1. Key safety issuesA real time controlling and monitoring system is an important part of the safety management system.

The hazards inhered within the works area :The number of accesses is limited The works area is arranged in complex grids of buttress walls.

RFID Contactless Access Controllingand Recording System173. Continuous Improvements, Development and ExpansionAs out raft foundation is full of buttress wall, it would be difficult to monitor the status of worker within.

We are planning to setting up more RFID receivers to monitor the location of workers within, it will be easier to locate workers inside during emergency situation.
