Who built the Laos dam that collapsed?
Construction of the earth-filled Saddle Dam D near Paksong, part of the $1.2bn (£915m) hydroelectric project by Xe-Pian Xe-Namnoy Power Company (PNPC), was begun in 2013. The hydroelectric project was a build-operate-transfer project.
What was the cause of the dam collapse in Laos?
Poor construction methods, with soil used in place of concrete, caused a fatal hydropower dam collapse last year in Laos, a panel of water experts has concluded, prompting a rejection of its findings by the South Korean firm that built the project.
How many people died from dams?
Millions of people lost their homes. The death toll estimates for these failures varied widely. Approximately 26,000 deaths occurred from drowning in the immediate aftermath of the dam collapses. There were as many as 230,000 deaths if those who died of consequent health epidemics and famine are included.
What happen if dam collapse?

Is Hoover Dam still curing?
Is Hoover Dam Concrete Still Curing? In short, yes – the concrete is still curing, harder and harder every year even in 2017 some 82 years after the construction of Hoover Dam was completed in 1935.
Has anyone fallen off Hoover Dam?
An unnamed source stated that since 1936 when the dam was completed and open for tours, approximately 100 people had perished by suicide. Compare the number of suicides at the dam to other sites such as the Golden Gate Bridge, where since its 1937 opening, more than 1600 documented deaths have been recorded.
