The document provides an overview of changes to FIDIC contracts, specifically the 2017 editions of the Yellow, Silver, and Red Books (the "Rainbow Suite"). Key changes include an increased emphasis on dispute avoidance through enhanced project management procedures and the establishment of standing Dispute Avoidance/Adjudication Boards. The role of the Engineer is revised to act neutrally rather than for the Employer. Additional changes aim to improve processes for extensions of time, variations, payments, and claims handling.
