Understanding FIDIC

by Kelvin Hughes

Published 20 December 2020

Understanding FIDIC explains in simple and practical terms what is often seen as a very complex range of international engineering and construction contracts.

Covering the FIDIC 2017 Red, Yellow and Silver Books (referred to as "The Rainbow Suite"), the book gives an overview of all three contracts, including coverage of changes between the 1999 contracts and the present 2017 suite. FIDIC contracts are widely used as far afield as Europe, the Middle East, Asia and Australia, and this book provides a practical yet thorough guide to the key elements that practitioners preparing and administering these contracts would need to be aware of.

In his approachable and readable style, Kelvin Hughes covers:

  • The obligations and responsibilities of the Employer, the Employer’s Representative, the Engineer and the Contractor
  • Quality and Defects Liability
  • Design Responsibility and Liability
  • Variations, Measurement and Payment Procedures
  • Progress, Delays, Extensions of Time and Completion
  • Suspension and Termination
  • Insurances
  • Employer’s and Contractor’s Claims
  • The Dispute Avoidance/Adjudication Board and the Resolution of Disputes
  • Tendering

Anyone working with FIDIC contracts whether as the Employer, Employer’s Representative, Engineer or Contractor will benefit greatly from this easy-to-read guide to the Rainbow Suite. Students on professional courses or researching the contracts for project work will also find this book extremely useful.


With the release of the new NEC (formerly the New Engineering Contract), the use of the family of contracts continues to grow worldwide, as does the importance of understanding its clauses and nuances to everyone working in the built environment. Now in its fourth edition, this set of contracts is different to others in concept as well as format, so users may well find themselves needing a helping hand along the way.

Written in plain English, Understanding NEC4: Term Service Contract offers a practical guide to the use and management of the NEC4 Term Service Contract (TSC). The authors describe the full life of a contract, from the initial selection of options and contract formation through to the operations period and ultimately termination and dispute resolution. Although born of the same stable as the NEC4 construction contracts, the TSC is aimed at maintaining infrastructure and differs significantly from its siblings.

This is the first book to be written on the new contract and takes the reader through the important provisions including communications, planning, early warnings, compensation events and payments. It is ideal for clients, contractors and their advisors describing how to deploy the contract successfully.
