Defect Risk Assessment Using a Hybrid Machine Learning Method
(ASCE, 9/1/2020 1)Defects pose considerable risks to construction projects in terms of both cost and quality, and identifying defects thus is crucial to effective construction quality management. In this study, data for 45 cases were obtained ... -
Revisiting Project Delivery System Performance from 1998 to 2018
(ASCE, 9/1/2020 1)This paper presents the results of a study to compare the performance of design-bid-build (DBB), construction manager at risk (CMR), and design-build (DB) project delivery systems in the US building construction industry. ... -
Dynamic Network Analysis of Stakeholder Conflicts in Megaprojects: Sixteen-Year Case of Hong Kong-Zhuhai-Macao Bridge
(ASCE, 9/1/2020 1)Stakeholder conflicts are hard to avoid in the implementation of megaprojects due to the diverse interests and aims among stakeholders. The previous study does not provide much evidence on dynamic patterns of stakeholder ... -
Detection of Railway Masts in Airborne LiDAR Data
(ASCE, 9/1/2020 1)Generating an object-oriented, geometric digital twin of an existing railway from its point cloud data (PCD) is a laborious task, needing 10 times more labor hours than scanning the physical asset. The resulting modeling ... -
Novel Probabilistic Cost Estimation Model Integrating Risk Allocation and Claim in Hydropower Project
(ASCE, 8/1/2020 1)The uncertain construction of hydropower projects and fierce market competition put forward more stringent requirements for contractors with regard to accuracy and competitiveness of cost estimation. However, previous ... -
Attaining Successful Construction Project Execution Through Personnel and Communication
(ASCE, 9/1/2020 1)Prior research has disagreed on the definition of construction project success and the best way to achieve it. Additionally, there is very little research that takes a practitioner’s viewpoint and provides findings useful ... -
Construction Automation and Robotics for High-Rise Buildings: Development Priorities and Key Challenges
(ASCE, 8/1/2020 1)Construction automation and robotics have been researched and developed over the last three decades. Although the practical needs keep rising, the on-site application rate remains limited. Therefore, this study aims to ... -
Comparison of Worker Safety Risks between Onsite and Offsite Construction Methods: A Site Management Perspective
(ASCE, 9/1/2020 1)Many researchers, as well as industry practitioners, believe that offsite construction methods are associated with a lower level of worker safety risks than traditional onsite construction methods. This study aims to test ... -
Analysis of Relationships between Body Load and Training, Work Methods, and Work Rate: Overcoming the Novice Mason’s Risk Hump
(ASCE, 8/1/2020 1)Masons regularly perform physically strenuous and demanding duties that may exceed a safe limit. Such activities can contribute to an early retirement for masons, resulting in a shortage of skilled craft workers. Previous ... -
Cost Impacts of Change Orders due to Unforeseen Existing Conditions in Building Renovation Projects
(ASCE, 8/1/2020 1)A renovation project generally requires time, money, or costly equipment to examine the existing conditions of a structure. When unforeseen existing conditions are not properly examined, unexpected costs and/or schedule ... -
Determining the Relationship between Direct Work and Construction Labor Productivity in North America: Four Decades of Insights
(ASCE, 9/1/2020 1)Labor productivity in construction has fallen behind other industries in most of the world and has declined continuously for decades in the United States. To change this, the construction industry needs to know where to ... -
Formulating Systemic Construction Productivity Enhancement Strategies
(ASCE, 8/1/2020 1)Studies that have measured construction productivity, analyzed its influencing parameters, and explored enhancement strategies abound in the literature. However, few have quantified the relationship between the total factor ... -
Data-Driven Framework for Modeling Productivity of Closed-Circuit Television Recording Process for Sewer Pipes
(ASCE, 8/1/2020 1)Closed-circuit television (CCTV) is widely used in North America for sewer pipe inspection due to several benefits, such as easy operation and lower upfront costs. To be useful, video footage needs to be collected according ... -
Eye-Tracking Experimental Study Investigating the Influence Factors of Construction Safety Hazard Recognition
(ASCE, 8/1/2020 1)Construction site accidents can be reduced if hazards leading to accidents are correctly and promptly detected by employees. Proactive safety measures such as safety perception and safety detection capability of employees ... -
4D-Based Workspace Conflict Detection in Prefabricated Building Constructions
(ASCE, 9/1/2020 1)A number of parallel lifting operations may take place simultaneously on a prefabricated construction site, likely resulting in workspace overlapping, which is likely to delay the project and even cause accidents. This ... -
Simulation-Based Lift Planning Model for the Lift Transfer Operation System
(ASCE, 9/1/2020 1)Producing adequate lift plans for a transfer operation system (TOS) used in irregularly shaped high-rise building constructions is a more complex task than for an all-floor lift operation system. In the TOS, a resource ... -
Impact of Supervisory Safety Communication on Safety Climate and Behavior in Construction Workgroups
(ASCE, 8/1/2020 1)In industries in which organizations work in decentralized and distributed structures such as construction, workers are more likely to be influenced by their workgroup supervisors than upper-level management. A study was ... -
