In the construction industry, there has been a surge in the implementation of high-tech equipment in recent years. Various technologies are being considered as potential solutions for future construction projects. Building information modeling (BIM), which utilizes advanced equipment, is a promising solution among these technologies. The need for safety inspection has also increased with the aging structures. Nevertheless, traditional safety inspection technology falls short of meeting this demand as it heavily relies on the subjective opinions of workers. This inadequacy highlights the need for advancements in existing maintenance technology. Research on building safety inspection using 3D laser scanners has notably increased. Laser scanners that use light detection and ranging (LiDAR) can quickly and accurately acquire producing information, which can be realized through reverse engineering by modeling point cloud data. This study introduces an innovative evaluation system for building safety using a 3D laser scanner. The system was used to assess the safety of an existing three-story building by implementing a reverse engineering technique. The 3D digital data are obtained from the scanner to detect defects and deflections in and outside the building and to create an as-built BIM. Subsequently, the as-built structural model of the building was generated using the reverse engineering approach and used for structural analysis. The acquired information, including deformations and dimensions, is compared with the expected values to evaluate the effectiveness of the proposed technique.

The purpose of this research is to analyze a case study of the applicability of BIM concept in architectural engineering design education of 4-year architectural engineering program under ABEEK accreditation. The research method is to introduce a case of architectural engineering design studio and to compare the satisfaction of outcome between BIM S/W and conventional design process. The survey outcome reveals that the satisfaction of BIM S/W is relatively higher than the satisfaction of drawings by hands. The design education outcome is analyzed according the characteristics of expression, revision, relationship, and spatial understanding, etc.

Public institutions and owners have been introduced to use Building Information Modeling (BIM) tools. Learning BIM becomes an important factor in design process of undergrad program. The purpose of this study is to demonstrate an integrated architectural engineering design process using BIM tools. BIM education programs are analyzed to compare the level of detail in BIM education. An architectural engineering design class needs to involve BIM to introduce integrated process. An architectural engineering design process needs be based on understanding design, building structure, construction and building services. 3D Modeling helps understanding a building structure and checking environment-friendly element analysis. As a result of this research, new process of design education is proposed under four issues.

소류지의 주변으로 농축산농가와 마을 등이 위치할 경우 지속적인 오염물질 유입과 강우시 농경지등에서 발생하는 비점오염물질 유입 등으로 부영양화의 원인이 되고 있으며, 이로 인해 식물성 플랑크톤의 이상번식으로 부영양화가 악화되고 있는 실정이다. 이에 본 연구에서는 태양전지 물순환장치를 이용하여 부영양화 저감효과를 평가하고자 한다. 소류지내에 태양전지 물순환장치를 설치 후 식물성 플랑크톤과 부영양화지수를 평가한 결과. 전체 식물성 플랑크톤 현존량의 경우 큰 변화가 나타나지 않았으나, 부영양화의 주요인 중 하나인 남조류가 제어되었으며, 부영양화지수는 가동기간이 증가함에 따라 부영양화지수가 감소하는 것으로 나타나 부영양화 방지에 있어서 효과적이라 판단된다.

To consider the practicality and economic feasibility of developing reactive powder concrete (RPC), the strength and microstructure properties of RPC using ternary pozzolanic materials (silica fume, blast furnace slag, fly ash) were investigated in this study. Through the investigation, it was found that the compressive strength of RPC using ternary pozzolanic materials was increased significantly compared to that of the original RPC containing silica fume only. A considerable improvement in the flexural strength of RPC using ternary pozzolanic materials was found, and then the utilization of a structural member subjected to bending was expected. The X-ray diffractometer (XRD) analysis and Scanning Electronic Microscope (SEM) revealed that the microstructure of RPC was denser using the ternary pozzolanic materials than the original RPC.

With domestic construction projects becoming bigger, more specialized and more advanced, the construction industry is striving to improve quality and quantity, and is diversifying functions and shapes. Nevertheless, the process of a construction project causes problems when we estimate construction price, because the cost breakdown structures are different in each step. The primary aim of this study was to estimate building life cycle cost using the Delphi method. The cost breakdown structure for life cycle cost was classified into planning, design, construction, maintenance and waste disposal, and each detailed classification was determined by estimating life cycle cost. Moreover, the developed cost breakdown structure is verified by consulting with experts to secure objectivity and validity.
