Geometric model lightweight processing method in BIM for operation and maintenance management

Abstract

The invention discloses an operation and maintenance management-oriented geometric model lightweight processing method in a BIM, and the method comprises a full-life-cycle framework which is composed of an application layer and a carrier layer, and the application layer and the carrier layer communicate with each other; the carrier layer is a key layer of full-life-cycle application of a project and is divided into a design model, a construction model and an operation and maintenance model according to the full-life-cycle stage, and the design model layer is a source of whole basic data. Under the cooperation of the application layer and the carrier layer, deep optimization is carried out through the design model, the construction model and the operation and maintenance model, the complete continuity of the platform architecture is perfected, the scheme rationality is improved, and errors and missing collision are reduced, so that the design quality is improved; the construction stage has the characteristics of visualization, coordination, simulation, optimization, accurate cost, controllability and the like, and has the characteristics of avoiding or reducing construction conflicts, controlling site conditions as early as possible, better performing construction management, improving working efficiency and the like while what you see is what you get.

Description

technical field [0001] The invention relates to the technical field related to building information models, in particular to a method for lightweight processing of geometric models in BIM oriented to operation and maintenance management. Background technique [0002] In order to implement the requirements of the Ministry of Housing and Urban-Rural Development's "Notice on Promoting the Application of Building Information Modeling Guidelines" and the General Office of the State Council's "Guiding Opinions on Promoting the Construction of Urban Underground Comprehensive Pipe Gallery", the promotion of building information modeling (BIM) technology in The comprehensive promotion and in-depth application in the construction of comprehensive pipe corridors will enable BIM technology to better serve the construction of pipe corridors. [0003] The early construction of the comprehensive utility gallery is large in scale, full of specialties, and many participating departments. The...

Problems solved by technology

[0005] Traditional installations have the following shortcomings: lack of work standards for BIM implementation and application, which can easily lead to unreasonable organizational structure, lax management, and unclear requirements; lack of consideration for BIM data transfer between different stages, resulting in a large amount of repetitive work and unsystematic; The correlation between data and models in the operation and maintenance platform is not high, and the data asset value of BIM is not fully utilized
