In contemporary architectural practice, flat sections and plan drawings are no longer a primary means of representation and communication with participants. A typical building design has an ornamental exterior wall system and a roof system that should have water-proof quality and drainage function. By comparison, distinction between exterior wall and roof are unclear in freeform buildings, and they are integrated into a concept of a building envelope. This study is to propose 3D coordinate control technology for freeform structure by CNC curved tube method in order to develop a BIM-based envelope design and construction method for freeform building. Because a much wider freeform building construction can be achieved with correct 3D data and easy-to-implement in construction field, the proposed 3D coordinate control technology is highly recommended for practical use instead of the conventional CAD system.

The recent paradigm shift in the construction industry has led to a growing demand for industrial construction. In particular, interest in modular housing, one of the areas of industrialization architecture, is soaring. Modular housing is a construction method for completing a building by transporting factory-built modules to the site and assembling them. However, modular housing in Korea has various problems such as errors in design books, lack of factory drawings, and lack of on-site construction plans. BIM is a tool for accumulating, producing and managing various information through 3D models and is a solution to solve various problems of modular housing. In this study, problems of modular housing and BIM utilization of modular housing were presented as ways to ensure the quality of modular housing. Therefore, this study analyzed the problems that are occurring in the construction process of modular housing. And, to address the problem of modular housing, BIM utilization measures were proposed for each modular process step. However, the application of BIM in domestic modular project is currently being carried out in pilot research project. Because of this, the BIM utilize method for modular housing is limited based on the BIM use for general projects and the examples for some modular pilot projects.

In architecture, each project participant must maintain organic relationship with others. However, current practices are rather procedural and discrete than organic, which result in considerable inefficiencies. The cool-downs of Korean construction market also force the architects to be familiar with the new construction methods and systems. This research mainly focuses on the pre-development stage of such systems, analysing relationships between the information of architectural design and other parts of construction information like structure, construction, environment, and so forth. The result of analysis can be organized into attributes of members in a physical building, which can be modeled in a 3D system. The resulting model can be used for automated generation of drawing, Bill of Materials, finite element meshes for structural analysis and energy analysis, etc. by extracting meaningful information from it. Hence, the purpose of this research is to analysis the relationship among domain-specific information (e.g. structural engineering, construction detail, energy evaluation) that are represented in drawings, and to represent the attributes of the information relevantly so that they can be applied to each unit task that forms the whole project. Therefore, an object oriented methodology is introduced to compose design informations in three dimension, and expressing properties of building factors and materials, and to construct a database for computers to recognize architecture informations.

Digital models for a cable-stayed bridge are defined considering data-driven engineering from design to construction. Algorithms for digital object generation of each component of the cable-stayed bridge were developed. Using these algorithms, Level-3 BIM practices can be realized from design stages. Based on previous practices, digital object library can be accumulated. Basic digital models are modified according to given design conditions by a designer. Once design models are planned, various applications using the models are linked the models such as estimation, drawings and mechanical properties. Federated bridge models are delivered to construction stages. In construction stage, the models can be efficiently revised according to the changed situations during construction phases. In this paper, measured coordinates are imported to the model generation algorithms and revised models are obtained. Augmented reality devices and their applications are proposed. AR simulations in construction site and in office condition are tested. From this pilot test of digital models, it can be said that Level-3 BIM practices can be realized by using in-house modeling algorithms according to different purposes.

