The pricing method of the tender documents is different from that of the construction contract.

The tenderer and the winning bidder shall conclude a written contract with the bidding documents of the winning bidder according to the bidding documents, and the two parties shall not conclude other agreements that deviate from the substantive contents of the contract. Therefore, the written contract price signed by the tenderer and the bidder should not be changed in principle. If the project is a project that must be tendered according to law, the contract signed by both parties shall be settled according to the recorded contract.
