This video provides an overview of a construction project to build a new dam in the Swiss Alps to replace an aging dam. The original dam, built in the 1930s, developed structural issues and cannot be repaired. The new dam is a double curvature design and is being constructed alongside the old dam.
The project faces unique challenges due to its remote location, high altitude, and harsh winters. Work must stop during the snowy months, and getting materials and equipment to the site is difficult. The construction process involves controlled explosives, massive amounts of concrete, and the creation of a tunnel for water discharge.
Despite the challenges, the project aims to ensure the region's water supply and hydroelectric power generation while preserving the historic significance of the old dam. The cost of the new dam is around $140 million, and completion is expected by 2025.
Here are the key facts extracted from the text:
1. A massive dam is being constructed in the Swiss Alps.
2. The construction site is at an elevation of 2,000 meters above sea level and is only accessible for a few months each year due to winter conditions.
3. The original dam on the site is almost a century old, has a crack, and is beyond repair.
4. The decision to build a new dam in front of the old one was made due to the risk associated with repairing the original dam.
5. Switzerland experiences frequent earthquakes, and there are concerns about the old dam's stability in the event of an earthquake.
6. Sediment has built up behind the old dam, which could impact water release from the reservoir.
7. Building the new dam involves constructing a double curvature dam and excavating a tunnel through the mountain.
8. A dedicated on-site concrete plant uses granite from a nearby power plant construction.
9. Construction work is challenging due to extreme weather conditions, including heavy snowfall in winter.
10. The construction site is remote and difficult to access, with twisting mountain passes.
11. Tower cranes were brought to the site in sections via the grimsel pass due to limited space.
