After the project is completed, how to check the quantities and unit prices in the Final Account of Construction Project provided by the constructor?

First, check the unit price and compare it with the contract and budget:

1. If the contract stipulates that the unit price is not adjusted, then the unit price can only be based on the budgeted unit price;

2. If the unit price is allowed to be adjusted according to the contract, it shall be adjusted by referring to the price adjustment method agreed in the contract; If the price adjustment method is not stipulated in the contract, it is a bit troublesome to negotiate with the construction party;

3. If a project is not included in the budget due to changes, there are three ways to determine the unit price of the project. You can look at the FIDIC contract terms, which are very simple;

On the audit of engineering quantity:

1, review and compare the engineering measurement list signed by all parties;

2, check all kinds of change files;

3, the project site measurement;

Because I don't know what your project is, I can't be specific.
