Using the CSI(Construction Safety Management Integrated Information) data, a comparative analysis was conducted by work type and construction cost according to whether the construction sites were subject to making a safety management plan or not. As a result, by type of work, the ratio of deaths in non-plan sites was high in mechanical facilities and earthworks, and the operation performance of the system was much higher in sites that were less than 5 billion won of construction cost.

There are many accident causes related to even an accident. As well four(4) stepped causes of one accident at construction sites are analyzed in the study. First, eleven(11) cause factors are set up at each step such as policy level, management, indirect, direct level which are discussed and determined by field experts with 15year experience or more. Therefore, one direct cause occurred in construction site can be connected to the previous cause than in direct and management, and policy problem of previous management. These questionnaires results are analyzed with three different methods such as weighing level by Delphi technique, correlation analysis, critical pass method. Three different methods show their characteristic to see which subcontract work is more dangerous or not. Subcontract or at a construction site can be use the above three different cases as they need at their site in order to make more effective countermeasures.

The purpose of the safety management plan under the Construction Technology Promotion Act is to improve the quality and safety of construction engineers during construction work. To prevent a collapse accident of a facility after completion by preventing a collapse accident of gravel, an earthwork, a river structure or the like. In order to prevent collapses, the purpose of the project is to study measures to improve the ability of construction technology promotion law to ensure the quality of construction materials at the time of construction work.

The construction accidents which had been on the downward trend for the past decades have increased for five consecutive years since 2008. In order to let the increasing trend of construction accident slow growing or switching to decline, various efforts are required of all members in construction industry such as government, employers, construction engineers, safety managers, construction workers, etc. Although the criteria for appointment of safety managers in construction site introduced in 1982 have contributed to prevent construction accident as a forefront for the past 30 years, it has not been a remarkable improvement in the safety manager's status and roles which have been required to change according to the changes of circumstances and environments. In associated with a newly introduced the criteria for appointment of health managers in construction site in the year 2015, the problems such as role, status, number of safety and health managers are needed to be considered comprehensively and improved widely. In this study, we propose several improvement plans which will improve the current criteria for appointment of safety and health managers in construction sites.

According to the analysis report of construction fall accident, situation not installed safety facilities caused the largest of disaster in temporary structure. Therefore, actionable measures will be needed identifying the installation of safety facilities immediately. In this study proposed plan by the safety facilities to effectively visualize, supervision can be easily for reduce fall accident. This system can be used BIM and augmented reality technology by combining in the field in real-time. Through this study, safety facilities management is improved and expected to prevent a accident.

In this paper, the systematic problems of safety management in domestic construction industry are presented by the investigation and analysis of construction fatal injuries. In particular, it is discussed that the current construction safety management system by contractors leading is ineffective to prevent the serious accidents caused by inappropriate planning and design and to circulate the safety management cycle without interruption. A couple of ways for improving domestic construction safety management system are suggested in broad perspective. This is done by the analysis of construction safety management system of four advanced industrial countries such as the United States, the United Kingdom, Germany, and Japan and the study of a best practice. Total safety management system by owners leading is recommended to prevent construction accident effectively because this system makes all the parties join to the management system and distribute the responsibilities clearly to each party. This will drop the accident occurrence rate by dragging all the parties' cooperations and activating the total safety management system in an early stage.

Compared to other industries the construction industry experiences more casualties and property damage due to safety accidents. One of the reasons is the increasing number of foreign workers. For this reason, past studies have found that foreign workers at construction sites are more exposed to safety accidents than non-foreign workers. Nevertheless the proportion of foreign workers involved in safety accidents at construction sites is increasing, and there has been a lack of research to predict the risk of safety accidents at construction sites. Additionally, realistic safety management is lacking due to a lack of safety accident risk prediction research. Therefore, in this study, we would like to propose basic research that proposes an AI-based safety accident prediction model framework for predicting safety accidents of foreign workers at construction sites. The framework and results of this study will contribute to reducing and preventing the risk of safety accidents for foreign workers through risk prediction for safety management of foreign workers at construction sites.

The purpose of this study is to verify the effect of the converted accident ratio on the contract of construction work. For doing the objective, this research analyzed the bid system and the converted accident ratio computation system in force. Additionally, we estimated what risk grades influence a successful bid of constuctin work. As a result of this study, we have recognized that the converted accident ratio scarcely has an effect on PQ process.

In construction work, it can be difficult to know the exact number of full-time workers, so the accident rate is calculated using the approximate number of full-time workers. In addition, as the accident rate calculation is performed based on the assumption that the number of accidents is proportional to the approximate number of workers, the reliability of the calculation result may be questionable. This study proposed a new indicator for accident level based on the progress payment and the number of injuries. The accident-progress ratio, which can be calculated by simply dividing the number of injuries by progress payment, can replace the existing accident rate index or be used as an auxiliary indicator of the accident level. The correlation coefficient between the number of injuries and the progress payment was higher than that between the number of injuries and the number of construction workers. In addition, over the past 10 years, the accident rate has been increasing, whereas the accident-progress ratio has showed a decreasing tendency. This might leave room for different interpretations of the annual variation in the accident level in the construction industry.

As contemporary building construction type is getting higher and deeper, construction equipment usage is getting more, and related fatal accidents are on an increasing trend. Because of this, a method was drawn which could grasp the present state of construction equipment management and manage safety of the equipment more easily for accident prevention by choosing 2 kinds of Construction equipment which cause safety accident frequently among the equipment mainly used in construction site. This study suggested a method about construction equipment safety management using "smart phone" base which could be used in safety management for construction equipment by whomever in construction site. After attachment of QR code included safety checklist, It became possible that site managers could check more efficiently by scanning with their smart phone when they inspect equipment. Moreover, by the construction interested who didn't know what and how they have to inspect could point out unsafe condition in the early stage of equipment entering or take unsafe one out of the site by using new smart phone safety checking system is installed, it became possible that critical accident caused by construction equipment was prevented in advance.
