As characteristic of construction industries, the Issues of construction management have been pointed out because of time and space limit among construction project participants (owner, supervisor, builder, experiment specialty institute, specialty construction company, material supplier and equipment supplier). To improve these issues, procurement system has been introduced by using internet and intranet. Procurement system that was developed by some of large construction companies was considered only internal supply on closed system method. They also restricted to article supply as supply concept. In this paper, we suggest a plan to establish integrated construction procurement system that expands to the article, service and construction work supplies by utilizing the bi-directional and real-time contact system and presents related following research program.

This study is to investigate the degree of field awareness of how each provision of the Serious Disaster Punishment Act will affect accident prevention. As a result of conducting a survey of construction site workers, it was analyzed that construction site workers had a low sense of safety and did not voluntarily engage in safety activities. And it can be seen that they are taking a very passive position that it is efficient to implement safety under the supervision of the supervisor. Workers who need voluntary construction site safety activities are most aware of the situation at the site, but the problem was pointed out as "lack of procedures for listening to opinions and preparing improvement measures" for these problems. Future research is needed to see if this is a problem for individual workers or for those in charge of safety and health who do not correct it even though active opinions have been submitted.

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.

This study aims to derive key construction supervision work that can be digitalized among construction supervision work. The scope of the study includes domestic construction sites to which the Building Act of South Korea is applied. First, the construction supervision process was identified through extensive consultation of construction expert witnesses. Afterwards, the key construction supervision works for digitization were derived through survey results construction expert witnesses. Among the 24 supervision works throughout the pre-construction, construction, and post-construction stages, the proportion of supervision work manpower or cost, the type of data generated by supervision work and the urgency of introducing digital technology, and the impact on productivity and safety of supervision work were evaluated on a 5-point scale from "very low" to "very high" was investigated. The survey was conducted by t-test analysis, and as a result, it was possible to derive that the level of digitization was higher than average in "quality management," "safety management," and "collection and cooperation of maintenance instructions." It can be interpreted that digitization has been introduced on a pilot testing basis or has already been completed according to the needs of the site. On the other hand, it can be interpreted that the work that are obtained below the average score are considered to be realistically constrained at the construction site and that it is inevitable for the supervisor to proceed manually. Future studies include analyzing the quantitative impact of the key construction supervision work once digitalization is fully applied.

Government needs a risk assessment method that is effective in preventing accidents as a part of the three principal projects of the government for protecting the people's lives for establishing preventative measures to prevent accidents in the construction sites, which accounted for more than half of all accidental mortality accidents, and promote the safety-oriented culture for making fundamental changes. Accidents at the medium and small sized construction sites accounted for 88.9% of the total construction accidents. The data indicates that improper management and lack of advanced safety measures due to the absence of a safety supervisor are the biggest problems. It is believed that active measures to evaluate and prevent risks at construction sites are necessary for preventing accidents in the medium and small sized construction sites. The objectives of this study is to identify the key risk items of common accident causes and propose a practical, preemptive, and improved risk assessment method by evaluating the problems in the safety management of construction sites for reducing the accident rate in the medium and small sized construction sites.
