Termination is the most drastic remedy available under any construction contract, and the FIDIC forms are no exception. Bringing a contract to a premature end exposes both parties to substantial financial consequences, demobilisation costs, claims for loss of profit, and frequently protracted disputes over whether the termination was lawful in the first place. The FIDIC suite addresses termination through two parallel regimes — Clause 15, which governs termination by the Employer, and Clause 16, which governs suspension and termination by the Contractor. A wrongful termination can convert the terminating party from an aggrieved innocent into a repudiating defendant overnight, so the procedural discipline these clauses demand is not optional ceremony but the very thing that determines who wins.
The 2017 editions of the Red, Yellow, and Silver Books substantially expanded and clarified the termination provisions that had appeared in the 1999 editions. While the underlying architecture remains recognisable — Employer termination for default, Employer termination for convenience, Contractor termination for Employer default — the 2017 drafting introduces tighter notice mechanics, an entirely new “Notice of intention to terminate” step, clearer financial consequences, and important refinements to the long-criticised termination-for-convenience provisions. These changes reward careful study because the difference between a valid and an invalid termination almost always turns on procedure rather than the underlying merits.
This article examines the full termination architecture across both editions. It distinguishes termination for cause from termination for convenience, sets out the notice requirements and financial consequences applicable to each route, and offers practical guidance for Contractors, Employers, and Engineers seeking to exercise — or resist — these powerful contractual rights.
The Two Routes to Employer Termination under Clause 15
Clause 15 confers on the Employer two fundamentally different termination rights. The first is termination for the Contractor’s default under Sub-Clause 15.2, a fault-based remedy triggered by defined breaches. The second is termination for the Employer’s convenience under Sub-Clause 15.5, a no-fault right exercisable at the Employer’s discretion for any reason or no reason at all. The financial consequences of these two routes diverge sharply, which is precisely why the characterisation of any given termination matters so much.
Termination for Contractor Default — Sub-Clause 15.2
Under both the 1999 and 2017 editions, Sub-Clause 15.2 lists the grounds on which the Employer may terminate for the Contractor’s default. These include the Contractor’s failure to comply with a notice to correct under Sub-Clause 15.1, abandoning the Works or otherwise plainly demonstrating an intention not to continue performance, failing without reasonable excuse to proceed with the Works, failing to comply with a rejection notice or remedial instruction, subcontracting or assigning the whole of the Works without agreement, becoming insolvent, or engaging in corruption, collusion, or other prohibited conduct.
The 2017 edition refined these grounds in several important respects. It introduced a quantitative threshold for certain defaults — for example, where the Contractor’s failure to comply represents a substantial failure relating to the delay damages cap or the Performance Security — bringing welcome objectivity to grounds that were previously open to subjective dispute. The 2017 edition also clarified the corruption and fraud provisions in Sub-Clause 15.2.1, aligning them with multilateral development bank anti-corruption requirements.
Critically, the 2017 edition introduced a new procedural safeguard. Before terminating under most limbs of Sub-Clause 15.2, the Employer must first give a Notice of intention to terminate, specifying the matter relied upon. Termination may then follow only if the Contractor fails to remedy the matter within 14 days of that Notice. This two-stage mechanism — Notice of intention, then Notice of termination — did not exist in the 1999 edition with the same clarity, and it materially reduces the risk of a premature or procedurally defective termination. For insolvency and certain serious defaults, however, the 2017 edition permits immediate termination without the 14-day cure period.
The Notice to Correct — Sub-Clause 15.1
The notice to correct under Sub-Clause 15.1 is frequently the gateway to a Sub-Clause 15.2 termination, and the 2017 edition tightened it considerably. Under the 1999 edition, the Engineer could require the Contractor to remedy a failure within a “reasonable time”, an open-textured standard that generated disputes. The 2017 edition requires the notice to correct to specify the Contractor’s obligation and a reasonable time within which to comply, and expressly provides that the notice must not refer to insignificant matters. This protects the Contractor from a tactical accumulation of trivial notices being used to manufacture grounds for termination.
