The main structural form of precast buildings is the mode of completing the construction by transporting precast components to the construction site for on-site hoisting after they are produced in the factory.

In the transportation stage, BIM technology can carry out information-based dynamic management of component information, code and identify the category, size, location, quantity and other parameters for each component from the early design, and combine coding with RFID technology to achieve dynamic management of component production and transportation, and use BIM integrated management platform to share component information, All relevant personnel can access the real-time production and location of components according to their authority, and use BIM technology to conduct 3D mode transportation environment to avoid risks in the transportation process and ensure the transportation quality.

In order to ensure that the precast components produced by the factory meet the quality requirements, quality management should be carried out from the source, that is, quality control should be carried out from the design stage.

4、 The application of BIM technology in quality management during hoisting The biggest difference between precast buildings and traditional buildings is the main work content on the construction site.

At the same time, it should be noted that for special components with complex structure, large volume and other special components, it should also be considered that they will not be damaged by the construction in the storage link, and the overweight components should be considered to strengthen the site, In addition, space for component turnover shall be reserved for the position of hoisting machinery in the later stage.

The reason why BIM technology can achieve fast and accurate design is that it has a relatively complete family library.

Therefore, we should pay full attention to the transportation of precast components.

2、 The application of BIM technology in the transportation quality management of PC components.

If the completed components are damaged due to improper transportation, on the one hand, rework and repair will affect the construction period, on the other hand, it will also lay hidden dangers for the quality and safety of buildings.

Therefore, in the construction link, The hoisting work has an important influence on the quality of precast buildings.

The traditional buildings mainly use cast-in-situ method, while the construction site of precast buildings mainly uses hoisting technology, that is, according to the design drawings and construction scheme, each component is lifted to a designated location for on-site installation or connection.

The warehousing sequence is reasonably arranged according to the sequence of construction hoisting.

The traditional design scheme is mainly presented in 2D drawing mode, while the main feature of BIM technology is that visualization and information parameters are displayed in 3D components, which is convenient for accurate design of components and avoids design mistakes.

3、 The application of BIM technology in PC component storage quality management When precast components arrive at the construction site, storage, hoisting and other layout should be reasonably arranged according to the site conditions, and construction facilities and equipment should be reasonably arranged according to production needs.

to ensure that they are carried out in accordance with the design requirements and construction scheme, without affecting the development of subsequent processes.

After the BIM technology and RFID technology are adopted for the preliminary design, component production, transportation and storage, the components have unique codes, and the classification and positioning are more accurate, which is convenient for hoisting.

Attention shall be paid to the accuracy of reserved parts, cavities, etc.

Because the hoisting components can only be reasonably installed according to certain principles, and there is a special construction scheme for special nodes, and because of the diversity of component forms, the requirements for mechanization level are higher, and also higher requirements for quality and safety are put forward, therefore, BIM technology can play an important role in hoisting nodes.

In addition, it is also possible to develop management software and plug-ins for transportation planning based on BIM technology, establish a transportation dynamic line model according to production and construction sites, analyze the transportation vehicle number, route, transportation vehicles and vehicle selection, and provide data reference for resource allocation.

The application of BIM technology in the quality management of standardized component manufacturing.

At the same time, attention shall be paid to the location of lifting points, which shall be lifted in accordance with relevant safety operation specifications to ensure the safety of lifting construction..

Therefore, compared with the traditional construction and production mode, the primary production link of precast buildings is in the factory.

After the component information is input into the information system by implanting chips, it can directly simulate the component stacking and construction process from the information software or platform, which is convenient for the operators to prepare and disclose the construction scheme.

Different types of precast beams, slabs, columns, stairs, interior and exterior wall panels are set up to ensure the stability of design and production, facilitate mass production of components, improve production efficiency, and speed up construction, The quality stability is also fully guaranteed.

The informatization function of BIM technology in the warehousing link mainly lies in the identification and positioning of components.

Because precast components need to be transported to the construction site within a certain distance to complete the assembly work after the completion of production, transportation is also an important link in the production and construction of precast buildings and plays an important role in the quality control of buildings.

When designing the position of lifting points, attention shall be paid to collision inspection to avoid conflicts between lifting points and reserved holes.

As the important feature of precast building components is standardized production, the BIM technology can be used to carry out standardized design in the design, and the information of the components can be completely presented, and the information-based data can be directly connected with the component manufacturers to improve the efficiency of design and component production.

At the same time, lifting points shall be reasonably set in precast members according to relevant specifications, standards and other requirements at this stage, so as to facilitate the on-site lifting construction of later members.

Before hoisting, the BIM building model can be used to simulate the construction scheme, and the construction process can be fully reflected in three-dimensional form, which is convenient for the technical and operator to carry out the actual operation, and can also achieve the role of visual technical disclosure.

Designers can conduct secondary development on the basis of the software family library, constantly improve the component library, and even establish the enterprise production component library.
