EXTREME DAM REPAIR

Sensing and measurement technologies are playing a significant role in the current $594 million rehabilitation of the Wolf Creek Dam in south-central Kentucky. Using sophisticated monitoring and control systems, crews are drilling 1.3 m (50 in) diameter piles as deep as 84 m (275 ft) as they construct a 1,201 m (3,940 ft) long secant wall concrete barrier along the spine of the 60-year-old earthen embankment.

The project began in 2008 and the owners expect it to be completed in 2014. Despite its unprecedented parameters, no production rework has been required to date..
