Jakob Sørensen’ s companions to the 2017 editions of the FIDIC Red, Yellow and Silver Books are practical guides for anyone using the new FIDIC editions. They include informative chapters on construction projects and the FIDIC Conditions of Contract, followed by a clause-by-clause commentary on the Sub-Clauses in the new FIDIC editions, which forms the bulk of the companions, and several appendices. For a number of reasons, these companions are of great value. They are among the first books on the market dealing with the new 2017 FIDIC editions. The companions have a clear structure and are written in a straightforward language accessible to anyone. Having the background of a practising lawyer with substantial experience in construction law, Mr. Sørensen has succeeded in creating highly informative reads with a clear practical approach to the topics discussed. The clause-by-clause commentary in the companions contains clear and informative analysis of the discussed Sub-Clauses, which addresses a number of issues not covered in similar books on the market. The Appendices to the companions are also of great practical value, especially to those involved in the drafting of contracts based upon the FIDIC Conditions, as they contain sensible and useful suggestions for amendments or clarifications to the General Conditions, which contracting parties may consider introducing in their contracts. There is no doubt that these companions merit a strong recommendation. They are a must read to any construction professional dealing with or interested in the new FIDIC editions, including engineers, contracting parties and their legal advisors.
