To improve the monitoring, statistics and anti-theft management level of the valuable materials in the construction site, the new location technology for valuable materials on construction site based on the ultra-wideband radio frequency technology (UWB) is adopted in addition to traditional approach of people-oriented management. Based on positioning tests under the static closed and dynamic open environment separately, two construction site layout methods are put forward using UWB signal receiver and tag transmitter, which are suggested in practice. It is better to choose UWB positioning as main technique in the static closed environment, while manual as main management in the dynamic open environment.
