North Carolina Hydro Dam

  • Location: Stanley, NC
  • Owner: N/A
  • General Contractor: Brayman Construction Corporation
  • Estimated Value: $500K
  • Completion Date: January 2018

Ten vertical drain holes were core drilled from the crest of the dam 120 feet deep into the dam.  Intersecting holes were drilled from within the gallery of the dam to connect to the vertical holes in order to create new drains to help relieve uplift pressure in the horizontal monolith joints of the dam. 3D survey modeling as well as state of the art locating equipment was used to ensure the two 3-inch diameter holes intersected on a precise location within the mass concrete of the dam. Brayman successfully hit a needle in a haystack 10 out of 10 times.
