Greater Mekong Subregion Flood and Drought Risk Management and Mitigation Project 

Project costing at design stage should realiably estimate the costs of all civil and other engineering costs and provide allowance for foreign currency fluctuations. The actual cost of one irrigation scheme turned out some $10 million greater than estimated at approval. This resulted in significant revision to the subproject design. The revision also incorporated the appreciation in special drawing rights against the US dollar and the domestic and international inflation that pushed down the real value of project resources.
