Have you ever personally drilled overhead into concrete??? Unless they had a special rig, it would take a full day for 1 guy to drill holes just for one panel!! Maybe even more time than that.

This is the core of this whole tragedy. It took thousands of excess (and unnecessary) hours to drill for and set these bolts, therefore more taxpayer dollars for worker payroll, foremen, contractors, and, of course, outstretched political palms on up the line......

Placing anchor bolts through concrete formwork (prior to placement of concrete) may insure a more foolproof anchor, but it is very difficult, time consuming, and therefore expensive, to do it that way.