Termination for Convenience — Sub-Clause 15.5
Sub-Clause 15.5 permits the Employer to terminate the Contract for its own convenience at any time. This is a no-fault termination, and the Contractor’s entitlement on such termination is correspondingly more generous than on a default termination. The single most important protection for the Contractor — present in both editions — is the prohibition on the Employer terminating for convenience in order to execute the Works itself or to arrange for the Works to be executed by another contractor. This restriction prevents the Employer from using the convenience route as a device to remove the Contractor and then simply hand the same scope to a cheaper competitor.
The 2017 edition strengthened the financial consequences of a convenience termination. On termination under Sub-Clause 15.5, the Contractor is entitled to payment under Sub-Clause 18.5 (the valuation provision applicable to optional termination following an Exceptional Event), which includes the value of work done, the cost of plant and materials ordered, demobilisation costs, and the cost of repatriating staff and labour. Significantly, the 2017 edition addressed the long-standing controversy over loss of profit on convenience termination by providing a clearer framework, although practitioners should examine the Particular Conditions carefully because Employers frequently amend these provisions to exclude loss of profit.
Contractor Suspension and Termination under Clause 16
Clause 16 is the Contractor’s principal protection against Employer default, and it operates as a graduated remedy. The Contractor may first suspend or reduce the rate of work under Sub-Clause 16.1, and only if matters are not resolved may the Contractor proceed to terminate under Sub-Clause 16.2. This staged structure encourages resolution short of the nuclear option of termination.
Suspension by the Contractor — Sub-Clause 16.1
Under Sub-Clause 16.1, the Contractor is entitled to suspend work, or reduce the rate of work, if the Engineer fails to certify a payment, if the Employer fails to provide reasonable evidence of its financial arrangements under Sub-Clause 2.4, or if the Employer fails to pay an amount due. The 2017 edition requires the Contractor to give not less than 21 days’ notice before suspending, an important procedural prerequisite. A Contractor who suspends without the requisite notice exposes itself to a claim that the suspension was itself a breach, and the careful Contractor therefore documents the trigger, serves the notice, and waits out the notice period before downing tools.
Where the Contractor lawfully suspends under Sub-Clause 16.1, it is entitled to an extension of time for any resulting delay and to payment of Cost plus profit. The 2017 edition makes clear that these entitlements are subject to the notice and claims procedure under Clause 20, so the Contractor must still comply with the claims machinery to recover the time and money to which suspension entitles it.
Termination by the Contractor — Sub-Clause 16.2
Sub-Clause 16.2 sets out the grounds on which the Contractor may terminate. These include the Employer’s failure to provide reasonable evidence of financial arrangements, the Employer’s failure to pay amounts due within the stipulated period, prolonged suspension affecting the whole of the Works, the Employer’s substantial failure to perform its obligations, the Employer’s failure to comply with a binding DAAB decision, and the Employer’s insolvency. The 2017 edition expanded and clarified these grounds, notably adding the failure to comply with a binding dispute board decision — a powerful new lever that reflects the enhanced status of the DAAB in the 2017 suite.
As with Employer termination, the 2017 edition introduced a Notice of intention to terminate for most grounds, requiring the Contractor to give 14 days’ notice before the termination takes effect, during which the Employer may remedy the default. Certain grounds — notably Employer insolvency — permit immediate termination. This symmetry between Clauses 15 and 16 in the 2017 edition is a deliberate drafting improvement that brings procedural fairness to both sides.
Financial Consequences: The Critical Divergence
The financial consequences of termination depend entirely on the route taken, and this is where the stakes are highest. On a valid Employer termination for the Contractor’s default under Sub-Clause 15.2, the Employer may complete the Works itself or through others, may withhold further payment until costs of completion and damages are established, and may recover from the Contractor the additional cost of completing the Works together with delay damages. The Contractor’s recovery is limited to the value of work properly executed less the sums already paid and the Employer’s losses — a potentially harsh outcome that reflects the Contractor’s default.
