core drilling a cement block wall - $275

This is a small core drilling job we did in Morrisville, NC, which is a small suburb of Raleigh, NC. The 5 inch core drill holes in the block wall were for new gas lines at the newly constructed Duke medical center on Arlington Dr. Most cement block walls are poured with concrete and rebar every other block or 16 inches, sometimes every 24 inches depending the load weigh of the wall itself. The height of this particular hole on the wall made it a great project to teach some core drilling skills to one of our young core drill operators that is eager to learn the trade.
