According to the statistics publication of KOSHA, more than half of serious accidents at the construction sites were related to the temporary works and/or the temporary structures such as scaffoldings, shores, earth retaining walls, etc. The structural failures are occurred because of the overload acting on the structures or lack of performance of the one or more members of the structures. For the prevention of the collapse accidents relating to the temporary structures at the construction sites, we have to control construction processes not to occur the overload and also to control the performance and quality of each member of the temporary structures. MOLIT has amended the ｢Construction Technology Promotion Act｣ on Jan. 7th, 2015 to ensure the structural safety of the temporary structures. According to the Act, the designers of the construction design projects should check the structural integrity of the structures including the temporary structures and the construction companies have to let ‘the Relative Professionals’ confirm the structural integrity of temporary structures, the shores(≥ 5 m high) and the scaffolds(≥ 31 m high), before construction. Also, MOLIT has amended the ｢Regulation for Construction Technology Promotion Act｣ on Jul. 4th, 2016 for quality management and testing of temporary equipments. According th this regulation, the construction companies and supervisors should manage and test the temporary equipments before using them. In this paper, the standard drawings of the shores(< 5 m high) and the scaffolds(< 31 m high) and the amended ｢Business Guideline for Quality Management of Construction Work｣ are presented. As the result of this study, MOLIT noticed the amended “Business Guideline for Quality Management of Construction Work” on Jul. 1st, 2017.
