Nowadays the widely used media in architecture include visualizations, animations and three-dimensional models. 3D digital methods using active CAM(Computer Aided Manufacturing) and CNC(Computerized Numerical Control) imaging have been developed for accurate shape and 3D measurements in freeform buildings. In contrast to a conventional building using auto CAD system and others, the proposed digital optimization method is based on a combination of 3D numerical data and parametric 3D model for design and construction. The objective of this paper is therefore to present digital optimization process for constructability of freeform building. The method can be useful in the effective implementation of an error-proofing process of freeform building during design and construction phase. 3D digital coordinate data can be used effectively to identify correct size of structural and finish members and installation location of each members in construction field. In addition, architects, engineers and contractors can evaluate design, materials, constructability and identify error-proofing opportunities. Other project participants can also include representatives from all levels of management, departments as well as workers and key subcontractors' personnel, if necessary. The 3D digital optimization process is therefore appropriate to serious variations in freeform shape. For future study, the developed digital optimization method is necessary to be carried out to verify the robustness and accuracy for constructability in construction field.

The objects of this study are to increase the efficiency and competitiveness for construction management and field supervision by using IT technology which is a trend of construction industry thesedays. Using RFID technology can play an important role to achieve the goal, but it is necessary to research a standard of using frequency, specific, protocol, package method and reading method because it is hard to apply RFID to physical, chemical, environmental specifics. In this study as a part of planning research to standardize, a limitation item Is conducted with RFID tag attached building materials, and RFID Tag goods which solve the restriction are produced to conduct a field application test. From the result, available reading distance is different according to physical and environmental specifics. Furthermore because the different application method and attaching method make a various management efficiency, the current management of construction materials is analyzed and applied to a construction field to provide to various limitation items and recovery plan.

Building information modeling (BIM)-based construction projects have increased and become more varied, and as such the management of BIM-based facility information is also increasingly important for facility maintenance. Information management, and specifically product data mapping, however, has some problems in the area of manual data entry and does not adequately consider the exchange requirements of facility maintenance. Therefore, it is necessary to introduce a method to improve the management of composite object information for BIM-based facility maintenance so that it can handle construction operation building information exchange (COBie) data for a composite object. Therefore, we present a method to map COBie data to related materials of a composite object. This research contributes to increasing the efficiency and accuracy of the required information mapping between a building model and product data using a BIM library through optimal BIM data adoption. Moreover, it allows for the creation and management of specific product data at the design development phase.

상업간판은 단순한 광고목적 외에 도시의 시각이미지를 구성하는 도시환경구성요소 중 하나이다. 또한 건축물의 주요한 구성부분이며 주민에게는 환경적 즐거움을 주어야 하는 의무가 있으며 보행자로 하여금 강제적으로 주목을 끌게 해야 하는 상업적 목적을 가지고 있다. 그러나 본래의 목적과 달리 하나의 도시환경저해요소로서 문제점을 유발하기도 한다. 이러한 문제점들을 시정하기 위한 주민과 자치단체의 상업간판 환경개선을 위한 시도와 이에 따른 결과를 살펴보면서 환경개선을 위한 시도가 결과적으로 주민과 도시환경 모두에게 어떠한 영향을 끼쳤는지를 살펴보았다. 현재 한국의 간판게시규정은 중앙집권적 규율하의 기본규정과 비효과적인 부처간의 상이한 규정 및 하급세부규정의 미비에 기인하여 상업간판의 난립상황을 초래하였다. 아울러 살펴본 일본, 미국, 프랑스에서 적용하고 있는 기본규정도 한계가 있음을 살펴보았으며 따라서 어떠한 개선방향이 주민과 자치단체 양자에게 이익을 주고있는지를 살펴보았다. 효과적인 간판설치규정의 제정은 불가능하지만 규정은 제정하되 무엇보다 자발적인 주민들의 참여와 건축가, 사용자, 자치단체 사이의 주의로운 조화가 필요함을 살펴보았다.

