Coursing of Las Huertas and El Cercado ravines in San Andrés.

Define and value the necessary Works for carrying out the coursing of Las Huertas and El Cercado Ravines, writing the construction Project for the Bridge that is to be built in order to join the village of San Andrés and Las Teresitas Beach, and Project for a maritime defence at the El Cercado Ravine mouth. These works can be summarized as follows:

• Transport withholding devices
• Coursing of the ravines, allowing drainage of the runoff measures for T=500 years, through walls and reinforced concrete girders.
• Driving rain waters from the neighbouring places to the channelling though pipes and coffers for de-sanding.
• Building the bridge at the crossroads between El Cercado Ravine and its own mouth.
