The FIDIC Red Book Contract: An International Clause-by-Clause Commentary

A book with the aforementioned characteristics, written by a leading author such as Christopher Seppälä, is essential for anyone working in the construction sector in Latin America, whether as a professor, researcher, or practitioner. — By Sergio GARCÍA LONG, Pontifical Catholic University of Peru/ UNIDROIT Correspondent - Revista de la Facultad de Derecho de México, Vol. 75, No. 293, 2025, 361-368

*Translated from French to English

This book is a very detailed commentary on the Standard Contract for Construction for International Projects: the "Red Book" in its second edition (2017, the "RB/17"), as rewritten with modifications in 2022. The "Red Book" covers the essentials of all the practical and legal problems that construction projects raise, while admitting sectoral and specific adaptations to certain contractual arrangements or to particular requirements. For his long experience within FIDIC, in contract law and international construction projects and their litigation, especially arbitration, the author is particularly recognized.

Clearly, for the vast world of construction worldwide, this well-researched, carefully and clearly written book is the benchmark for Red Book FIDIC contracts and, more generally, for international construction contracts.— Guido Carducci – JDI Journal du droit international "CLUNET" issue 2 -2025

This book is an excellent resource for anyone working with the FIDIC Red Book contract, as the book provides authorities from both civil and common law jurisdictions for a universal application. The thorough and well-researched analysis, coupled with practical insights and examples, makes it an invaluable tool for understanding the intricacies of this FIDIC form. — Thayananthan Baskaran and Shaagita Rajenthiran - This article was first published in Construction Law International, Vol 18 No 4, January 2024, and is reproduced by kind permission of the International Bar Association, London, UK. © International Bar Association

The Book is a one stop source, encompassing not only the FIDIC Red Book but the construction law jurisprudence surrounding it, including the corresponding provisions of the FIDIC Yellow Book and Silver Book. To describe the Book as a 'commentary' on the Red Book does not do justice to its breadth and insights. Seppala’s keen insights and unique vantage point makes the treatise an authority on the subject. — Sumeet Kachwaha Partner Kachwaha & Partners - ICAArbitration Quarterly Vol 218 I July-September, 2023

Christopher R. Seppala has written this Book with his common law background but with a perfect knowledge of the civil law system as a result of his mastering the French legal framework as member of the Paris Bar, but also from his experience working in numerous civil law countries around the world. He has also bene¿ted from his unmatched experience as business lawyer, counsel for numerous international construction contract negotiations and litigations and as ICC arbitrator. Where necessary he completed his personal knowledge with the assistance of a team of local and international experts and of a large civil law library

The book is much more than a commentary on the new edition of the Red Book and is well worth reading by all practitioners of international construction, even if they are not so much concerned by the very British form of the Red Book. As the former President of FIDIC rightly sums up in his foreword, this book ‘‘provides expert insight from a common and civil law lawyer with long experience in international construction contract disputes, as it discusses the approach of both systems of law to the many contractual issues which can arise in different parts of the world’’. This applies to all FIDIC standard forms and to other construction contract forms around the world.

It is really a book any lawyer, arbitrator, and other practitioners or students involved in the international construction should read and keep close to them as a reference book. – Bruno DE CAZALET – De Droit Des Affaires Internationales / International Business Law issue 1/2024

It seems safe to say that The FIDIC Red Book Contract: An International Clause-by-Clause Commentary is the definitive resource for users of the Red Book. It is exhaustive in its treatment of not only the Red Book itself, but also the surrounding context necessary to fully appreciate the Red Book. Ultimately, for those lawyers engaged on projects using the Red Book, or for those who wish to deepen their understanding, or develop an internationally informed understanding of the policy and negotiating considerations in regard to key issues in respect of construction contracts, this text is therefore essential reading.

It is not an exaggeration to say that, among international construction lawyers, Seppala’s expertise in regards to the FIDIC forms is veritably legendary: nor would it be an exaggeration to say that, even for Seppala, The FIDIC Red Book Contract: An International Clause-by-Clause Commentary represents a capstone achievement, the value of which will be realized by the global construction bar for many years to come. – Bruce Reynolds Legal Update #166- The Canadian College of Construction Lawyers

This landmark publication not only reaffirms Seppälä's authority in his field but also showcases his skill in clarifying the complexities of international construction law. Destined to become a seminal source, Seppälä's work will undoubtedly enrich the discipline and influence the practice and study of construction law globally for years to come. — Júlio César Bueno- Pinheiro Neto Advogados

