Our proposal has replaced design proposal of other 9 biggest consultants in the transportation consultant field. The design later has proved with high drainage capacity and flood mitigation affect with much low cost compare with other section (from Dongha to Quangngai). This project was recognize and accepted in the project monitoring and evaluation conference in Danang in 2003, four years after completion of our project.
