Domestic construction industry has considerable level of construction performance and technology thanks to the economic development and as the result of performing diverse oversea construction project. However, construction disasters have been steadily increasing, and do severe disasters at faster pace. Most of such disasters happen at small and small medium-sized construction fields, which contract size is less than 10 billion won. small and medium-sized construction fields are not obliged to designate a safety manager, and have limitations in engaging self-regulating disaster prevention activities due to reduced budget for safety facilities. For the small and medium-sized construction sites with less than 10 billion won, the Ministry of Labor has been carrying out mobile inspections of construction safety. However, the effect so far is insignificant and an improvement plan is required. Therefore, in the present thesis, we derive problems appearing in the current construction safety mobile inspection system, investigate and study systems in foreign countries, and suggest an efficient and effective plan to operate safety technology inspections. First of all, we establish a standard to select sites to be inspected that are high in construction risk and disaster occurrence probability In addition, we suggest a plan to take administrative and judiciary measures based on the total score for disaster factors considering the disaster occurrence probability and the illegal practices. Furthermore, a scheme to maximize the effect of disaster prevention is sought by building an organic cooperative system between the Ministry of Labor, Korea Occupational Safety ＆ Health Agency and other organizations specialized in instruction of construction disaster prevention. Finally, we induce a research conclusion that leads to self-regulating safety management through checking and instructing systematic management on mobile inspections.

Water is a strategic resource for Singapore due to its small land mass and more than half of the mainland serves as catchment for raw water, including construction sites. Construction site typically involves earthworks and in conjunction with the frequent and intense rainstorm in Singapore, produce runoff of high turbidity due to suspended sediments. The resulting high concentration of suspended sediment in construction site runoff very often leads to aesthetically unpleasant reservoirs and potentially increases the treatment cost of raw water. To mitigate this, the local standard requires the discharged concentration of total suspended solids of construction runoff leaving a construction site to be less than 50mg/l which is a very high standard. This paper will present, examine and discuss particular issues and practices of Singapore's construction industry in meeting this requirement. The focus will be on two areas: Government lead initiatives and industry practices. How the government agencies worked together with the industry professionals to develop a system to ensure meeting of the standard is discussed. In addition, the types of industry practices, including various Best Management Practice to reduce erosion in construction sites and implement effective sedimentation on construction sites are examined.

소규모 공사는 건축에 있어 가장 기초적이며 근본이 되는 의미를 가진다. 현재 $\ulcorner$건축법$\lrcorner$ 제8조(건축허가)에는 도시계획구역 이외의 지역에 대하여 연면적 $200m^{2}$ 이상이거나 3층 이상인 건축물에는 공사현장에 감리원을 배치하도록 명시하고 있으며 이러한 기준 이하의 건축물에 관해서는 건축신고로 이루어지고 있다. 하지만, 법의 범위를 벗어난 공사현장에서 많은 문제점이 발생하고 있다. 건물의 설계는 전문가인 건축사가 하지 않으며 별도의 감리자도 없이 지역담당 공무원의 현장 방문으로만 관리하고 있는 실정이다. 현장의 기술력은 1980년대의 그것과 크게 다르지 않고, 노동자들의 안전은 더욱 문제가 되고 있으며, 또한 자재선택이 적절치 못해 건축물의 전체적인 품질저하를 초래하기도 한다. 따라서 본 연구에서는 소규모 프로젝트에 대한 현행 법규를 검토하고 소규모 공사현장 책임자와의 설문 및 인터뷰조사를 통하여 현장관리실태를 파악하고 문제점을 분석한다. 그리고 문제점에 대해 많은 현장을 경험한 고령의 기술자를 적극 활용하기 위해 Data Base를 구축하고 온라인 및 오프라인을 통해 공사를 조언 및 관리하는 방안을 제시하는 것을 목적으로 한다.

