Notice Requirements for EOT Claims — Time Bars and Condition Precedents

Notice requirements in construction contracts are not bureaucratic formality. They are, in many contracts, the gateway to legal entitlement. Where a notice requirement operates as a condition precedent, failure to give notice is not cured by demonstrating that the delay event was real, causally significant, and expensive. The entitlement is simply lost.

The Problem

Construction projects move fast, and the contractual notice obligations for delay events — which require written notice within a defined period (often 28 days) of the event becoming apparent — are frequently overlooked in the pressure of project delivery. The notice requirement seems like administrative detail when the project is running. By the time the contractor realises the significance of the notice obligation — typically at the point of submitting a consolidated claim — it may be months too late.

The consequences are severe. Under FIDIC Red Book 1999, Clause 20.1 is one of the most litigated provisions in international arbitration. It states that the contractor shall give notice of a claim within 28 days of the event (or its knowledge of it), and that if no notice is given, the time for completion shall not be extended, the contractor shall not be entitled to additional payment, and the employer shall be discharged from all liability in connection with the claim. This is express condition precedent language, and it has been enforced consistently.

The Legal Principle

Whether a notice requirement is a condition precedent depends on the precise wording of the clause. The distinction between the following is significant:

– *”The contractor shall give notice…”* — a procedural obligation only; late notice does not automatically bar the claim.

– *”The contractor shall not be entitled to… unless notice has been given…”* — a condition precedent; late notice bars the claim.

– *”…the contractor’s entitlement shall be limited to what it has notified…”* — conditional entitlement; only events notified are compensable.

English courts have applied condition precedent language strictly in commercial contracts between sophisticated parties. In Steria Ltd v Sigma Wireless Communications Ltd [2007] EWHC 3454, the TCC upheld a time bar, rejecting arguments based on waiver and estoppel.

Under NEC4, the early warning and compensation event notification obligations operate differently — a failure to notify a compensation event within the specified period (8 weeks under NEC4, Clause 61.3) results in the compensation event being assessed as if the prices and completion date were not affected, which is a different form of sanction but equally significant.

Practical Application

For contractors: implement a rigorous delay event tracking system from project start. Every event that could constitute a qualifying delay should be logged on the day it becomes apparent, and the 28-day (or contractually specified) clock should be tracked automatically. Do not defer notice pending assessment of the full impact — most contracts allow for notice of the event before the full claim is quantified.

For employers and contract administrators: do not routinely waive late notices without understanding the consequences. A pattern of accepting late notices may constitute waiver of the condition precedent. However, refusing late notices in circumstances where the employer was fully aware of the event and suffered no prejudice from late notification may invite a challenge to the time bar’s enforceability.

Risks

For contractors: the risk of losing a meritorious EOT and associated cost claim through failure to give notice is one of the most significant avoidable risks in construction claims management. A six-month delay event worth millions of pounds in prolongation costs can be lost entirely through a procedural failure.

Mitigation

Establish a notice obligation calendar at project start. Assign responsibility for notices to a designated person. Implement a delay event register that automatically flags upcoming notice deadlines. Train the project team on the distinction between the notice obligation and the full claim submission — notice comes first, the quantified claim follows.

Conclusion

Notice requirements are not administrative obstacles — they are contractual conditions that determine entitlement. In contracts with clear condition precedent notice clauses, there is no substitute for timely compliance. Build the notice system before the project starts.
