In December 2021 FIDIC issued its 2nd edition of the Green Book. It is not so much an update to the 1st edition as a new and improved, intermediate form of contract. FIDIC is promoting it as a simpler, user-friendly alternative to the FIDIC 2017 Red and Yellow Books, where significant contract administration and management resources are not needed. The Green Book 2nd edition is recommended to be used by the World Bank for projects up to US$ 10 million. The Green Book 1st edition was originally intended for projects of US $500,000 with no more than a 6-month duration. However, the Green Book 1st was sometimes used for larger projects with a duration of up to two years. The Green Book 2nd therefore takes over from where the Green Book 1st left off. This is to be welcomed. The FIDIC 2017 suite of contracts (Red/Yellow/Silver) is unsuitable for smaller projects where less administration is required. The Green Book 2nd will therefore fill a much-needed gap in the FIDIC rainbow and is likely to be attractive to both Contractors and Employers. This article looks at some of the key features of the Green Book 2nd.
