In this study multi-zone modeling program CONTAM 2.4 which is developed by NIST is used for modeling the air disinfection system which is consist of dilution, filtration, ultra violet germicidal irradiation (UVGI) for removing the indoor microorganism such as bacteria and fungus. Developed models those protect occupants against indoor microorganism generated in our daily life are enable to use for immune building simulation tool. Also, results indicate that those models are enable to compute the real situation that is almost impossible of carrying out experiment and identify the disinfection rate with highly reliance. Results also suggest that engineers will use these models as a design tool for the immune building system.

본 논문에서는 건물 부재간의 수치비례 관계를 이용한 Parametric Modeling 방식을 통하여 효율적인 전통목조건축물 구현을 제안한다. 제안한 방법을 사용하여 우리나라의 대표적인 전통 목조건축인 경복궁 근정전의 구조 및 시공과정을 디지털로 구현한다. 일반적으로 전통건축문화재를 디지털화할 때 건축물의 외형적인 모습에 역점을 두고 제작을 하지만, 본 논문에서는 해당건축물을 해체해야 알 수 있는 눈에 보이지 않는 구조물과 이러한 구조물들이 결합하는 건축 시공순서를 보여줄 수 있도록 수많은 부재를 제작하고 각 위치에 맞게 배치하였다. 본 논문에서는 3D 디지털 근정전을 구현하기 위하여 사용한 Parametric 모델링기법과 Multi-Object Texture Mapping 기법, Physical Camera 와 GI Renderer 설정 그리 고 목조건물의 구조에 대한 전반적인 정보 및 모델링 자료는 다른 목조건축물을 디지털로 제작하는데 활용성이 높다고 할 수 있다.

Segmentation of LiDAR data is an important procedure in building modeling. Therefore, in this study, aerial imagery is used to group LiDAR data for both improving segmentation accuracy and modeling detail surface patches of the roofs. The results show that the proposed method is efficient to analyze and to model various types of roof shape.

건물의 3차원 모델링은 3차원 공간정보를 구축하는데 있어서 매우 중요한 요소이다. 기존의 3차원 건물 모델링은 대부분 항공사진측량기술을 이용하여 수동으로 진행되어 많은 시간과 비용이 소요된다. 이러한 한계를 극복하기 위한 방안으로 최근에는 항공라이다(LiDAR) 데이터를 이용한 건물모델링 방법에 대한 많은 연구가 활발히 진행되고 있다. 항공라이다 데이터를 이용한 대부분의 3차원 건물모델링 연구는 보간과정을 통하여 격자구조로 변환하거나 수치지도 또는 항공영상 등의 이종 데이터간의 융합을 통하여 건물을 모델링하는 방안 등을 제시하였다. 본 논문에서는 점 데이터의 격자구조로의 변환 및 이종 데이터간의 융합 등의 방법을 배제하고 항공라이다 데이터만을 이용한 건물의 자동 모델링 방법을 제안하였다. 건물로 분류된 항공라이다 데이터를 옥트리 분할을 기반으로 3차원 공간상에서 재귀적으로 분할하여 패치(patch)를 구성하고, 동일한 속성을 갖는 패치들을 병합하여 건물의 구성요소를 추출한다. 추출되어진 건물의 구성요소를 대표하는 모델을 생성하여 전체적인 건물의 3차원 모델을 구성한다. 항공라이다 데이터를 이용하여 제안된 방법으로 실험한 결과, 다양한 형태의 건물 모델을 자동으로 구성할 수 있었다.

Building Information Modeling (BIM) has been adopted in variety domain of construction industry. In this circumstances, interest of BIM model quality has been increased. In many countries, automated building code checking system by Industry Foundation Classes (IFC) has been developed and studied to use web based building permission systems. IFC is international standard of BIM format. However, the data structure of IFC does not include all of objects and properties about national building codes. In this paper, we developed the information specification between IFC data structure and national building code to increase interoperability. First, we drew the criteria from literature review to analyze the building code. And then, we analyzed building code and sorted objects and properties for automated building code checking. After that we made mapping table between the sorted data and IFC specification. Using the mapping table, we developed pre-specification about building codes information that does not exist in IFC specification. And the defined information can be used to develop the BIM modeling guide and national building permission system. The pre-specification support increasing the interoperability between user and automated building code checking system. Increasing thee interoperability makes improvement accuracy and reliability about result of automated building code checking.

This paper introduces recent applications of three-dimensional building/construction data modeling (3D) and building information modeling (BIM) to large-scale complex building construction projects in Japan. Recently, BIM has been utilized as a tool in construction process innovation through planning, design, engineering, procurement and construction to establish a front-loading-type design building system. Firstly, the background and introduction processes of 3D and BIM are described to clarify their purposes and scopes of applications. Secondly, 3D and BIM applications for typical large-scale complex building construction projects to improve planning and management efficiency in building construction are presented. Finally, future directions and further research issues with 3D and BIM applications are proposed.

This study is suggest the test system for BIM(Building Information Modeling) qualification. And this study is the field-based BIM educational program with the acquisition of the qualifying certificates. Since field-based BIM and Curriculum(of University and Junior College) are highly linked to the actual practical affairs, the learning connected to the practical affairs out of the teaching focused on BIM modeling would satisfy students, and it would make the acquisition of the certificates which determinate the capability of the practical affairs. Thus teachers should guide students to get the certificates thoroughly, make them understand the importance of the acquisition of the certificates.

건축물 수명주기 동안 생성되는 정보를 통합관리하고 재활용하여 경제적 손실을 줄이고 이윤을 극대화하려는 과정을 Building Information Modeling (BIM)이라고 한다. 기존의 건설관리기법들과 비교하여 양질의 건물을 더 싸게 빠르게 지으려고 한다는 점에서 그 궁극적인 목적이 다르지 않지만, 기존의 기법들이 경영관리기법적인 측면에서 접근하였다면, BIM은 시스템적인 면에서 접근을 하고 있다는 데에 그 차이점이 있다. 본 논문은 BIM의 정의와 배경에 대해서 고찰하고, BIM을 위하여 필요한 핵심기술들의 현재와 미래에 대하여 논의하였다.

In the era of the 4th industrial revolution, smart construction is actively researched, in the domestic construction field, and one of the key elements in this field is Building Information Modeling(BIM). In Korea, smart construction is being implemented through BIM-based digitization and intelligence. The geotechnical engineering field should also prepare for the introduction of BIM. In this study, the concept and application status of GeoBIM were identified, and the direction of future research was presented. This study is a part of the study "Establishment of GeoBIM-based Digital Twin Maintenance System" in the current "Technology Development for Establishment of Jeju Ground Collapse Response System for Safe Road Operation". The subject and scope of the study is continuous excavation at caves located under roads in Jeju Island, and initial research is being conducted on Jaeamcheon-gul and Jeonggusu-gul. This study aims to build a digital twin through individual data construction and integration processes such as cave shape modeling using laser scanners, 3D stratum modeling using borehole information and geophysical exploration data, and modeling of surrounding conditions using drones.
