Failure of temporary support falsework systems results in serious accidents, often causing severe casualties and injuries. Previous research has demonstrated that an IoT-enabled falsework monitoring system can be effectively utilized in construction and demolition works to monitor both load and inclination data. This paper describes the stages undertaken from research and development, through system evaluation, to deployment, and the subsequent data captured from a large-scale application of the IoT-enabled falsework monitoring system in a critical infrastructure in Hong Kong. The aim is to ensure safe construction practices and provide early warnings for temporary structures used on-site. The works described in this paper is a continuation of previously published works referenced herein.
