The specific amount of the performance bond shall be determined according to the proportion of 5- 10% of the bid price. The specific amount of the deposit is determined according to the difference between the maximum price limit and the bid price.

The performance bond collection standard should follow several principles:

First, the amount of performance bond should wait for the advance payment of the contract to reflect the principle of fairness stipulated in the contract law;

Second, the amount of the performance bond has nothing to do with the bid bond. According to the bidding law, the bid bond is generally 2% of the bidding control price, and the maximum amount shall not exceed 800,000 yuan; The performance bond is generally 5%- 10% of the contract amount.

Generally speaking, the amount of performance bond will be higher than the bid bond. After the winning bidder is determined, the two parties sign a contract, and the bid bond of the winning bidder can be converted into a performance bond, and the insufficient part will be made up by the winning bidder.

If a bidder gives up his bid within the validity period of the bid or gives up after winning the bid, the tenderer may confiscate all his bid bond, but not his performance bond.

Third, the determination of the amount of performance bond should be linked to the payment terms of the contract, and the performance bond is generally returned simultaneously with the progress payment.
