  • Risk Assessment to list possible safety disasters and their probability and severity is the starting point for effective safety management on construction project site. However, the safety managers in owners, construction supervisors, contractors, and sub-contractors still have difficulties in judging the priorities of safety activities and preparing responses to each potential safety disasters. Therefore, this study aimed to suggest a systematic method in assessing safety risk prior to commencement with the agreement of stakeholders. FMECA(failure mode effects and criticality analysis) was selected as a main assessment tool and it was modified according to the characteristics of construction projects and trades. Each risk is, firstly, evaluated with occurrence probability, possible loss and impacts to projects, and detections, and then risk priority number(RPN) is calculated. Subsequently, the managers of each stakeholder discuss the types, timing, and responsibilities of responses as a group decision-making process.

  • Quality control and safety represent increasingly important concerns for project managers. In the worst case, failures may cause personal injuries or fatalities. Accidents during the construction process can similarly result in personal injuries and large costs. We present the results of a study designed to identify the tools that are most widely used and those that are associated with successful project management in general, and with effective project risk management in particular. The study is based on a questionnaire administered to a sample of project managers from construction enterprises. The response data was analyzed in order to find which tools are more likely to be used in the those organizations that report better project management performance and in those that value the contribution of risk management processes.

  • If the participants in construction site safety management perform their duties in accordance with the provisions of the Industrial Safety and Health Act, the burden on safety managers would be minimal. However, the lack of specific work guidelines for each participating entity and the greater responsibility of the safety and health general manager than the management supervisor have resulted in safety managers' workload being increased due to the problem of management supervisors' neglect of safety management. In this study, we conducted a survey of the safety manager's duties and related documents during the construction project initiation, early stages, ongoing work, and disaster occurrence/investigation, and conducted interviews to improve and enhance the division of duties.

  • A considerable number of construction disasters occur on pathways. Safety management is usually performed on construction sites to prevent accidents in activity areas. This means that the safety management level of hazards on pathways is relatively minimized. Many researchers have noted that hazard identification is fundamental to safety management. Thus, algorithms for helping safety managers to identify hazardous areas are developed using automated data collection technology. These algorithms primarily search for potential hazardous areas by comparing workers' location logs based on a real-time location system and optimal routes based on BIM. Potential hazardous areas are filtered by identified hazardous areas and activity areas. After that, safety managers are provided with information about potential hazardous areas and can establish proper safety countermeasures. This can help to improve safety on construction sites.

  • 국내 시공사의 해외 건설 비중이 증가하면서, 발생하는 리스크로 인한 비용초과는 시공사의 재정 상황에 막대한 영향을 끼친다. 특히, 현지 관리자의 올바른 시공단계의 리스크 인식은 실질적인 관리에 영향을 끼친다. 그러나 실제 사례에서 발생한 리스크 요인의 비용초과 영향도와 현장 관리자의 인식도에는 차이가 있다. 따라서 이 연구는 리스크 관리를 위한 비용초과 대응전략 구축 이전에 해외 건설 시공단계 리스크 요인을 기반으로 실제 사례와 현지관리자의 인식도 비교를 목표로 한다. 우선, 이론고찰을 통해 선별된 리스크 요인을 기반으로 20개 사례에서 발생한 290개의 비용초과 데이터 기반으로 몬테카를로 시뮬레이션을 통해 추가 데이터를 획득한 후, 다중회귀분석으로 얻을 수 있는 표준화계수를 통해 요인별 비용초과 영향도를 구하였다. 또한, 42명의 현지관리자를 대상으로 동일 요인에 대한 인식도 파악을 위해 설문조사 진행 후, SWARA를 활용하여 분석하였다. 두 데이터 비교 결과, '하청업체와의 갈등', '현지 커뮤니티와의 갈등' 등의 갈등 관련 리스크들이 높은 비용초과를 보인다. 그러나 현지관리자들은 이를 낮은 순위로 인식하며, '자재 가격의 변동', '시공 품질 오류' 등에 대해 높은 순위로 인식하고 있었다. 따라서 현지관리자들의 갈등 리스크에 대한 교육과 관심이 필요하다.

