Construction Claims Under FIDIC Contracts

FIDIC contracts govern major construction projects across the MENA region. We examine the claims framework, key procedural requirements, and common pitfalls.

The FIDIC Claims Framework: 1999 and 2017 Editions

FIDIC contracts — published by the International Federation of Consulting Engineers — are among the most widely used standard form contracts for major construction and engineering projects in the MENA region. The FIDIC suite, particularly the Red Book (construction), Yellow Book (plant and design-build) and Silver Book (EPC/turnkey), provides a detailed framework for the allocation of risk, the management of variations, and the resolution of disputes.

The 1999 FIDIC editions remain in widespread use across the region, and their claims framework is contained in Clause 20, which covers both claims and disputes (including arbitration). The 2017 editions substantially revised this structure: Clause 20 now deals exclusively with claims, while Clause 21 addresses disputes and arbitration as a separate regime. Practitioners must be precise about which edition governs a particular contract, as the procedural obligations and consequences differ materially between the two.

The 28-Day Notice Requirement

The most critical procedural requirement under both the 1999 and 2017 FIDIC editions is the obligation to give notice of a claim within 28 days of the date on which the claiming party became aware — or should have become aware — of the event or circumstance giving rise to the claim. Under the 2017 editions, this time-bar is codified in Clause 20.2.4: failure to give notice within the prescribed period results in the claiming party losing its entitlement to additional payment or an extension of time, subject to any applicable mandatory law of the governing jurisdiction that may limit the effect of contractual time-bars.

The 28-day notice requirement is strictly applied in many jurisdictions, and courts and arbitral tribunals in the UAE and wider MENA region have generally upheld time-bar provisions in FIDIC contracts. Contractors in particular must maintain robust contract administration procedures to ensure that potential claims are identified and notified promptly — the pressure of project delivery should not be allowed to crowd out the administrative discipline required to preserve claim rights.

Fully Detailed Claims

Following the initial notice, the claiming party is required to submit a fully detailed claim within 84 days (or such other period as may be agreed). The fully detailed claim must set out the contractual or other legal basis for the claim, the circumstances giving rise to it, and the relief sought — including the amount of additional payment claimed and/or the extension of time requested, supported by detailed particulars.

Where the event or circumstance giving rise to the claim has a continuing effect, the claiming party must submit interim claims at monthly intervals and a final claim within 28 days of the end of the continuing effect. The requirement to maintain contemporaneous records — daily records, correspondence, instructions, and cost data — is essential to supporting a fully detailed claim and should be built into project management procedures from the outset.

The Engineer's Role and the DAAB

Under FIDIC contracts, the Engineer plays a central role in the claims process. The Engineer is required to respond to a fully detailed claim within 42 days, either approving it, disapproving it with reasons, or requesting further particulars. The Engineer's determination is binding on both parties unless and until revised by a Dispute Avoidance/Adjudication Board (DAAB) under the 2017 editions, or a Dispute Adjudication Board (DAB) under the 1999 editions, or by arbitration.

The 2017 FIDIC editions introduced the DAAB as a standing dispute resolution body, replacing the DAB of the 1999 editions. The DAAB is intended to be appointed at the outset of the project and to remain in place throughout, providing a mechanism for the early and informal resolution of disputes before they escalate to formal adjudication or arbitration. In practice, the DAAB mechanism is not always implemented as intended — parties sometimes fail to appoint a DAAB, or appoint one only when a dispute has already arisen.

Common Pitfalls in FIDIC Claims

The most common reason for the failure of otherwise valid FIDIC claims is procedural non-compliance — in particular, failure to give timely notice. Other common pitfalls include inadequate contemporaneous records (making it difficult to substantiate the quantum of a claim), failure to distinguish between different heads of claim (delay, disruption, variations and prolongation costs each require separate analysis and substantiation), and failure to follow the contractual escalation procedure before commencing arbitration.

Employers are not immune from procedural pitfalls. The 2017 FIDIC editions impose the same notice and procedural requirements on employer claims — including claims for liquidated damages — as on contractor claims. Employers who fail to follow the prescribed procedure may find that their claims are time-barred or that their entitlement to liquidated damages is compromised.

Dispute Resolution: Arbitration and the Courts

FIDIC contracts typically provide for international arbitration as the final dispute resolution mechanism. The choice of arbitral institution — whether ICC, DIAC, ADCCAC, or another body — depends on the contract and the parties' preferences; no single institution is universally specified across MENA construction projects. The seat of arbitration and the governing law of the contract have significant implications for the conduct of the arbitration and the enforceability of any award.

In the UAE, construction disputes are also subject to the jurisdiction of the onshore courts and — for projects in the DIFC or ADGM — the courts of those free zones. The interaction between the contractual arbitration clause, the applicable procedural law, and the jurisdiction of the local courts requires careful analysis, particularly where interim relief is sought or where enforcement of an award is anticipated.

Key Points
  • In the 2017 FIDIC editions, Clause 20 governs claims only; Clause 21 governs disputes and arbitration — a material change from the 1999 editions where both were in Clause 20.
  • The 28-day notice time-bar is codified in Clause 20.2.4 of the 2017 editions — failure to notify on time can extinguish an otherwise valid claim, subject to applicable mandatory law.
  • Contemporaneous records — daily records, correspondence, cost data — are essential to substantiating a fully detailed claim.
  • The DAAB (2017) replaces the DAB (1999) and is intended to be appointed at project outset, not only when a dispute arises.
  • The 2017 editions impose the same procedural requirements on employer claims as on contractor claims.
  • Seat of arbitration and governing law have significant implications for the conduct and enforceability of any award.
