Purpose: The government intends to come up with measures to revitalize safety management at construction sites to shift safety management at construction sites from human capabilities to system-oriented management systems using advanced technologies AIoT and Mobile technologies. Method: The construction site safety management monitoring system using AIoT and Mobile technology conducted an experiment on the effectiveness of the construction site by applying three algorithms: virtual fence, fire monitoring, and recognition of not wearing a safety helmet. Result: The number of workers in the experiment was 215 and 7.61 virtual fence intrusion was 3.5% compared to the number of subjects and 0.16 fire detection were 0.07% compared to the subjects, and the average monthly rate of not wearing a safety helmet was 8.79, 4.05% compared to the subjects. Conclusion: It was found that the construction site safety management monitoring system using AIoT and Mobile technology has a valid effect on the construction site.

Although the construction industry has been rapidly increased at its size and technologies as a locomotive of the economy development in Korea, most construction companies have not paid their attention on the construction risks seriously. However, they have been experienced a lot of business deterioration and project instability during the IMF crisis and WTO entry, and trying to figure out a way to manage the construction intrinsic risks systematically. Some top ranked construction companies have already developed and been implementing a risk management system for the oversea construction projects applying for the marketing and bidding stage, but not for the domestic construction projects during construction phase yet. This paper proposes a construction risk management system model for the site personnel to understand and manipulate very easily in the construction project.

As the international-level concern has been focused on the environmental sustainability in recent years, many researches emphasized the needs for methods and techniques that would facilitate sustainability assessment at the various project level interfaces. As part of methods and techniques to facilitate sustainability assessment, this paper provides 'Computerized Waste Management Performance Evaluation Tool' for the purpose of assessing the level of management system in dealing with the onsite construction wastes. This tool applies twenty-three waste management performance factors for the purpose of evaluating the level of waste management performance by scoring those factors which were identified in the previous research. These twenty-three factors are classified into four categories: manpower, material, method, and management based on their characteristics. In order to quantitatively evaluate the effectiveness of waste management performance, the levels of actions executed in a site by each waste management performance factor were identified and their weight were analyzed throughout the expert interview and survey. Furthermore, an excel-based computerized tool was developed in order to facilitate the evaluation process. If this tool can be developed in more detail and be used as the method to control waste management at a project level for the future, it is expected that this tool can play an important role in the body of knowledge of environmental management in construction industry.

Effective construction safety management systems are desperately required for reducing damage caused by increasing safety accidents in construction sites. Safety accidents in construction sites can effectively protect if proactive measures are taken to prevent unauthorized worker access the expected hazardous area. In this study, we have developed a IoT(Internet of Things)-based dangerous zone alarming system for safety management in construction sites, which can be operated at low cost in large-scale sites as well as small and medium-sized construction sites. The development system utilizes a Zigbee-based beacon technology and cellular mobile communication technology to detect when authorized workers, unauthorized field workers or outsiders approaches hazardous zones. If somebody approaches the dangerous zones the system notifies immediately to the safety manager with a danger warning signal. It is expected that this system can effectively prevent safety accidents when applied to construction sites.

Safety-related accidents are continuously increasing in the construction field. In order to prevent or minimize such accidents, a systematic and active safety activities of on-site managers and workers are required. However, preexisting advance research is lacking on how the safety organization systems are built in construction sites varying in sizes, and how well-trained the related personnel are in safety knowledge and task performances. Especially, a research on the analysis of the formation of their safety knowledge sharing and safety performance cooperation and their visualization is virtually nonexistent. In this regard, this research was conducted with a purpose to study the generalized safety organization method of domestic construction sites, analyze the safety knowledge and cooperation system of the members based on the SNA method and ultimately provide a hands-on data that could be effectively utilized in building an effective safety management system in the future.

As the field report data does not normalize, ordering organization requires different form every time and field reporters make out form as random, data and report to the ordering organization by different medium such as FAX, e-mail, paper document. Therefore, Field reporters must set and make out same information in required pattern. And ordering organization is being responsible for side works of totalizing and processing the reported data. This research suggests the electronic document unification about monthly construction progress report and construction present condition report system. In addition, it suggests electronically processing function that can handle field report business to unifying electronic documents. As using the result of this research, it will improve the work efficiency and simplify in report business.

국제관광도시로서의 명상을 돈독히 다지고 있는 제주도. 최근 이곳의 관광업 관계자들은 물론 지역주민들은 한껏 기대감에 부풀어 올로 있다. 바로 롯데건설(주)이 시공하는 제주시티호텔이 다음 달이면 준공될 예정이기 때문이다. 실제로 이곳은 제주도 내에서 가장 높은 건축물(90m)로 탄생하면서 랜드마크 역할을 톡톡히 할 것으로 전망되고 있다. 이곳 현장은 지난 2011년 8월 구 제주일보 사옥 철거공사를 시작으로 2011년 12월부터 TOP DOWN 및 UP-UP공법을 병행하여 토공, 골조공사를 본격적으로 착수했다. 현재는 공정율 85% 수준으로 건물외부 코깅작업 및 내부 인테리어 마감작업이 진행 중이다. 이곳이 특히 주목받고 있는 이유는 롯데건설(주)의 안전관리 기술력이 집약된 또 하나의 건축물이라는 평가를 듣고 있기 때문이다. 롯데건설(주) 관계자들은 이곳에 면세점과 호텔 등 다중이용시설이 들어서기 때문에 부실시공은 곧 대형안전사고를 불러온다는 인식을 바탕으로 빈틈없는 안전시공을 해나가고 있는 것이다. 이는 물론 현장 근로자들을 대하는 안전관리에도 고스란히 나타난다. 착공부터 현재까지 무재해 100만 시간을 앞두고 있다는 점이 이를 잘 증명한다. 안전으로 제주도의 새로운 명소를 건서래 나가고 있는 롯데건설(주) 제주시티호텔 신축현장을 찾아가 봤다.

The government and of the Safety and Health Corporation have continuously carried out safety activities such as supervision, inspection, technical guidance and financial support in order to reduce accidents on the construction site. However, the number of disasters on the construction site is increasing every year, Which accounts for more than 80% of the total number of casualties. It is necessary to investigate the implementation status of safety and health management in the field of small-size construction site, and to provide the appropriate technical guidance plan to the relevant work places. Also, it is necessary to reduce the disaster at the small-size construction site, The purpose of this study is Improvement Plan to Enhancing the Effectiveness of Technical Guidance Project for Safety Control of Small Construction Site.