Mr. Seppala not only provides a detailed analysis of each clause of the FIDIC Red Book as updated in 2022, but offers commentary on a host of other subjects important to gaining a more complete understanding of the FIDIC Red Book. No law firm that advises clients on international construction contracts subject to the FIDIC Red Book should be without Mr. Seppala’s fine contribution to our understanding of one of the most important sets of contract documents in the field of international construction law. — Philip L. Bruner / The Construction Lawyer” published by the American Bar Association Vol. 43- March 2024

Nonetheless, Mr. Seppälä’s work remains essential reading for all professionals who deal not only with FIDIC Red Book or FIDIC Red Book-based draft contracts, but also with all other FIDIC-based contracts, since many other FIDIC books (i.e., silver, yellow, gold, blue, green, etc.) contain similar provisions and have a common background and rationale. This book will therefore be a highly valuable resource for the drafting, negotiating and litigating of FIDIC-based contracts. – Ali Bennani - Les de Cahiers de l'arbitrage – 3, 2023

This is a magnificent book. It is a valuable resource for those in year one or year 50 of working with international construction contracts. I would strongly recommend it to anyone who has anything to do with FIDIC contracts. – Rupert Choat KC, ATKIN CHAMBERS - The International Construction Law Review, Part 4 -2023

Undoubtedly the book is an essential resource for all users involved in international construction projects, both new and experienced. Christopher Seppälä’s work is far more than a clause-by-clause review but provides new users a strong introduction to, and the author’s perspective on, the discussion of applicable law in relation to FIDIC contracts. It further provides the author’s detailed insight and analysis of many topics that a broad base of experienced users will find extremely valuable, including users of the FIDIC Yellow and Silver Books, which share many provisions with the Red Book, and users of the earlier versions of the Red Book who will find detailed comments on recent changes. – Daniel Schimmel / Jose M. Garcia Rebolledo - Foley Hoag. ICC Dispute Resolution Bulletin issue 3-2023

L’ouvrage de M. Seppala est une œuvre monumentale. M. Seppala a cherché à transmettre son savoir encyclopédique et son immense expérience des Contrats FIDIC. La contribution de cet ouvrage à diffusion de la connaissance du Livre Rouge est considérable. Les praticiens des contrats internationaux de construction lui en seront certainement reconnaissants. – Yann Schneller – Revue de l’Arbitrage 3- 2023

Christopher Seppälä is one of the world’s preeminent practitioners and leading authorities on international construction law and arbitration. He has been closely involved with the FIDIC Contracts Committee, either as a member or as an adviser, for over three decades. That involvement, together with his years of experience as advocate and arbitrator in construction disputes, makes Seppälä a genuine expert in the field. It is therefore no surprise that his latest book, The FIDIC Red Book Contract: An International Clause-by-Clause Commentary, is a remarkable contribution to the field of international construction law.

Presented over five chapters, this book is a comprehensive treatise on the FIDIC Red Book Contract. To provide the necessary context to the material that follows, the book first traces the evolution of international construction law in general and identifies the distinctive features of FIDIC Contracts. Seppälä then provides an insightful comparison of various versions of the FIDIC Red Book Contract, to develop the reasons behind the measured evolution of the FIDIC Red Book Contract.

Having dealt with this introductory material, the book then engages with a crucial and unique aspect of international construction law jurisprudence and practice: the confluence of the civil and common law systems. Seppälä explores the topics on which the two systems of law generally differ, explains how those differences can become relevant in the context of a construction project, and identifies the various principles and doctrines from these two systems of law that are typically at issue in construction disputes. 

This high-level analysis of the differences between the two legal systems, segues into a concise – but powerful and highly informative – summary of the principles of contract interpretation as they apply to construction contracts. Seppälä combines his mastery of the theoretical foundations of construction law with a keen understanding of commercial considerations to provide clear-cut practical advice on the interpretation of FIDIC contracts. This is an invaluable resource for those who wish to understand the doctrinal underpinnings of international construction law as well as those who seek actionable guidance on how to interpret a FIDIC contract.

The centerpiece of the book – as the title suggests – is a clause-by-clause commentary on the FIDIC Red Book Contract. Each provision of the FIDIC Red Book Contract is presented, analyzed, explained, and put in context. The book canvasses the relevant jurisprudence and notable commentary that is important for a full understanding of each provision. Where relevant, the book offers a side-by-side analysis of provisions from different versions of the FIDIC Red Book Contract to explain the evolution of the contract and the construction industry in general. Building on the previous chapters, Seppälä frames his analysis of each clause in its doctrinal foundations, while also ensuring that the clause is interpreted in the relevant commercial context.  

