Mano Manoharan

I have more than 35 years professional experience in planning, design, construction and maintenance of roads, & bridges, contract administration, asset management and program management. Furthermore, I have proven my ability to manage large scale construction & maintenance and technical projects and programs. In addition to that, I have extensive technical development and operational experience with HDM-4,dTIMS and SCENARIO pavement management systems.
