The project has many... storms
Mr. Nguyen Cong Thanh - Deputy Director of the Provincial Construction Investment Project Management Board (PPMB) said that the Vo Chi Cong High School project was approved by the Provincial People's Committee in Decision No. 2810, dated September 5, 2019, with the Provincial Construction Investment Project Management Board as the investor, and the Central and Central Highlands Institute of Water Resources as the project consultant.
Initially, the project invested in the construction of the following items: administrative block, laboratory - library block, public house, multi-purpose house, leveling, retaining wall, fence, internal road and auxiliary items. The project has been completed and put into use.
However, at the end of 2020, due to prolonged heavy rains, the hill behind the school collapsed, making it unsafe for the school and the people living at the foot of the hill. Teachers and students of the school had to move to borrow another facility to teach.
After many inspections by provincial leaders and survey results by competent authorities, the Provincial People's Committee approved the adjustment of the Vo Chi Cong High School project - the additional embankment to prevent landslides in Decision No. 1298, dated June 26, 2023.
Accordingly, additional investment will be made in the following items: positive slope roof; negative slope roof; drainage ditch; secondary gate fence; landslide monitoring and early warning system; training and drills on landslide prevention; compensation, support, and site clearance. The total investment after adjustment and addition is more than 58.8 billion VND.
By December 2023, the Provincial Construction Investment Project Management Board had completed the approval of the design and estimate documents. However, at this time, the Bidding Law had just been issued but there was no guiding decree, so it was not possible to select a contractor. The project continued to be delayed.
On March 21 and 22, 2024, a working delegation of the Provincial Party Committee, People's Council, and Provincial People's Committee, led by Provincial Party Secretary Luong Nguyen Minh Triet, visited Vo Chi Cong High School and worked with Tay Giang District Party Committee.
On March 29, 2024, the Provincial Party Committee issued Notice No. 736 and on April 1, 2024, the Provincial People's Committee issued Official Dispatch No. 2202, requesting relevant units to review, evaluate and have optimal solutions for anti-erosion embankments, and report to competent authorities for consideration and decision.
Calculate the plan, make the investment soon
Recently, at the meeting of the Provincial People's Committee to give comments on the plan and design solutions to implement the project of adding embankments to prevent landslides, Mr. Nguyen Ngoc Vinh - head of design of the Central and Central Highlands Institute of Water Resources Science (design consultant) gave an overview of the design solution and calculation of the stability of the embankment to prevent landslides at Vo Chi Cong High School.
According to the approved design documents, the calculation of the embankment takes into account the most unfavorable situations (heavy rain 400mm/24 hours 3 - 4 days before, saturated soil, considering level 7 earthquake).
At the same time, the type of construction item included in the calculation is a level I disaster prevention project to apply the highest safety level calculation coefficient.
The design consultant also reported on the additional plan to level the hill from the top elevation of +1,215m to +1,175m, creating a land fund of about 3 hectares, with a leveling volume of about 700 thousand cubic meters; the total implementation cost is about 120 billion VND, including the cost of leveling, construction of the embankment system, technical infrastructure, and compensation for site clearance.
In addition, the unit proposed to reinforce an additional embankment section of about 70m long running along the traffic route, connecting with the embankment according to the approved design documents to ensure safety for the residential area at the foot of the hill, with an estimated cost of about 6 billion VND.
However, representatives of the Department of Construction and the Department of Planning and Investment both said that the proposed plan to level the hill and the approved design plan to prevent landslides need to be compared to find the most optimal solution.
If the hill leveling plan is implemented, it is still necessary to invest in anti-erosion embankments, which cannot reduce the scale according to the approved design, and at the same time does not increase the safety level of the area that needs protection.
The land fund created after leveling and lowering the elevation can be used for about 3 hectares of land, with a construction density of about 40% according to regulations, only ensuring arrangement for 30 - 40 households.
The total cost of leveling the hill according to the design consultant's report is 120 billion VND, so the investment rate of about 40 billion VND/ha and 3 - 4 billion VND/household is too large. Therefore, representatives of these two departments proposed to continue implementing the approved project.
The provincial construction investment project management board also believes that it is necessary to separate the hill leveling project into a project for later consideration.
In the immediate future, Vice Chairman of the Provincial People's Committee Tran Anh Tuan said that the project to add embankments to prevent landslides is very urgent and has special significance in ensuring the safety of lives and teaching work.
Therefore, the project management board, consulting unit and related sectors must seriously and urgently assess the impact and long-term effectiveness of the embankment project.
The Department of Construction presides over, based on the advantages and disadvantages of the hill leveling plan, and reports to the Provincial People's Committee. The Provincial Construction Investment Project Management Board quickly deploys the next tasks to soon implement the investment and put the project into use.
