Afro-Panamanian
In 1904 when the construction of the Panama Canal was taken over by the United States for the failure of the French company, will again resort to the West Indian worker. Although between 1904 and 1914 the vast majority of Afro-West Indians who arrived in Panama did a one-year contract with the idea of returning to their home islands once the offshore project, after construction of the canal many Afro-Antillean stayed in Panama. Afro-West Indians who remained in Panama many got jobs in the Canal Zone and became the largest immigrant group in Panama. On the subject of Afro-Antillean Panama, Leslie B. Rout said that when the canal was opened in 1914, some 20,000 African-West Indians remained in Panama.
Panama Canal
It was announced in July 2009 that the Belgian dredging company Jan De Nul, together with a consortium of contractors consisting of the Spanish Sacyr Vallehermoso, the Italian Impregilo, and the Panamanian company Grupo Cusa, had been awarded the contract to build the six new locks for US$3.1 billion, which was one billion less than the next highest competing bid due to having a concrete budget 71 percent smaller than that of the next bidder and allotted roughly 25 percent less for steel to reinforce that concrete. The contract resulted in $100 million in dredging works over the next few years for the Belgian company and a great deal of work for its construction division. The design of the locks is a carbon copy of the Berendrecht Lock, which is 68 m wide and 500 m long, making it the largest lock in the world. Completed in 1989 by the Port of Antwerp, which De Nul helped build, the company still has engineers and specialists who were part of that project.
