Currently, the construction industry is decreasing every year due to people's poor perception, high labor intensity, unstable employment structure, and welfare problems, as people avoid entry. Accordingly, this study investigated how to attract trainees and graduates from domestic construction education institutions to the construction industry. If institutional devices are prepared to prepare for the future by improving the welfare system such as unemployment benefits and retirement deductions in the construction industry, many trainees in their 20s and 30s will be attracted to the construction industry. If it helps expand hands-on education through on-site linkage and has the necessary technical skills for practice, it is believed that trainees and graduates in their 4s and 60s will be attracted to the construction industry.

Because that construction project is usually uncertain and the plan of it changes frequently, it is difficult to make a reliable and feasible plan for it. As the BIM technology is developed, we can simulate the future of the construction project visually and make more reliable plan. However, data production efficiency is not so high, it is used just for animation and presentation usage. Although, a lot of construction simulation systems are developed, it is difficult to measure performance of them. In this study, we defined the construction simulation work process and the scenarios to measure performance of them. The performance measurement method using simulation process scenario can make possible benchmark test of them.

Modular construction has benefits such as short construction duration and high productivity owing to the production in factory and owing to simultaneous on-site work. However, rework occurs in modular construction and the rework affects the efficiency of modular construction. The almost of causes of rework are exist in design process. To reduce the cause of rework, the information flow of the design process should be managed and the plan to reduce rework should be included. However, the modular construction has complex process because of impeded unit production so it is hard to manage the information flow in design process. Moreover, when the plan to reduce rework is included, the design process will be more complicated. Therefore, the objective of this research is to suggest the design process including the rework reduction plan and to alleviate the complexity of design process by using Dependency Structure Matrix(DSM). By using DSM, the iteration and feedback in design process is reduced and it can be expected that rework in modular project can be reduced by using suggested design process.

Purpose: The purpose of this study is to provide an effective construction project cost estimation tool for preparing a business plan of healthcare facilities which can be practically used for development projects. Methods: In order to provide a tool for calculating construction project costs, this study analyzed the Building and Related Laws, the Building Technology Promotion Laws, the Ministry of Land, Infrastructure and Transport notifications and directives, the Ministry of Trade, Industry and Energy notifications, the detailed guidelines of the Ministry of Strategy and Finance, the Building Service Industry Promotion Acts, various certification standards, actual project budget calculation cases, etc. with advices from related experts. Results: 1) Construction cost is classified into construction costs, architectural design costs, supervision costs, incidental costs, and each sub-element. In particular, since there are many incidental cost items, essential items to be reviewed during planning are derived and costs are calculated according to appropriate consideration criteria. 2) Criteria for Payment calculation mainly applies the construction cost rate method or the actual cost fixed amount method in consideration of the characteristics and scope of work. Implications: There are many calculation factors that need to be applied to the construction project cost. Therefore, it is necessary to organize the calculation process more clearly.

Due to recent trends of the atypical plan shapes and the zoning construction in high-rise buildings, the building stability under construction is arising as an important issue for design and construction plan. To ensure the stability under construction, the differential column shortening and the lateral movements with unbalanced distributions of self-weight of structure members and the load flows before completion of member connections and lateral load resisting system should be checked by construction sequence analysis. This paper presents the scheme of zone-based construction sequence analysis, to check the stability of high-rise building under construction. This scheme is applied to the construction sequence analysis for real high-rise building under construction.

For decades, the productivity issue has been a primary concern for the all stake-holders who participate in domestic construction industry. Especially, between a whole life cycle of building, the construction phase's productivity problem makes or break the entire project. In this respect, the general construction company, who accept the order and construct the building(so called General Contractor), should consider various strategies, such as schedule management, cost management, quality management, inner-crew management, etc., for the productivity improvement., and almost of these management methods have been studied for a long time. But, the researches and studies about the specialty contractor, who construct the building directly in construction site were not sufficiently complete yet. This research begins as an idea which tries to apply the BIM(Building Information Modeling) into the tasks of Specialty contractors for their productivity improvement. And for the effective application of construction BIM to specialty contractors, establish of the BIM project execution plan for them, not the fragmentary adoption of BIM. Therefore, in this paper, we develop the BIM project execution plan for the reinforced concrete companies who conduct the framework construction which located on CP(Critical Path) Especially, we model the "Construction BIM Use List for the RC Work", "BIM Application Master Process" and "BIM Application Detailed Process", and general contractor who use these BIM uses list and process models can manage various specialty contractors about schedule, cost, earned value, quality, safety and environment management systematically.

Information technical dependence degree is coming to be high from constructive information-oriented field. The size and complexity of constructive information are increasing and consequently, the standard for a construction information resource management becomes important. Currently the certification about construction information standard is being enforced part system and information-oriented level etc. from domestic. So we have a plan which will propel the diffusion strategy for the practical application of constructive information standard with introduction of the certification system about construction information standard. For a certification system preparation, we studied a feature and definition about construction information standard and analyzed domestic and foreign case. From that, we accomplished a classification and an analysis about construction information standard becomes the object of certification. And then, we selected the object of the certification through deriving necessities of certification about each construction information standard and considering the priority at the time of introduction. Finally we suggested an certification institutional operation plan about the object which is selected. Held a consultation meeting about the fact where the professional knowledge or technique is demanded and established secured directivity about authentication institutional operation plan and professionalism.

As hospitals change continuously and rapidly, the way of growth and change becomes another important factor in the design of a hospital. The hospitals are adapted for the continuous growth and change during their life span. But the hospitals built in 1970's and 80's have been expanded and reconstructed without any plan of growth and change. So, there is required to the architectural planning on the remodeling and modernization strategy of general hospitals. The purpose of this study is to provide the fundamental data for the reasonable design planning and the basic principles of the construction plan in the hospital remodeling. Thus, this study is to investigate and analyze the characteristics of hospital remodeling, the remodeling planning, and the scheduling process in terms of construction. As a result, this study would apply to design guideline for the remodeling of general hospitals.

After the historic opening of the first section of KTX(Korea Train eXpress), it has been made changes three times in a plan to pass through cities of Daejeon, Daegu in the construction of the high speed train's second section(underground${\to}$ on ground${\to}$ under ground${\to}$ on ground). Thereafter, it has been repeatedly argued that the plan to pass through underground caused many problems such as prevention of an accident in tunnel, the difficulty of maintainence, the disadvantage of passengers' moving line. Thus construction on ground plan is coming up again with relation to the interest among local people. There have been lots of national budget loss, construction period delay in this project and people hardly trust policies about national project and nor do engineers. It will be presented that the railway line which is accorded with the characteristics of region, an agreement with local communities about national project, the reasonable procedure to determine how to pass through cities, resolve the conflict among neighborhood, and the role of engineers.
