Completed in 2007, this project, awarded by the Port Authority of Barcelona, included the construction of several key elements for the expansion and improvement of the port infrastructure.

Among the main works is the execution of a 2,001-metre-long sloped breakwater, consisting of a quarry-run core protected by rock armour layers and blocks ranging from 15 to 60 tonnes, depending on the different sections of the structure.

In addition, a 1,699-metre-long vertical breakwater was constructed, running parallel to the coastline and built using 47 reinforced concrete caissons, providing a robust and efficient solution for port protection.

The project also includes a 300-metre-long caisson yard protection breakwater, formed by 30-tonne blocks placed over rockfill, as well as a temporary caisson storage area with a length of 950 metres.

Furthermore, a 1,920-metre-long port enclosure was developed, parallel to the coastline and with depths of up to -5 metres, structured by four perpendicular groynes. This enclosure is characterized by a sloped configuration with a quarry-run core and protective rock armour layers, ensuring stability and functionality.

SECTION III

The works also included the extension of the port breakwater in the Port of Barcelona, over a 1,150-metre-long section, enhancing the protection capacity of the harbor.

Particular attention should be given to the sloped typology of the structure, constructed using a quarry-sourced core, protected by multiple layers of rock armour and blocks of varying weights—reaching up to 40 tonnes—, adapted to the different sections of the extended breakwater.

Additionally, in Area 4, new breakwaters with a total length of 700 metres were constructed, also using a sloped cross-section composed of a quarry-run core and rock armour layers, ensuring both structural stability and effective wave energy dissipation.
