Smart-Tracking Systems Development with QR-Code and 4D-BIM for Progress Monitoring of a Steel-Plant Blast-Furnace Revamping Project in Korea

Blast furnace revamping in the steel industry is one of the most important works to complete the complicated equipment within a short period of time-based on the interfaces of various types of work. P company has planned to build a Smart Tracking System based on the wireless tag system to comply with the construction period and reduce costs, ahead of the revamping of blast furnace scheduled for construction in February next year. It combines detailed design data with wireless detection technology to grasp the stage status of design, storage, and installation. Then, it graphically displays the location information of each member to the plan and the actual status in connection with Building Information Modeling (BIM) 4D Simulation. QR Code is used as a wireless tag to check the receiving status of core equipment considering the characteristics of each item. Then, DB in the server system is built, status information is input. By implementing BIM 4D Simulation data using DELMIA, the information on location and status is provided. In terms of logistics digitization, the system’s features allow suppliers to monitor the real-time status of the 4D system provided on a Web basis, enabling suppliers to accurately identify and supply the delivery times for the facilities they need to manufacture and supply. Besides, the project progress control can be managed quickly and accurately by identifying the location of major delivered facilities in real-time to maximize the efficiency of construction, and by identifying the status information of major facilities, i.e. installation status in real-time. This digitalization ultimately results in savings in the manpower involved in the project and contributes to lower investment costs as a whole.
