investments. In 2010, the state government of ohio promulgated the BIM protocol, and the state traffic province of japan promulgated the BIM technology. The current use of BIM in japan has expanded nationwide and has risen to the level of government advancement. In europe and korea, various domestic government agencies have been dedicated to the establishment of BIM application standards. In the construction of this collective "sport" business, BIM is initiating a radical change from unprecedented cases.
The BIM technology is introduced from 2003 in the domestic engineering construction industry, the current application is mainly designed companies, various BIM consulting companies, training institutions, government and industry associations also begin to pay more and more attention to the application value and significance of the BIM. At present, the scholars of China also do a lot of work on the basic theory and practical application of BIM. On the aspect of basic theory, Zhang Jianping and the like. The system comprehensively applies the international industrial standard of the building industry, establishes a building property information model and a data exchange interface based on the standard, and realizes the information exchange and sharing of the building property management stage, the design stage and the construction stage; in the design field, the BIM technology is applied to a large number of engineering practices, whether structural members collide or not is accurately checked, in the construction aspect, people utilize the BIM technology to carry out risk management and dynamic simulation of the construction process, engineering rework caused by artificial factors is prevented, and engineering funds are saved; in the development and utilization of urban underground space, the prior research mainly focuses on the application of the BIM technology in the aspect of urban underground traffic. The construction of a subway station is taken as an example to research the application of BIM in underground construction engineering, the construction of a No. 11 line second-stage stone dragon road station of sea rail transit such as Jinyong and the like is taken as an example, the application of BIM technology in subway installation engineering is introduced, the application of BIM technology in subway construction safety is briefly analyzed by Zhang Fang and the like, the application of BIM in underground engineering in a square in front of a Jinan West station is analyzed by Dalin and the like, the application of BIM technology in the construction of east Hangzhou stations and Yinchuan train stations is researched by Ganggang and the like (similar case: Wuhan International Brookfield center. the application of BIM in operation and maintenance management, the operation and maintenance management visualization, the positions of electromechanical, heating and ventilation, water supply and drainage, strong and weak electricity and the like in debugging, prevention and troubleshooting are determined by using a completed three-dimensional BIM model, emergency management decision is simulated by using the BIM model, evaluating the loss caused by the emergency; inquiring spatial information, namely inquiring information of areas, regional inner spaces, rooms and members in three-dimensional modeling by using bim technology; and managing equipment information, and inquiring and maintaining related facility information of the main body and the enclosure structure. The source is as follows: hundred degree library: https:// wenku.baidu.com/view/0150b71a580102020740be1e650e52ea5518ce9d. html). In summary, the technical problems in the prior art are as follows: 1. the main problems to be solved currently in the operation and maintenance of the commercial complex are effectively dispersion of the logistics equipment of the commercial complex, high management requirements and high management difficulty, and the digital, visual and intelligent construction for promoting the logistics service of equipment of large-scale complex commercial complex facilities and the operation management of the logistics facilities is accelerated; the data butt joint of a Building Information Model (BIM) and a logistics facility operation management platform is solved, and the visual display of the operation state is realized; and carrying out spatial data combination early warning on operation events which may occur in equipment facilities. 2. Problems faced in the popularization and application of the BIM technology are as follows: (1) BIM will become the mainstream technology of the next generation, but the environment for popularizing and applying the BIM is still to be mature, compared with the foreign countries, the existing building industry system in China is not uniform, and a relatively perfect BIM application standard is lacked, and the legal responsibility boundary of the industry for BIM is not clear, so that the environment for popularizing and applying the BIM in the building industry is not mature enough, and a plurality of experts at home and abroad think that the difference of the existing building industry system, the domestic standard and the standard is a barrier to urgently breaking through for popularizing the BIM application; (2) project operation lacks overall management, BIM application encounters 'cooperation' dilemma, collaborative design is lacked in the BIM application process, particularly, in domestic project operation, project different stages, different specialties and participant information lack overall management, BIM related software relates to different specialties, BIM ideas and technologies provide a new platform for collaborative design, and whether project collaborative design is available or not is crucial to whether the value of BIM can be fully realized or not; (3) the BIM concept extends through the project life-cycle, but lacks efficient management integration at each stage. The BIM brings visualization technology to designers, but the visualization technology is only one layer of the BIM, and the essence of the BIM lies in that information runs through the whole life cycle of a project, so that the BIM has great significance to the construction of the project and the comprehensive integration of later-stage operation management; relevant researchers research shows that in a building engineering project information system, BIM has the advantages of integrated management and full-life cycle management; the application of BIM in China at present basically depends on individual complex projects or special requirements of certain owners, the full-life cycle integration advantage of BIM information is fully exerted, the deep application of BIM is realized, and much work is required; (4) the field is also lacking in further applications. From the domestic and abroad, the commercial complex project is a complex public building, which has great potential for applying the BIM, especially the combination with operation and maintenance, but the domestic current application mainly focuses on the shortage of the application depth in the construction stage. For this reason, a corresponding technical scheme needs to be designed for solution.
