Pro-active Construction Management System

Research Abstract

Proactive Construction Management System (PCMS) integrates a real-time location technology with virtual construction technologies to facilitate workers to detect unnoticeable hazards (e.g. a heavy machine approaching from behind) and provide proactive hazard-specific voice warnings immediately to workers when they are exposed to dangerous situations. The location technology implemented in PCMS has better suitability in changing construction environments in terms of location accuracy, ease of deployment and maintenance, and costs of purchase.


Moreover, the real-time position data of labour and equipment collected by PCMS enables us to automate safety risk assessment with changing site conditions. Specifically, a quantitative model for hazard exposure assessment was developed. For ease of understanding, in the quantitative model, a hazard is analogised as a radiation source and the hazard exposure is then referred to as the radiation quantity received. The longer duration and closer proximity in which a person is exposed to a radiation (hazard), the more radiation the person receives (the higher risk to which the person is exposed). Consequently, PCMS can provide safety officers with an ongoing and immediate means of comparing safety risk trends from worker, hazard and project perspectives.

Judge's comments

“The system demonstrates an innovative application of location technologies to help workers detect and control hazards on construction sites. This proactive and real-time warning system has much merit in providing potential solutions for managing health and safety on site. The panel looks forward to its further testing and exploration in real-world contexts, especially with reference to workers’ behavioural responses.”
