RFID in Construction for Component and Sub-Assembly Tracking ...

From BFRL: Construction Metrology and Automation Group ...

... "the Construction Metrology and Automation group developed a prototype system of integrated hardware and software to measure the position and orientation of steel frame components and sub-assemblies at the job site and to allow for web-based interactive information entry and query while at a component's location. This prototype implementation is a web-based system for rapid tracking of construction components with compact, field-rugged sensors and computers, interoperability protocols for data transmission, and 3D site simulators that reflect the instant state of tracked components on the construction site. The approach involves the use of RFID and bar code identification systems, 3D long range coordinate measurement technologies, local data processing, wireless communications, high speed networking, temporal project databases, web-based data analysis, and 3D user interfaces to provide real-time access to part status updates at the jobsite. In FY99, we demonstrated 3D spatial tracking of discrete components in real-time to viewers at a remote location over a km away under highly controlled conditions. " ...
