Recently, the number of complex construction projects, such as high-density development and long-span mega structure construction, has been increasing globally. Therefore, the construction duration has become an even more important factor for success. Nevertheless, in domestic residential construction projects, it usually takes more time than twice as much as North American cases. The long construction duration causes a number of problems, for example growth of financial costs, fall in productivity, and weakness of competitiveness. If the framework construction duration can be shortened to 3 ~ 4 days, then it is also expected to complete the finish work of building in shorter duration, be led to reduce the entire construction duration, and eventually to save a great deal of indirect costs. For shortening the construction duration, previous researches pointed out that the development of simplified plan design should precedes. But, in reality, lack of experience of new design and innovative techniques tends to be the obstacle to wide adoption of the simplified plan design in construction fields. In this paper, a simplified structural plan design is proposed, and the construction cost is quantitatively compared between when traditional construction technique is applied to the traditional plan and when the duration-shortening key technique is applied to the developed plan.

Although the safety management plan review system according to the Construction Technology Promotion Act for securing the safety of the construction work is a fundamental system essential for the prevention of the construction industry disaster, the necessity of its improvement has been raised because it often fails to meet the original purpose. In this study, through the analysis of the effect of the safety management plan and the problems of the operation, we suggest ways to improve it in view of the construction accident reduction and conducted surveys on the construction site through the questionnaires of the client, construction company, and construction business technology manager. In order to improve the effectiveness of this system as a result of the study, it is necessary to distribute the guidelines for the preparation of the safety management plan, manuals, etc., to simplify the contents of the safety management plan, also the step-by-step approval of the safety plan can be a solution. For this, it is necessary to revise the policy through consultation with the Ministry of Land, Transport and Maritime Affairs and related experts.

The production plan of Precast Concrete members is closely related to the assembly plan of Precast Concrete members, and is an important management factor for the process planning of Precast Concrete construction. This may cause a delay in the construction period due to manufacturing errors occurring in the production process of members and transportation errors according to the production sequence. Therefore, it is necessary to have an efficient production plan for Precast Concrete members that can produce the necessary quantity from the point of assembly of the members and supply them in a timely manner. This study is a basic study for establishing a production plan for Precast Concrete members, and the purpose of the study is to examine the factors that affect the establishment of a production plan for Precast Concrete members. In this study, the influencing factors according to the production method and conditions when establishing a production plan for Precast Concrete members were considered. In the future, correlation analysis among influencing factors will be carried out, and it is expected that it will be used as basic data for schedule management of Precast Concrete construction and derivation of construction period calculation standards.

Recent economic slump has highlighted the needs for the construction industry to develop strategies to improve productivity and overhaul organization structure. Notably, it is urgent to improve productivity of apartment building construction projects that account for about half of the aggregate revenue of building construction projects in Korea. As construction site management manpower staffing plan has close relation with the productivity of building construction, it is essential to staff construction sites adequately in consideration of site conditions and characteristics. However, construction companies of Korea are still far from developing site management manpower staffing plan in reference to quantitative standards. Therefore, this research aims to analyze site management manpower staffing plan of apartment building construction project by means of density analysis. To be more specific, site organization charts and staffing plans of apartment building construction projects put together by large construction companies in Korea are studied and essential resources and their mobilization time of apartment building construction projects are examined. Conclusions herein will provide basic inputs to subsequent studies of apartment building construction site management manpower staffing standards.

Lifting plan in conjunction with the overall construction plan will be established. It is being created by executive director of the Corporation and other such as an experienced site manager. But, written lifting plan based on the limited information and experience is causing some problems such as decreasing productivity, workability loss, delay. The reasons for the problems are lack of prediction of construction execution, inappropriate materials on the past performance, individual experience, limits of knowledge, lack of technical materials, shortage of advisor. Therefore, to solve the problems, we have to overcome the situation in which we depends on lifting planner's experience and intuition, limited information by accumulating objective and reliable materials. Because unorganized lifting plan will lower efficiency of lifting equipment and make reducing construction period difficult. In this study, influence factors on lifting plans will be derived through reviewing literatures and lifting plan cases. Derived influence factors will be classified as components and classes, classified influence factors are assessed suitability. Also, Decision making items are derived from the factors. Finally, tower crane lifting plan process will be suggested from the result.

The duty of construction clients in WSH (Workplace Safety and Health) system was included in the amendment of Occupational Safety and Health Act (enforced on 16 January 2020), which was estimated the shift of paradigm in the prevention of construction accidents. The purpose of this paper is to introduce the analysis results of construction clients' role in the construction project, which were performed by authors over the recent years in order to impose the duty on construction clients, and to suggest their role according the plan, design, and construction stage. Utilizing the systematic literature review process based on Meta analysis, the related papers were selected. For the selected papers, related domestic and foreign regulations, and other prominent report, the construction clients' role was analyzed by reflecting the experts' advice. Results show that the construction clients should control the designer and contractor for implementing the WHS system during the whole process of the construction project. They should supply sufficient source and time to ensure the workers' safety. In the plan stage, the key role of construction clients is to identify intensively controlled hazard and risk reduction plan and to transfer the results. In the design stage, their key role is to select the designer with the capacity in WSH and to assist the designer for the safety design. The main key role of construction clients in the costruction stage is to select the contractor with specialty in WSH including a contract reflecting the WSH requirement and to check implementation of WSH plan, WSH cost, WSH education, and accident report. In addition, it is thought that the construction clients' participations in the site WSH activity and adjustment of safety and health problem among contractors can be effect in the prevention of construction accidents.
