i worked on this dam project in 2003. It is 100 % concrete dam. CWHEC was contractor at that time. It supposed to be completed in 2006 but took more time because of security issues. in those days, My boss, Mr. Li was kidnapped but he was recovered soon but the worked was stopped for a year. After that again 3 Chinese were kidnapped, as i remember, out of these 3, 2 were killed and one was recovered. after that CWHEC stopped the work completely.
Later FWO started the project again in 2006 and now today it has been inaugurated.
Want to share one more thing, Gomal zam dam and mirani dam were started in 2002. Gomal zam dam was awarded to Chinese company and Mirani dam was awarded to Pakistani company. Good to inform you that Pakistani company completed its dam project before time in 2007 but Gomal zam dam is late for about 7 years. I worked on both of these projects.
