Most of the precast components are non-polluting building components, which meet the requirements of green construction today; Compared with traditional architectural design, the resources wasted in the actual construction of precast architectural design are lower and the cost consumption is more reasonable, which can allocate more costs to other aspects and improve the overall quality of the building.

The precast building is a modern construction method formed by the on-site mechanical assembly of various functional modules.

The development status and problems of precast buildings (1) The volume of precast components is large, the automation of precast precast plants is insufficient, and the production efficiency is low.

However, under the traditional mode, there are problems such as high error rate of information interaction, low efficiency of collaboration, and poor professional integration in each stage of work, resulting in the failure to guarantee the safety and quality of the building.

As a digital application and information management tool, BIM technology affects not only the tools and technologies used by engineers, but also the production, management and operation methods and processes of enterprises, and even the industrial chain structure of the whole industry.

The precast construction project is huge, involving complex disciplines and diverse technologies.

It has effectively dealt with the obstacles of information transmission, and put forward the interactive three-dimensional visual management between data and information.

(5) The products and services of the precast building industry lack standardized management.

It can improve the informatization level of precast buildings and give full play to the advantages of modern integrated construction of precast buildings.

Through this service platform, multiple parties can participate in the process of infrastructure construction and complete the information integration of various disciplines, stages and regulators.

At present, the construction personnel of precast buildings have less experience, and the industrial standards and technical specifications are not perfect.

The internationally recognized concept of BIM is to divide BIM into four attributes: visualization, parameterization, integration and process.

For the collision of components, reinforcement, pipes, etc., it is necessary to quickly sort out the bill of materials through this technology, which will be beneficial to the calculation results of the bill of quantities of the precast building system.

Most precast construction plants are still using two-dimensional design drawings for design and production.

The production of precast components requires a series of production processes, such as formwork erection, reinforcement binding, vibration, pouring, and maintenance.

As a new design method, the precast architectural design method has a good market prospect.

(3) The precast building construction personnel are insufficient, the site construction efficiency is low, and the construction quality is difficult to guarantee.

The design stage requires the pre-integration of the whole process elements, and requires a more refined design and management concept.

At the design stage, BIM technology must meet the following three points..

At present, most of the precast construction plants have insufficient automation level, which requires a lot of manpower and material resources, low production efficiency, and difficult to ensure accuracy.

The precast building has the characteristics of “standardized design, factory production, assembly construction, integrated decoration, information management, and intelligent application”, which can promote the reform and upgrading of China’s construction industry, and improve the level of industrial intelligent manufacturing and information management of the construction industry.

This paper analyzes the design of intelligent engineering management system for precast buildings based on BIM technology for reference.

It is a new type of design and a long-term sustainable building design type.

(4) The integration level of design, production and construction is insufficient, and the coordination of all links is insufficient.

Compared with traditional buildings, the product design process and project management of precast buildings are more complex, but the industrial design level of precast buildings is lower than that of traditional buildings.

Most of the construction personnel learn while constructing, and the construction quality is difficult to guarantee.

BIM carries the basic information of the project, the spatial composition information, the professional system information, and customizes other characteristic information according to the project construction requirements and operation characteristics, so that the precast building module can be fully digitized; With the help of EPC general contracting management mode, we can solve the problem of decentralization of management rights and responsibilities, make the relationship of the whole industrial chain more centralized, and make the whole process of design, production and construction more closely linked, so as to provide more timely, accurate, efficient and standardized information exchange process for the project, and effectively improve the level of project refined management and engineering construction.

The so-called precast building design refers to the use of precast components for building structures.

Click the “blue letter” to pay attention to our building information model, which is an intelligent expression of the physical and functional characteristics of engineering buildings.

With the rapid development of the construction industry, the requirements of all walks of life for project management have gradually increased.

1 Overview The construction industry is the pillar industry of China’s economy.

The traditional architectural design method has been replaced by the precast architectural design method.

When the required design cannot keep up, the products produced by the factory cannot meet the expected effect of the purchaser, resulting in the unsmooth cooperation between the upstream and downstream of the precast building industry chain.

The application value of BIM technology in the precast building system In the design process of the precast building system, BIM technology needs to complete various functions such as the separation of precast components, the construction of solid models, and the post-impact inspection, and meet the different needs of different models by completing various professional capabilities.

(2) The level of digital design is insufficient, and the efficiency of component design is low.

Compared with traditional building design types, it has great advantages.

2.

It needs more effective collaborative technical means and effective quality and safety supervision methods to improve production efficiency and highlight the value of precast construction.

In recent years, China has actively explored the industrialized construction mode of new buildings with precast buildings as the main mode.

BIM is the abbreviation of Building-Information-Modeling, which is the digital information expression of building physical and functional characteristics, and generates dynamic data value in the creation, use and management of building information model.

At present, the digital design software of precast buildings in China is not perfect, the degree of standardization is low, and the use cost of the software is high.
