A Tender Bid Security or Bid Guarantee is a financial instrument that ensures a bidder’s commitment to the tender process. It is typically required by the entity inviting tenders (the procuring authority) to protect against the risk of the bidder withdrawing their bid, failing to sign the contract, or failing to provide performance guarantees once the contract is awarded.

Here’s an overview of how it works and its significance:

1. Purpose of Tender Bid Security

• Assurance of seriousness: The bid security acts as a guarantee that the bidder will honor their bid and, if awarded the contract, will enter into an agreement and provide the required performance guarantees.
• Prevents frivolous or speculative bids: The requirement discourages bidders from submitting bids without the intention or ability to execute the contract.
• Compensates for costs: If a winning bidder fails to enter into the contract, the bid security helps to compensate the procuring authority for the time, effort, and administrative costs involved in processing the tender and re-issuing it.

2. Form of Bid Security

• Bank Guarantee: A promise by the bidder’s bank to pay a specific amount if the bidder defaults.
• Bid Bond: A type of surety bond provided by an insurance company or a bank, ensuring payment in case of default.
• Cash Deposit: Some entities accept direct cash deposits as a form of security, though this is less common.
• Letter of Credit: In some cases, a letter of credit from a bank may serve as bid security.

3. Amount of Bid Security

• The bid security amount is typically a percentage of the total value of the tender, often ranging from 1% to 5%of the contract value. The exact amount and conditions are specified in the tender documents.
• For large-scale projects or high-risk contracts, the bid security could be higher, and for small or low-risk contracts, it might be lower.

4. Conditions for Release

• Unsuccessful bidders: Once the tender process concludes and the contract is awarded to the successful bidder, the bid security for unsuccessful bidders is typically returned, usually within a specified period.
• Successful bidder: The bid security of the successful bidder is often refunded once they have signed the contract and/or provided the performance bond or guarantee.
• Non-compliance or withdrawal: If the bidder withdraws their bid or fails to meet the requirements stipulated in the tender, the bid security may be forfeited as compensation to the procuring authority.

5. Forfeiture

• If a bidder fails to honor the terms of their tender submission (e.g., withdrawing their bid after submission or failing to sign the contract within a specified period), the bid security may be forfeited.
• The forfeiture typically compensates the procuring authority for the inconvenience, administrative costs, and any losses incurred as a result of the bidder’s failure to comply.

6. Legal Framework

• In many jurisdictions, the rules regarding bid securities are governed by public procurement regulations, laws, or guidelines to ensure fairness, transparency, and to prevent abuse in the tendering process.

7. Duration

• The bid security remains valid for a specified period, typically 30 to 90 days after the opening of the tender. This duration is sufficient to ensure the bidder does not back out once the tender evaluation process is underway.

8. Example

• If a company bids for a construction project worth $10 million and the tender documents require a 2% bid security, the company would need to provide a bid security of $200,000. If the company is awarded the contract and signs it, the bid security is returned. If the company withdraws or refuses to sign the contract, the $200,000 bid security is forfeited.

In summary, the tender bid security/guarantee protects the interests of the entity inviting the bids and ensures the seriousness of the bidders. It’s an important financial instrument in many public and private procurement processes.
