Retention: How Holdback Works and How to Actually Get It Back

Retention is the most patient thief on any construction project. It does not take money through a dispute or a rejected claim. It takes money by sitting still. The employer deducts a percentage from every interim payment certificate, holds it in a notional account, and promises to return it at two contractual milestones. The first half comes back at taking over. The second half comes back at the end of the defects liability period. In theory. In practice, contractors across the GCC are carrying QAR 2 to 8 million in unreleased retention at any given time, not because the contract prevents release, but because nobody filed the paperwork.

What Retention Actually Is and Why It Exists

Retention is a holdback mechanism. The employer withholds a percentage of each certified payment, typically 5 to 10 percent, as security against the contractor's obligation to complete the works and remedy defects. Under FIDIC 1999 Clause 14.3 and FIDIC 2017 Clause 14.3, the retention is deducted from each interim payment certificate until it reaches the limit of retention money stated in the contract data. That limit is usually 5 percent of the accepted contract amount.

The purpose is narrow and specific. Retention exists to give the employer financial leverage during the defects liability period. If the contractor fails to return and fix defects, the employer can apply the retained amount toward the cost of remedial work. It is not a performance bond. It is not liquidated damages. It is not a negotiation tool. It is a ring-fenced sum that the contract requires the employer to return, in two tranches, at defined contractual trigger points.

The first trigger is the taking-over certificate. When the Engineer issues the taking-over certificate for the whole of the works, the first half of the retention money becomes due for release. The second trigger is the expiry of the defects notification period (called the defects liability period under FIDIC 1999). When that period ends and the contractor has fulfilled its obligations, the second half becomes due. The mechanism is binary. The trigger occurs. The money is released. There is no discretion involved.

Why the Second Half Almost Never Comes Back on Time

The first half of retention is relatively straightforward. Taking over is a visible milestone. The project team is still mobilised. The QS is still active. The application for the first moiety is prepared as part of the natural close-out rhythm. It arrives late more often than it should, but it arrives.

The second half is a different problem entirely. The defects liability period on a typical GCC project runs 12 to 24 months after taking over. By the time that period expires, the project team has demobilised. The QS who managed the contract has moved to another project or another company. The contracts manager, if there was one, is long gone. The institutional memory of what retention was held, what the release conditions are, and who needs to write the letter has evaporated.

The employer, meanwhile, has no incentive to remind the contractor. The retention sits in the employer's account, earning implicit return and providing a financial buffer against any residual defects claims. If the contractor does not ask for it, the employer does not offer it. This is not bad faith. It is inertia, and inertia favours the party holding the money.

In our experience across dozens of close-out engagements, the second moiety of retention is the single largest category of money left on the table at project end, as we explored in The Cost of a Messy Close-Out: Lessons from 50+ Projects. It is earned. It is contractually due. It is simply never collected.

The Retention Release Playbook

Recovering the second half of retention is not a legal exercise. It is an administrative one. The contract tells you exactly what to do. The discipline is in doing it.

Step 1: Know the Dates

The defects notification period has a defined start date (the date on the taking-over certificate) and a defined duration (stated in the contract data, typically 365 or 730 days). Calculate the expiry date on the day the taking-over certificate is issued and calendar it. Not in a spreadsheet that nobody opens. In a system that generates an alert 90 days before expiry, 30 days before, and on the day itself.

Step 2: Perform the Defects Obligations

During the defects liability period, the contractor is obligated to return to site and remedy any defects that the employer notifies. This is not optional. Failure to attend to notified defects gives the employer grounds to withhold the second moiety or to deduct the cost of engaging others to perform the remedial work. The cheapest retention recovery strategy is to fix the defects promptly and document every attendance.

Step 3: Apply for the Performance Certificate

Under FIDIC 1999 Clause 11.9 and FIDIC 2017 Clause 11.9, the contractor is entitled to apply for a performance certificate at the end of the defects notification period. The performance certificate confirms that the contractor has fulfilled all obligations under the contract. Once issued, it triggers the release of the second moiety of retention.

The application must be in writing, addressed to the Engineer, and submitted after the expiry of the defects notification period. It should confirm that all notified defects have been remedied, reference the taking-over certificate date and the defects period duration, and request issuance of the performance certificate.

Step 4: Follow Up Relentlessly

The Engineer is required to issue the performance certificate within 28 days of the latest of the expiry of the defects notification period and the completion of all outstanding work (FIDIC 2017 Clause 11.9). If the Engineer does not issue it, the contractor must follow up. Formally. In writing. With reference to the contractual obligation and the consequence of non-issuance.

This is where most contractors fail. The letter is drafted but never sent. The follow-up is discussed but never actioned. The QAR 1.5 to 4 million sitting in the employer's account continues to sit there, earning nothing for the contractor, because nobody pressed send.

