Different kinds of precast beams, slabs, columns, stairs, internal and external wall panels and other practices are set to ensure the stability of design and production, facilitate mass production of components, improve production efficiency, and speed up construction, It also has sufficient guarantee for quality stability.

The traditional design scheme is mainly presented in two-dimensional drawing mode, while the main feature of BIM Technology is visualization and unified display of information parameters in three-dimensional components, which facilitates accurate design of components and avoids design errors.

During the design of the lifting point position, attention shall be paid to the collision inspection to avoid the conflict between the lifting point and the reserved hole.

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

Attention shall be paid to the accuracy of the reserved parts and holes to ensure that they are carried out in accordance with the design requirements and the construction scheme, without affecting the implementation of subsequent processes.

Traditional buildings mainly use cast-in-place method, while the construction site of precast buildings mainly uses hoisting technology, that is, according to the design drawings and construction schemes, each component is hoisted to the designated location for on-site installation or connection.

The transportation moving line model can be established according to the production and construction address to analyze the problems of transportation vehicle number, route, transportation vehicles and vehicle selection, so as to provide data reference for resource allocation.

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

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.

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

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 the coding with RFID technology to realize the dynamic management of component production and transportation, and can use the 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 for 3D mode transportation environment to avoid risks during transportation and ensure transportation quality.

Before hoisting, the BIM building model can be used to simulate the construction scheme and fully reflect the construction process in three-dimensional form, so as to facilitate the actual operation of technicians and operators and achieve the role of visual technical disclosure.

Therefore, BIM Technology can play an important role in hoisting nodes.

2、 Application of BIM Technology in PC component transportation quality management since precast components need to be transported within a certain distance to the construction site after 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.

If the components completed in production are damaged due to improper transportation, on the one hand, rework and repair will affect the progress of the construction period, on the other hand, hidden dangers will be buried for the quality and safety of the building.

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

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

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

3、 Application of BIM Technology in PC component storage quality management after the precast components arrive at the construction site, the layout of storage, hoisting, etc.

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

1、 The application of BIM Technology in the quality management of standardized component manufacturing the main structural form of precast buildings is the mode that precast components are produced in the factory and transported to the construction site for on-site hoisting construction.

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

Therefore, full attention should be paid to the transportation of precast components.

Therefore, in the construction process, Hoisting work has an important impact on the quality of precast buildings.

After inputting the component information into the information system through chip implantation, the process of component stacking and construction can be directly simulated from the informatization software or platform, so as to facilitate the preparation and disclosure of construction scheme by operators.

As certain principles must be followed in hoisting components before reasonable installation, there is a special construction scheme for special nodes, and due to the diversity of component forms, there are higher requirements for mechanization and higher requirements for quality and safety.

The informatization function of BIM Technology in the storage link mainly lies in the identification and positioning of components.

In addition, the management software and plug-ins for transportation planning can be developed based on BIM Technology.

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

shall be reasonably arranged according to the site conditions, and the construction facilities and equipment shall be reasonably arranged according to the production demand.

4、 Quality management application of BIM Technology in hoisting process the biggest difference between precast buildings and traditional buildings lies in the main work content of the construction site.
