Application of USAN Technology for Monitoring Temporary Construction

Temporary structure is prone to construction accident due to the dynamics in construction. Any unexpected adversary effect can cause construction failure in temporary structures. Therefore, the structure should be continuously monitored to understand its behavior during construction. The objective of this study is to test the feasibility of the ubiquitous sensor network (USN) technology in collecting construction data during the construction operation of temporary structures. This study presents the research result at the Construction System Integration Laboratory (CSIL) at the Pusan National University. In the study, various sensors were integrated into the USN to collect data of a temporary structure in a concrete operation. Using a monitoring system, the structure was monitored to find out whether any excessive structural behavior occurred. The data were used to provide a warning signal for evaluation as well as repair.
