Suggestions on the problem of effectively curbing the problem of low -priced bidding for water conservancy projects

The Zigong City Audit Bureau of Sichuan Province conducted a decision -making and deployment of the provincial and municipal water conservancy development planning and decision -making, and took the "water conservancy project to make up for shortcomings and strong supervision services for the water conservancy industry" as the entry point of the audit supervision. Essence The audit survey revolved around the city's water conservancy development planning and implementation situation and the promotion of major water conservancy projects during the "Thirteenth Five -Year Plan" period, focusing on the city's four large and medium -sized water conservancy project construction management and investment control situations in the "13th Five -Year Plan" water conservancy development plan. Essence In the analysis of the bidding quotation of the bidder, the audit survey found that there is a loophole in the preparation of the construction bidding documents and the construction unit of the construction unit in Sichuan Province. The risk of outdooring of engineering investment management.

1. Main question

When the bidding of the water conservancy engineering bidder exceeds the control price, the corresponding unit price is more ± 25%of the sub -items. The unbalanced quotation is used to win the market at a low price. It is particularly prominent than other industries. The main reason is that there are vulnerabilities in the bidding documents prepared by the bidder. Highlights include:

(1) The construction process of the list project is not adapted to the scene. A reservoir dried canal one section of the stone square hole excavation (drilling method) sub -item control price comprehensive unit price of 250.63 yuan/m3, the bid price of the bidder is 44.47 yuan/m3, the total floating total amount of 5.461 million yuan 37.82%, the unit price of the bid is far lower than the normal cost price. As an experienced contractor, the cost input required for the sub -item should be fully aware of the cost of the sub -item, and the quotation should be regarded as a malicious imbalance. During the construction period, the bidder repeatedly used the use of drilling methods at the construction site to lead to villagers' resistance, maintaining stability, and accelerating project construction, and proposed to change the explosion method to the digging method, and then change the sub -price. Too large, the construction unit dare not make decisions easily, so the project progress is very slow.

(2) The amount of list project is seriously error. The design drawings of a certain irrigation dry canal project reflect that the volume of C20 concrete frame grid beams is 14m3, C25 concrete (cave body) project volume is 11,126m3, and the actual bidding document volume list, C20 concrete frame grid construction drawing engineering volume is 11,126 M3, C25 concrete (cave body) construction drawing engineering volume is 14m3. The bidder used the bidding list project to error the loopholes to quote the C20 concrete frame grid beam. Compared with the control price, the list is reduced by 107.452 million yuan; The offer is 1157.16 yuan/m3, the unit price floats 191.39 yuan/m3, and the floating rate is 19.82%. The bidder will make a zero quotation of the actual amount of actual projects, and the profit of the total bid price to other sub -items will be transferred to other sub -items. Unreasonable profit returns. During the signing of the contract, the construction unit and design unit discovered the problem and negotiated with the construction unit. It was intended to optimize the design of the error item of the bidding list project. Elementary errors lead to the determination and investigation of the risk of investment management and control.

Analysis of the cause

According to analysis, it was found that the four large and medium -sized water conservancy projects were used to use the Sichuan Water Conservancy Project Standard Construction Bidding documents when bidding. The corresponding evaluation measures did not require bid evaluation experts to review the imbalance of bidders. Therefore In unbalanced quotations during the bidding stage, in the construction stage, the risk of changing the relevant sub -item transfers through engineering changes to obtain unreasonable profits.

At present, in the "Sichuan Provincial Water Conservancy Project Construction Bidding Documents (2020 Edition)" adopted by the construction bidding project of large and medium -sized water conservancy projects in Sichuan Province in Sichuan Province, although the evaluation measures are required to conduct the unit price of the bidder's offer quotation, etc. According to analysis, a clear letter (excluding a single item without quotation) shall be issued to it shall be issued a clear letter, requiring the bidder to make a written explanation and provide relevant certification materials. However In the process of evaluation of the bid evaluation committee, there is no standard standard for "obvious low single items", which is not conducive to accurately analyzing and evaluating bid evaluation experts. It is not operable.

Third, countermeasures and suggestions

(1) Standards for quantitative imbalance quotation. Establish a list of bidding for bidding for the project volume list of Sichuan Province's water conservancy project construction projects, refine the rules for review of the standard documents of the bidding standards of water conservancy projects, standardize the evaluation of unbalanced quotations, and safeguard the legitimate rights and interests of bidders. Provide the bidding and control price to the bid evaluation committee (including the unit price of each child). When the amount of the bidder's unbalanced quotation project exceeds the certain amplitude of the bidding control price, the bid evaluation committee shall reject the bidding; Do a good job of risk prevention prompts. It is clear that the main materials (engineering equipment) that need to be reviewed, and the unit price of the same main material (engineering equipment) is inconsistent, highly high or obviously unreasonable, the bid evaluation committee shall ask the bidder to review according to the bidder's explanation reasons.

(2) Improve the treatment of unit price omissions. The bidding documents should scientifically clarify the principle of unit price omissions. When the amount of the bidder's unit price omissions exceeds a certain extent of the total bidding price (after the correction), in order to avoid malicious changes in the implementation process, the bid evaluation committee shall veto the bidding; Within the scope, it can be regarded as the bidder promised to the bidder for free, or it is regarded as the cost of other related sub -prices (prices) of the other related sub -purpose of the project quantity list. , But the sub -project project shall not be priced separately. (3) Improve the accuracy of the quantity list. The clear construction process of engineering quantities should be combined with the actual situation of the project site. Especially in recent years, the disputed stone square hole in the construction of water conservancy projects has been used to avoid malicious bidders lower than the cost quotation, and the rest of the sub -items that do not apply the construction process. Ultra -high quotations, more unreasonable construction profits are obtained through project changes during the construction stage. The bidder should strengthen the review of the project quantity list to prevent major errors. For unbalanced quotes with large deviations, it should be discovered and properly resolved in time during the construction process. Investment caused by malicious unbalanced quotation.
