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
• 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.
• Enhance site safety monitoring through digitalization
• Reduce blind spots and response times to incidents
• Automate compliance records and inspection workflows
Enhancing Safety with 360 AI Cameras in Mobile Plants
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.
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.
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.
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
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.
Smart Water Level Monitoring Solution
The Water Level Sensor is a reliable and efficient device designed for real-time monitoring of drainage and water levels. It delivers accurate readings and instant alerts, making it a vital tool for flood prevention and site water management.
• Real-time monitoring with accurate alerts
• Cloud integration for instant data upload
Height Access Control Solution
The Height Limit Device ensures safety in height-restricted areas by detecting over-height vehicles, triggering alerts, and preventing collisions with structures such as scaffolding and temporary bridges.
• Controls vehicle height to prevent collisions
• Detects over-limit heights and triggers alerts
• Integrates with CMP for centralized monitoring
Scaffold Tilt Monitoring Solution
The Angle Sensor monitors the tilt angle of scaffolding and temporary structures. Once the tilt exceeds a preset safety threshold, the system automatically triggers alerts to prevent collapse.
• Set alarm thresholds for safe tilt angles
• Triggers alerts when angles exceed limits, indicating potential structural failure
Advanced Hoisting Monitoring Solution
This solution enhances crane safety by integrating AI and wireless monitoring devices for continuous, real-time supervision of hoisting operations. It detects abnormal activity, provides instant alerts, and enables fast incident response.
• Real-time monitoring of crane operation
• Immediate response to any safety abnormalities
