Song Da Water Pipe Department’ version 2 in the Central Highlands cannot be used due to wrong design

Many mistakes in project design

Information from the Department of Construction of Dak Lak province said that there were inspection results for the subproject Water supply for coffee trees in Tien Cuong village, and at the same time, the inspection team chaired by the Department of Construction identified the cause of the problem. The reason why this project, although invested more than 70 billion VND, could not be put into use.

The subproject Water supply for coffee trees in Tien Cuong village had many mistakes from the beginning

According to the results of the inspection team, the main reason why this project cannot be put into use is because the design unit is Cenco Investment and Construction Joint Stock Company (headquartered in Trang hamlet, Thanh Liet commune, district). Thanh Tri, Hanoi) made a mistake in calculation and design.

Specifically, this unit has applied the wrong standard, leading to the calculation of the selection of pipes under low pressure, which is not guaranteed compared to water pressure. During the design process, this company also did not calculate the force of water impact, did not arrange a pressure reducing device in the event of water impact, did not design anchor abutments at diversion positions, did not calculate internal forces in the road. tube…

Song Da water pipeline version 2 in the Central Highlands experienced 13 pipe breaks in 1 year

The inspection team determined that the cause of the pipe rupture and water leakage at the pipeline joint during the pressure test and test operation was due to calculations and design shortcomings plus inadequate construction implementation. correct and missing some items compared to the approved design documents.

Check the cause of the water pipe burst 13 times a year

Accordingly, Cenco Company has applied the wrong standard, leading to the calculation and selection of low-pressure pipeline, which is not guaranteed compared to water pressure. During the design process, this company also did not calculate the force of water impact, did not arrange a pressure reducing device in the event of water impact, did not design anchor abutments at diversion positions, did not calculate internal forces in the road. tube…

Proposals to handle related organizations and individuals

With a series of errors at the scandalous project, the inspection team proposed to the People’s Committee of Dak Lak province to assign the Department of Agriculture and Rural Development to request the design consultancy unit to coordinate with related units to conduct inspection, survey and calculation. rebuild the entire pipeline according to the actual status quo to have additional design plans, urgently overcome, and soon put the work into use.

The project is now completed but cannot be used

At the same time, the Department of Agriculture and Rural Development, based on the contract with the contractors, continues to review and summarize other violations, propose the Provincial People’s Committee to handle the responsibility for the individuals and units involved in the investment management work. investment in the construction of the above sub-project.

For the appraisal unit (Irrigation Sub-Department, under the Department of Agriculture and Rural Development) during the appraisal process, it does not detect shortcomings in the design documents. It is recommended to review and determine the responsibility of the organization and individuals. relevant persons under the authority.

As Infonet has reflected, despite being invested with a large amount of money (nearly 73 billion VND) from the loan capital of the Asian Bank (ADB) and the counterpart capital of the Government of Vietnam, the project of water supply for coffee trees still in Cu M’Gar district (Dak Lak) cannot operate because of too many errors.

Specifically, even though it has been over a year and the construction money has been paid to almost all of the contractors, the main pipeline broke 13 times during the pressure test. Especially this problem is almost impossible to fix; If it can be fixed, the cost will “team” up to tens of billions of dong.

Soon after, the Inspector of the Ministry of Agriculture and Rural Development quickly stepped in. In May 2021, this agency issued a conclusion confirming that this project had many mistakes, notably the capacity of the design unit.

Specifically, the Inspectorate of the Ministry of Agriculture and Rural Development determined that the consulting contractor of CENCO Investment and Construction Joint Stock Company (Construction and Investment Joint Stock Company) did not meet the prescribed capacity conditions. The bidding documents stipulate that the experience of the contractor who has performed similar bidding packages within the past 7 years (from the time of bid closing) is not in accordance with the regulations, this contractor also does not have any contract. In the last 5 years, there is a component on institutional model building.

In addition to pointing out the serious shortcomings of the survey and design unit CENCO, the Inspector of the Ministry of Agriculture and Rural Development also pointed out a series of other errors surrounding this work such as: the formulation of the project. , appraise and approve investment projects when the basic design explanation is incomplete according to the provisions of the Construction Law.

Sub-project Water supply for coffee irrigation in Tien Cuong village (Quang Tien commune, Cu M’gar district, Dak Lak) invested by Dak Lak Department of Agriculture and Rural Development, with a total investment of more than 72 billion VND, is expected when the project is completed. The completed process will serve water for about 400 hectares of coffee and pepper in this locality.
