Project required the production and casting of 5.750 cub.m concrete (for the basin, concrete weight blocks, intake head, etc.), 23.000 cub.m of excavation (for both basin and trench excavation), 25.000 cub.m of backfilling (for both temporary protected reclamation, basin and trench), all offshore works required for the installation of pipes, intake heads, warning system, cathodic protection, etc.
Two rows of 644 m long 1400 mm diameter HDPE intake pipes were supplied by SIDEM.
Scope of Work
Execution of all necessary surveys, like seven borings (3 onshore + 4 offshore) as part of geotechnical surveys and topographical and bathymetric surveys to define site conditions.
Design studies to enable the final design of the system.
Detailed structural design, material supply and construction of reinforced concrete basin with two intake channels, including excavation as the structure is buried.
