The project implementation was marked by substantial cost overruns. The detailed design put the cost for civil works about 35% higher than that estimated at appraisal. During implementation, the actual cost rose by about another 15%, including 6.7% for extra works and 8.2% for price escalation in construction materials. Such cost overrun caused three feeder roads packages to be removed from the project scope. In future, similar projects, this experience should be duly taken into account when estimating project costs as well as schedules. Additional costs and time were required due to unexpected amounts of rock needing to be excavated. This would have been difficult to detect in the design stage and could be found only during implementation. Therefore, it is recommended that sufficient contingencies be provided for similar projects.
