4S Safety and Beyond:
One Platform. Total Protection.
Varadise delivers a comprehensive, integrated 4S (Smart Site Safety System) solution that meets 100% of Hong Kong's DEVB requirements — DEVB Technical Circular (Works) No. 3/2023 for public works contracts and the Buildings Department’s mobile plant and tower crane alert requirements, which have applied to every stage of private works over HK$30 million.
Our COSMOS 4S platform combines IoT sensors, AI monitoring, and real-time analytics to create a proactive safety ecosystem—not just compliance, but a competitive advantage.
It runs on your existing site CCTV, flags unsafe acts at 95%+ accuracy against the 90% minimum DEVB specifies, and has carried 100% of the projects we support through to a CIC 4S Label.
