On December 29, 2016, the EBIM cloud platform developed by Yizhu Information Technology (Shanghai) Co., Ltd. assisted the commercial residential project on plots H3-02 and H3-05 in Zhaoxiang Town of Shanghai Construction Engineering First Construction Group Co., Ltd. The general construction of the project With an area of 217,578 square meters, this tender section is composed of 30 PC stacked residential buildings, and the structure is short-leg shear wall structure + prefabricated exterior wall system.
Clean and tidy project site
This project mainly uses the EBIM cloud platform for information management of prefabricated PC components, and uses active RFID electronic chips + two-dimensional codes to locate and track the components throughout the process.
Information Management of PC Components
They use active RFID electronic chips to track the components in the whole process, and link the electronic chips with the Internet and cloud storage platforms to collect and summarize the production and installation data and images of the whole process, and use the cloud control platform to All data and images are managed and the follow-up construction is guided.
The processing plant prints the QR code through the model and enters the information into the RFID chip
Active RFID chip + QR code application process
EBIM cloud platform construction
The BIM model of the Qingpu Zhaoxiang project is uploaded to the EBIM cloud platform, and the BIM model is used for on-site collaborative application, PC component process tracking, and on-site engineering data and PC component connection viewing through the EBIM platform.
The project department communicated with Baoye PC Component Factory and confirmed that the project will track and record the component process steps through the active chip. The process includes the completion of component processing, the component entering the yard, the component leaving the yard, the component entering the project, and the component yard (on-site).
QR code printing
The component factory and the project department are equipped with a QR code printer, and the processing factory sends someone to print the QR code of the PC component. By selecting unit buildings, floors, and component types to print QR codes in batches, the work of inputting component information in excel and printing QR codes one by one is reduced. The two-dimensional code is pasted on both sides of the PC component of the processing plant. The production staff of the processing plant associate the chip with the component by scanning the two-dimensional code. After the associated information is synchronized to the server, the platform automatically records the process steps of the component production. On-site staff can view the PC component process information by scanning the QR code, and add the construction process information to the PC component.
Application of active RFID chip
The project uses active RFID chips for PC component tracking, which can automatically record the process status of PC components. The chip adopts the form of plug-in, which can be used in multiple projects repeatedly after being put into use at one time, saving project management costs.
detector
Active chip receivers are installed at the gate of the processing plant yard, the gate of the project department, and the component yard. When the PC component with the chip passes through the gate, the component information is automatically collected to the cloud platform. EBIM PC terminal, mobile terminal and professional handheld terminal can view the progress status of the component.
This time, Shanghai Construction Engineering applied the EBIM cloud platform to control the process of PC prefabricated components, reducing the management staff’s energy investment in component schedule management; solving the problem of difficult component yard management caused by multiple component yards; PC prefabricated component specific information and The viewing of data and drawings ensures the accurate installation of PC prefabricated components; the application of topics, forms and other functions improves the efficiency of on-site problem feedback. During the application process of the project, Shanghai Construction Engineering put forward reasonable suggestions for the EBIM cloud platform, and EBIM products are constantly improving.
