Fire safety engineering is a critical specialization to include in the design of a tall building yet is often excluded from the Building Information Model (BIM) and integrated design process. The design of fire safety systems is interdependent with building/structural geometry, HVAC, mechanical, and electrical systems. A BIM is a 3D visual representation that stores data on these kinds of systems. The compatibility between BIM and fire safety design seems obvious yet has received a dearth of attention in structural (fire) engineering literature. The authors herein have reviewed over 40 recent papers on utilizing BIM for fire safety engineering, focusing on contemporary literature to obtain a more up-to-date review of the state-of-the-art. The resulting trends, technologies, research gaps, and methodologies are presented in this paper. Adoption of BIM in fire safety engineering is slow and behind other disciplines which may be improved if research involved more industry partners. For BIM technology to reach its potential, industry manufacturers need to provide high LOD fire BIM objects, fire engineers and researchers need to collaborate on future advancements, and building owners/management need to be educated on how to use the benefits provided.

Roof structure of the traditional buildings in the Northeast Asia region including Korea contains the most complicated and crucial components of the building and therefore the issues such as cost down, productivity and the attempt to combine the traditional building methodology with contemporary building technology turn out to be vital to the survival of the old yet disconnected traditional building industry. One of the distinctive modern building technologies is handling life-cycle building information by constructing virtual buildings using BIM, building information modeling tools. In this paper we follow a procedure to implement some of the design modules to be applied in BIM tools which are platforms for constructing virtual building models. We focus on Gong-po components namely the bracket-sets which are the essential part that connects the middle parts to the top parts (the roof structure) which are considered to be the most elaborate parts of the traditional buildings. The target building to work with in this paper is the Sung-Rye-Moon which has special cultural and social meanings nowadays and we tested our understanding and the design modules such as the bracket-sets by constructing a virtual building model of Sung-Rye-Moon.

It seems obvious that the spatial information of existing architectural heritage will be re-structured utilizing BIM technology. In the future to be able to implement such task, a new system of classification of spatial information, which fit to the structural nature of architectural heritage is necessary. This paper intend to suggest the conceptual model that can be the base of establishing new classification system for architectural heritage. For this study we reviewed researches related to classification system of architectural heritage (CS-AH) and BIM based architectural heritage (BIM-AH), first. As a result, we found that CS-AH is focused on building elevation and type, and BIM-AH is biased on the Library and Parametric Modeling. Second, we figured out a relationship between the CS-AH and BIM-AH. From this analysis, we found that BIM-AH is biased on Library and Parametric since the building elevation and type was focused on CS-AH. This review suggests a potential of the 3D CS-AH to expand the range of research for BIM-AH. At last, we suggest the three concept of classification are: 1)horizontality-accumulation relationship, 2)structure-infill relationship, 3)segment-member relationship. These three concept, together as one system of classification, could provide useful framework of new classification system of spatial information for architectural heritage.

건설프로젝트 관리 과정에는 수많은 정보가 존재한다. BIM(Building Information Modelling)은 정보전달의 매개체로써 공정 및 원가 정보를 관리하여 4D(3D+Time), 5D(4D+Cost) 시뮬레이션 등 다양한 이익을 얻을 것으로 예상되었다. 그러나 BIM 활용과정에 따른 정보의 연계 문제, BIM 객체기반 공정/원가 정보의 한계, BIM 소프트웨어 호환성 문제 등으로 인해 BIM을 활용한 공정 및 원가정보의 관리는 적극적으로 활용되지 못하고 있다. 이에 본 연구에서는 위의 문제점들을 개선하고자 IFC(Industry Foundation Classes)활용 BIM기반 공정/원가 통합관리 프레임워크를 제안하였다. 먼저, 정보 입력 문제와 정보 표현의 한계점을 개선하기 위해 공간을 최소단위로 공정 및 원가정보를 통합 관리하는 데이터베이스를 구축하고, 데이터 호환성 문제를 해결하기 위해 국제 표준 데이터 포맷인 IFC를 활용하여 앞서 구축한 데이터베이스의 정보와 BIM 소프트웨어를 연계하여 BIM을 기반으로 한 공정/원가 정보의 통합관리를 시도하였다. 이는 BIM기반 공정/원가 통합관리를 위한 정보 처리 프로세스의 기초를 제공하며, 정보 요구에 대한 정확한 이해를 도와 의사소통의 정확성을 향상시켜 BIM기반 공정/원가관리의 효율성을 높일 것으로 예상된다.

Existing BIM(Building Information Modeling) based energy evaluation tools cannot be utilized enough for the potential performance of BIM because most of them have not provided the integrated model for energy evaluation, assessment of the material, cost of the construction, and so on. This research aims to propose and develop a new application, EcoBIM, to support an integrated evaluation of the energy and cost efficiencies of the design alternatives within the design process. The proposed application functions as a BIM-based evaluation system that calculates energy-savings performance as well as the construction cost of the alternatives at the design stage. This study mainly focuses on the possibilities of developing the proposed technology. We also suggest an advanced design process using the proposed system, corresponding to changes of national regulations in Korea. This study deduce that EcoBIM can allow architects to make suitable decisions regarding energy- and cost-efficient designs. The proposed design process will allow architects not only to check the eco-friendly performance of design alternatives but also predict the operation cost in a certain period in the future. EcoBIM can prevent large-scale design changes required to obtain environmental certification and enable the owner to make an informed decision about the initial investment of construction according to the result of the analysis of the energy requirement at the design stage.
