FIDIC Clause 14.9: Retention Release Explained
Retention is the most contested payment provision in FIDIC contracts. Contractors fund it from day one, Employers hold it for months or years, and disputes around release are routine on projects of every scale. The standard form position under Sub-Clause 14.9 is clear enough: half on Taking-Over, half after the Defects Notification Period. In practice, Particular Conditions modify the release conditions in ways that place both tranches firmly within the Employer's control, and the result is retention sitting on completed projects long after any commercial justification for holding it has expired.
This guide covers what Sub-Clause 14.9 requires, how the two-stage mechanism works, how Particular Conditions modify it, and the disputes that arise most commonly around release.
What Clause 14.9 Requires
Sub-Clause 14.9 establishes the Employer's obligation to release the Retention Money that has been deducted from Interim Payment Certificates throughout the contract. Retention is deducted from each IPC under Sub-Clause 14.3 at the rate stated in the Appendix to Tender, typically 5 percent of each certified amount, up to a stated limit, typically 5 percent of the Contract Price.
The Retention Money is not a bonus held by the Employer. It is money that belongs to the Contractor, deducted from payments already certified by the Engineer, held by the Employer as security against defects and incomplete work. Sub-Clause 14.9 defines the conditions under which the Employer is obliged to release it.
The standard FIDIC position establishes two release tranches, each triggered by a specific contractual milestone. The first tranche is released when the Taking-Over Certificate is issued under Clause 10. The second tranche is released when the Defects Notification Period expires and any outstanding defects have been corrected. In both cases, the Engineer includes the released amount in the next Interim Payment Certificate or, for the final tranche, in the Final Payment Certificate under Sub-Clause 14.13.
The mechanism is designed to give the Employer security against the risk it faces at each stage: before completion, the security is the full Retention Money; after Taking-Over, the remaining risk is defects during the Defects Notification Period, and half the retention is sufficient security for that risk; after the DNP expires, the Employer's risk under the contract is largely extinguished and the remaining retention is released.
The Two-Stage Release Mechanism
The first tranche, typically half the total Retention Money, is released when the Engineer issues the Taking-Over Certificate for the works or a section. The release is not discretionary. When the Taking-Over Certificate is issued, Sub-Clause 14.9 requires the Engineer to include the first tranche in the next IPC. The Employer then pays it under Sub-Clause 14.7 within the payment period applicable to that IPC.
The trigger is the Taking-Over Certificate, not practical completion or substantial completion as those terms are sometimes used informally. Under FIDIC, Taking-Over is a formal contractual milestone evidenced by the Engineer's certificate. Until the certificate is issued, the retention remains fully held.
The second tranche is released when the Defects Notification Period expires and the Engineer issues the Performance Certificate under Sub-Clause 11.9. The DNP is stated in the Appendix to Tender and typically runs for 12 months from the Taking-Over Date. The Performance Certificate confirms that the Contractor has fulfilled all obligations under the contract, including the correction of defects notified during the DNP.
Once the Performance Certificate is issued, Sub-Clause 14.9 requires the remaining Retention Money to be included in the Final Payment Certificate. The Final Payment Certificate is issued under Sub-Clause 14.13 following the submission of the Final Statement by the Contractor.
The practical timeline for full retention release on a standard FIDIC project is therefore: contract award, deductions begin on the first IPC, Taking-Over Certificate issued at completion of the works, first tranche released, DNP runs for 12 months, Performance Certificate issued, second tranche released via Final Payment Certificate. On a project with a 24-month construction period and a 12-month DNP, the second tranche of retention can be held for 36 months or more from the date of the first deduction.
How Particular Conditions Modify Retention
The standard form position is rarely what applies on bespoke FIDIC contracts. Particular Conditions modify retention release in several ways, and the modifications almost always extend the Employer's control over when release occurs.
