The architecture, engineering, and construction sector requires carbon-intensive materials, such as steel, in the construction process and generates a large amount of waste in the life cycle. This causes global warming and waste problems. The demand for the reuse of construction materials is increasing, although it is not the convention, to reduce the environmental impact. Although the sustainable effect of the reuse of materials has been proven in several studies, materials are not always reuse

Noise barrier tunnels (NBTs) comprise prefabricated components that are easily replaceable, reusable, and have the capacity to improve performance when applied to components as their replacements. Reusing NBTs is more price competitive and environmentally friendly than producing new components. However, determining the remaining life of components before they need to be dismantled, using existing NBTs and their maintenance methods, is a considerable challenge. Therefore, this study used a protot

Economic feasibility and cost analysis in the preliminary planning stage of early-phase construction projects have a significant impact on project management and implementation. However, while estimating the construction cost per unit area, the existing approaches do not account for factors other than the area-related information, causing estimation error. Therefore, a construction cost estimation model that can be utilized in the early phase of a construction project is developed in this study

Design Process Visualization System Intergrating BIM Data and Performance-Oriented Design Information Sung-Ah Kim, Yoon Choe, Myeongho Jang, Wookje Seol Pages 728-733 (2011 Proceedings of the 28th ISARC, Seoul, Korea, ISBN 978-89-954572-4-5, ISSN 2413-5844) Abstract: The essential role of design process visualization is to capture and represent design information as well as the change of design objects to keep track of reasons behind decision-making activities. The most prominent benefit of BIM,

Traditionally, models have been used by designers to represent abstract design ideas or to analyze and evaluate the refined design solutions. The digital model, in particular, represents the logics, process, and intended result of the design in the form of digital information and media. Innovations in Internet of Things (IoT) and 3D printing technologies now enable the various levels of real-world spatial interactions that were possible only when the user becomes an avatar in a cyberspace. This

Objectives: This study was conducted to evaluate factors related to the intention of participation in a worksite smoking cessation program. Methods: To explain the health behavior of participating intention in a worksite smoking cessation program, the health belief model(HBM) was used as study model, and 144 self-administered questionnaires were completed by electronic company workers. Variables of the health belief model were composed of perceived susceptibility to smokinginduced disease, perce

The utilization of artificial intelligence (AI) in daylight analysis has recently experienced an increase. Its capabilities have been demonstrated through different studies. While using AI for daytime simulation can reduce time, it also presents significant challenges. Whether we utilize the conventional approach of simulating daylight or employ artificial intelligence, the process of going from hand drawing to obtaining the daylight analysis result involves intricate procedures associated with

One of the most critical challenges for architects in façade design is providing an effective view from the indoors to the outdoors of a building for users, although the main role of the parametric façade is covering openings to control daylight and temperature. This study uses a genetic algorithm to optimize and evaluate the number and place of nodes and the position of supports required for a parametric façade based on the geometric patterns. Using the dataset with genetic algorithms is effect

Noise barrier tunnels (NBTs) are road facilities installed to reduce road traffic noise. Although building information modeling (BIM) has been widely used in civil engineering, alignment problems must first be addressed for BIM to be applied in transportation infrastructure; this is because unlike buildings, roads are linear. The array of tunnel frames based on the centerlines of individual roads cause the discontinuity of components at junctions of two NBTs. This leads to structural instabiliti
