The structural work is the main process of building construction which influence on the time, cost, safety and quality. The form work is one of the main process which has from 20 to 30 percentage of structural work. Especially the form work for beams is complex and need more manpower compared with form work for column or slab. When the existing forms such as plywood form, steel framed wooden form and aluminum form, is used for form work of beam, it would result in the cost overrun caused by needs of lots of manpower and resources. Therefore, the aim of this study is analysis of the requirement for development of SMART beam form. The result of this study shall be used for the development of SMART form work system.

Recently, construction in downtown is often done closely at the adjacent building. In this case, underground construction need to Basement Composite Wall(BCW) construction. However, generally, during the construction process of BCW form works have many problems that are narrow working space and inefficient time consuming. Despite of these problems, there was no quantitative research for the work time of BCM assembly. Therefore, in this study, work time of CBW form assembly in underground construction is identified by the work analysis. The results of this study reveal that buttress work of basement form take lots of time in the entire work process of Basement Composite Wall form assembly.

벽식구조 골조공사에서 거푸집공사는 원가에 지배적 비율을 점하고 RC 구조체의 중심공법으로 활용되고 있기 때문에 체계적이고 효율적인 공법개선이 요구된다. 이에 본 논문은 거푸집공사의 품질 및 생산성향상을 위한 공법개선을 목적으로 한다. 과학적인 분석기법을 통한 기존 벽식구조 거푸집공사의 문제점을 개선하고자 생산성 분석기법인 워크 샘플링을 활용하였다. 개선안을 도출하기 위한 방법론을 제시하고, 개선방향에 따라 거푸집공사의 품질 및 시공단순화를 위한 유닛화 및 기계화 방안으로 키커폼(kicker form)을 제시하였다. 이는 거푸집공사 수행에 있어 불필요한 작업프로세스를 줄이고 생산성 및 종합적인 시공품질이 향상될 것으로 판단된다.

Lately Construction industry has been depressing by hard construction market circumstance. Construction company, especial at this time, makes more rationalize the management of inside Company and Construction field. In this study we are to present the method of calculation reasonable duration at Reinforced Concrete Work. For the study first make up a question at field workers, then sampling the Form workers based the question. Second, We are using Work Analysis Method analysing the worker's work-method and Time. And then using the result of analysis, measure the Productivity of Form work. The productivity of Form work is used the basic data of duration at Reinforced Concrete Work

Form-work is a must for construction work. In order to secure the best condition of the form surface and to increase the number of times, the form releasing agent is applied during the process of the form-work. The base oil of the form release agent which has been used already uses the oil which directly or indirectly affects the natural environment and the concrete. In this study, the basic study on the form release agent for concrete was carried out only for the effect of adhesion. The adhesive force of the tile is measured by the mortar to determine the change of the releasing agent and the adhesive strength.

Nowadays, the stripping work of form has generated some problems such as increasing total constructing cost result from delayed work schedule by the stripping work of form and environmental issues by wasting the debonded form. According to recent research for form work, it has studied about permanent form to solve economic and environmental problem which is commented above. In this study, high performance permanent form method was developed and tested by adopting COM and TEN specimens adopted on the Compression and Tensile section then the structural behaviour was investigated. In the test result, the specimen adopted the form showed better structural performance than control specimen in the point of ductility, failure mode and ultimate load.

This study surveys the types of form works used for constructing composite basement walls found in domestic construction sites. Based on expert surveys, the research provides criteria for selecting a form work type and cost-benefit analysis for different types of form works. In selecting a form work type, safety was considered the most important factor. It is induced from the survey that a successful construction requires a form work type that could solidly bear the lateral pressure of concrete rather than other types that cut back the cost and shorten the construction period. In the cost-benefit analysis, the benefit was the highest in 'euro-form+soldier system', and the cost was most competent in 'rib-lath+soldier system'. In considering benefit and cost together, 'euro-form+soldier system' was judged to be the best option. This is likely to be attributed to the following reasons: site workers are familiar with euro-forms because it is the most widely used; and, soldier system is more reliable in bearing lateral pressure compared to steel pipes.

Construction accidents have not decreased in spite of much effort such as new work methods, education and research related to safety works. Specially, many fatal accidents happened in construction works which involve the apartment, building, school, church, hotel, hospital, bank work and the other works. These accidents are mainly caused by unanticipated risk factors. From these reasons, this study researched fatal accidents which happened in construction works during last 13 years($1992{\sim}2004$) and analyzed the input workers and a work period of construction work. According to the input workers and a work period, the results are as following. During 13years($1992{\sim}2004$), the fatal accidents, related to the construction work, were happened to the 1,977 cases. These results were occupied the 21.32% of the total industry accidents. According to the result of the construction, the fatal accident rate of a concrete form work was the highest rate of 16.24% (321 cases) and a temporary work, a steel frame work was the each rate of 12.39%(245 cases), 10.07%(199 cases). Comparing to other work types, the fatal accident rate of those three work types(concrete form work, temporary work, steel work) was represented highly. We surveyed input workers and work period of construction work site. From the result of survey, input workers of a concrete form work were occupied with 13,720. The risk rate of the work type, which was considered input workers and work period, was represented 0.3622(a steel frame work), 0.1142(a temporary work), 0.0782(a tower crane) and 0.0772(a concrete work).

In the relationship between exhibition space and art work in art museum, the Pluralism on the late of the 20th century made the new form of exhibition space to be appeared on the stage. Even if formal exhibition space that emphasized itself as a non-spatial background is currently being continued, the informal form of exhibition space is coming to the new art museums, especially after 1990's. This study is to understand how the advent of new designed the informal form of exhibition space in the Glytothek museum(the formal form of exhibition space) design a new paradigm In the relation between the exhibition space and art work in conjunction with public's perception. To do this, it is made clear that the Glytothek museum(the formal form of exhibition space) simply has played a role of non-spatial background. In other hands, the new designed informal form of exhibition space that is mainly presented after 1990's begins to Interrupt the public's perception of art work, changing it's meaning through a spatiality.
