[transferred from BIM society] the idea of BIM Technology Collaboration and integration is highly integrated with the idea of integrated construction of prefabricated buildings, especially in the EPC project management mode, the role and advantages of BIM based information application of prefabricated buildings are more and more prominent According to the current development and advantages of BIM Technology, combined with the systematic characteristics of prefabricated buildings, this paper analyzes the application of BIM Technology in the whole process of integrated construction of prefabricated buildings under the EPC mode, and deeply excavates the application value of BIM Technology in prefabricated buildings through the application of BIM Technology and bim-erp management information, so as to boost the development of prefabricated buildings Integration and high quality development
. 
BIM Technology can effectively connect architecture, structure, mechanical and electrical, and decoration disciplines, form BIM integrated design, strengthen the collaboration of various disciplines, reduce the design changes caused by “error, leakage, collision, and accuracy”, achieve the improvement of design efficiency and design quality, and reduce the cost
. 
At the same time, the application of BIM Technology can effectively enhance the collaborative management ability of EPC project team and realize intelligent construction under the EPC general contracting mode
. 
The integration of informatization and industrialization promotes the application of BIM information technology in the integrated construction of prefabricated buildings
. 
The realization of “integration of design, production and assembly” of prefabricated buildings requires the application of BIM information technology in the process of design, production and assembly
. 
Through the application of BIM integrated design technology, BIM factory production technology and BIM field assembly technology, the digital information of design, production and assembly will be continuously generated in the implementation process of the project, realizing the cooperation
.
BIM design production assembly whole process technology application of BIM Technology in design in BIM integrated design, architecture, structure, mechanical and electrical, decoration professional according to the unified base point, axis, coordinate system, unit, naming rules, depth and time node in the platform design software to build the model
.
At the same time, each specialty can also choose the matching components and parts from the building standardization, serialization component family library and parts library to build the model, so as to improve the standardization degree and efficiency of modeling
.
In addition, each specialty needs to cooperate with its own design process
.
Through collaborative work, BIM model information is constantly enriched, and finally a comprehensive design model integrating the design information of each specialty is formed
.
The application of BIM Technology in factory production is a special link in the construction of prefabricated buildings, and it is also the stage when the component changes from design information to entity
.
In order to realize the automatic production of prefabricated components, the information-based automatic processing technology integrating information processing (CAM) and MES technology can directly import the BIM design information into the central control system of the factory, and transform it into the production data information that can be read by mechanical equipment
.
Through the factory central control system, the component information in BIM model is directly transmitted to the production equipment for automatic precision processing, which improves the operation efficiency and accuracy
.
Factory production information management system can combine RFID, two-dimensional code and other Internet of things technology and mobile terminal technology to realize information management of production scheduling, material procurement, mold processing, production control, component quality, inventory and transportation
.
BIM factory production technology application of BIM Technology in field assembly stage is the process of building entity from scratch in the whole life cycle of assembly building
.
Based on the shared and collaborative core value of Bim in EPC mode, with schedule as the main line and BIM model as the carrier, the on-site assembly information is shared and integrated
.
Through design information and factory production information, the digital, refined and visual management of project schedule, construction scheme, quality and safety is realized
.
Bim-erp information management application BIM information management of prefabricated building takes building information model as the information source of the project
.
Combined with ERP resource allocation plan at the enterprise level, cloud technology, RFID and other Internet of things technology and mobile terminal technology are used as information collection and application means to serve the integrated whole process management of EPC project general contracting mode
.
Bim-erp information management establishes an integrated information management platform based on BIM
.
The information management platform based on BIM is to establish a data center as the computing service support for BIM design, production and assembly information of engineering projects
.
Through this platform, the enterprise resource database can be formed and the collaborative office can be realized
.
Information management of EPC project construction BIM information management under EPC project general contracting mode involves the information application of engineering project related majors, related links and related businesses
.
It needs complete BIM model information and business information related to engineering construction as basic data support
.
Through the integrated information management platform based on BIM, the integrated management of EPC engineering construction can realize the information management of procurement, cost, schedule, contract, material, quality and safety in the whole process of prefabricated building design, production and assembly, and finally realize the effective allocation of project resources in the whole process
.
Conclusion the idea of BIM Technology Collaboration and integration is highly integrated with the idea of integrated construction of prefabricated buildings, especially in the EPC project management mode, the role and advantages of BIM based information application of prefabricated buildings are more and more prominent
.
With the help of Bim and other information technology, the information barrier of each link, each specialty and each participant will be broken through, so as to promote the implementation and promotion of the integrated construction of prefabricated buildings, and realize the deep integration of China’s construction industrialization and informatization.