Additional conditions on the first tranche. The standard form releases the first tranche when the Taking-Over Certificate is issued, with no additional conditions. Particular Conditions frequently introduce requirements that must be satisfied before or alongside the Taking-Over Certificate before the first tranche is released: submission of as-built drawings, submission of operation and maintenance manuals, or handover of health and safety files. In practice, these conditions shift the effective release date from the Taking-Over Date to whenever the Employer or Engineer is satisfied with the additional documentation, which can be months after the works are complete.
Performance Certificate as the trigger for the second tranche. The standard form releases the second tranche when the DNP expires and the Performance Certificate is issued. The Performance Certificate is issued by the Engineer, and its issuance is conditioned on the Contractor having corrected all notified defects. Particular Conditions sometimes make the second tranche release conditional on the Performance Certificate being issued, rather than merely on the DNP expiring, and then introduce additional conditions on the Performance Certificate itself: all defects corrected to the Engineer's satisfaction, all outstanding claims resolved, and all final accounts agreed. Each condition is an additional lever by which the Employer can delay the Performance Certificate and, with it, the second tranche of retention.
Retention percentage above the standard position. The standard Appendix position is 5 percent retention up to a limit of 5 percent of the Contract Price. Particular Conditions on high-risk or complex projects sometimes increase the retention percentage, the limit, or both. A 10 percent retention rate deducted up to a cap of 10 percent of the Contract Price doubles the cash held by the Employer throughout the project and doubles the financing cost to the Contractor.
Employer set-off against retention. Some Particular Conditions include provisions allowing the Employer to apply retention against costs incurred as a result of the Contractor's defaults or against liquidated damages. These provisions can prevent retention release even where the standard conditions for release have been met, by permitting the Employer to make deductions from the retention fund before releasing it.
Resolution of all outstanding claims as a condition of release. A provision that makes retention release conditional on all claims being resolved places the Employer in a position to delay release indefinitely by keeping a single claim open. This provision is particularly damaging on projects where the Employer and Contractor have a live dispute, because the Employer can effectively use the retention as leverage in the claims negotiation.
Common Disputes Around Retention Release
The disputes that arise most frequently around FIDIC retention involve the same patterns across different projects and jurisdictions.
The most common is delay in issuing the Taking-Over Certificate. Since the first tranche of retention is released on Taking-Over, any delay in the Engineer issuing the certificate directly delays the release. The Engineer's obligation to issue the Taking-Over Certificate is governed by Sub-Clause 10.1, which requires the certificate to be issued within 28 days of the works being substantially complete. Disputes arise where the Employer or Engineer disputes whether the works meet the completion criteria, or where the Employer instructs the Engineer not to issue the certificate pending resolution of other matters.
The second common dispute concerns additional conditions in Particular Conditions. Where retention release is conditional on submission of documentation, and the Employer rejects successive submissions on minor grounds, the Contractor's claim is that the Employer is artificially preventing a condition from being satisfied. This is a breach of the Employer's obligation to act in good faith in the performance of the contract, and it gives rise to a claim under Clause 20.
The third dispute pattern involves the scope of defects that the Employer can use to withhold the second tranche. The standard form releases the second tranche when the DNP expires and the Performance Certificate is issued. Some Employers refuse to issue the Performance Certificate on the basis of minor or disputed defects, or defects that were not properly notified during the DNP. A dispute then arises about whether the Employer has a genuine right to withhold release, or whether the refusal to issue the Performance Certificate is itself a breach.
In all these cases, the Contractor's primary tool is the claim under Clause 20 for the amount wrongly withheld, plus financing charges under Sub-Clause 14.8 on the amount from the date it should have been released. The notice requirements under Clause 20 apply to these claims in the same way as to any other entitlement claim. For detail on how Clause 20 notice requirements operate and the condition precedent consequences of missing them, see the guide to FIDIC Clause 20 notice requirements.
How AI Reviews Clause 14.9 Modifications
AI review of Sub-Clause 14.9 identifies every modification to the standard retention mechanism and explains the commercial consequence. The analysis covers the retention rate and limit, the conditions attached to each tranche, and any set-off provisions or additional requirements introduced in Particular Conditions.
