FIDIC Contracts UK: Guide to International Projects

What this document is

FIDIC contracts are a family of standard form agreements used to set out the rights, obligations and risk positions of the parties on construction and engineering projects. The suite is often called the 'Rainbow Suite' because each book is identified by the colour of its cover.

The main forms include the Red Book for works designed by the employer, the Yellow Book for plant and design-build projects led by the contractor, the Silver Book for turnkey and EPC work where the contractor takes on more risk, and the Green Book for smaller and simpler works. Newer additions such as the Emerald Book cover tunnelling and underground works, and the Gold Book deals with design, build and operate arrangements.

Each form follows a similar structure, covering the role of the engineer, payment mechanisms, variations, time extensions, testing, defects liability, termination and dispute resolution. The contracts are drafted in a jurisdiction-neutral way, which means they must be read alongside the governing law chosen by the parties, often civil law in the host country or English law by agreement.

How to use this document

1. Identify the right book for the project. Start by matching the nature of the works to the appropriate FIDIC form. Employer-designed civil works usually call for the Red Book, contractor-designed plant or building work fits the Yellow Book, and turnkey projects with a fixed price and single point of responsibility generally use the Silver Book. Choosing the wrong form creates risk allocation problems that are difficult to fix later.
2. Draft the Particular Conditions carefully. FIDIC contracts are built from General Conditions that rarely change and Particular Conditions that tailor the deal to the specific project. The Particular Conditions are where governing law, language, currency, insurance requirements, performance security, liquidated damages and country-specific amendments are set out. This is the part of the contract that demands the most attention during negotiation.
3. Understand the role of the Engineer or Employer's Representative. Most FIDIC forms give a central administrative role to the Engineer, who issues instructions, certifies payment and makes determinations on claims. Under the Silver Book this role sits with the Employer's Representative instead. Both parties need to understand how this figure operates and the duty of fairness or impartiality that attaches to the role.
4. Follow the notice and claims procedures strictly. FIDIC contracts impose strict time bars on claims for additional payment or extensions of time, often requiring notice within 28 days of the triggering event. Miss the window and the claim can be lost entirely. Good record keeping, clear correspondence and early notification are not optional, they are contractual requirements.
5. Plan for disputes through the DAAB and arbitration. The current FIDIC forms use a standing Dispute Avoidance and Adjudication Board appointed at the start of the project. If a dispute cannot be resolved by the DAAB, it typically proceeds to international arbitration, often under ICC rules. Parties should agree the seat, rules and language of arbitration in the Particular Conditions rather than leaving it to chance.
