Success Story - A Collaborative Excellence with Karta-X Technologies

Enhancing Construction Safety at Landfill Site with AI Cameras Enabled by Private 5G

Establishing a Safety-First Connected Construction Site

Low-latency Private 5G enables real-time hazard detection

Construction professionals in Hong Kong face unique safety challenges in dense urban environments, where a single incident can compromise worker well-being and jeopardise project progress. Construction sites demand solutions that work as hard as the construction workers do — not just monitoring but actively protecting the team and investment. While current monitoring systems may meet basic requirements, they're often reactive rather than preventive, leaving many projects vulnerable to costly delays and safety incidents. Emerging AI technologies also face bottleneck in optimising  operation without robust, high-bandwidth, secure and ultra-low latency wireless connectivity. 

A pilot project to explore the feasibility and effectiveness of AI-powered solutions with a dedicated network addressing these potential challenges in most construction sites was conducted in a landfill site. 

By deploying Karta-X's AI vision with NTT's high-performance Private 5G (P5G) at the site, the operator gains unprecedented control over site safety. This technology partnership enabled Karta-X to develop safety solutions specifically tailored to address the site's most pressing challenges and sustainability requirements.

BACKGROUND

Construction professionals in Hong Kong face unique safety challenges in dense urban environments where one incident can jeopardise entire projects. Construction sites demand solutions that work as hard as the construction workers do — not just monitoring but actively protecting the team and investment. While current monitoring systems may meet basic requirements, they're often reactive rather than preventive, leaving many projects vulnerable to costly delays and safety incidents. 

NTT's Private 5G (P5G) innovation ecosystem, featuring innovation hub CROSS LAB Hong Kong, provided the technological foundation for Karta-X to develop safety solutions specifically tailored to address construction sites’ most pressing challenges. 

"Safety has always been the primary concern in high-risk environments, specifically in construction sites. A site specific centralised management platform, sensors and specialised AI cameras empowered by Private 5G, can be leveraged to address safety issues and improve site management, ensuring a connected, safety-first environment that is both scalable and sustainable.

CHALLENGES

General challenges that the construction industry is facing daily

Equipment Incident

Equipment incidents account for 60% of reported incidents and are one of the four major construction incidents. 

Equipment Incident

Manpower Overload

Traditional devices require significant manpower for footage monitoring, problem identification, and necessary follow-up procedures.
Manpower Overload

Challenges of deploying AI or advanced technologies in an outdoor environment 

Delayed Hazard Response

Existing networks create critical gaps between danger and detection, putting workers at risk when every second counts.
Delayed Hazard Response

Limited Coverage

Complex sites with multiple levels, heavy machinery, and dense materials create connectivity dead zones with standard Wi-Fi and 4G and limiting AI application enablement. 

Limited Coverage

Cloud Uploading

Unstable network connections restrict upload functionality, making it difficult and inconvenient to retrieve data for analysis and record-keeping.

SOLUTION

AI Cameras + NTT's Private 5G: Vision Meets Velocity

The integrated Karta-X and NTT solution enhances the followings of the landfill site: 

  • Stability: The In-house AI powered by NTT's 26-28GHz mmWave Private 5G spectrum enables real-time Edge AI detection, giving operation teams instant awareness and alert when incident happens across the entire operation. 
  • Flexibility: Customizable AI detection services enable the site operators to opt for the right, affordable plan that works best for their objective. 
  • Visibility: Through data collected, risks and potential danger are predicted and identified for improvement in the future. 
  • Adaptability: the all-in-one structure of the P5G-enabled AI camera makes installation, deployment and dismantlement easy.

BENEFIT

95%+ AI Accuracy Achieved

Providing real-time, actionable insights for follow-up, improvement, and most importantly, protecting the sites and workers from potential dangers.

85% Improved Safety

Workers returned home safely every day with proactive PPE and machinery monitoring that minimized chances of life-threatening accidents.

Cost Savings

Project budgets stayed on track from reduced inspection personnel costs while accident-related downtime was eliminated.

INDUSTRY IMPACT

On top of the delivered benefits, we are bringing transformative impact to Hong Kong's construction sector that contributed US$133 billion to Hong Kong GDP in 2023. 


  • Regulatory Leadership: Projects will exceed Hong Kong's Construction Industry Council safety requirements, positioning users as an industry leader. 
  • Smart City Synergy: The adoption aligns with Hong Kong's 2025 Smart Construction Roadmap, creating opportunities for users for additional government infrastructure projects. 
  • Cross-Industry Model: Implementation creates a blueprint for safety excellence, as showcased in NTT Innovation Alliance ecosystem, that is now applicable across manufacturing and logistics operations.
