Problems addressed by the Project

The implementation of the ‘Doi Moi’ (Renovation) policy has yielded drastic socio-economic and cultural development in Hanoi, Capital of Vietnam. Subsequently, rapid urbanization and population growth has increased demand for transportation in the city resulting in serious traffic congestion. In order to meet this traffic demand, implementation plan for the Hanoi City Ring Road No. 3 (H3RR) was planned since 1998.

H3RR is a ring road functioning as an urban expressway linking the centre of Hanoi with radial road and arterial roads. The South – West section of H3RR (the Red River Bridge Construction Project) has been constructed already funded by JICA and supervised by OC Global. Since the completion of Red River Bridge Construction Project, traffic volume of section Mai Dich – North Linh Dam rapidly increased. This necessitated implementation of this Project.

Section Mai Dich – North Linh Dam is one of most rapidly urbanized areas in Hanoi. Frontage Road was constructed before commencement of this Project. Therefore, the construction work was executed under very limited construction space and there was much public traffic adjacent to the construction site. Therefore, maintaining safety during construction was one of the most important issues in this Project.

Service Provided

OC Global conducted two of the earlier studies for this Project: review of Feasibility Study of this Project by Special Assistance for Project Formation (SAPROF) funded by JICA in 2007. OC Global was subsequently engaged to provide detailed design, pre-qualification and tender assistance. OC Global also provided the construction supervision and defect liability services from May 2010 to 2014.
