  • With the social demands for tall building, the level of techniques for construction become high and there are various building materials. Also, the construction system become very complicated with the increase of worker. In spite of above facts, the method of construction management depends on the experimental capacity of a construction manager, and there are many unreasonable elements. These elements prevent well-going in construction process. To solve this problem, it is necessary to make a new system of construction management which is adequate for the condition of company and the contents of construction. In this study, the characteristic of production system and the present condition of construction management were investigated with the help of survey. Thus, the new method of construction management which can clear the previous problems was proposed.

  • According to the recent systemic changes such as construction market reduction, five days per week system, introduction of construction duration reduction bidding system and post-construction sale system, the bidding competition have been enhanced. However, there are many construction schedule risks which could delay construction completion. Without the proper identification of construction schedule risks and the structured construction schedule risk management, the competitive advantages of construction project could not be made. Previous researches to solve the problem have been focused on the construction schedule categorization, construction schedule management, and the system development to manage the construction schedule risk. Therefore, this study selected the reinforeced concrete construction as the studied work due to the major impact characteristics on the total construction duration and the quite accident rate, and then proposed the real construction schedule risks of reinforced concrete construction and the construction risk management method based on the previous studies, many times of expert interviews and brainstorming.

  • Larger and more sophisticated building construction requires more input resources such as worker, materials and devices. Growing resource volume brings risks at a construction site. The industry makes an effort to protect probable incidents at the site by organizing a safety management team. conducting a safety instruction and etc, but losses especially in the construction are higher than other industries. Major reason is that the safety management program is conducted only at the step of construction work and a root cause is not eliminated. Conventionally a concerned party shifts the blame to other parties such as constructor and site workers who are direct participants in the construction site. However, the whole causes of incidents go to the all subject of the construction not only the constructor but the client, designer and others related in the construction, and especially the clients are heavily involved in general concerns of the project. Therefore, this study is defined the role of the clients in nations and domestic condition of construction safety management is investigated. And it is analyzed surveys to prevent incidents at construction sites, and suggested the role of the clients which is classified pre and post construction, and in the middle of construction, and also categorized planning and design & construction schedule especially for the pre-construction level.

  • Eventually so as to realize the construction safety, 1 found out the cause of accident and specificities of the construction industry. This study presented to several situations and problems on construction safety. As a result of this study, the below matters must be improved for more effective the construction safety management system. 1. It need to introduce the total construction safety management system. Because there is not effectiveness in the current safety management to the first on the construction field. a. We must consider the safety in the whole parts of the process of the construction and constructors of each part must devide responsibility of the construction safety as a CDM(The Construction Designed Management) used in UK. b. It is desirable to proceed control of safety in the whole parts of the construction to introduce the total safety coordinator that can consult the matters of safety as a law accepted in EU. c. Like management of the construction safety in USA, direction of the construction safety must be made to work exactly by code or manual. d. To improve the organization of the construction safety on the construction field unefficient, it must be introduced safety supervisor, safety coordinator or institutionalization of safety consultant. 2. The law of the construction safety not only have wasteful element but also decrease efficiency by overlapping of regulation, The Ministry of Labour and The Ministry of Construction & Transportation, So laws related with safety must be instituted. a. To realize total safety management, The Ministry of Labour must legislate the basic law about safety management in whole field. b. To legislate the construction safety under one law, and improve efficiency of the overlapping of regulation and the similar law by The Ministry of Construction & Transportation. c. It must be made the law of construction safety that can proper to change of situation in construction. d. The standard of safety must be instituted belong to international level and improved by year. e. We must improve irrational regulation to realize activity of safety self regulating for progress competition in construction industry
