The Alternative Tender Project is drafted in order to carry out a more optimum design of the closure of the wharf subject of the Project with the existing Manuel Leirós wharf.
The project comprises the extension of the Leirós Wharf No. 2 of a length of 30.37 metres with a water depth of 12 metres in BMVE, so as to support in a perpendicular direction toward the south the berthing wharf of 283 metres long, with a water depth in BMVE of 15 metres.
In this Alternative Project the submerged concrete caisson of the design of the base solution is replaced by a structure formed by a stepped wall of submerged concrete.
In this manner adaptations to the formwork of caissons are avoided, and a perfect connection with the two connecting wharfs is guaranteed, as it is concreted against two caissons.
