건설 산업은 전체산업분야들 중에서 가장 많은 재해사망자를 발생시키는 산업분야이다. 국내 건설업의 사고부상자는 중소규모 사업장에서 거의 대부분 발생한다. 또한 전체 공종 중 거푸집 공사에서 가장 많은 재해자가 발생하고 있다. 상대적으로 재해에 취약한 중소규모 건설현장의 거푸집 공사에 대하여 안전점검사항을 제시하고 어떤 항목을 중점적으로 관리해야하는지에 대한 의사결정을 지원할 수 있는 연구가 시급하다. 따라서 본 연구에서는 안전의식이 상대적으로 낮은 중소규모 사업장에 대하여 국내 건설현장의 안전사고 중 가장 많은 재해가 발생하는 거푸집 공사의 위험요소에 대한 점검사항을 명확히 제시하고 중점적으로 안전관리를 할 수 있는 체크리스트를 제안하였다. 연구 방법은 국내 건설현장에서 발생했던 재해 사례 70,618건을 분석하여 위험요인 및 사고 예방 대책을 도출하였다. 도출된 점검 항목을 안전관리전문가 5명에게 검토 받은 후 현장에 직접 적용함으로써 현장에서의 활용 가능성을 확인하였다. 연구의 결과는 실제로 발생했던 재해의 위험 요인을 도출하여 만든 체크리스트이기 때문에 현장의 작업자들에게 잘못된 점을 명확히 지시하여 시정하는 것이 가능했다. 본 연구의 결과가 중소규모 건설현장에 대한 효율적인 안전관리를 수행하고 재해율을 감소시키는데 기여할 수 있기를 기대한다.

The environmental management is essential for construction projects. The environmental management cost for construction projects is used for various purposes to control the environmental pollution and treat the wastes generated from the construction sites. Six construction cases were analyzed to compare the environmental management cost. The proportion of environmental management cost for total construction budget should be higher than 0.70% in redevelopment projects and 0.30% in newly constructed buildings, respectively, but every six construction cases did not meet the legal requirement. Redevelopment projects expanded more environmental management cost than the newly constructed projects especially in noise control and wastes treatment. In case of apartment construction projects, the proportion of environmental management cost of redevelopment buildings is 2.4 times higher than the newly constructed buildings, but in all cases, paid more attention to the noise and waste controlling measures than the wastewater treatment. It is needed to ensure the cost-effectiveness of environmental management for achieving the eco-friendly construction sites.

Due to the aging of economically active population in the world, the average age of workers in the domestic construction industry is also steadily increasing. This study analyzes the aging of construction workers in small-size construction sites in Busan, where the aging of the economically active population is the most severe in Korea. As a result of the study on the aging of construction workers in six construction sites with a construction cost of less than 500 million won in Busan, it was found that 65% of the workers were over 50 years of age. In addition, several experts interviews and survey revealed that 'securing welfare facilities for construction workers' and 'diminishing prejudice about the construction industry" were the most urgent and effective methods to overcome the aging problems. The results of this study can be served as basic data to solve the aging problems in the industry.

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.

The purpose of this study is to determine whether the variables of the agency factors affected the number of occupational fatalities in the construction industry in order to determine whether there is a relationship between the number of occupational fatalities occurring at the construction sites and the agency. The considered agencies are KOSHA (Korea Occupational Safety and Health Agency) and MOEL (Ministry of Employment and Labor). The variables of two agency factors are classified as follows: the variables of two agency factors are the number of employees, budget amounts, technical support and guidance for construction sites of KOSHA, and the number of labor inspectors, the number of inspection and oversight workplace, the number of criminally punished construction sites and fines levied on them in the industrial accident prevention departments of Regional Employment and Labor Office. The multiple regression analysis was conducted to determine the effect of two agency factors on the total number of occupational fatalities in the construction industry. The policy implications derived from this study are that, in order to reduce the fatalities of construction sites by KOSHA, the appropriate level of increased budget for KOSHA must be secured every year. In addition, the amount of fines levied on construction sites by the labor inspector in the industrial accident prevention departments of Regional Employment and Labor Office reduces the occupational fatalities at the construction sites.

The number of industrial accident victims in the construction industry accounts for 1/3 of those in the entire industries and about 30% of the total compensation costs are spent in the construction industry. As such, the construction industry is a typical industry causing numerous safety accidents. This study analyzes the status of industrial accidents in small scale construction sites to build maximum five-story buildings by examining statistical data for the past five years, investigating those construction sites and conducting interviews with the workers. This study also seeks the causes of and measures for industrial accidents in the small scale construction industry through comparison with relevant systems. The findings are as follows: (1) To reduce hazard rate, shaping the working environment and safety measures that take into account the physically weak classes of the middle aged and the aging are urgently required, because 62.9% of the industrial accidents in the construction industry occurred to those who are 50 years of age or older. (2) The hazard rate at small scale construction sites with less than 10 construction workers accounts for 55% of that of the entire industries. The government, in this context, needs to support finance or technology and improve system by selecting the small scale construction sites, where industrial accidents occur frequently. (3) Because the hazard rate of unskilled workers with less than 6 months of work experience accounts for 90.95% of the total, safety education needs to be concentrated on those unskilled workers. (4) The relevant standards need to be segmented and revised and bolstered, given that 64.79% of death disaster in the construction industry occurs in the temporary structures including scaffolds and ladders.

The Case Study prepared by PCPA and Lift Group will identify a growing development problem in urban areas; high value project sites that are restrictive in size or "tight" are underutilized and underdeveloped. In an effort to remedy this problem, our team will evaluate a design program through the lens of both conventional construction and Core Cantilever Construction. It is also important to differentiate between Core Cantilever construction and the plagued "Lift Slab" construction method as they may be confused, due to the top down construction sequence. This article will demonstrate that constraints inherent to conventional construction techniques prohibit economically viable development of these project sites, while Core Cantilever construction methods increase the projects value by reducing construction timelines and increasing the useable floor area.

The construction industry has the highest occupational fatality and injury rates related to accidents of any industry. Accordingly, safety managers closely monitor to prevent accidents in real-time by installing surveillance cameras at construction sites. However, due to human cognitive ability limitations, it is impossible to monitor many videos simultaneously, and the fatigue of the person monitoring surveillance cameras is also very high. Thus, to help safety managers monitor work and reduce the occupational accident rate, a study on object recognition in construction sites was conducted through surveillance cameras. In this study, we applied to the instance segmentation to identify the classification and location of objects and extract the size and shape of objects in construction sites. This research considers ways in which deep learning-based computer vision technology can be applied to safety management on a construction site.

Current fire safety in the construction sites has developed piecemeal over a considerable period of time. However, the law and regulation of fire safety is insufficient to protect fro in the construction sites. The frequency of fire in the construction sites is very rare but it brings longterm deterioration durability of building structure and large scale industrial calamity. There are many process of works and each work deals with many kind of flammable material, so it is very difficult to find a proper safety fire prevention. This study executed the questionnaire and fire experiment of the welding work to provide effective fire prevention counterplan.
