LeanTech: How to Reduce the Ever-Increasing Equipment in Modern Road Tunnels ?
In recent years, the ever-increasing construction standard of road tunnels has led to a rapidly increasing workload for operation and maintenance organizations. This development is exacerbated by the ever-shorter life cycles of systems. In addition, unnecessary redundancies are implemented in the name of «safety». This article shows how to simplify technical installations without creating new risks and whilst always respecting safety. It highlights how systems and subsystems can be reduced or simplified and where unnecessary redundancies can be avoided. The article refers to a few typical tunnel systems such as those used for monitoring and control, lighting, ventilation, traffic control, detection and communication, power supply, or cabling purposes.