The Retention Bond Alternative

Some contracts permit or require the contractor to substitute a retention bond for cash retention. Under this arrangement, the contractor provides a bank guarantee for the retention amount, and the employer releases the cash deductions. The contractor pays a bank fee, typically 1 to 2 percent per annum of the guarantee value, but recovers the cash flow that retention would otherwise consume.

The economics are straightforward. On a QAR 60 million contract with 5 percent retention, the maximum retention is QAR 3 million. A retention bond at 1.5 percent costs QAR 45,000 per year. The contractor recovers QAR 3 million in cash flow for QAR 45,000 in annual bank charges. For any contractor managing working capital carefully, as described in Interim Payment Certificates Explained: The Monthly Valuation Cycle Every Contractor Should Master, the trade is obvious.

Not all employers accept retention bonds. FIDIC 1999 Clause 14.9 provides that the employer shall return retention against a guarantee, but many GCC employers amend this clause in the particular conditions to remove or restrict the substitution right. The contractor should check the particular conditions at tender stage. If the substitution right exists, exercising it early protects cash flow throughout the project rather than waiting for the slow mechanics of retention release at the back end.

What Happens When the Employer Refuses to Release

Occasionally, the employer withholds the second moiety despite the contractor fulfilling all obligations. The grounds cited are usually outstanding defects (whether genuine or disputed), incomplete documentation, or simply administrative delay. The contractor's response should follow a defined escalation path.

First, write to the Engineer identifying the contractual basis for release, confirming that all defects have been remedied, and requesting issuance of the performance certificate. If no response is received within the contractual period, escalate to the employer directly with a copy of the correspondence trail. If the employer continues to withhold, the contractor's recourse is through the dispute resolution mechanism in the contract, whether that is a DAAB referral under FIDIC 2017 or direct arbitration under FIDIC 1999.

The amounts justify the effort. QAR 1.5 million in unreleased retention on a single project is not a rounding error. Across a portfolio of three completed projects, unreleased second moiety retention can exceed QAR 5 million. That is working capital the contractor earned, the employer is holding without contractual basis, and the contractor can recover through a process that is procedural, not adversarial.

The Retention Tracker as a Commercial Tool

CALIM builds a retention tracker into every contract administration engagement. The tracker records the retention deducted from each interim payment certificate, the cumulative retention held, the taking-over date, the defects notification period expiry, and the status of both moiety releases. It generates alerts before each release milestone and prompts the formal application process at the appropriate time.

The tool is simple. The discipline it enforces is the difference between recovering your retention and forgetting it exists. At CALIM, we treat retention as earned revenue with a deferred collection date, not as money that might come back if someone remembers to ask.

Retention that is not tracked is retention that is not recovered.

Frequently Asked Questions

What is the typical retention percentage on a FIDIC contract?

The retention percentage is stated in the contract data and typically ranges from 5 to 10 percent of each interim payment, subject to a limit of retention money that is usually 5 percent of the accepted contract amount. The specific percentage depends on the contract and the employer's requirements. Once the cumulative retention reaches the stated limit, no further deductions are made from subsequent interim payments.

When is the second half of retention released under FIDIC?

The second moiety of retention is released upon issuance of the performance certificate, which the Engineer issues after the expiry of the defects notification period and the contractor's completion of all outstanding obligations. Under FIDIC 2017 Clause 11.9, the Engineer must issue the performance certificate within 28 days of the latest of these two events. The contractor should apply formally in writing once the defects notification period expires.

What is a retention bond and should I use one?

A retention bond is a bank guarantee that the contractor provides to the employer in substitution for cash retention. The employer releases the cash deductions, and the contractor pays a bank fee, typically 1 to 2 percent per annum of the guarantee value. The advantage is improved cash flow throughout the project. The decision depends on whether the contract permits substitution (check FIDIC Clause 14.9 and the particular conditions) and whether the cost of the bank guarantee is justified by the cash flow benefit on the specific project.

What can I do if the employer refuses to release retention after the defects liability period?

If the employer withholds retention despite the contractor fulfilling all defects obligations, the contractor should write formally to the Engineer requesting issuance of the performance certificate with reference to the specific contractual clause. If no response is received within the contractual timeframe, escalate to the employer directly. If the employer continues to withhold without contractual basis, the contractor's recourse is through the dispute resolution mechanism specified in the contract, whether DAAB referral, arbitration, or other prescribed procedure.

How do I prevent retention from being forgotten at project close-out?

Build a retention tracker at the start of the project, not at the end. Record every retention deduction from every interim payment certificate. Calendar the taking-over date, the defects notification period expiry, and the target dates for first and second moiety release applications. Assign responsibility for the release application to a named individual and ensure handover documentation includes the retention status if project personnel change during the defects liability period.

Note: This article provides general guidance on retention mechanics and release procedures under FIDIC contract forms. The specific retention provisions, release triggers, and substitution rights depend on the contract edition, the particular conditions, and any amendments applied. Contractors should review the specific terms of their contract and seek professional advice where retention release is disputed or delayed.
