This study analyzed the safety management efficiency through input-oriented BCC Model using DEA by making of Models, in which this study selected the number of staff affiliated with the construction site, number of staff members on the construction team, and number of safety personnel as Input Factor, along with the number of disaster victims and zero-accident accomplished hours as output elements, targeting 40-or-so apartment building construction sites which are being built by 3 domestic construction companies. As a result of efficiency, it was 0.643, the number of efficient DMU was 4. In the aspect of returns to scale, 21 construction sites(52.5%) found to be in a state of increasing returns while 14 construction sites(35%) was in a state of Decreasing returns. The reason for inefficiency was found to lie in technical factors in case of 30 construction sites(75%). Lastly, inefficient DMU is in need of 38.9 % and 66% reduction in site personnel and safety personnel. Based on study results, the 29 construction sites accounting for 72.5% of DMU for safety management efficiency evaluation object turned out to do inefficient safety management that doesn't fit the size of each company.

Recently, there has been constituted the government regulations and the normative methods to control the safety management activities in construction fields, but almost of these regulations are ineffective, because of some characteristics safety management have. The needs of the times make government regulations and the normative methods change to autonomic management methods. In this context, it is significant certainly to improve the standard of safety management that is used as a tool to protect the workers from the accidents or industrial disasters in the construction field. In this research, it will be showed that the outside regulations and safety management systems of the head office have their limits to reflect the safety managements of field participants. Then, it will be presented the improved model of self-control safety management activities which is essential for success safety management.

Construction work has potential risk factors in the process. Therefore, the safety management task is very important and requires continuous management. In particular, the importance of safety management in construction projects has been highlighted recently with the introduction of the act on punishment of serious disasters. In this perspective, this study intends to select and present high-risk construction types that requires safety management. The presented result is expected to present standards for systematically performing safety management of construction projects.

This paper presents the safety performance of Korean domestic construction companies including the characteristic and current status of safety management actions of the firms. Safety performance both at the head office and job sites of each construction companies, which are divided four groups by construction capacity ranking, are investigated. General recognition that there is a wide difference of safety performance among domestic construction companies by construction capacity ranking was confirmed by comparing the safety performance at the head office and the job sites of the companies under the study. Data analysis shows that the safety performance of the group I and II has the largest difference, and this difference of the group II and III and group III and IV are gradually decreased, respectively. This paper presents the safety performance improvement measures, which is applicable to safety management components consisting of both the head office and job sites safety management systems of each group (e.g., I, II, III and IV) suffering the lack of safety performance.

After the IMF financial crisis, a lot of risks in construction industry have been increased gradually with the expansion of construction industry widely, higher stories of building, and the expansion of the underground space and excavation work. These risks are bringing out construction accidents such as the death, the injury of worker and so on, not so much as it would be effected the corporation's image. In spite of these situations, many construction industries still maintain the wrong methods and not try to decrease construction accidents. Recently, we should focus on the fact that management system of the larger construction also is being good, on the other hand, the condition of the work in the case of smaller construction industries is very poor, construction company have a particular safety management system but it has a difference according to the construction magnitude, construction companies have a particular safety management system but it has a difference depending on the construction according to the construction magnitude. Therefore, this study will suggest the developed way of construction safety management by the comparison and analysis from the difference between the higher and the smaller construction industries.

In modular construction, safety management is required to prevent the occurrence of risk factors such as lifting work and high place work due to the characteristics of the construction method. Therefore, this study is a basic study for safety management of modular construction, and the purpose of this study is to compare and analyze the classification system of modular construction derived by analyzing the construction process of the existing case. Based on the results of this study, the safety management classification system will be used in future research to derive safety management factors in modular construction.

In order to reduce the risk of accidents, we proposed a construction safety management system combined with wearable device and LoRa (Low-Range Wireless Network) communication method to apply the usefulness of Internet (IoT) technology which means "everything connected". to construction safety management Management system. The proposed wearable safety device is a device that relays information exchange between wearable safety device and safety management server by LoRa wireless communication method. The safety management server can store workers bio-data and perform big data analysis. If a risk factor is determined from the analysis result, a warning is sent to the wearable safety device and the manager's application. The goal of this system is to prevent construction workers from entering the dangerous area that is not suitable for work, and to prevent safety accidents caused by human cause by detecting abnormal condition during work.

Construction Management(CM) system, which was introduced some years ago to large national construction projects, such as the construction of Incheon New Airport, construction of high-speed railroad and World Cup stadiums, is considered to be still in its early stage and safety at each step of CM is very poorly controlled. In an attempt to improve such inferior safety management of domestic CM, this study made comparative analysis about operation system of safety management with CM system in domestic and abroad. Also suggested the model under consideration with CM, which is suitable for the situation of Korea.

Construction workers are engaged in many activities that may expose them to serious hazards, such as falling, unguarded machinery, or being struck by heavy construction equipment. Despite extensive research in building information modeling (BIM) for safety management, current approaches, detecting safety issues after design completion, may limit the opportunities to prevent predictable and potential accidents when decisions of building materials and systems are made. In this respect, this research proposes a proactive approach to detecting safety issues from the early design phase. This research aims to explore accident precursors and integrate them into BIM for tracking safety hazards during the design development process. Accident precursors can be identified from construction incident reports published by OSHA using a text mining technique. Through BIM-integrated accident precursors, construction safety hazards can be identified during the design phase. The results will contribute to supporting a successful transition from the design stage to the construction stage that considers a safe construction workplace. This will advance the body of knowledge about construction safety management by elucidating a hypothesis that safety hazards can be detected during the design phase involving decisions about materials, building elements, and equipment. In addition, the proactive approach will help the Architecture, Engineering and Construction (AEC) industry eliminate occupational safety hazards before near-miss situations appear on construction sites.
