Performance Guarantee Requirements for Government Contracts

Winning a government tender is the start of a contract, not the end of the process. Within a short time of receiving the letter of acceptance, most successful bidders must provide a performance security before the contract can be signed. In practice, this almost always means a bank-issued performance guarantee. A performance guarantee in Sri Lanka, as in most countries, protects the procuring entity if the contractor fails to perform. It also ties up part of your credit limit for months or even years. If you misunderstand it, you can lose the contract you just won, or run into cash-flow strain during delivery.

This guide explains what a performance guarantee in Sri Lanka involves for government contracts, how the requirement is usually set, what the bank will need, how to check the wording, and how the guarantee is extended, reduced, called or released.

Note: Performance security amounts, forms, deadlines and release conditions are set in each tender's bidding documents and contract conditions. Always verify them in the specific documents and with your bank.

What Is a Performance Guarantee?

A performance guarantee (also called performance security or performance bond) is an undertaking, usually by a bank, to pay the employer up to a stated amount if the contractor fails to fulfil its contractual obligations.

It differs from other securities you may meet in public procurement:

| Security | Purpose | When provided | |---|---|---| | Bid security | Ensures bidder honours its bid | With the bid | | Performance security | Protects employer against non- performance | After award, before or at contract signing | | Advance payment security | Protects advance payments made to contractor | Before advance is paid | | Retention money / retention guarantee | Covers defects after completion | Deducted from payments, or replaced by a guarantee where permitted |

Performance Guarantee in Sri Lanka: Where the Requirement Comes

From

In Sri Lanka, government procurement follows the procurement guidelines issued by the National Procurement Commission (NPC), including the Procurement Guidelines 2024 for Goods and Works, together with the standard bidding documents used by procuring entities. These set the general framework. The details for each contract are then fixed in:

• The Instructions to Bidders and Bid Data Sheet, which tell bidders that a performance security will be required
• The Particular Conditions of Contract, which set the amount, form and validity
• The contract forms section, which contains the required performance security format

For works contracts, conditions are often based on standard contract forms, adapted by the procuring entity. For goods, the conditions in the standard bidding documents for goods apply. Always read the specific documents rather than relying on what a previous contract required.

Typical Features of the Requirement

The exact figures vary, so treat the points below as general features to look for, not fixed rules.

Amount

The performance security is usually expressed as a percentage of the contract price, stated in the bidding document or contract conditions. Larger or more complex contracts may have different requirements from small supply contracts. Some low-value contracts may not require one at all. Confirm the percentage or amount in each document.

Form

Acceptable forms are listed in the contract documents. Common options include:

• Unconditional bank guarantee from a licensed commercial bank
• Guarantee or bond from another institution, if the document allows it
• Other instruments, only if specifically listed

The guarantee must follow the format in the bidding document.

Deadline for submission

The letter of acceptance will normally give a short period, stated in the bidding document, within which you must sign the contract and submit the performance security. Failing to do so can lead to the award being cancelled and your bid security being called.

Validity

The guarantee usually needs to remain valid until a specified time after completion, for example beyond the intended completion date or until the end of the defects liability or warranty period, depending on the contract. If the contract is extended, the guarantee may need to be extended too.

Step-by-Step: Getting a Performance Guarantee

1. Prepare before you bid

Do not wait for the award letter. When deciding to bid, check:

• The likely performance security amount
• Whether your bank facility has enough headroom for the bid security and the performance security, plus any advance payment security
• What collateral the bank may want

Talk to your bank early so it can approve or increase your guarantee limit in good time.

2. Receive the letter of acceptance

Read it carefully. Note the contract price, the deadline for the performance security and the contract signing date.

3. Send clear instructions to the bank

Give your bank:

• A copy of the letter of acceptance
• The performance security format from the bidding document
• The exact beneficiary name and address
• Amount in figures and words, and currency
• Required expiry date

4. Check the draft

As with a bid security, check:

• Wording matches the required format, with no extra conditions
• Names, contract reference, amount and dates are correct
• Expiry date meets or exceeds the requirement

5. Submit and get acknowledgement

Submit the original as instructed, sign the contract, and get written acknowledgement. Your bid security will then normally be released.