This study examined cases of duplication and confliction of legislation related to fire safety in long-term care facilities. In addition, the aim was to provide implications about those cases in the perspectives of welfare for the aged. In relation to fire protection facilities, long-term care facilities are regulated by the Building Act and Fire Protection Act. Among those Acts, certain gaps, and conflicts by duplicated regulations were found. Although the related-acts have improved gradually, unsolved issues and retroactive applications still remained. The problems stated above were defined by reviewing specific cases and legal improvements in the perspectives of welfare for the aged were suggested.

Quality control (QC) is an essential work for the successful construction project execution. Recently, robust application of ICT to the QC tasks leads to utilizing innovative technologies and equipment. However, overall planing of QC works needs to take place before applying new technologies to each and individual QC task. The objectives of this research involve developing a database and an algorithm that identifies QC tasks and related information upfront. In addition, the researchers developed a methodology to generate inspection tasks in conjunction with construction work tasks. The Korean Ministry of Land and Transportation provides standard supervision checklists. They were classified based on criteria of inspection items, methods, period and the scope. Reinforced concrete work was selected as a case study for validation of the method. This framework can function when planing construction tasks with any type of planning tools and innovative technologies. The researchers expect this framework may contribute to various construction projects when developing QC plans and tasks with applicable technologies.

Construction industry pays attention to modular construction recently which based on factory production not on labor intensive site production. Since modular construction has high time shortening effect and easiness of demolition and recycling, it has been applied to the temporary residential building. Domestic modular construction market are not activated yet, however, due to the high initial cost to realize modular construction. This study proposes demand-sensitized movable modular building in order to reduce the financial burden. The study compares between RC method building and Modular building which moves building when the demand falls off from Life-Cycle Cost's viewpoint. As a result of the economical evaluation, RC method achieved profits faster than Modular model, but Modular model's gross earnings during the life-cycle are much bigger than RC method. In other words, the result means that the market-sensitized movement of the modular building would be an economci choice in Life-Cycle Costing aspect.

ZEB is a building that increases the energy independence of the building itself, and new and renewable elements that can produce energy are essential, and BIPV is the most notable technology. In ZEB's design, BIPV should be planned early in the design, but BIPV plans are insufficient in the early stages. Therefore, this study derived elements for theoretical consideration of BIM and ZEB and analysis of ZEB independence rate based on BIM, a convergence design technology, and analyzed BIPV energy production and building energy consumption. Finally, by calculating the energy independence rate and reviewing the rating criteria in the project model, a basic research method for calculating the energy independence rate of ZEB at the beginning of the design was presented. Through this, it is expected that design productivity can be improved by supporting the decision of ZEB subjects.

This study reviewed the status of domestic and foreign Architectural Information Systems and related laws, analyzed the state of the architectural service industry, and proposed the phased introduction of BIM into Architectural Information Systems. The adoption of BIM in Architectural Information Systems both at home and abroad is generally at an unsatisfactory level, with only Singapore assuming a leading role in this area through activities such as the provision of a separate BIM submission service. Since it is desirable for BIM to be applied to additional types of architecture when the architectural licensing procedure is introduced, the different phases of adoption were set after analyzing the scales and types of architecture as defined in related laws. By analyzing the participation rates of architectural design firms in each scale of architecture design, the results demonstrated that, as the number of floors and total floor area in the building increases, the proportion of small scale architectural design firms involved decreases, while that of large-scale architectural design firms increases. The adoption of BIM is occurring mostly within large-scale architectural design firms, which is why it is desirable for its introduction into Architectural Information Systems to be separated into phases from large-scale buildings to increasingly small-scale architecture. In conclusion, this study divided the adoption of BIM in Architectural Information Systems into 6 stages and, following the Architectural administration procedure, established a segmented road map for the gradual activation of BIM.