By contrast, on a termination for the Employer’s convenience under Sub-Clause 15.5, or on a Contractor termination for Employer default under Sub-Clause 16.2, the Contractor’s recovery is significantly more favourable, typically embracing the value of work done, plant and materials, demobilisation and repatriation costs, and — subject to the Particular Conditions — loss of profit on the unexecuted balance of the Works. The gulf between these outcomes explains why so much litigation turns not on whether a termination occurred but on its proper legal characterisation.
The Repudiation Trap
A party that purports to terminate without a valid contractual ground, or without following the prescribed procedure, risks being held to have repudiated the contract. In that event the roles reverse: the purported terminator becomes the party in fundamental breach, and the other party may accept the repudiation and pursue damages. This is the single greatest danger in any termination, and it is why the procedural steps — the Notice to correct, the Notice of intention, the cure periods, and the final Notice of termination — must be followed to the letter. Under most governing laws, common law repudiation rights may also exist in parallel with the contractual termination regime, and a sophisticated party will preserve and consider both.
Practical Guidance for the Parties
For Contractors
Treat every notice as a potential exhibit in future proceedings. Before suspending under Sub-Clause 16.1, confirm the trigger is genuinely made out, serve the 21-day notice, and document the Employer’s non-payment or default contemporaneously. Before terminating under Sub-Clause 16.2, serve the Notice of intention, allow the cure period to expire, and only then serve the termination Notice. Resist the temptation to walk off site in frustration — an unlawful abandonment hands the Employer a Sub-Clause 15.2 ground. Where the Employer has failed to comply with a binding DAAB decision, recognise that the 2017 edition gives you a direct route to both enforcement and, ultimately, termination.
For Employers
Build the evidential record before terminating for default. Use the Sub-Clause 15.1 notice to correct properly, avoiding insignificant matters, and serve the Sub-Clause 15.2 Notice of intention before any termination Notice. Be especially cautious about the convenience route under Sub-Clause 15.5: it cannot be used as a device to re-let the same scope to another contractor, and an attempt to do so will likely expose the Employer to a damages claim, possibly including loss of profit. Where the Particular Conditions have amended the financial consequences of termination, ensure those amendments are clear and enforceable under the governing law, as courts in many jurisdictions scrutinise clauses excluding the Contractor’s loss of profit.
For Engineers
Although termination is ultimately the Employer’s decision, the Engineer’s role in administering the Sub-Clause 15.1 notice to correct, in certifying payments under Clause 14, and in determining claims is frequently decisive. An Engineer who fails to certify a payment due, or who issues an unjustified rejection, may inadvertently hand the Contractor a Clause 16 ground. The Engineer should administer the notice to correct fairly, document the Contractor’s failures objectively, and remain conscious that procedural missteps at the administration stage can undermine an otherwise valid termination.
Conclusion: Procedure is Substance
Termination under FIDIC is governed by a deceptively simple architecture — Employer termination for default or convenience under Clause 15, Contractor suspension and termination under Clause 16 — but the consequences of getting it wrong are severe and largely irreversible. The 2017 editions improved the position of both parties by introducing clearer notice mechanics, the staged Notice of intention to terminate, symmetrical cure periods, and refined financial consequences, while preserving the essential protection against the convenience route being abused. The enduring lesson for practitioners is that, in the law of termination, procedure is substance: the party that documents its grounds, serves the correct notices, and respects the cure periods will almost always prevail over the party that acts in haste. Before any FIDIC termination is contemplated, the relevant clause should be read alongside the Particular Conditions and the governing law, and specialist advice should be obtained, because the line between a lawful termination and a repudiatory breach is narrow and unforgiving.