What Banks Usually Require

Banks treat a performance guarantee as a credit exposure, because they may have to pay out if you fail to perform. Typical requirements include:

• An approved guarantee facility or a separate credit application
• Counter-indemnity from your company and sometimes personal guarantees from directors
• Financial statements and information on the contract
• Collateral or a cash margin, depending on your credit profile
• Payment of commission, often based on amount and period

Because performance guarantees often run for long periods, the total commission can be significant. Include this cost in your tender pricing.

Illustrative Example

The numbers below are hypothetical and rounded, purely to show the calculation.

Suppose a works contract is awarded at LKR 100,000,000, and the bidding document requires a performance security of 5% of the contract price, valid until 28 days after the end of the defects liability period.

| Item | Example figure | |---|---| | Contract price | LKR 100,000,000 | | Performance security (example 5%) | LKR 5,000,000 | | Contract duration (example) | 12 months | | Defects liability period (example) | 12 months | | Approximate guarantee period | Around 25 months |

The contractor would need a bank facility covering LKR 5,000,000 for about two years and should include the related commission in its price. The 5% figure here is only an example. Use the figure stated in your contract.

When Can the Guarantee Be Called?

The employer can usually demand payment if the contractor fails to fulfil its obligations under the contract, as described in the contract conditions and the guarantee wording. Many guarantees are "on first demand", which means the bank pays when it receives a valid demand that complies with the guarantee's terms, without first deciding whether the contractor was actually at fault.

That is why it matters to:

• Perform the contract and keep good records of progress, instructions and variations
• Communicate in writing with the engineer or project officer
• Raise disputes through the contract's dispute resolution procedure promptly
• Seek legal advice early if a call seems likely

Extensions, Reductions and Release

Extensions

If completion is delayed or the contract is extended, the employer may ask you to extend the performance guarantee. If an extension is not arranged before expiry, some contracts allow the employer to call the guarantee. Monitor expiry dates closely.

Reductions

Some contracts allow the guarantee amount to be reduced at certain stages, for example after taking-over or after part of the works is completed. This only applies where the contract says so.

Release

Once the conditions for release are met, typically after completion and the end of any defects or warranty period, the employer returns the guarantee or confirms release in writing. Give the original back to your bank to close the liability and stop charges.

Common Problems and How to Avoid Them

| Problem | How to avoid it | |---|---| | Missing the submission deadline after award | Pre-arrange bank facility during bidding | | Wrong amount because of a price correction | Calculate from the final accepted contract price | | Guarantee expires during contract extension | Keep a guarantee register with expiry alerts | | Bank wording adds conditions | Insist on the bidding document format | | Unexpected collateral demand | Discuss collateral with the bank before bidding | | Commission not priced into the bid | Include guarantee costs in overheads |

Key Takeaways

• A performance guarantee in Sri Lanka's public contracts protects the employer if the contractor fails to perform.
• The amount, form, deadline and validity are set in each contract's documents. Check them every time.
• Arrange your bank facility during bidding, not after award.
• Make sure the wording, names, amount and expiry match the required format exactly.
• Track expiry dates and extend in time if the contract is extended.
• Include guarantee commission in your price, and close the liability once released.

Frequently Asked Questions

What percentage is the performance security in Sri Lankan government contracts?

It varies by contract and is stated in the bidding document or contract conditions. Always use the percentage or amount specified for your contract rather than a general figure.

How soon after award do I need to provide the performance guarantee?

The letter of acceptance and the bidding document state the deadline, which is usually short. Failing to meet it can result in cancellation of the award and the calling of your bid security.

Can I use an insurance bond instead of a bank guarantee?

Only if the contract documents list it as acceptable. Check the permitted forms of performance security in the Particular Conditions of Contract.

When is the performance guarantee returned?

It is normally released after the contractor completes its obligations, often after the defects liability or warranty period, as set in the contract. Some contracts allow partial reduction earlier.

What happens if my performance guarantee expires before the contract ends?

You may be in breach of contract, and some contracts allow the employer to call the guarantee if it is not extended before expiry. Arrange extensions early.

Does a small supply contract always need a performance guarantee?

Not always. Requirements depend on the contract value, type and the procuring entity's documents. Check each bidding document.

Conclusion

A performance guarantee is a normal part of government contracting in Sri Lanka, but it is not a formality. It ties up credit, costs money and can be called if things go wrong. Plan it during bidding, check every detail against the contract documents, and manage it actively until release. Doing so protects both your contract and your cash flow.
