In order to realize the automatic production of precast components, the information-based automatic processing technology integrating information processing (CAM) and MES technology can directly import the BIM design information into the factory central control system and convert it into the production data information that can be read by mechanical equipment.

Factory production link is a unique link in the construction of precast buildings, and it is also the stage in which components change from design information to entity.

Especially under the EPC project general contracting management mode, the role and advantages of information application of precast buildings based on BIM are becoming more and more prominent.

In BIM integrated design, each discipline of architecture, structure, electromechanical and decoration builds the model in the platform design software according to the unified base point, grid, coordinate system, unit, naming rules, depth and time nodes.

Under the EPC general contracting mode, based on the sharing and collaborative core value of BIM, with the progress plan as the main line and the BIM model as the carrier, share and integrate the on-site assembly information, design information and factory production information, so as to realize the digital, refined and visual management of project progress, construction scheme, quality and safety.

BIM information management under EPC mode involves the information application of relevant disciplines, links and businesses of engineering projects.

Field assembly stage is the process of building entities from scratch in the whole life cycle of precast buildings.

The concept of BIM Technology Collaboration and integration is highly integrated with the idea of integrated construction of precast buildings.

The concept of BIM Technology Collaboration and integration is highly integrated with the idea of integrated construction of precast buildings.

The application of BIM information technology the realization of “integration of design, production and assembly” of precast buildings requires the application of BIM information technology in the process of design, production and assembly.

The factory production information management system can combine RFID, QR code and other Internet of things technology and mobile terminal technology to realize the information management of production scheduling, material procurement, mold processing, production control, component quality, inventory and transportation.

At the same time, under the EPC general contracting mode, the application of BIM Technology can effectively enhance the collaborative management ability of EPC project team and realize intelligent construction.

Bim-erp information management application BIM information management of precast buildings takes the building information model as the information source of the project.

BIM based information management platform is to establish a data center as the computing service support for BIM design, production and assembly information of engineering projects.

Through the factory central control system, the component information in BIM model is directly transmitted to the production equipment for automatic and accurate processing, so as to improve the operation efficiency and accuracy.

Combined with the development of BIM Technology and the systematic characteristics of precast buildings, with the help of Bim and other information technologies, the information barriers of all links, disciplines and participants are opened, so as to promote the implementation and promotion of integrated construction of precast buildings and realize the deep integration of building industrialization and information in China.

Through the application of BIM integrated design technology, BIM factory production technology and BIM on-site assembly technology, the digital information of design, production and assembly will be continuously generated in the implementation process of the project, realizing collaboration.

Complete BIM model information and business information related to engineering construction are required as basic data support.

Combined with the 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.

In addition, each discipline needs to cooperate with its own design process, continuously enrich BIM model information through collaborative work, and finally form a comprehensive design model integrating the design information of each discipline.

Especially under the EPC project general contracting management mode, the role and advantages of information application of precast buildings based on BIM are becoming more and more prominent.

Through this platform, enterprise resource database can be formed and collaborative office can be realized.

At the same time, each specialty can also select matching components and parts from the building standardization, serialization component family library and part library to build models, so as to improve the standardization degree and efficiency of modeling.

Through the integrated information management platform based on BIM, the integrated management of EPC project construction can realize the information management of procurement, cost, progress, contract, materials, quality and safety in the whole process of precast building design, production and assembly, and finally realize the effective allocation of project resources in the whole process.

BIM based precast building informatization application advantages BIM Technology can connect architecture, structure, electromechanical and decoration disciplines more effectively, form BIM integrated design, further strengthen the coordination of various disciplines, reduce design changes caused by “mistakes, omissions, collisions and inaccuracies”, improve design efficiency and design quality, and reduce costs.
