More library construction fun!
Some very interesting work going on here lately at Drake Library; we had a technician in to use ground penetrating radar to "see" through the concrete floor. By doing that he could identify where the "rebar" is, the steel reinforcing rods in the concrete, and thus mark where there is only concrete, through which our campus workers could safely drill. The holes now being drilled will allow much neater and more expansive addition of electric and internet lines that running them above the floor. At left is the sort of image the radar tech saw when looking through the concrete - it reveals rebar about 3" below the surface (imagine a line drawn along the peaks of the dark line running left to right in the upper 1/3 of the image.)
