The U.S. Army Corps of Engineers seeks information on firms capable of carrying out a 24-hour-a-day grouting program at Iraq's 750-MW Mosul Dam on the Tigris River. Responses are due May 1.
Mosul Dam was seized by the Islamic State of Iraq and Syria (ISIS or ISIL) in 2014. Control of the hydro project was recovered by a coordinated operation of U.S., Kurdish and Iraqi forces.
The largest dam in Iraq, Mosul was completed in 1984 on a soluble foundation of gypsum, anhydrite, and karstic limestone. To save construction time, foundation grouting was not completed ahead of time. It began seeping immediately upon filling of the reservoir in 1985 in Ninewah Province. Iraq has carried out a major grouting program continuously since that time.
The Corps concluded in 2006 that "in terms of internal erosion potential of the foundation, Mosul Dam is the most dangerous dam in the world... If a small problem at Mosul Dam occurs, failure is likely." A University of Arkansas civil engineering professor used satellite-based radar images to determine the structure is subsiding at a rate of 8 millimeters per year.
In a sources sought notice, the Corps' Middle East District seeks information on firms capable of carrying out a 24-hours-a-day, seven-days-a-week grouting program in a concrete-reinforced grouting gallery at the base of the central clay core of Mosul Dam. It plans to use responses as market research to garner interest from industry.
It anticipates issuing a one-year contract with four one-year option periods with an estimated cost of US$250 million to US$500 million.
A sources sought notice may be obtained from the Federal Business Opportunities Internet site, www.fbo.gov, by entering Solicitation No. W912ER15R0018 in the "Keyword/Solicitation #" box.
Responses are due by 4 p.m., U.S. Eastern time, May 1 by e-mail to the addresses below, labeled "Market Research for W912ER-15-R-0018 Mosul Dam."
