Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of BIM modeling and construction, and particularly relates to a method for establishing an operation and maintenance model based on BIM technology. BACKGROUND

[0002] BIM technology is a data-based tool applied to engineering design and construction management. Through a parameter model, various project-related information is integrated, shared and transmitted in the whole life cycle of project planning, operation and maintenance, so that engineering and technical personnel can correctly understand and efficiently respond to various building information, and provide a basis for collaborative work for design teams and various construction subjects including building operation units, thereby playing an important role in improving production efficiency, saving costs and shortening construction period. The BIM model has gone through several stages from modeling to construction management, and now to the operation and maintenance model. The BIM model established in the construction stage needs to be converted to the operation and maintenance BIM model in the later stage of the project. The traditional operation and maintenance model is a collection of various professional models after model establishment based on two-dimensional drawings, collision checking and final adjustment. Nowadays, the operation and maintenance model has developed from the traditional two-dimensional model to the current three-dimensional visual model based on BIM. However, in the process of converting the construction model established in the construction stage to the operation and maintenance model, the modeling requirements of the two stages are different, which leads to the fact that the model established in the construction stage cannot be continuously used in the operation and maintenance stage, so the model needs to be re-established in the operation and maintenance stage, resulting in a large amount of repeated work, which not only wastes labor but also makes the work efficiency low.
