Construction company: SATO
Budget 9,530,323.96 €
At the end of 2018, the construction contract for the secondary breakwater of Naos was tendered. The design included a 320 meters breakwater with two different sections: a vertical section of 115 meters long to be executed with 4 concrete caisons, and another section for the first 205 meters of a rouble mound breakwater protected with a double armour layer of 10 tons cubic blocks.
The tendering process allowed the possibility of presenting an alternative design. SATO proposed a solution using a 6 tons single layer of CUBIPOD for the main section and a 12 tons single layer of CUBIPOD for the round head area connected to the concrete caisons.
The contract was finally awarded to SATO with its alternative solution. The proposal reached a 15% budget saving from the original budget of the Project and was successfully completed.
