RADIOFREQUENCY IDENTIFICATION APPLICATIONS IN CONSTRUCTION-INDUSTRY

This paper provides information on radio-frequency identification (RFID) and its potential applications in the construction industry. RFID involves the use of miniature read/write transponders that are capable of storing data in harsh environments. These transponders can be used in situations where optical scanning is not practical because vision is blocked or because labels fall off or become unreadable due to dust, dirt, or other contaminants. The technology is currently used in several applications outside the construction industry (e.g., reading meters, preventing theft of store merchandise, tracking railroad cars and intermodal freight containers, collecting tolls, and performing agricultural and animal research), and is seen as having potential in the construction industry. Potential construction applications for RFID technology discussed here include concrete processing and handling, cost coding for labor and equipment, and materials control. Conceptual design systems for these applications are also considered and developed. Discussion of limitations of RFID technology for construction applications include proximity of equipment, nearby metallic objects, costs, and workforce attitudes. Conclusions are drawn regarding possible future impacts on construction industry.
