Mosul Dam Rehabilitation Project wins DFI Outstanding Project Award

The winner of the DFI’s 2022 Outstanding Project Award is the Mosul Dam Rehabilitation Project, in Iraq, submitted by Trevi, S.p.A., service foundation division of Trevi Group.

The award is being presented at DFI’s 47th Annual Conference on Deep Foundations, October 4-7 in National Harbor, Maryland.

This project not only confirmed Trevi’s worldwide leadership in the rehabilitation and retrofitting of dams, but also once again displayed the Company’s ability to operate in the harshest, most challenging conditions with dedication, humanity, accountability and expertise.

The Mosul Dam on the Tigris River dates to the 1980s and is the largest in Iraq at 113 m (371 ft) tall and 3.65 km (2.3 mi) long. Even during the construction phase, engineers were aware of the foundation’s weak rock, and contractors encountered cavities during excavation. Due to political and schedule pressures, the work continued. Despite extensive grouting efforts, water seepages started immediately after commissioning the dam.

In March 2016 Trevi took over the contract to perform maintenance grouting, along with training the owner’s personnel and rehabilitating the bottom outlet tunnels through electromechanical work and diving operations.

From 2016 to 2019, Trevi completed about 403,000 linear m (1,322,178 lft) of grouted boreholes, injecting about 41,000 m3 (53,626 cu yd) of grout — equivalent to 26,700 tons of solids — into the ground. Trevi also created courses on modern equipment and techniques as part of its remit to engage and train the owner’s personnel.

Trevi carried out work at the dam, a mere 13 km (8 mi) away from the armed conflict against ISIS. Fortunately, the presence of the Coalition Forces, together with the Italian Army, guaranteed the required security of the project area. Notwithstanding the strict security procedures, the works proceeded expeditiously with no delays.

The workforce numbered more than 700 and the project logged 8 million man-hours worked without accidents.

Special recognition awards are also being presented to three other projects: City Ridge Roadside Development in Washington, D.C., by Berkel & Company; Eglinton Crosstown LRT – Cedarvale Station in Toronto, by Isherwood Geostructural Engineers; and Harold Structures B/C Approach in Queens, New York, by Underpinning & Foundations Skanska.