  • 최근 세계적인 경기침체로 인하여 많은 산업이 불황을 겪고 있으며, 건설업 또한 많은 어려움을 호소하고 있다. 이러한 경기침체를 극복하기 위해 건설회사들은 경영의 최적화와 관리조직의 슬림화 등을 통한 공사의 효율성과 생산성 향상을 위하여 많은 노력을 기울이고 있다. 특히, 건설프로젝트 수행의 효율성과 생산성은 현장조직과 관리자 개개인의 업무수행능력에 크게 좌우되므로 현장관리 조직 및 관리자의 역량 및 업무수행능력의 향상은 많은 건설회사의 중요한 과제이다. 이에 본 연구는 일반건설업체 현장관리자들의 업무내용을 직무별로 도출하여 각 업무의 중요도 및 업무량과 업무난이도를 분석하고 관리자들의 직무별 업무수행수준 및 업무수행능력에 영향을 미치는 요인을 분석함으로써, 향후 건설공사 수행에 있어 공사의 효율성과 생산성 향상을 위한 개선방향 모색의 기초자료를 제시하였다.

  • During the administration of a construction project, various types of participants are engaged in the project. From the design phase to the maintenance phase, these participants may confront many risks. To avoid these risks, participants should utilize an insurance company or a bond company. The types of risks and liability that a construction manager may face are listed in the construction law or contract. But there are some arguments related to risk transferring and the content of risks. For this reason, construction managers must carefully consider any possible risks in the contract and the construction law. Therefore, for construction managers to deal with risks appropriately, the introduction of a legal requirement to carry professional liability insurance, a defined compensation range for damages, a method of guarantee in the event of defects, a defined compensation claim period for damage, and a method of damage claim were suggested in this study.

  • Two studies were conducted to examine the relationship between self-efficacy beliefs and industrial accidents. In the preliminary study, focus group interviews were conducted with employees working in manufacturing and construction sector, safety managers, and government officials to understand factors that were associated with industrial accidents. Based on interviews, a questionnaire survey was constructed to assess individual factors (such as self-efficacy beliefs, following safety procedures, life-satisfaction, and stress) that were identified as affecting industrial accidents (such as minor and major accident rates). The questionnaire were administered to a total of 917 respondents (542 employees working in the manufacturing and construction sector, 210 safety managers, and 165 government employee officials overseeing government regulations). The result indicated that three subscales of self-efficacy for employees (self-regulation, enlisting social support, and controlling the environment) were negatively correlated with the company's industrial accident rates. Moreover, those employees with higher self-efficacy were more likely to follow safety procedures and had higher life-satisfaction and lower stress levels. For safety managers, the self-efficacy beliefs were positively correlated with better implementation and higher effectiveness of the educational programs and negatively correlated with their company's accident rates.

  • In this paper, for deriving core function requirements of facility maintenance using BIM(Building Information Modeling) customized surveys were conducted with 30 facility managers during 6 momths from July 2014. As a result, 19 core function requirements for efficient facility maintenance are drawn. The core of Building facility management function is that opinions of facilities maintenance managers should be fully reflected than that of BIM experts. In the future, the development of maintenance programs based on BIM should be made fully by reflecting the opinions of building facility managers on the basis of this questionnaire survey results.

  • Due to harsh conditions of disaster areas, understanding of current feature of collapsed buildings, terrain, and other infrastructures is critical issue for disaster managers. However, because of difficulties in acquiring the geographical information of the disaster site such as large disaster site and limited capability of rescue workers, comprehensive site investigation of current location of survivors buried under the remains of the building is not an easy task for disaster managers. To overcome these circumstances of disaster site, this study makes use of an unmanned aerial vehicle, commonly known as a drone to effectively acquire current image data from the large disaster areas. The framework of 3D model reconstruction of disaster site using aerial imagery acquired by drones was also presented. The proposed methodology is expected to assist rescue workers and disaster managers in achieving a rapid and accurate identification of survivors under the collapsed building.
