FIDIC Contract

FIDIC contracts are the most widely used standard forms for international construction and engineering procurement. Originating from the International Federation of Consulting Engineers (Federation Internationale des Ingenieurs-Conseils), the suite covers a broad range of project types and is the default choice for infrastructure projects financed by the World Bank, European Bank for Reconstruction and Development (EBRD), and other multilateral lenders operating across Europe and globally.

What is a FIDIC Contract?

The FIDIC suite, now in its 2017 second edition for the main forms, includes four core contracts known by their cover colours:

The Red Book (Conditions of Contract for Construction) is used where the employer provides the design and the contractor builds to that design. It uses a remeasurable bill of quantities (BOQ) as the pricing basis. This is the most commonly used form for civil engineering works such as roads, bridges, and water infrastructure.

The Yellow Book (Conditions of Contract for Plant and Design-Build) is used where the contractor carries both the design and construction responsibility. The contractor provides a lump sum price against employer's requirements, making it suitable for mechanical and electrical plant installations and design-and-build building projects.

The Silver Book (Conditions of Contract for EPC/Turnkey Projects) places maximum risk on the contractor, who assumes responsibility for design, procurement, construction, and commissioning for a fixed price. It is used for power stations and process plants where the employer wants price certainty and transfer of almost all construction risk.

The Gold Book (Conditions of Contract for Design, Build and Operate) covers the full project lifecycle including an operation period, making it structurally closer to a public works concession arrangement.

FIDIC contracts use an Engineer as the contract administrator, a role distinct from either party. The Engineer certifies payments, assesses claims, and determines disputes in the first instance. The 2017 editions introduced a new "determinations" process with formal timelines for the Engineer's decisions, and a standing Dispute Avoidance/Adjudication Board (DAAB) as the primary dispute resolution mechanism.

Practical completion in FIDIC terminology is "Taking-Over" by the employer. The defects liability period is the "Defects Notification Period," typically 365 days from taking-over.

Why it matters for bidders

FIDIC contracts allocate risk differently from NEC and JCT. The Red Book places design risk firmly with the employer, giving the contractor a straightforward build-only obligation with compensation for unforeseen ground conditions. The Yellow Book transfers design risk to the contractor. Bidders must match their risk appetite and insurance cover to the correct FIDIC form.

The 2017 editions also impose tighter notice obligations. Failure to give notice within the specified timeframe (typically 28 days of the event) may bar a contractor from recovering additional time or money, making contractual administration a competitive differentiator.

Example

The European Bank for Reconstruction and Development finances a motorway rehabilitation project in Ukraine. The contract uses FIDIC Red Book 2017 conditions, with a BOQ priced in EUR. The Engineer is an independent consulting firm appointed by the contracting authority. All disputes go first to the DAAB, then to ICC arbitration in Vienna if unresolved.

Frequently Asked Questions

Which FIDIC form is most commonly used in European public procurement?

The Red Book is most common for civil infrastructure. The Yellow Book is frequently used for design-and-build building projects and M+E installations. The Silver Book appears in energy and process plant projects. EBRD and World Bank-financed projects across Central and Eastern Europe and Ukraine predominantly use Red or Yellow Book.

Is FIDIC legally compatible with EU procurement rules?

Yes. FIDIC is a set of contract conditions, not a procurement procedure. It can be used as the contract form for any works contract procured under Directive 2014/24/EU. The choice of contract form is separate from the choice of procurement procedure.

What is the difference between the 1999 and 2017 FIDIC editions?

The 2017 editions include more prescriptive procedures for Engineer determinations, introduce a standing DAAB instead of an ad hoc dispute adjudication board, expand notice requirements, and rebalance certain risk provisions. Many projects still use 1999 editions; always confirm which edition applies before pricing.
