  • 현재까지의 건설 안전관리와 리스크에 관한 연구들은 건설현장 내부(근로자)에 한정되어 있어 건설현장 외부(제 3자)에 대한 연구는 미비한 실정이다. 그 결과, 건설현장 주변의 일반인들이 피해를 받고 있으며 산재 다발이라는 부정적인 이미지로 언론이나 일반 대중들에게 투영되고 있다. 일반 대중들에게 부정적인 이미지를 탈피하기 위해서는 건설현장 내부(공종, 건축물)에만 집중되어있는 기존의 안전관리가 아닌 건설 현장 외부(제 3자)에 대해서도 고려된 종합적 안전관리체계를 구축해야 한다. 이에 본 연구에서는 건설 현장 외부(제 3자)의 인명사고 리스크를 정량화하고 몬테카를로 시뮬레이션을 활용하여 리스크가 어떻게 변화할 것인지 예측하고자 한다. 이를 위하여 첫째, 선행연구를 고찰하여 불안전한 상태와 인명사고 발생형태를 정의한다. 둘째, 14년 간 건설현장 외부에서 발생한 제 3자 인명 손해배상액 데이터를 수집한다. 셋째, 수집된 데이터의 사고내용을 분석하여 사고 발생분석 모델을 설정한다. 넷째, 리스크 정량화 모델을 구축하고 불안전한 상태, 인명사고 발생형태별 사고발생확률과 손해배상액 확률분포를 제시한다. 마지막으로 몬테카를로 시뮬레이션을 통해 도출된 사고 형태별 분포결과를 분석한다. 본 연구의 결과는 향후 건설현장 내 외부 안전관리 체크리스트 개발 및 인명사고 예측 관리 시스템 개발의 참고 자료로 활용될 것으로 기대된다.

  • Accident analysis models were developed to improve the construction site safety and case studies was conducted. In 2016, 86% of fatality accidents occurred due to simple unsafe acts. Structure related accidents are less frequent than the non structure related causes, but the number of casualties per accident is two times higher than non structure one. In the view of risk perception, efforts should be given to reduce accidents caused by low frequency - high consequence structure related causes. In case of structure related accident, structural safety inspection and management (including quality), ground condition management / inspection technology, and provision of risk information delivery system in case of non structure related accident were proposed as a solution. In analysis of relationship between safety related stakeholder, the main problem were the lack of knowledge of controller and player, loss of control due to duplicated controls, lack of communication system of risk information, and relative position error of controller and player.

  • 우리나라 건설공사의 품질관리체계는 관련법에 근거한 규정의 조합과 시공자가 구축한 ISO/KS A 9001에 의한 품질경영 시스템의 운용에 의한 방법의 혼합형이다. 이 두 가지의 품질확보체계는 상호 보완적이며 통합된 체계로 운영되어야 하나, 시공자의 품질경영시스템을 활용하지 못하고 법에서 정한 기준과 방법, 절차 등의 규정에 따라 모든 공사에 있어서 일상화된 품질관리업무가 수행되고 있다. 이러한 현상은 ISO규격이 도입된 이래 지난 10여 년간 계속된 문제점으로 개선이 요구되고 있다. 품질관리의 철저를 목표로 고객 만족을 위한 예방적 품질관리사고를 정착하는 일은 건설산업의 당면과제이다. 이에 본 논문에서는 건설현장 의 실무자를 대상으로 품질관리 관련 의식에 관한 설문조사를 실시하였으며 그 결과를 토대로 건설공사 품질관리 체계의 운용에 대한 만족도를 정리하고, 나아가 향후의 개선방안에 대한 논점을 제시하고자 한다.

