RISRevealing the Impact of Heat Radiation on Construction: A Microclimate Simulation Using Meteorological Data and Geometric Modeling
Publisher: ASCE
Abstract: The construction industry is vulnerable to heat-related hazards, necessitating identification of high-risk areas and contributing factors. This study introduces a novel framework that integrates microclimate simulations ...
Paradox of Time Pressure: Cognitive and Task Performance during Time-Sensitive and Challenging Teleoperation
Publisher: American Society of Civil Engineers
Abstract: A heavy machinery operators’ ability to adhere to schedules is crucial for the success of construction projects. However, unforeseen delays often occur during projects, forcing operators to expedite their work. This pressure ...
Participatory Sensing and Digital Twin City: Updating Virtual City Models for Enhanced Risk-Informed Decision-Making
Publisher: ASCE
Abstract: The benefits of a digital twin city have been assessed based on real-time data collected from preinstalled Internet of Things (IoT) sensors (e.g., traffic, energy use, air pollution, water quality) for managing the ...
Increasing Reliability of Participatory Sensing for Utility Pole Condition Assessment Using Fuzzy Inference
Publisher: ASCE
Abstract: Aging infrastructure has become a safety issue for local communities. For example, aging and deteriorating utility poles in strong winds have a high risk of falling onto roads, adjacent houses, or vehicles, which could ...
Three-Dimensional Thermography-Based Method for Cost-Benefit Analysis of Energy Efficiency Building Envelope Retrofits
Publisher: American Society of Civil Engineers
Abstract: Recent research efforts to improve energy modeling and diagnostics for existing buildings have focused on devising methods based on digital photogrammetry or three-dimensional (3D) laser scanning and thermal imagery. Prior ...
Automated Diagnostics and Visualization of Potential Energy Performance Problems in Existing Buildings Using Energy Performance Augmented Reality Models
Publisher: American Society of Civil Engineers
Abstract: Quick and reliable identification of energy performance problems in buildings is a critical step in improving their efficiency. The current practice of building diagnostics typically involves nonintrusive data collection ...
System-Level Approach for Identifying Main Uncertainty Sources in Pavement Construction Life-Cycle Assessment for Quantifying Environmental Impacts
Publisher: American Society of Civil Engineers
Abstract: Poor data quality in pavement construction life-cycle inventory (LCI) causes uncertainty in quantifying the associated environmental impact through life-cycle assessment (LCA). To reduce such LCA uncertainty while enhancing ...
Impact of Demand-Side Response on Community Resilience: Focusing on a Power Grid after Seismic Hazards
Publisher: ASCE
Abstract: The performance of a power grid after a disaster is associated with the grid’s ability to meet electricity demand under supply disruption. Prior studies primarily focused on reducing risk through reinforcement of supply-side ...
Effective Risk Positioning through Automated Identification of Missing Contract Conditions from the Contractor’s Perspective Based on FIDIC Contract Cases
Publisher: ASCE
Abstract: Defining, measuring, and dealing with contractual risks are crucial for successful construction projects because the contractual risks can lead to serious claims and disputes. In general, construction participants make a ...
Analyzing Safety Risk Imposed by Jobsite Debris to Nearby Built Environments Using Geometric Digital Twins and Vision-Based Deep Learning
Publisher: ASCE
Abstract: Extreme wind events can pick up loose and small objects on the ground, and once the objects become airborne, they negatively impact surrounding communities due to the collision impact. In this regard, jobsites and laydown ...