Seppälä’s work does not limit itself to the FIDIC Red Book Contract; it also addresses important ancillary material. The book includes a practical commentary on documents that provide for, and govern, the establishment and functioning of dispute adjudication boards. Seppälä also includes an analysis of three other documents from the suite of FIDIC documents relating to the Red Book Contract: FIDIC’s advisory note on building information modelling, FIDIC’s forms of performance and advance payment guarantees, and as well as the forms of letters of acceptance, contract agreement and dispute adjudication/avoidance agreements. This comprehensive analysis of these ancillary documents is useful for anyone seeking thorough and up-to-date guidance on the topic.

As is to be expected with a comprehensive treatise of this nature, the book is lengthy, spanning over 1400 pages. However, Seppälä succeeds in ensuring that the book is fit-for-purpose, providing an invaluable resource for international construction practitioners, construction law academics and students. His focus on making the material actionable is evident in the way the commentary for each clause is structured: the text of the clause, a summary of changes in different versions, an identification of related provisions, and then an analysis that also includes a critique of the provision where necessary.  

Indeed, the book’s length does not detract from its utility; it adds to it. The book stands out for its depth, rigour, and sheer quality of analysis. Most impressive, however, is the manner in which Seppälä is able to translate a lifetime’s worth of construction law experience into an easily digestible clause-by-clause commentary. This book is likely to be the authoritative commentary on all aspects of the FIDIC Red Book Contract for years to come. — Gary Born & Aonkan Ghosh, Arbitration International – October 2023

This is an authoritative commentary by an author with no fewer than three decades of FIDIC experience. What is even more impressive, however, is Christopher Seppälä’s desire to share his knowledge, his views and the immense effort he must have put into writing his commentary. This book deserves to be on the shelf of every FIDIC user. — Cavinder Bull SC & Christopher Chong – Asian Dispute Review October 2023

As Sibelius (another prominent Finn) once said, "Music is for me like a beautiful mosaic which God has put together. He takes all the pieces in his hand, throws them into the world, and we have to recreate the picture from the pieces." For the author of a book on construction law the same is true. All the materials are there in the world -- the contract, the statutes and code provisions, the judgments and awards. The task of the author is to pull them altogether, and to produce a written mosaic that will prove itself in its harmonious utility. Mr Seppälä's admirably accomplishes this task. Everyone who works with FIDIC contracts should have a copy of this excellent book.— Julian Bailey – BCL Journal 38 (2023)

Chris SEPPÄLÄ’s opus is incontournable for anyone involved in a FIDIC contract or dealing with international construction projects and contracts in general, including lawyers working in any role in construction arbitration, whether as counsel, arbitrator, adjudicator or legal expert. No other book currently on the market contains such a wealth of useful information on international construction contracting, while being easily accessible and practical. The book bridges the gap between theory and practice, enabling effective navigation through the contractual framework. In addition, by providing guidance on the drafting, negotiation, execution, interpretation and administration of a FIDIC contract, the book has what it takes to contribute significantly to a more uniform application of FIDIC contracts. — Bernd Ehle, ASA Bulletin issue 2-2023

Having read and considered the contents and structure of this unique and discerning book, I can only but draw one conclusion, and that is that this book is an essential reference material for anyone who is involved in international construction projects, whether a novice or experienced; whether an employer, contractor or engineer; whether a member of a DAB or a DAAB; or an arbitrator. — Prof. Dr Nael G. Bunni, Bunni & Associates Limited - Journal of International Arbitration 2023 issue 4

Seppälä’s commentary on FIDIC and related case law remains an oft cited authority in construction disputes, The FIDIC Red Book Contract: An International Clause-by-Clause Commentary is thus a book not to miss. Those practicing in the field of construction arbitration will find Seppälä’s new publication of tremendous value, whether based in Hong Kong, Singapore, elsewhere in Asia, or globally.— Olga Boltenko - Hong Kong Lawyer June 2023

There is nobody better able to produce a detailed analysis of the 2017 Red Book than he is.— The Hon. Sir Vivian Ramsey

Christopher R. Seppälä’s ‘FIDIC Red Book: An International Clause-by-Clause Commentary’ is an outstanding companion to all who aspire to have a truly international and comparative understanding of the FIDIC Red Book. This truly invaluable and must-have guide is a product of many years of expertise and wisdom amassed by a leading light in construction contracts and disputes. Comparing civil and common law approaches to various practical issues that arise under international construction contracts and in related disputes, analysing intricate and challenging applicable law issues, and providing an insightful Clause-by-Clause Commentary on the General Conditions of the Red Book 2017 are among the greatest contributions this book brings to scholars, practitioners and anyone with a vested interest in the field of construction law and practice.” — Prof. Dr. Mohamed Abdel Wahab, Zulficar & Partners Law Firm

This is quite literally a combination of “everything one needs to know” about international construction contracting. User-friendly guide for the experienced, and for those who are embarking on their first international. This commentary will be the definitive work on the FIDIC flagship Red Book for years to come. — John W. Hinchey
