Client's Challenges

Khai Ding Bridge is part of THE XL10 construction package of the Cam Lo - La Son section, which passes through Thua Thien Hue and Quang Tri Province. The package consists of the construction of a reinforced soil structure, featuring a maximum height of 10m. As the bridge is located in the vicinity of a residential area, small machineries and equipments were preferred to minimise traffic disruptions.