The purpose of this study is to reduce the accident rate by introducing a safety system for small construction sites belonging to local governments. In the case of a small construction site, permission is granted through the building permission department and the construction management of the building safety management of 1,000 square meters of floor area less than 3 stories is not properly performed in the Enforcement Decree of the Building Act of Korea. In the current state of industrial accidents in 2016, 81.8% of all accident victims are found to be vulnerable to accident such as those occurring at work places with less than 50 employees. Considering the fact that the construction work with less than 5 billion KRW of the construction cost in Korea generates the most deaths, it is time to introduce the safety and health system of local governments.

인적 및 물적 피해를 크게 초래하는 건설현장의 안전사고를 효과적으로 방지할 수 있는 시스템이 절실히 필요하다. 건설현장의 안전관리 시스템은 주로 대규모 건설현장 위주로 시범 운용되고 있으나, 중소규모의 현장에서 저비용으로 운용할 수 있는 안전관리 시스템은 많이 부족한 실정이다. 건설현장의 안전사고는 예상되는 위험 지역에 허가받지 않은 작업자가 접근하지 못하도록 사전 조치를 하면 효과적으로 방지할 수 있다. 본 연구에서는 소규모 건설현장에서 저비용으로 운용할 수 있는 사물인터넷 기반의 위험구역 경보 시스템을 개발하였다. 본 시스템은 지그비 기반의 비콘기술과 셀룰러 이동통신 기술 등을 활용하여 건설현장에서 추가적인 네트워크의 구축이 없이 허가된 작업자 또는 외부인이 위험구역에 접근시에 감지하고, 안전 관리자에게 위험 경보를 즉시 통보하여 적절한 안전조치를 취할 수 있다.

As shown in the accident analysis from 2007, it has been found that causes of accidents on large-scale projects are different from those found in general construction projects. A 300-question survey regarding systematic and practical aspects of safety problems at construction sites was distributed to ten (10) different companies. Participants were to respond subjectively, so that the results could be used to assemble the first formal questionnaire survey. They were collected and compiled by an advisory committee for this study. The resulting surveys were then sent to the division chiefs of the top 100 construction companies in Korea, in order to improve the response rate. The Department of Safety & Health Direction, and the :Ministry of Labor, ROK sent the same sheets to medium and small construction companies that placed within 101-200th of all Korea construction companies. The above safety engineers were classified into four (4) levels, from 1st to 4th, followed by the project dollar amount and risk level. Formulae were developed to assign safety engineers to construction sites by engineer level, the project dollar amount, and the project risk level. Conclusions are summarized as follows: 1) Reviewing the assignment system of experienced safety engineers to large scaled projects - The more experienced the engineers assigned to a project, the higher the level of accident prevention. 2) Enforcing the assignment of advanced level safety engineers to large-scaled sites - At least one advanced-level safety engineer should be assigned to construction sites with projects valued at $15million USD (15,000,000,000). 3) For assigning safety engineers by risk level - Twenty models have been developed to calculate the number of safety engineers to be assigned by risk level. In the future, risk level for each job should be established by the government (as is now the practice in Germany).

정부의 중·소형 민간공사장 안전관리 강화대책 발표에 따라 CCTV 설치 의무화 대상이 대형 공사장에서 중·소형 공사장으로 확대되었다. 하지만 기존의 건설현장의 CCTV는 안전관리를 위한 단순 관제용으로 활용되고 있어 건설현장의 모니터링을 위한 연구가 필요하다. 이에 본 연구에서는 단안 카메라를 이용하여 촬영한 단 영상을 기반으로 3개의 소실점(vanishing point)을 계산한 후 내부표정요소 정보를 포함하고 있는 카메라 행렬을 결정하고 기준 객체의 높이를 통해 대상 객체의 높이를 계산하여 정확도를 검증하는 연구를 수행하였다. 단안 카메라 기반의 소실점을 이용한 높이 결정 실험을 통해 별도의 지상기준점 측량 없이 단 영상만으로 대상 객체의 높이를 결정할 수 있었으며, 정확도를 평가한 결과 평균제곱근오차는 ±0.161m로 나타났다. 따라서, 단안 카메라를 이용하여 촬영한 단영상을 통해 건설현장의 공사 진척도를 모니터링할 수 있을 것으로 판단된다.
