Monitoring of Concrete Placement and Vibration for Real-Time Quality Control

This paper presents a conceptual framework for monitoring concrete placement and vibration operations. The proposed design is intended to enable collection and analysis of concrete pour data using computer vision and ultrasonic positioning. The system being developed alerts a project manager when workmanship observed is not in compliance with acceptable performance standards. The paper describes key operational factors in concrete placement and vibration that need to be monitored and reviews options for realtime locating systems. Fourteen factors related to concrete placement and their corresponding parameters are determined for measurement. In regard to the real-time locating systems, Ultra-wideband, ultrasonic, and computer vision technologies satisfy the expected levels of on-site positioning range and accuracy. Along with computer vision, ultrasonic technology has been chosen over Ultra-wideband alternative due to its lower cost and comparable performance. © 2019 The Authors.
