RISMultiagent Approach for Real-Time Collision Avoidance and Path Replanning for Cranes
Publisher: American Society of Civil Engineers
Abstract: Collisions on construction sites are one of the primary causes of fatal accidents. This paper proposes a multiagent-based approach to provide real-time support to the staff of construction projects. Collision avoidance is ...
Review and Survey of 4D Simulation Applications in Forensic Investigation of Delay Claims in Construction Projects
Publisher: ASCE
Abstract: Four-dimensional (4D) simulation is not frequently used in courtrooms because it is considered costly, complex, and risky. The experience in litigation systems reveals that many expert witnesses at present are not familiar ...
Integrating Variance Reduction Techniques and Parallel Computing in Construction Simulation Optimization
Publisher: American Society of Civil Engineers
Abstract: Efficient planning of construction operations is deemed necessary to meet project objectives. Researchers have used simulation optimization to select the optimum amount of equipment and number of crews for construction ...
Two-Dimensional and Three-Dimensional CNN-Based Simultaneous Detection and Activity Classification of Construction Workers
Publisher: ASCE
Abstract: The type and duration of construction workers’ activities are useful information for project management purposes. Therefore, several studies have used surveillance cameras and computer vision to automate the time-consuming ...
Ontology for Linking Delay Claims with 4D Simulation to Analyze Effects-Causes and Responsibilities
Publisher: ASCE
Abstract: Visualizing and analyzing the specifics of delay claims in relation to effects and causes and assigning responsibility are a challenge for attorneys, jurists, and judges. Four-dimensional (4D) simulation can be considered ...
Near Real-Time Motion Planning and Simulation of Cranes in Construction: Framework and System Architecture
Publisher: American Society of Civil Engineers
Abstract: Motion planning of cranes is an important issue in construction projects, where rapid and accurate planning directly affects the safety and productivity of operations. The work presented in this paper is directed toward ...
Simulation-Based Optimization of Surveillance Camera Types, Number, and Placement in Buildings Using BIM
Publisher: American Society of Civil Engineers
Abstract: Many organizations claimed that the installation and maintenance of surveillance cameras in buildings is costly. In addition, once the surveillance cameras are placed, it is too costly to change their positions. The optimal ...
Bridge Planning Using GIS and Expert System Approach
Publisher: American Society of Civil Engineers
Abstract: In the planning process of a new road network, the planner should consider possible locations of bridges and tunnels. The selection of the best alignment imposes the need to investigate the effect of the location of each ...
