Vietnamese infrastructure development company Cavico announced this week that it had broken through the sub tunnel at the A Luoi Hydropower project in Central Vietnam. Cavico excavated approximately 1950m of tunnel from the sub-tunnel No. 1 to sub-tunnel No. 2.
The A Luoi Hydropower plant, owned by Central Hydropower Joint Stock, is built on the A Sap River in the Thua Thien Hue province. The 170 mW-capacity hydropower plant is expected to generate approximately 686 million kWh annually for the region.
In July 2007 Cavico was awarded a contract to excavate a 12km long, 5m wide headrace tunnel at the project. In addition to the headrace tunnel, the company was also contracted to excavate four sub-tunnels, a surge tank, a vertical shaft, and a service access road. The total expected revenue value from the A Luoi project is USD 53 million.
Cavico vice president Hai Thanh Tran said, “We are pleased with our progress at the A Luoi Hydropower project. The sophistication of this tunnel requires the highest and most efficient level of technical knowledge, which Cavico’s talented team possesses.” Tran added, “We continue to focus our efforts on completing this project in the safest and most timely manner.”
