Measuring and Predicting Fatigue in Construction: Empirical Field Study
(American Society of Civil Engineers, 2018)The increasing commitment to safety over the last two decades has contributed to a 67% decline in recordable incident rates. The rate of fatalities, however, has recently increased. Human factors, like fatigue, strongly ... -
Matching Construction Workers across Views for Automated 3D Vision Tracking On-Site
(American Society of Civil Engineers, 2018)Computer vision–based tracking methods are used to track construction resources for productivity and safety purposes. This type of tracking requires that targets be accurately matched across multiple camera views to obtain ... -
Impact of Skilled Labor Availability on Construction Project Cost Performance
(American Society of Civil Engineers, 2018)The North American construction industry began to experience a shortage of skilled labor in the 198s, which has continued as a repetitive cyclic trend over the last three decades. Although this issue has received significant ... -
Long-Run Construction Cost Trends: Baumol’s Cost Disease and a Disaggregate Look at Building Material Price Dynamics
(American Society of Civil Engineers, 2018)Decision-support tools for infrastructure planning assume that the real cost of construction (i.e., the cost of construction when adjusting for inflation) will remain constant over the life cycle of a facility. This ... -
Improving Workplace Hazard Identification Performance Using Data Mining
(American Society of Civil Engineers, 2018)Hazard identification, as the first major step of risk management, is a crucial activity for reducing accidents and other related losses. However, recent research has revealed that a large proportion of workplace hazards ... -
Measuring and Evaluating Safety Maturity of Construction Contractors: Multicriteria Decision-Making Approach
(American Society of Civil Engineers, 2018)Evaluating the safety maturity of construction contractors before awarding the contract is an effective strategy that many owners have started to implement. Given the importance of workplace safety, awarding the contract ... -
Value Engineering for Defect Prevention on Building Façade
(American Society of Civil Engineers, 2018)A building façade is affected by the environment as well as the physical performances of the building-materials at every stage of the building’s life cycle. Although a number of studies have been conducted to overcome the ... -
4D-BIM Dynamic Time–Space Conflict Detection and Quantification System for Building Construction Projects
(American Society of Civil Engineers, 2018)Workspace in construction projects is considered a resource and a constraint that needs to be addressed in project scheduling. Without proper workspace planning, time–space conflicts frequently may occur at construction ... -
Assessing the Influence of Virtuality on the Effectiveness of Engineering Project Networks: “Big Five Theory” Perspective
(American Society of Civil Engineers, 2018)Engineering project networks (EPNs), as digitally mediated units whose team members are scattered across different organizations/locations, have become the norm for construction project teams. In EPNs, virtuality captures ... -
Analysis of Citation Networks in Building Information Modeling Research
(American Society of Civil Engineers, 2018)Building information modeling (BIM) has emerged as a pervasive and ubiquitous tool in the fields of construction and engineering. With BIM’s rise, so too has there been an explosion of research interest in BIM. Nevertheless, ... -
Hybrid Genetic Algorithm and Linear Programming for Bulldozer Emissions and Fuel-Consumption Management Using Continuously Variable Transmission
(American Society of Civil Engineers, 2018)This paper develops a hybrid optimization approach combining genetic algorithm (GA) and integer linear programming (ILP) to solve the nonlinear optimization problem of managing the fuel consumption and emissions of a tracked ... -
Exploring Relationships between National Culture and Infrastructure Sustainability Using QCA
(American Society of Civil Engineers, 2018)Cultural factors are unavoidable in the infrastructure construction process, and understanding relationships between culture and infrastructure sustainability (IS) will help increase IS levels. A qualitative comparative ... -
Revisiting Quality Failure Costs in Construction
(American Society of Civil Engineers, 2018)Quality failure costs have been reported to range from less than 1 to over 20% of a project’s original contract’s value (OCV). Inconsistencies in their definition and determination have rendered such costs often being cited ... -
CoVR: Cloud-Based Multiuser Virtual Reality Headset System for Project Communication of Remote Users
(American Society of Civil Engineers, 2018)Inefficient communication among project stakeholders is one of the most critical issues in the architecture, engineering, and construction (AEC) industry. In reality, it is difficult to create a common understanding about ... -
Ontology-Based Knowledge Model to Support Construction Noise Control in China
(American Society of Civil Engineers, 2018)Construction noise control (CNC) is the process of identifying potential noise emissions and establishing noise-abatement plans to mitigate pollution impacts, a process that requires interdisciplinary knowledge and ... -
Geometry- and Appearance-Based Reasoning of Construction Progress Monitoring
(American Society of Civil Engineers, 2018)Although adherence to project schedules and budgets is most highly valued by project owners, more than 53% of typical construction projects are behind schedule and more than 66% suffer from cost overruns, partly because ... -
Influence of Simplified Procurement Methods on Competition for Public Sector Construction
(American Society of Civil Engineers, 2018)In response to problems of cumbersome regulations and understaffed public agencies, governments have worked to simplify procurement statutes and streamline processes. One of the most widely used simplified processes in the ... -
Optimized AHP to Overcome Limits in Weight Calculation: Building Performance Application
(American Society of Civil Engineers, 2018)Multicriteria decision making methods, in particular the analytic hierarchy process (AHP), are widely used in many sectors, and increasingly in the field of construction. The AHP is easily adaptable to many decision problems, ... -
An Empirically Based Agent-Based Model of the Sociocognitive Process of Construction Workers’ Safety Behavior
(American Society of Civil Engineers, 2018)Workers’ unsafe behaviors have a substantial impact on construction safety. To regulate workers’ unsafe behavior, construction practitioners have mainly used formal controls (e.g., penalties). However, the formal ... -
Risk Behavior-Based Trajectory Prediction for Construction Site Safety Monitoring
(American Society of Civil Engineers, 2018)Construction sites are often described as some of the most hazardous work environments due to the unscripted nature of tasks which puts workers and equipment in close proximity, potentially resulting in near-miss situations ...
