Project Name
Smart Site Safety Empowering Public Housing Construction at Kai Tak 2B3 & 2B4'
Enhancing Safety and Visibility at Kai Tak Public Housing Sites with 4S System
Digital Safety in Action: Kai Tak Public Housing Project with Smart Site Integration
Project Background
• The construction of public housing developments at Kai Tak Sites 2B3 and 2B4 involves large-scale residential blocks, high-risk lifting activities, and complex site coordination.
• To improve visibility, compliance, and safety efficiency, the Smart Site Safety System (4S) was deployed throughout the site.
Objective
• Enhance site safety monitoring through digitalization
• Reduce blind spots and response times to incidents
• Automate compliance records and inspection workflows
Project Name
Enhancing Safety with 360 AI Cameras in Mobile Plants
Client Overview
This initiative involved six construction and engineering companies:
• Kanson
• Robinson
• Ahngau
• AHD
• Kamwing
• Shing Fung
Who implemented Ranger 360° systems across their mobile plant operations to improve site safety and surveillance.
Challenge
Mobile plants often operate in dynamic and high-risk environments. Limited visibility, blind spots, and frequent human-machine interactions increase the risk of accidents, near misses, and operational inefficiencies.
Objective
The goal was to enhance operator awareness, improve site visibility, and enable real-time monitoring through smart AI cameras — ultimately reducing risks and preventing incidents.
Solution
We deployed 360° AI-powered surveillance systems featuring:
• Panoramic real-time monitoring with full blind spot coverage
• AI intrusion detection to identify personnel within restricted zones
• Video capture & playback for safety audits and incident review
• Visual and audio alerts to warn operators in real time
Conclusion
The 360 AI Camera system has proven to be a vital solution in enhancing mobile plant safety. Keen Rich remains committed to working with industry partners to expand smart safety technologies into more complex and high-risk construction scenarios.
