Fall accidents constitute a crucial type of accident in the construction industry. This study investigates fall accidents that occurred in the United States between 1997 and 2012. Using the 20,997 construction industry accidents recorded in the Occupational Safety and Health Administration (OSHA) database, this study examines the frequency and trend of fall accidents. Additionally, by using data from 9,141 fall accidents, this study investigates various dimensions of fall accidents, such as fall

The importance of green buildings has been frequently highlighted. However, barriers such as greater complexity, lack of understanding of sustainability, and the perception of a greater possibility of cost overrun have hindered the dissemination of green buildings. More planning efforts for green buildings can presumably help mitigate these barriers. This paper investigates preproject planning efforts for green and conventional building projects. Project-level data were collected (124 in total,

This paper evaluates the use of information technology (IT) and its impact on project and company performance in the construction industry. Using project level data from 139 projects and company level data from 74 companies, the current state of IT use in the construction industry was studied and statistical analyses were performed to assess the correlation between IT use and performance. Analyses are segregated by owner and contractor stakeholder groups and findings suggest that more IT use cor

The Internet of Things (IoT) has attracted attention in recent years as a way to prevent construction site accidents. Although various IoT technologies have been tested for the purpose of safety management, few have been implemented in actual projects. One possible reason is that the effectiveness of these technologies has rarely been calculated. In this study, a method for quantitatively evaluating the effectiveness of IoT technologies for accident prevention is presented. Taking the domino the

The lack of fall protection has been the most frequently cited Occupational Safety and Health Administration (OSHA) standard in the US construction industry. This article investigates the use of fall protection in the US construction industry over the past two decades. Using fall accidents data between 1997 and 2012 from the OSHA Integrated Management Information System (IMIS), the use of fall protection, categorized into three classes (correct use, misuse, and no fall protection), was studied w

The purpose of this study is to investigate performance indicators to measure the effectiveness of claim management for construction projects. As current construction projects become larger and more complex, claim management becomes more diverse and essential for the success of the project. Although claim management has been the subject of many previous studies, few studies have investigated the performance indicators for claim management. By interviewing 21 industry practitioners from 10 compan

This paper introduces a two-step subcontracting process for building information modeling (BIM)–based design coordination under a design-bid-build (DBB) contract. Although integrated project delivery (IPD) is known to be an ideal contractual method for BIM projects, DBB still has been the dominant contracting method, owing to the complexity of IPD, as well as regional regulations. BIM-based design coordination under DBB can effectively reduce design errors through the value engineering process.

Building from considerable empirical research in the general business literature, this paper quantitatively explores the view that the benefits of information technologies manifest themselves through improvement in work processes. In turn, better work processes lead to increased project performance. Using an overall sample of 133 projects (missing data make specific correlation sample sizes smaller) from the Construction Industry Institute Benchmarking and Metrics database, this paper analyzes c

The importance of construction industries has increased significantly in developing countries because of rapid urbanization. Lack of construction management (CM) skills is one of the main risks for project stakeholders in developing countries. Therefore, developing countries need to create training programs and establish laws and regulations to enhance CM skills. As CM has many functions, it is necessary to prioritize them appropriately. In this study, a survey of practitioners in the Cambodian
