FIDIC 2017 Claims: The Notices That Preserve—or Defeat—Contractual Entitlement

A contractor may have suffered a genuine employer-caused delay, incurred additional expenditure and maintained an extensive project record, yet face a substantial obstacle to recovery because the claim was not notified in the form and time required by the contract. Under the 2017 editions of the FIDIC forms, claims administration is not a matter to be reconstructed once a dispute reaches arbitration. It is part of the contractual machinery through which entitlement is established.

The first question in a disputed construction claim is therefore not simply who caused the event. It is whether the party claiming time or money used the procedure that the parties agreed would govern that event.

The distinction between an event and a claim

A variation, late instruction, failure to provide access, delayed design approval or changed physical condition may affect completion. That does not automatically establish an entitlement to an extension of time or additional payment. The contractual route to relief depends on the particular FIDIC form, the allocation of the underlying risk, the relevant Sub-Clauses and any amendments made in the Particular Conditions.

Under the unamended 2017 Red and Yellow Books, Sub-Clause 20.2 establishes a detailed procedure for claims by the Contractor and the Employer. Sub-Clause 20.2.1 ordinarily requires a Notice of Claim no later than 28 days after the claiming party became aware, or should have become aware, of the event or circumstance giving rise to the claim. Sub-Clause 20.2.4 deals with the fully detailed claim, ordinarily due within 84 days of that point, subject to the contractual qualifications and machinery for agreement or determination. The Silver Book must be checked against its own wording and the Particular Conditions; one should not transplant references from one FIDIC form into another without review.

Those periods are not merely diary entries. A late Notice of Claim may trigger a contractual objection to entitlement. The 2017 forms also contain safeguards and a procedure for considering a late notice, including an assessment of why notice was delayed and whether the recipient suffered prejudice. The correct analysis therefore goes beyond the simplistic statement that every late notice necessarily extinguishes the claim. The operative text, any timely response to the notice, and the parties' conduct must be examined.

The contract also distinguishes the initial notice from the particulars required to substantiate the claim. A letter advising that the project has been delayed is not necessarily a fully detailed claim. Nor does a detailed monthly progress report automatically satisfy a distinct contractual notice requirement.

The trigger date is often the real dispute

A claiming party may argue that time began to run when the extent of delay became measurable. The responding party may contend that the relevant facts were already known weeks earlier. The contractual trigger generally concerns awareness of the event or circumstance, not necessarily the date on which its financial consequences could be calculated precisely.

Consider delayed approval of construction drawings. The contractor may have communicated the issue repeatedly through progress meetings. The critical exercise is to identify when the delay became an event giving rise to a contractual claim, what notice was issued in response, and whether the recipient was able to investigate its consequences contemporaneously. The exercise is factual and contractual; it cannot be answered by applying a fixed date to every design issue.

The same problem appears in continuing circumstances. A sustained failure to provide access or prolonged interference may require updated or interim particulars and a final claim once the effects have ceased. The distinction between a single event and continuing effects should be established from the contract, programme and project record.

Why records must be prepared for an entitlement analysis

A claim for an extension of time is not proved simply by exhibiting a revised completion date. It should be connected to the delay event, the contractual risk allocation and the programme against which critical delay is measured. Contemporary programmes, instructions, correspondence, inspection requests, site diaries, progress certificates and records of available work fronts may all be decisive.

Equally, a cost claim requires proof of causation and amount. The fact that a contractor remained on site longer than expected does not establish that every prolongation expense is recoverable from the Employer. The claim must distinguish employer-risk events from contractor delay, overlapping causes, mitigation measures and any costs already compensated through other contractual mechanisms.

The contractual notice should therefore be drafted to identify the occurrence and preserve the relevant right. The fully detailed submission can then set out the contractual provision, factual chronology, causation analysis, programme consequences and financial calculation. Treating those documents as interchangeable creates avoidable risk.

The place of the Engineer, Employer's Representative and dispute boards

The 2017 FIDIC scheme places substantial importance on agreement or determination before the dispute proceeds through the agreed escalation mechanism. Under the Red and Yellow Books, Sub-Clause 3.7 addresses agreement or determination. The Silver Book has a different administrative structure, which must be read in its own terms.

A party should not assume that the mere submission of a claim automatically produces a binding determination, or that a delayed determination permits it to disregard the next contractual step. The precise procedure may involve formal notices of dissatisfaction, dispute avoidance or adjudication before arbitration. Errors at one stage may affect jurisdiction, admissibility or the scope of the subsequent dispute.

The Islamabad High Court's decision in *China International Water and Electric Corporation v National Highway Authority* (2023 CLD 1400) arose at the enforcement stage of a foreign arbitral award. It illustrates a separate but important point: governing law, arbitral seat and enforcement procedure are distinct legal questions. A contractor whose project records support its claim must still ensure that the dispute is pursued in the agreed forum and procedural sequence. The judgment should not be cited as authority that non-compliance with FIDIC notice provisions is excused.

What employers should do on receipt of a notice

The employer's interests are not served by ignoring claim notices until final account negotiations. Under the relevant FIDIC form, the recipient may have a defined period in which to object to late notice or request further particulars. Failure to engage with that machinery can complicate a later time-bar objection.

An effective response identifies the claim concerned, reserves the contractual position accurately and asks for the records needed to evaluate cause and effect. It should avoid treating every notification as an admission of liability, while also avoiding a blanket rejection unsupported by the contract or the project record.

Where performance security, liquidated damages, termination or withholding is contemplated, the employer should consider whether the same delay events are being treated consistently across the contractual documentation.

Drafting and claims administration are inseparable

The legal position in a FIDIC claim cannot be assessed from the standard form alone. Particular Conditions frequently alter notice periods, define communication methods, change administrative roles or modify the dispute-resolution sequence. The signed contract, appendices and amendments are therefore the first authorities to examine.

For an ongoing project, a live notice register is more valuable than a retrospective compilation of correspondence. It should record each potential event, awareness date, contractual provision, notification, acknowledgement, supporting record, due date for particulars and determination. The project programme and financial records should use the same event identifiers.

The central point is straightforward: the underlying facts may justify relief, but the entitlement must be preserved and proved through the contract. A persuasive arbitration case begins in the project administration file, not in the statement of claim.
