This statement is true. The FIDIC suite of contracts, including Red, Yellow, and Silver Books, have evolved from earlier editions and contract models, but they retain a common structure, terminology, and approach to risk allocation. This familiarity allows professionals who know one FIDIC contract to adapt more easily to other FIDIC contracts or updated editions. For example, common terms like Engineer, Employer, Contractor, Variation, and Claims exist across editions with consistent meaning.

The modular and familiar structure supports easier contract administration, negotiation, and interpretation. However, differences in clauses, obligations, and procedures between editions (e.g., 1999 vs. 2017) require careful review. Nevertheless, the shared foundations mean prior experience provides valuable understanding, streamlining learning and application.
