The contract includes the installation and implementation of a control system on both viaducts.
Both Deza and Anzo 2 have an automatic system, developed by Ofiteco, for conducting checks during the construction phase. In addition, Deza will have instrumentation for monitoring whilst it is in operation. The majority of the instrumentation is based on fibre-optic sensors.
There was automatic monitoring during the construction phase of both viaducts of the hydraulic launch system and inclination induced in the piers by the friction of the deck, so that any alarm supplied by the sensors automatically stopped the launch system. An automatic control system was devised which guaranteed safety during launching. The following parameters were defined for that purpose:
