Since February 2023, the HKSAR Development Bureau has mandated that construction sites with capital works project estimates exceeding HK$30 million must adopt a Smart Site Safety System (SSSS) to enhance real-time monitoring of high-risk activities. SSSS connects smart devices seamlessly through a stable data transmission network, providing project managers with an integrated, intelligent platform.The system consists of three core components: a centralized management platform, smart devices, and stable communication networks, enabling managers to monitor site safety at all times and improve safety assurance and operational efficiency.
