Before diving into the guide itself, it's important to understand the significance of the FIDIC 2017 updates. The International Federation of Consulting Engineers (FIDIC) publishes the world's most widely used standard forms of contract for international construction projects. In 2017, they released a major update to their "Rainbow Suite," which includes the Red Book (for works designed by the Employer), the Yellow Book (for plant and design-build projects), and the Silver Book (for EPC/Turnkey projects). These 2017 editions introduced a host of new procedures and requirements that significantly changed how parties manage projects and resolve disputes. Key changes included a more formal, multi-tiered dispute avoidance and adjudication process (DAAB), stricter time-bar clauses for claims, and more detailed provisions for notices.
