PAC-4 is a project that entailed digging part of the new Panama Canal access channel to the Pacific in order to let Post Panamax ships pass through.  This project joined the new locks being built on the Pacific side with the so-called Culebra Cut located close to the Centennial Bridge, the narrowest strip of the waterway found only several kilometres away from the entrance to the canal.

In this context, FCC identified the following challenges:

• To preserve the plants and wildlife of the surrounding environment
• To responsibly operate on the land, anticipating the emergence of ruins with tremendous cultural and historical value iand possible deposits created through ground movement

• The Panama Canal expansion project was carried out in a wooded area, requiring the implementation of rigorous environmental measures such as animal relocation and reforestation works.
• A wildlife rescue plan was put in place whereby every time activity was carried out in a forest or wooded area, the first plan of action was to rescue the animals so that they could be relocated to national parks.
• A responsible tree-felling program was implemented so that for every tree that was cut down, the Panama Canal Authority, as the project developer, was obliged to plant another 10 in other part of the country.
• Given that the project was implemented in areas where construction works for the Panama Canal were carried out more than 100 years ago, items of high historical value were discovered during the excavation stage of the process. When this happened, the National Institute of Culture (INAC) were informed so that they could properly document the finds.

FCC successfully completed a key intervention for the construction of the new canal , preserving the environmental and historical richness of the environment through responsible and sustainable management of the resources.
