FIDIC is the International Federation of Consulting Engineers (or Fédération Internationale des Ingénieurs Conseils in French). FIDIC has produced many publications, including the model form contracts, best practice guidances, research on sustainability, integrity and risk management. FIDIC model form contracts have been developed by this organisation since 1999, now they consist of several different books which are marked by colours. Thus, FIDIC model contracts also have the nickname "Rainbow suite of contracts". Basically, the "Rainbow Suite" include the following books:

* Yellow book: Plant and Design-Build Contract (2 editions: 1999 and 2017)

* Silver book: EPC/Turnkey Contract (2 editions: 1999 and 2017)

* Red book: Construction Contracts (2 editions: 1999 and 2017)

* Emerald book: Conditions of Contract for Underground Works (1st Ed 2019)

* Blue-Green book: Dredgers Contract (2 editions: 2006 and 2016)

* Gold book: Design, Build and Operate Contract Guide

* Pink book: Construction Contract Multilateral Development Bank Harmonised Ed (2 editions: 2005 and 2010)

This type of model contract is commonly used around the world because its author, International Federation of Consulting Engineers, collaborates closely with development banks such as World Bank, Africa Development Bank, Asia Development Bank, etc. Every construction project that is financed by these institutions must adopt the FIDIC contracts.

The Joint Contracts Tribunal, also known as the JCT, produces standard forms of contract for construction, guidance notes and other standard documentation for use in the constructionindustry in the United Kingdom. From its establishment in 1931, JCT has expanded the number of contributing organisations.

ITC (International Trade Centre) produces contracts specifically designed for small companies doing international business, covering the sale of goods, distribution, services and joint ventures. Many small companies are now engaged in international trade, but don’t have access to the necessary contract forms to protect themselves. ITC and leading legal experts developed eight generic contract templates that incorporate internationally recognized standards and laws for most small business situations.

CIPS has several model forms of contract designed specifically for IT buying and servicing.
