RFID and CCTV-Based Material Delivery Monitoring for Cable-Stayed Bridge Construction

摘要

The effective management of construction materials is critical to the successful execution of large-scale infrastructure projects. A cable-stayed bridge construction, for which diverse and complex structural components must be monitored, is no exception. To improve the effectiveness and efficiency of bridge-component management, we developed a material delivery monitoring system using closed-circuit television (CCTV) and radio frequency identification (RFID) technologies. The RFID technology was used to identify the structural components of the cable-stayed bridge; CCTV cameras acquired site image data that helped field engineers confirm the delivery of construction components. The RFID information and image data were saved to a main server database for systematic management of construction materials. A case study conducted at a cable-stayed bridge construction site verified the applicability and capability of the developed system. The system has considerable potential to significantly improve the current practices of construction material delivery monitoring in large-scale infrastructure projects by helping construction engineers simplify the complex process of tracking diverse structural components.
