This is one of the most challenging sections of the North-South Expressway, specifically the Dien Chau - Bai Vot segment. Therefore, the construction unit is working tirelessly to meet the deadline. Currently, Hoa Hiep Co., Ltd. has mobilized over 200 people, including experienced engineers and skilled workers from various corporations. In addition, they have deployed four modern tunnel boring systems, dozens of concrete spraying machines, wheel loaders, excavators, and are working three shifts continuously. (Photo: Tran Chau) |

Mr. Dao Van Thong, from Do Luong, who drives an excavator for Hoa Hiep Co., Ltd., said: Currently, eight excavators are working all day. Each machine is driven by two people in shifts, each person working one and a half shifts a day, equivalent to 12 hours of continuous work. Construction at a height of 70 meters requires experienced driving skills and safety is paramount. Photo: Hai Viet |
