In the process of invalid bidding, there may be inconsistent results in the bidding documents and construction contract. After this happens, the judge is invalid. In this case, it needs to be determined according to the laws, bidding documents and contracts. It should be combined with specific problems and negotiation process of relevant supplementary agreements. The professional bidding company analyzes the difference between the bidding document and the construction contract, which is invalid.
In the practice of engineering construction project bidding, sometimes the bidding documents and bidding documents are inconsistent with the construction contract signed by the winning bidder. In this case, some people think that priority should be given to the construction contract, because the contract is an expression of will agreed by both parties through consultation; the other point is that the bidding document should be the main reason, because the bidding document is the bidder's quotation, which is the true meaning expression. When the bid winning notice is issued by the tenderee, it is the acceptance of quotation, bidding document and acceptance, so it should be the main bidder's bidding Bid documents; there are also opinions that the bidding documents should be the main reason, because according to relevant laws and regulations, the tenderee and the winning bidder shall not sign contracts that deviate from the substantive content of the bidding documents.
Interpret the order in accordance with the contract documents required by law.
The result of the inconsistency between the bidding documents and the construction contract is invalid. If the answers to some questions in this process are clarified, clear written records should be kept (to ensure that they are valid certificates). The contract terms should be modified accordingly. On the basis of this inconsistency, the contract shall prevail.
During the bidding period, if both parties have an agreement例如，有时招标文件一致认为主材料价格不调整或确认该价格，主材料价格增加的风险要承担。在协商的过程中，双方同意可以对合同进行调整。在签订合同时，有关合同条款已经修改，但投标文件不能修改。此时，双方应签署一份关于协商和调整的书面协议。
For example, sometimes the bidding documents agree that the price of main materials is not adjusted or confirmed, and the risk of price increase of main materials shall be borne. In the process of negotiation, both parties agree to adjust the contract. At the time of signing the contract, the relevant contract terms have been modified, but the tender document cannot be modified. At this time, both parties shall sign a written agreement on negotiation and adjustment.
It can be seen from the above that although the order of interpretation of contract documents is stipulated, it is necessary and important to conduct negotiations in this process. Some contract risks can be solved by forming effective agreements through negotiation.
