The hazardous nature of the construction environment and current incident statistics indicate a pressing need for safety performance improvement. One potential approach is the strategic analysis of leading indicators for measuring safety performance as opposed to using only lagging indicators, which has protractedly been the norm. This study presen...
Applications of Building Information Modeling (BIM) have widely infiltrated various construction fields. BIM serves as a set of technologies to maximize productivity, increase collaboration, and improve work efficiency throughout the project life cycle. BIM also supports the best practices of other emerging technologies by creating a platform for i...
Construction site characteristics tend to foster dynamic work environments with a multitude of interactions between moving equipment and pedestrian employees.

•The technology was used to assess multiple variables a...
The cycle time of construction equipment for earthwork operations has a significant impact on project productivity. Elements that directly impact a haul vehicle's cycle time must be identified in order to accurately quantify the haul cycle time and implement strategies to decrease it. The objective of this research is to scientifically identify and...
The construction industry continues to rank as one of the most hazardous work environments. As a result, construction safety remains a critical concern for both practitioners and researchers. Several construction industry members and government agencies have identified a lack in the number of safety personnel within the construction industry. Also,...
The construction industry experiences a disproportionately high number of injuries and fatalities among the total U.S. employed workforce. Although correlations have been identified between physiological information, worker fatigue, and safety, minimal research efforts have collected and analyzed construction-worker physiological metrics. The objec...
Construction site layout planning can be described as a
multi-criteria optimization problem that is traditionally
resolved using two-dimensional project data. Although
construction researchers have investigated construction
site layout methods, few studies have identified methods of
optimization for crane location selection based on safety
and prod...
A typical manufacturing environment is characterized by
a multitude of interactions between pedestrian workers,
equipment and materials. This dynamic work environment
often fosters nonvisible areas that impede a person’s lineof-
sight. The lack of visibility for equipment operators in
manufacturing environments can contribute to struck-by
events th...
The construction work environment remains one of the most hazardous worldwide. As a result of dangerous working environments, construction workers often face safety and health risks throughout the construction process. However, an emphasis on construction safety has increased mainly in the aspect of safety performance, and efforts are required to n...
Renovation of an existing building is an accomplished stem of the construction industry because it supplies financial diversification for construction stakeholders. Although several construction planning tools and stakeholder alignment exercises have been developed, no tool exists to assist project owners to decide between renovating an existing bu...
Many of the greatest catastrophes caused by human error such as Three Mile Island, Chernobyl and Exxon Valdez occurred after extended hours of work when the levels of fatigue among workers were extremely high. Fatigue, which recent research has identified as a principal precursor of many construction accidents, has not been managed well because the...
Construction sites are characterized by rugged outdoor environments, changing site conditions, and dynamic interactions between resources including personnel, equipment, and materials. These harsh environmental conditions and working situations have a unique impact on construction equipment operator’s physiological information. The primary objectiv...
Although the number of fatalities experienced by the U.S. construction industry has been declining, the magnitude of the decrease has stagnated in recent years. Several improvements have been realized in visualizing construction project information through BIM. One improvement in construction safety can be found in the collection, analysis and visu...
