United for the Canal Group (GUPC), made up of Sacyr (41.6%), the Italian Impregilo, the Belgian Jan de Nul, and the Panamanian CUSA, was awarded in 2009 the design and construction contract for the third set of locks in the Panama Canal in the amount of 3,118 million dollars. Said work was delivered in June 2016. However, there were serious disagreements between the parties (GUPC and the Panama Canal Authority - ACP), in fact, the works were paralyzed in 2013 due to discrepancies regarding cost deviations. The bulk of the deviations are due to the quality of the basalt, unexpected failures in the land on which the work was carried out, strikes and regulatory changes. There are also disagreements over the guarantees granted by the GUPC to the Canal Authority.

Thus, in December 2016, the GUPC submitted 2 claims for cost overruns and delays to the International Court of Arbitration of the International Chamber of Commerce (ICC), for $ 5,673 million. ACP hires lawyers to defend itself against the aforementioned claims, which it considers to be unfounded.

As of 2015 (during the years 2009 to 2015), GUPC has recognized revenues from ordinary activities for USD 2,800 MM and costs of sales for USD 2,700 MM; In addition, it maintains an inventory for USD 2,000 million, where it capitalized different costs that it has not been able to invoice. There are no other balance sheet accounts or results related to the project at the end of 2015.
