Cause of the problem: The so-called \"malicious low-price bidding\" means that when the bidding document adopts the \"minimum bid price method after review\" or the \"comprehensive scoring method\" and the price weight is large, the bidder maliciously lowers the bid price or colludes with other bidders to jointly bid at a price lower than the cost in order to win the bid, so that his bid price is closer to the benchmark price of bid evaluation. The act of artificially raising its price score to seize the chance of winning the bid.

\"Malicious low-price bidding\" is usually the application of the bidder's bidding strategy of \"winning the bid at a low price and claiming the compensation at a high price\". The bidder first uses \"low price\" as the bait and means to snatch the opportunity of winning the bid. During the contract performance period after winning the bid, the bidder (the winning bidder) will often show his hand to the owner unit, emphasize its difficulties in performing the contract for various reasons, and ask for additional contract price. To make up for their unreasonably low prices. If the owner unit fails to meet the requirements of the bidder (winning bidder), the bidder (winning bidder) usually adopts the following countermeasures:
1. Replace the pillar, shoddy, provide shoddy goods, services and projects, reduce project costs and create profit space at the expense of project quality.
2. Deliberately delaying the progress of the project or the delivery and service time, maliciously increasing the pressure on the progress of the owner's unit and forcing the owner's unit to compromise.
3. Create conditions for rescission of the contract, artificially and maliciously terminate the contract in advance to reduce its performance cost, force the owner to re-select the construction unit, supplier or service provider, and seriously affect the progress of the project.
Solution to the problem: Through the analysis of bidding documents and online access to relevant information, the main ideas for solving this are the following:
< br \/ >
1. Low price risk: In order to prevent the occurrence of low bid price, due to rising prices or other reasons during the performance of the contract contract of the winning bidder to break the deposit.
2. Performance bond: Prevent the winning bidder from violating the contract provisions or breaching the contract during the execution of the contract, and make up for the economic losses caused to the bidder.
3. The bid evaluation method is refined, and the list price is reviewed, such as the key project review, the release of the review price, how much lower than the cost price is to do scrap bid processing, mainly the review price is high and a lot of subprojects, the main material class, and the price is determined in a reasonable line.
4. When setting the bid evaluation method, you can average the price of multiple bids and set the benchmark value, which is higher than the benchmark value and is closest to the first winning bidder.
5. Prepare the bill of quantities budget and the upper limit control price, to give a reasonable profit margin and must be professional, to facilitate the competition of bidders.
6. Adopt pre-qualification, select the best units with strong comprehensive strength to bid.
Set up corresponding clauses in the tender and contract to bind the bidder. For example, strengthening supervision and management in the construction process. The tenderer may require the successful tenderer to strictly comply with the requirements of the standard specifications for construction, to prevent shoddy manufacturing and cutting corners, resulting in inferior quality.
If we want to prevent the malicious low bid, the key link is still to start with the bid evaluation. Because it is a project tender, there are still more means that can be taken.
1, the bid evaluation method is refined, the list price is reviewed, such as the key project review, the release of the review price, less than how much is lower than the cost price to do scrap bid processing, mainly review the price of a large number of sub-projects, the main material class, to ensure that the price is reasonable line.
2, the bid evaluation method should pay attention to the setting, to average the price of a number of bids, set a benchmark value, higher than the benchmark and the closest to the first bidder, to give you a common method on our side of the business bid evaluation method:
Step 1: The tenderer announces the upper limit control price of the project to all bidders three days before the bid deadline. If the bidder's bid price is less than the upper limit control price prepared by the tenderer, it is a qualified bid price. If the bidder's bid price is greater than or equal to the upper limit control price prepared by the tenderer, it is an invalid bid price, and the bid document is invalid. No follow-up review.
Step 2: Detailed evaluation of business bids: The bid evaluation committee will conduct detailed evaluation of business bids in accordance with the bidding document evaluation methods. Do not participate in the follow-up review.
