📋 Tender Overview
Although the terrain is high and dangerous, equipment transportation and construction are extremely difficult, the contractors constructing the 220kV Than Uyen - Lao Cai line project are still taking advantage of favorable weather and trying to overcome difficulties to speed up the project progress. The 220kV Than Uyen - Lao Cai line project was started on August 21, 2025, by the National Power Transmission Corporation. (EVNNPT) is the investor, and the Northern Power Project Management Board (NPMB) manages and operates. The project has the scale of building a new two-circuit 220kV line, 73.5 km long, passing through Lai Chau and Lao Cai provinces. Up to now, after 4 months of construction, the project has reached about 50% of the planned volume. When completed, this project will contribute to enhancing power transmission capacity, releasing capacity of regional hydropower plants, adding power to the national power system, reducing power loss and promoting local socio-economic development. The construction of foundation locations is very difficult due to the rugged rocky terrain and narrow construction site - Photo: VGP/Toan Thang Overcoming terrain difficulties, wherever there is a site, the project can be constructed right away. In Duong Quy commune, Lao Cai province, the road to many foundation locations is just narrow vertical slopes along the mountainside. To open temporary roads to serve construction and transport materials and equipment, the construction units have to spend a lot of effort in leveling and paving the road with a very large amount of leveling. Materials and equipment have to be transported through many stages, with some parts where workers have to carry them on foot. Overcoming these difficulties, on the construction site, teams took turns staying put, constructing each item at locations that already had premises, ensuring progress according to the assigned plan. Location No. 55 and No. 57 are the most difficult construction locations. To reach these locations, we have to overcome steep slopes, one side is a rocky mountainside, the other is a deep abyss. Shaking like they were wrestling for a while on the back of the two-wheel drive pickup truck, the group of reporters had to hold tightly to the side of the truck as the vehicle climbed up steep, craggy slopes to reach the construction site. This dangerous scene clearly shows the challenges that construction teams face every day. According to NPMB representatives, after the groundbreaking ceremony on September 5, units simultaneously deployed at the handed over foundation locations. By December 19, 26/61 locations had completed foundation work, 17 locations had erected columns, and the remaining locations were being deployed in parallel. At location 55 of the 220kV Than Uyen - Lao Cai line project, Mr. Luong Gia Tuan, representative of the construction unit of package number 12, said that the unit is constructing sections from locations 32 to 67, the last section of the entire line. At this location, construction conditions are particularly difficult with the total volume of stone to be processed reaching more than 150,000 m3, and the leveling volume exceeding 400,000 m3. Along with that, the construction unit must work in a very narrow, dangerous terrain, near traffic roads, so while constructing, it must have warning measures to prevent soil and rock from landslides onto the road. Location 55 of the 220kV Than Uyen - Lao Cai line project has a very large amount of rock leveling - Photo: VGP/Toan Thang After storms No. 9 and 10, this area became a landslide hot spot, many roads were divided, seriously affecting the transportation of supplies and equipment. To overcome this difficulty, drawing experience from the 500kV circuit 3 line project, the construction unit used specialized vehicles, which construction site people jokingly call yellow ant convoys to transport materials and equipment. It is known that out of a total of 61 foundation locations, only over half have been handed over so far. The investor and the two provincial governments are actively encouraging households to hand over the site as soon as possible. We determine that the site is the key factor. Wherever the site is, we will organize construction immediately. Along with that, take advantage of favorable weather to focus on transporting and gathering materials and equipment for construction without waiting time, Mr. Tuan emphasized. The representative of the construction unit set a goal that all locations where the site is handed over will complete the foundation and erect columns within 50 days, as a premise to be able to pull the rope. Mr. Luong Gia Tuan said, out of 21 foundation positions the unit undertook construction, by December 19, 13 positions had been completed, 10 positions had been erected. The foundation is expected to be completed before December 31, 2025; The erection of poles and pulling of wires will be completed in early 2026. Urgently remove difficulties and focus on speeding up project progress. Mr. Phung Bao Anh, Deputy Director of the Northern Power Project Management Board (NPMB), said that up to now, the project has completed about 50% of the designed volume. The main problems are related to site clearance and conversion of forest use purposes. The arrangement and reorganization of the local government apparatus in recent times has somewhat affected the process of processing documents. At the same time, many officials are carrying out forest conversion work for the first time, so they need more time to research and grasp the regulations. During forest recovery, many households are not qualified to make plans, forcing the Project Management Board to directly support and replace most of the documents, prolonging the processing time.declare. The investor has closely coordinated with local authorities to remove problems and at the same time urged contractors to carry out construction as soon as the site is available. After 4 mont
