It only needs to return the amount received, and does not need to return double the amount.
2. The provisional amount refers to a sum of money tentatively determined by the tenderer in the bill of quantities and included in the contract price. It is used for the procurement of required materials, equipment, and services that have not yet been determined or unforeseen when the construction contract is signed, project changes that may occur during construction, project price adjustments when adjustment factors agreed in the contract occur, and claims that occur, on-site visa confirmation, etc. cost. The provisional amount is the owner's reserve fund, which will only be used when a change claim occurs. It does not constitute a project entity. In principle, expenses that do not constitute a project entity are not used as the basis for calculating the advance payment.

Waiting costs. The provisional amount generally shall not exceed the 20.10 version of the estimated total cost. The provisional amount is all expenses except taxes. When the project is settled, the provisional amount should be canceled, and additional expenses will be added based on the actual project costs.
4. The formula for advance payment is: T=P-M/N.
(1) In the formula, T is the starting deduction point, that is, the cumulative value of the completed project when the prepayment of the project starts to be deducted;
(2) M is the total amount of prepayment for the project ;
(3) N is the proportion of main materials and important components in the project payment;
