Measuring Workers’ Emotional State during Construction Tasks Using Wearable EEG
(American Society of Civil Engineers, 2018)Construction workers’ emotional states (e.g., pleasure, displeasure, excitement, and relaxation) are known as a critical factor that affect their performance (e.g., safety, health, and productivity). To prevent ... -
Constraint Programming Approach to Optimizing Project Schedules under Material Logistics and Crew Availability Constraints
(American Society of Civil Engineers, 2018)With increasing implementation of off-site prefabrication and modular construction technologies, the complexity of material supply chain management on construction projects has grown substantially. However, research on ... -
Key Moderators of the Relationship between Construction Crew Motivation and Performance
(American Society of Civil Engineers, 2018)Construction crew performance is a function of both motivation and the situation in which tasks are performed. However, previous research in construction has not comprehensively investigated situational/contextual factors ... -
Image-and-Skeleton-Based Parameterized Approach to Real-Time Identification of Construction Workers’ Unsafe Behaviors
(American Society of Civil Engineers, 2018)Workers’ unsafe behaviors are one of the main causes for construction accidents. Fully understanding the causes of unsafe behaviors on site will help to prevent them, thus reducing construction accidents. The accurate and ... -
Characteristics and Evolution of Innovative Collaboration Networks in Architecture, Engineering, and Construction: Study of National Prize-Winning Projects in China
(American Society of Civil Engineers, 2018)As the scale and complexity of capital projects continue to increase, so do collaboration requirements among owners, engineers, architects, contractors, and other stakeholders in the project lifecycle. These organizational ... -
Legalized Recreational Marijuana: Safety, Ethical, and Legal Perceptions of the Workforce
(American Society of Civil Engineers, 2018)Recreational drug use in construction is an area of concern for safety managers, and the legalization of marijuana in several US states may result in increased use among workers. Experimental approaches and policy creation ... -
Stability Analysis of Two Parallel Closely Spaced Tunnels Based on Convergence–Confinement Principle
(American Society of Civil Engineers, 2018)Stability analysis and risk assessment are key issues in the design and construction of tunnels; however, these assessments are often hard to conduct accurately because of the complexity of tunnel engineering. In order to ... -
Cluster Analysis of Risk Factors from Near-Miss and Accident Reports in Tunneling Excavation
(American Society of Civil Engineers, 2018)Many inherently risky industries improve their safety management by learning from near-miss incidents. The construction industry is starting to manage near-miss incidents for improving safety, and several studies have been ... -
Comparing the Random Forest with the Generalized Additive Model to Evaluate the Impacts of Outdoor Ambient Environmental Factors on Scaffolding Construction Productivity
(American Society of Civil Engineers, 2018)The improvement of construction productivity has always been a key concern for both researchers and project managers. Several studies have analyzed construction productivity from different perspectives; however, little ... -
Three-Variance Approach for Updating Earned Value Management
(American Society of Civil Engineers, 2018)The project management triad consists of scope, time, and cost. In this study, the schedule variance and schedule performance index, in traditional two-variance earned value management (EVM), are proven not proper time ... -
Extended Technology-Acceptance Model to Make Smart Construction Systems Successful
(American Society of Civil Engineers, 2018)Research and development (R&D) of smart construction systems has been constrained by the contentious relationship between system developers and potential industry users. System developers are critical of practitioners’ ... -
Untitled
(American Society of Civil Engineers, 2018)Uncertainty and risks have been the inherent characteristics of large-scale projects. Although practitioners have applied different project risk management standards, numerous uncertainties, and risks in large-scale ... -
Model of Equipment Sharing between Contractors on Construction Projects
(American Society of Civil Engineers, 2018)Because of significant characteristics such as complexity and uncertainty, the construction schedules of large-scale projects are often postponed as a result of a shortage of important equipment. By sharing its own incentive ... -
Impact of CIM Technologies and Agency Policies on Performance for Highway Infrastructure Projects
(American Society of Civil Engineers, 2018)The digital tools and practices that facilitate the collection, organization, and use of accurate data and information throughout the life cycle of a highway infrastructure asset are referred to as civil integrated management ... -
Novel Precast Erection Method of Interlocking Mechanical Joints Using Couplers
(American Society of Civil Engineers, 2018)Despite many advantages of precast concrete members, the conventional precast members lack in the treatment of construction waste, require concrete pour forms at joints, and their structural discontinuity leads to low ... -
Environmental Product Declarations: Use in the Architectural and Engineering Design Process to Support Sustainable Construction
(American Society of Civil Engineers, 2018)High-performing and sustainable building certification bodies continue to update their requirements, leading to modifications in the scope of certifications and increasing the number of viable sources of environmental ... -
Construction Noise Risk Assessment Model Focusing on Construction Equipment
(American Society of Civil Engineers, 2018)Environmental issues are becoming a growing concern for the construction sector and cause a number of complaints. Construction noise is one of the most prevalent stressors to the public, especially for residents near ... -
Developing More Competitive Proposals: Relationship between Contractor Qualifications-Based Proposal Content and Owner Evaluation Scores
(American Society of Civil Engineers, 2018)Construction contractors have historically been procured through price-driven methods. Yet the increased use of alternate project delivery methods, along with owner-perceived concerns over construction performance, has led ... -
