All of the vertical steel beams that support the stadium were to be encased in concrete as part of the renovation project. This required enlarging the original footings that all of the beams sat on. To do this, they had to excavate down around the original footings that were generally about 4’ to 5’ square, then drill two rows of four holes on each side of the footings. After installing the rebar with epoxy, they would pour the concrete to widen each footing. This involved the drilling of over 7,600 holes that were to be 7/8” diameter and 8” deep. Drilling by hand would be extremely time consuming and labor intensive. E-Z Drill suggested using the Model 85B with a slight modification on the legs to be able to reach both rows of holes on each footing.
The E-Z Drill Model 85B was a huge success. It drilled the 7/8” x 8” holes in approximately 22 seconds. Flintco officials even told E-Z Drill that they determined that the Model 85B could drill four holes in the time it took to drill one hole by hand!
All of the drilling was finished within about five weeks, and the use of the E-Z Drill Model 85B was a big factor in Flintco being able to stay on schedule.
