Recent technological improvements have made substantial changes in construction industry. In specific, some technical applications, such as Building Information Modeling (BIM), open up many possibilities. Some studies have articulated the use of BIM and its advantages in construction, but most of them are theoretical, not practical. This study is to provide an insight to obstacles in BIM research. By investigating a real project that could utilize BIM in planning and construction phases, the aut

Building information modeling (BIM) has opened up many possibilities for the construction industry. However, most studies focus mainly on its overall uses and management areas. By investigating real projects that could utilize BIM in the design phases for railway construction, the authors examine the possible advantages and disadvantages in BIM implementation. To do so, the authors have selected three projects that utilized BIM implementation during the design process and three other projects wi

A tropical storm Chaba hit the southeastern part of South Korea in 2016. Ulsan, the 8th largest city in terms of the number of population, was especially damaged with heavy flooding, and the calculated damage was approximately $500 million. By using Normalized Differences in Vegetation Index (NDVI), four districts and 46 sub-districts in Ulsan city, South Korea. Analysis results indicate that having a higher proportion of green space inside a city could have a reduction effect on flooding risks.

The authors provide a holistic perspective to enhance BIM working environment for more efficient smart construction settlements. An in-depth survey with 40 questionnaires was distributed to 100 professionals in construction, design, engineering, government. Although 45% of the respondents have received a certain form of BIM education, more than 94% of the respondents have answered that there should be a formal BIM education. Both design and construction experts have reported that the biggest adv

Challenges caused by the care of the ageing population in many countries are becoming increasingly severe. However, high expenditures on healthcare services and the cost of infrastructure construction will be an unbearable burden for both the government and individuals. Due to its security, convenience, and lower prices compared with traditional medical care, smart home technology, which includes information and communication technologies (ICTs), artificial intelligence (AI), and the Internet of

In response to the challenge of atmospheric pollution posed by growing environmental problems, this study reviews and analyzes the research status and development trends of green infrastructure (GI) in improving air pollution from 2014 to 2024. Using the CiteSpace tool, we explore research hotspots, disciplinary developments, significant contributors, and influential literature in this field, identifying current research gaps and predicting future trends. The findings indicate that GI significan

Building information modeling (BIM) is acknowledged for enhancing efficiency and collaboration in the construction industry. However, its application in the construction phase of railway projects faces challenges. This study, utilizing quantitative and qualitative analyses, explores the advantage of BIM consulting services in the railway infrastructure projects. A comparative analysis of similar-scale projects shows that BIM significantly boosts construction efficiency, yielding a 197.6% economi

This study addresses sustainable transportation in the Texas Urban Triangle at the regional scale. Its aim is to determine the most suitable corridor for new transport infrastructure by employing a spatial decision support system proposed in this project. The system is being tested through its application to a prototype corridor parallel to Interstate 35 between San Antonio and Austin. The basic research questions asked are spatial in nature, so accordingly the geographic information system is t

This project addressed sustainable transportation in the Texas Urban Triangle (TUT) by conducting a pilot project at the county scale. The project tested and developed the multi-attribute Spatial Decision Support System (SDSS) developed in 2009 under a previous UTCM project (TRID Online Accession #01324956), in order to determine the most suitable locations for transportation infrastructure networks, including high-speed rail. The research team selected a key county in the Austin-San Antonio seg

If we had estimated the ecological consumptions of rapid growth from the beginning and considered $2076/person for environmental opportunity costs, then the development patterns and other associated urban planning agendas would have shifted accordingly to increase the overall sustainability. Like most developing cities in the world, major cities in South Korea and the central government concentrated its main strategy on economic growth. Doing so stimulated national economy and made it possible t
