U.S. extends query of firms to increase height of Dahla Dam, Afghanistan

The U.S. Army Corps of Engineers has extended its request for information on firms capable of increasing the height of Afghanistan’s Dahla Dam, an irrigation project with three small hydroelectric generators. Responses now are due February 29.

The Corps previously called for responses by February 10. It issued a similar request in 2011, as well as an inquiry about firms to perform major rehabilitation work at Afghanistan’s 33-MW Kajaki Dam.

Dahla Dam is on the Arghandab River about 34 kilometers northeast of Kandahar. The project supplies irrigation water, a small amount of hydropower, and is being considered to supply municipal water. The reservoir has lost about 30 percent of its storage capacity due to sedimentation.

In an initiative by the government of Canada, a joint venture of Canadian engineering and construction group SNC-Lavalin and Canadian consulting firm Hydrosult managed rehabilitation of Dahla Dam to restore supply of irrigation water to the area.

The Corps’ Transatlantic South District now seeks to establish a list of qualified companies capable of increasing the height of Dahla Dam at least 5 meters with an option for an additional 3 meters. The Corps seeks firms able to restore storage capacity by raising the earth and rockfill dam, saddle dikes, and spillways, and by modifying structural, hydraulic, and electro-mechanical features. The work is valued at between US$100 million and US$250 million

A sources sought notice may be obtained from the Federal Business Opportunities Internet site, www.fbo.gov, by entering Solicitation No. W5J9LE12SS0003 in the “Keyword/Solicitation #” box.
