Tracking and Managing Construction Sites Using Digital Twins: A Virtual Tour with AI-Segmented Changes
Construction sites change daily, but tracking and decisions are still made using on-site visits. This hands-on workshop combines scanning, AI-based change detection, and web-based 3D visualization with speculative scenario building. Participants prototype an automatic workflow in which construction-site management and teams receive daily-updated digital twins as a routine interface for coordination. Using consumer-grade hardware and open-source tools, participants build and compare successive site models, then reflect on how real-time digital twins reshape decision-making, roles, and collaboration between design and field teams. The outcome is both a working digital twin and a critical understanding of its impact on AEC practice.
