About the Center

Built-informatics and Smart Cities Center is grounded in the Department of Architecture and Civil Engineering at City University of Hong Kong and connects that academic base to a wider cross-disciplinary research network.

Its work brings together intelligent construction, built-environment sensing, BIM, digital twins, AI systems, and robotics so research can move from method development toward real operational settings.

The Center is positioned as an academic platform: it supports research collaboration, talent development, and translation without collapsing into either a purely administrative unit or a commercial product story.

Research Themes

AI Agents for Construction Safety and Site Intelligence

From field capture to decision execution, this track focuses on Safety GPT, risk recognition, video-based site inspection, and automated reporting.

  • Safety GPT 1.0
  • Risk Recognition
  • Video Analytics

Multimodal Data Fusion for Scan-to-BIM and Progress Intelligence

This track integrates scans, point clouds, imagery, and BIM/CAD models for progress tracking, scan-vs-BIM comparison, automated analysis, and reporting.

  • Scan vs BIM
  • Point Clouds
  • Progress Tracking

Urban Gas Infrastructure Mapping and Operations

This track develops handheld scanning, SLAM, point-cloud segmentation, and pipe image segmentation for urban gas infrastructure mapping and maintenance.

  • Handheld Scanning
  • SLAM
  • Segmentation

Robotic Systems for Urban Construction and Maintenance

This track develops self-built hardware, multi-terminal integration, and autonomous indoor/outdoor navigation for robotic construction and maintenance systems.

  • Robotics
  • Autonomous Navigation
  • Integrated Devices
