Regarding the onshore part of the project, the footprint of the buildings covers about 7800 m2 of closed and covered spaces that are distributed on 2 levels.
Along the development of the Darsena di Ponente, 6 buildings will be built, with deep foundations made of sleeved micropiles with a diameter of 200 mm and a length of 9 m.
In the offshore part, the landing place is protected by two lines of floating breakwaters, respectively a 240.00 ml lateral line, made up of 12 breakwaters measuring 20.00 m x 8.00 m with an allowable load of 400 kg/m2, and an external line of 180.00 ml made up of 9 breakwaters measuring 20.00 m x 10.00 m with of 400 kg/m2.
Both lines are anchored to 900 mm diam. discrepiles, 12.5 m long,with SR 30 mortar with a compressive strength of 32 N/mm2, reinforced with Ø 298.5 mm pipe, 25 mm thick for the first 2 m and 12.5 mm thick for the remaining part with the insertion of a ø 44 mm chain for 6.50 m. The internal floating pontoons are anchored to 600 mm diam. discrepiles, 9.60 m long, poured with SR 30 mortar, with a compressive strength of 32 N/mm2, reinforced with Ø 193.7 mm pipe, with a thickness of 20 mm for the first 2 m and 10 mm thick for the remaining part.