For the first tranche, AI identifies whether additional documentation conditions have been introduced alongside the Taking-Over Certificate and whether those conditions are within the Contractor's control or require third-party acceptance. For the second tranche, AI identifies whether the Performance Certificate conditions have been expanded beyond the standard form position, and whether claim resolution or account agreement provisions have been added that could indefinitely delay release.
AI also reads Sub-Clause 14.9 alongside Sub-Clause 14.6 to give a complete picture of the payment timeline. The first tranche is released via an IPC under the same mechanism as any other certified payment: once the condition is met, the Engineer includes the amount in the next IPC, and the Employer pays within the Sub-Clause 14.7 payment period. For detail on how Sub-Clause 14.6 operates and how Particular Conditions modify the IPC mechanism, see the guide to FIDIC Clause 14.6 and the Interim Payment Certificate.
The output of AI retention analysis is a plain-English summary of what the modified Sub-Clause 14.9 requires: which conditions must be met before each tranche is released, who controls those conditions, and what the Contractor's exposure is if the conditions are manipulated to delay release. This is the information a commercial manager needs at tender stage to decide whether the retention provisions are acceptable as drafted or require negotiation.
Frequently Asked Questions
When is retention released under a FIDIC contract?
Under the standard FIDIC position in Sub-Clause 14.9, retention is released in two tranches. The first half is released when the Engineer issues the Taking-Over Certificate for the works or a section, and is included in the next Interim Payment Certificate. The second half is released when the Defects Notification Period expires and the Engineer issues the Performance Certificate confirming that all defects have been corrected, and is included in the Final Payment Certificate. Particular Conditions frequently modify these release conditions, attaching additional requirements to each tranche that can extend the release date significantly beyond the standard form position.
What is the standard retention percentage in FIDIC contracts?
The standard position in FIDIC is a retention rate of 5 percent deducted from each Interim Payment Certificate, with a maximum limit of 5 percent of the Contract Price. These figures are stated in the Appendix to Tender and are the starting position for negotiation. Particular Conditions sometimes increase both the rate and the limit on projects with higher perceived risk, and occasionally provide for a reduction in the rate after a stated proportion of the contract has been completed.
Can the Employer withhold retention after the Defects Certificate is issued?
Under the standard FIDIC form, once the Defects Notification Period has expired and the Performance Certificate has been issued, the Employer's contractual entitlement to hold the retention fund is exhausted. The remaining Retention Money is released via the Final Payment Certificate. The Employer can make a deduction from the Final Payment Certificate if they have a valid Clause 20 claim, but they cannot withhold the retention itself on the basis of matters arising after the Performance Certificate. Particular Conditions sometimes modify this by allowing the Employer to retain funds pending resolution of disputes, but any such provision should be identified and its commercial effect assessed at tender stage.
How do Particular Conditions typically change the retention release conditions?
The most common Particular Conditions modifications to Sub-Clause 14.9 are: adding documentation submission requirements (as-built drawings, O&M manuals) as conditions to the first tranche release alongside the Taking-Over Certificate; making the second tranche conditional on a Performance Certificate that has additional requirements beyond defect correction; introducing claim resolution or final account agreement as conditions to the second tranche; and including set-off provisions that allow the Employer to apply the retention fund against costs or damages before releasing it. Each of these modifications extends the Employer's control over the release date.
What happens if the Engineer fails to certify the retention release?
If the conditions for retention release under Sub-Clause 14.9 have been met and the Engineer does not include the retention in the next IPC or Final Payment Certificate, the Contractor has a claim for the amount and for financing charges under Sub-Clause 14.8 from the date the amount should have been certified. The claim is brought under the Clause 20 procedure, with the same notice requirements as any other entitlement claim. The Contractor should give notice promptly when the certification deadline passes without the retention being released, creating a contemporaneous record of the breach and preserving the entitlement to financing charges.