  • While institutional matters such as improvement on Basic Guidelines for Construction Safety are greatly concerned to reduce falling accidents at construction sites, there are short of studies on how to practically predict accident signs at construction sites and to preemptively prevent them. As one of existing accident prevention methods, it was attempted to build the early warning system based on standardized accident scenarios to control the situations. However, the investment cost was too high depending on the site situation, and it did not help construction workers directly since it was developed to mainly provide support operational work support to safety managers. In the long run, it would be possible to develop the augmented reality based accident prevention method from the worker perspective by extracting product information from BIM, visually rendering it along with site installation materials term and comparing it with the site situation. However, to make this method effective, the BIM model should be implemented first and the technology that can promptly process site situations should be introduced. Accordingly, it is necessary to identify risk signs through lightweight image processing to promptly respond only with currently available resources. In this study, it was intended to propose the system concept that identified potential risk factors of falling accidents by histogram equalization, which was known as the fastest image processing method presently, used visual words, which could enhance model classification by wording image records, to determine the risk factors and notified them to the work manager.

  • The better industry develops, the more spaces need but in the limited area. Most building become larger and more complicated if the more spaces need in the constant area. And this leads to do underground work in long period generally six(6) months for 6 basement stories due to the selection of TOP DOWN technique. Working environment in this underground area can be problems and should not be overlooked, because air quality in underground spaces become quickly worse. Recently, department name to control construction safety has been changed to ENVIRONMENT & SAFETY TEAM from SAFETY TEAM. This means that it is very important to control against environmental condition at site so much. Overall construction work as well as underground work should conform to the requirement of working environment, particularly against inhabitants around the construction area. Strut protection, one of earth protection method, in case to 40m long strut may become weaker due to thermal stress or its longitudinally compressive strain and the another one, earth anchor protection may not be applied to the site In case of encroaching on vertical underground borderline because of regulation to prohibit it. It is necessary that TOP DOWN technique should be introduced in order to solve the external and internal problem of the site such as difficulty level of the work, potential danger with excavating depth, and shortening workperiod. It is needed that improving way of working condition should be shown and simplified computer simulation program should be also provided for checking pollution level & ventilation, excluding of lighting problem here. Results measured with conformance to the Regulation for Working Environment Measurement, enforced by Ministry of Labor have been applied to the computer program developed here. Sample air taken at unit workplace which was considered as exposing condition of pollutant at breathing point and within a range of behavior of the workers, Identified exposing group in underground work, using Moded Flow Life Finally, three types of ventilation system, type I with blower & ventilator, type II natural supply with mechanical ventilation system, and type I mechanical ventilation with Drivent Fan Unit System are selected for this study.

  • Efforts to reduce on-site safety incidents have expanded, leading to active research in this domain. However, a systematic analysis to improve the utility of technology is lacking. In this study, we conducted a survey on the various institutional and technical improvement measures to promote the application of smart construction safety technology over three years after the implementation of the "Smart Safety Equipment Support Project." The results showed that financial constraint was the primary obstacle in the adoption of this innovation. Fostering a flexible environment in the utilization of management fees and financial support of projects was determined to aid in the extensive application of the technology. Ensuring cost efficiency and user-friendliness were principally necessary for technical enhancements in the smart construction safety technology. Technologies, such as VR/AR safety education, real-time location tracking, wearable devices, and innovation on streamlining safety-related work efficiency, had been anticipated to contribute to on-site safety. Operating a smart safety control center was expected to be beneficial in the systematic securing of data and reduction of safety blind spots. Effective methods had been suggested to overcome the barriers that hindered the development and application of smart construction safety technology. This study facilitates in the technological improvements in this field.

  • This paper presents the findings obtained from the investigation of fatal disasters occurred by small-sized construction firms which have been accepted as to provide lower safety performance other than large-sized construction enterprises and cause more than half of the safety accidents in average. The study identifies the current status of safety performance provided by the small-sized construction contractors in details, find the issues involved with lack of safety performance, and suggest the improvement measures derived from the findings. A survey questionnaire was administered to the construction contractors, which are listed in the database of Construction Association of Korea as to fall into rank between 501st and 1000th in construction capacity. Safety issues such as the performance of safety management system, safety control structure, safety cost relative to safety control, education devoted to safety improvement, usage of safety garments or individual protective tools, and activities to maintain safety performance on site, etc were investigated from the study.