A paradigm shift in teaching modular construction in higher education and K-12 is proposed as a means to increase the future adoption of the modular construction technique. To this effect, a new education module is presented to STEM educators. This education module is based on LEGOs and directed towards educators in the architecture, engineering, and construction (AEC) industry. The main objectives of the education module are to increase interest and knowledge of modular construction, acknowledge the benefits of using 3D design with 4D scheduling, and create a simulating hands-on educational opportunity. The education module is designed to allow participants to experience a hands-on simulation of modular construction and stick-built construction through building a LEGO project. Participants are challenged to find the advantages and disadvantages in both construction systems first-hand and record their findings. Results are presented from the preliminary testing of this education model on a group of construction management students at the University of Nevada, Las Vegas. Overall, the survey results showed that the LEGO education module was successful at achieving the project's three main objectives: 1) increasing the participants' interest and knowledge of modular construction through an interactive project; 2) increasing the participants' understanding of the benefits of 3D design with 4D scheduling over the use of 2D drawings; and 3) creating a simulating hands-on educational opportunity to help participants compare modular construction to stick-built construction. In the end, this proposed a new LEGO education module addressing the problems identified from this study with more participants.

공공 건설공사에서 공사 단계별 합리적인 공사비를 산정하는 것은 국가 예산의 효율적 확보 및 집행 등에 있어 매우 중요한 요소이다. 일반적으로 공사예정가격은 대상 구조물의 설계 종료시점에서 산출된다. 그러므로 대상 구조물의 구체적인 상세 단면이 주어지지 않은 기획단계 및 설계초기단계에서 교량 구조물에 대한 단순 정보만을 가지고 개략공사비를 추정하는 것은 상당히 어려운 문제일 것으로 생각된다. 본 연구에서는 선행연구에서의 61개의 강박스거더교 공사비 분석에 의해 효율적이고 적절한 기획단계 및 설계초기단계의의 개략공사비 산정 모델의 제시 및 타당성을 검증하고자 한다. 연구결과, 본 연구에서 제시된 공사비 산정 모델에 의해 얻어진 추정공사비는 기존에 사용된 방법과 비교할 때 매우 높은 신뢰도를 갖는 것을 알 수 있었다.

공사 완료 시점에는 다양한 마감 공정들이 집중적으로 수행된다. 이는 현장관리자의 업무 부담을 가중시켜 경험에 근거한 임기응변적 품질관리 업무수행을 강제함으로써 감독자나 작업자의 개인역량에 따라 공사품질의 편차가 발생한다. 또한 품질관리와 관련된 정보가 시방서, 도면 등 다양한 유형의 문서에 산재하여 점검사항이 누락되는 경우가 빈번하다. 하자예방과 관련된 정보들을 체계적으로 저장하고, 상호참조 가능한 상태로 연계하여 실무자에게 점검업무 전 또는 수행 중에 효과적으로 제공할 수 있는 도구가 필요하다. 본 논문은 공동주택 마감공사의 품질점검 대상 액티비티 또는 실 단위로 필요한 정보를 체계적으로 저장 검색이 가능한 품질점검 지원 모델을 제안한다. 시방서, 설계기준, 체크리스트, 법규, 하자사례, 도면을 마감공사 프로세스 및 실과 연계하여 하자예방 정보베이스와 정보연계 넥서스를 구축하였으며 이를 바탕으로 정보등록 및 검색 인터페이스를 제시하였다. 내용적으로 다양한 하자예방 정보들을 마감공사 액티비티 및 실을 중심으로 연계하여 활용 가능한 틀을 제시함으로써 일정 수준 이상의 시공품질 확보에 기여할 수 있다.

This thesis investigated construction aims, transitions, and preservation strategies through literatures, old documents, old maps, drawings, and photos and attained results as followings. 'Namganjeongsa' was built and located, centering on the thoughts of 'Song Si Yeol' who adored '$zh{\bar{u}}z{\check{i}}xu{\acute{e}}$'. 'Song Si Yeol' constructed 'Namganjeongsa' on a valley which was situated at a beautiful surrounding with a stream. No writing mentioned that he constructed 'Namganjeongsa', for there was a pond. It seems that the pond was constructed, going through many transitions, after its construction. Neighboing circumstances were damaged when 'Gigukjeong was moved in, 'Namgansa' was constructed, and 'Uamsajeok Park' was formed. So, preservation of cultural assets, together with buildings and environment of location, are meaningful.
