The Analysis of the Current Situation in Design Change of Temporary Structures

The construction accidents in temporary structures have ceaselessly happened and these mostly lead to serious disasters associated with public criticism. Recently, the accidents under construction due to incomplete or faulty design has repeatedly occurred such as the overturned girder accident in Jangnam Bridge, the submerged incident in Noryangjin and the slab collapse in Banghwa Bridge. In order to prevent such accidents due to the faulty design in temporary structures, it's important to set up the solid construction management system which allows the reasonable design change if necessary. In this regard, this study provides the basic data for the reasonable design change in temporary structures by conducting a question investigation to the construction, design, and supervising companies. From the survey results, the kind and range of the temporary structures which should considers the design change were suggested by the deduced reasonable processes.
