Kentucky Lock - Grand Rivers, Kentucky

Black & Veatch has provided studies and designs for multiple features of the new lock at the Kentucky Dam. The new lock is 110 feet by 1,200 feet and is being constructed on hard limestone adjacent to the existing 100-foot by 600-foot chamber.

The lock is being designed according to a combination of criteria from the U.S. Army Corps of Engineers and the Tennessee Valley Authority. Tasks performed include:

• Phase I Design Documentation Report for upstream end of lock structure including a design loading criteria report, and soil structure interaction analysis (for earthquake loads).
  
• Preliminary and final design and construction phase assistance of the upstream cofferdam.
  
• Blasting study to assess rock excavation and blasting effects on adjacent structures including lock, power plant, substation and switchyard, transmission towers and other miscellaneous structures.
• Secondary cutoff wall evaluation for a second line of protection against loss of lake pool.
