FIDIC is a French language acronym for Federation Internationale Des Ingenieurs-Conseils, which means the international federation of consulting engineers. It was started in 1913 by the trio of France, Belgium and Switzerland. The United Kingdom joined the Federation in 1949. FIDIC is headquartered in Switzerland and now boasts of membership from over 60 different countries. FIDIC published its first contract, titled The Form of contract for works of Civil Engineering construction, in 1957. As the title indicated, this first contract was aimed at the Civil Engineering sector and it soon became known for the colour of its cover, and thus, The Red Book. It has become the tradition that FIDIC contracts are known in popular parlance by the colour of their cover. This first contract by FIDIC was undertaken jointly with the International federation of Building and Public works. FIDIC's concerted effort at achieving broad consultation and acceptance of its contract forms has seen subsequent editions of its contracts being ratified by the International Federation of Asian and Western Pacific Contractors Association, Associated General Contractors of America and the Inter-American Federation of the Construction Industry, Multilateral Development Banks among others. Because of the broad support it enjoys, FIDIC contracts are the foremost contracts in international construction.
