Mainly to check whether the settlement information reported by the construction unit is consistent with the contract, including the scope of the project, the actual amount of work completed, whether the unit price in the settlement book is consistent with the contract (whether the price adjustment is in line with the contract), and charging, etc. , including the procedures for confirming quantities and changing visas. If this kind of work is handled centrally, it will generally be completed in about 1 month.
