A monitoring system for real-time interference control on large construction sites

This paper surveys the feasibility of an infrastructureless real-time monitoring system to provide prompt support for inspectors in charge of health and safety management on construction sites. The system was tested in the specific application of monitoring interference between teams working on large construction sites. The system accounts for a wireless and untethered tracking technology and a local server running a software tool for handling collected data, real-time site state visualization and remote interaction with safety inspectors. The low-level tracking technology is a ZigBee-based easily deployable and reconfigurable technology. In this paper the system is found to be able to cover large fields while keeping its non-invasive features, thanks to the implementation of a novel low-power approach. This paper shows the degree of support inspectors can get from the system: it is able to alert in the occurrence of interference and to log any unexpected behavior.

► We have tested a non invasive monitoring system for construction sites.
► We have customized the system to detect unauthorized interferences.
► A user-friendly software interface to be used by H&S coordinators was developed.
► Testing was performed in our machine laboratory and on a real construction site.
