Community facilities in apartment complex have been developed through construction companies' needs for housing development and differentiation combined with a intense marketing competition among housing construction companies. But, It is the fact that the construction companies have planned the community facilities without considering on residents' needs for housing environmental amenity and preference. Therefore, this study investigated the space composition and the present usage of community facilities and surveyed to get concrete information regarding the residents' satisfaction with the proposed community facilities plan. It is the conclusion that the residents request a convenient and comfortable facilities similar level with those in the outside sports complex and the operating programs.

Today's construction is more various and more complex. Because of that, a lot of uncertain factors are occurred and they related uncertain construction duration. For management complex architecture project, importance of construction schedule management also increased. In previous studies, one of solutions to overcome those problems is suggested. It was BIM based construction simulation process which focused on construction schedule and construction schedule management. But latest process had limited point which has no duration estimation function. So this paper suggested duration estimation method and developed duration estimation module. Duration estimation module developed with current scheduling tool MS Project and their macro function. However, this module has just developed Reinforced Concrete Structure and has to do more development and research.

The so-called Korean BNC (bound noun construction) displays complex syntactic, semantic, and constructional properties. This paper, couched upon a constraint-based approach, two different syntactic structures for the construction with articulated lexical properties for the BNs and relevant predicates. The paper reports an implementation of this analysis in the LKB (Linguistic Knowledge Building) system and shows us that this direction is robust enough to pare relevant sentences.

Because irregular shaped buildings are designed with various three-dimensional curves, the difficulty of design and construction is very high, and more construction drawings are needed to reduce construction errors. General 2D drawings may have limitations in conveying the information necessary for construction. By utilizing BIM, it is possible to three-dimensionally design parts that are not expressed on 2D drawings and additional structurall components required for the construction of the curved exterior finishing materials. This study examines the necessity of BIM at the construction stage, its performance through it, and how it can be linked to smart construction technology through construction BIM being applied to the new construction site of Sejong-Pocheon Line Cheoin Rest Area.

As environmental Problems are increasing, many attempts to solve problems and preserve environment are appearing around the world. Not only in construction, but also dwelling life, residents attend many activities to improve environmental problems. Ecological development example of Freiburg in Germany was focused in this study to show the direction of development of environmental friendly housing complex in Korea. The target of study is Vauban Housing Complex of Freiburg in Germany. The study methods are literature study and field trip. Contents of the study include 1) formation process of the complex 2) physical environment of the complex 3) environmental friendly factors of the complex 4) environmental friendly life style of the residents, etc. Result of this study is as follows. Vauban Housing Complex was remodeled from the existed army buildings by residents themselves through education and negotiations. Residents' life satisfaction and housing adaptation level were high on the whole. The principle of the complex formation was use of natural feature itself in maximum against developing in minimum. For instance, construction materials, energy saving, resources saving were planned and used carefully. The residents led community successfully according to environmental friendly life principles. In conclusion, the persistent study on environmental components is necessary that is suitable to Korean situation.

Construction projects have become increasingly complex in recent years, resulting in substantial safety hazards and frequent fall accidents. In an attempt to prevent fall accidents, various safety management systems have been developed. These systems have mainly been evaluated qualitatively and subjectively by practitioners or supervisors, and there are few tools that can be used to quantitatively evaluate the performance of safety management systems. We propose an expertise-based safety performance evaluation model (EXSPEM), which integrates a fuzzy approach-based analytic hierarchy process and a regression approach. The proposed model uses S-shaped curves to represent the degree of contribution by subjective expertise and is verified by a genetic algorithm. To illustrate its practical application, EXSPEM was applied to evaluate the safety performance of a newly developed real-time mobile detector monitoring system. It is expected that this model will be a helpful tool for systematically evaluating the application of a robust safety control and management system in a complex construction environment.

As buildings become taller and more complex, the number of high-rise and underground complex buildings is increasing, but risks are also increasing due to the limitations of existing evacuation safety methods. Through this study, we will analyze the fire and evacuation characteristics of high-rise and underground complex buildings, identify problems with the current evacuation safety method, and seek ways to improve them using digital technologies

The outer surface of an irregular structure contains panels with two-directional curvature called NURBS. To construct these forms of exterior materials, complex geometric surface should be divided into forms and sizes that can be manufactured and constructed. Because the bigger the curvatures of these divided exterior panel, the more expensive the construction costs, these complex two-directional curvatures should go through optimal process of reinterpretation to minimize the curved surfaces with complex two-directional curvatures. Yet, to gain higher ground in technological competition in the field of irregular structure construction, companies do not share know-how that they obtained. Accordingly, small construction and design companies have trouble calculating even rough estimate and cannot adjust expected construction cost based on comparison of design alternatives. Given this situation, this study conducted the research that can support decision-making in the design stage of the construction and provide basic material for optimal range to reduce manufacturing cost by the minimizing the distorted plane of the irregular structure.

Underground environmental infrastructure and energy production facilities, which are recognized as avoidable facilities such as landfills, are emerging as an important social issue due to urbanization and economic growth. It is necessary to analyze the stability according to various ground conditions and load conditions for the construction of large-scale underground complex plants. In this paper, horizontal/vertical displacement and stress distribution according to the load condition and construction process were analyzed using finite element analysis (FEM), Based on the analysis results of various conditions, factors to be considered in the detailed design and construction of the underground complex plant were reviewed and the implications on design factors (Intermediate wall installation status, Pre-reinforcing area, etc.) for underground large space construction were derived.

In addition to the waterproof sheet waterproof objectives that apply to the building roof it is being constructed, including a complex such as insulation performance, root-resistance. However, thermal insulation of the composite waterproofing sheet is an insulating effect a wide variety depending on the specific construction -specific, material and even the effect is this part of the test to the generation when insignificant compared to each other a number of roof insulation effect of the insulation composite waterproof sheet that is currently in effect analysis.
