What kind of approval process should be adopted for the reply to the feedback of audit report?

According to Article 15 of the Measures for the Administration of Construction Contracts and Contract Valuation of Construction Projects, the employer of a construction project shall settle the project payment on a regular basis or in sections according to the progress of the project. Article 16 Completion settlement shall be handled in accordance with the following provisions: (1) After the project is completed and accepted, the contractor shall submit the completion settlement documents within the agreed time limit. (two) the employer shall give a reply within the agreed time limit after receiving the completion settlement documents. If no reply is made within the time limit, the completion settlement document shall be deemed as approval. (3) If the Employer has any objection to the completion settlement document, it shall submit it to the Contractor within the reply period, and can negotiate with the Contractor within the agreed time limit from the date of submission. (four) if the employer fails to reach an agreement with the contractor within the negotiation period or fails to reach an agreement with the contractor through negotiation, it shall entrust the project cost consulting unit to conduct the completion settlement audit. (five) the employer shall, within the agreed time limit after the expiration of the negotiation period, put forward the final settlement audit opinion issued by the engineering cost consulting unit to the contractor. If the time limit for the above matters is not clearly agreed by both parties in the contract, the agreed time limit can be considered as 28 days. If the contracting parties still have objections to the audit opinions on the completion settlement issued by the project cost consulting unit, they may apply to the construction administrative department of the local people's government at or above the county level for mediation within one month after receiving the audit opinions. If mediation fails, it may apply for arbitration or bring a lawsuit to the people's court according to law. The project completion settlement documents shall be taken as the basis of the project final accounts after being confirmed by the Employer and the Contractor. You have exceeded the inquiry period, so you should not be able to inquire about the settlement any more. According to the Interim Measures for Settlement of Construction Project Price, Chapter IV Settlement of Construction Project Price Disputes Article 18 When accepting the entrustment of the employer or the contractor, the project cost consulting agency shall prepare and review the project completion settlement, handle it carefully in accordance with the contract and the actual performance of the project, and the issued completion settlement report shall take effect after being signed by both the employer and the contractor. If one party disagrees with the report, it may apply to the relevant departments for consultation and negotiation.
