Why do the mirrors have to be on the  pillars?  Any way of suspending them out of reach?

How about getting to the essentials? Who pays? Your employer does, right? - hire someone to do it- Use the SS straps- and stay off ladders as much as you can.  I know lots of people who have been hurt falling off ladders. Lots of young healthy guys, gravity does not give a damn.

I'll second (or fifth, I lost track) the motion on industural strength adhesives and bands/straps.  The idea of drilling into structural concrete gives me the willies.

What about one of those explosive bolt systems that use a cartridge to sink an anchor in?

Other than that, I'll agree with glue/adhesive.  They're a lot better than they used to be, used properly.

I hate it when you are home improving, drilling in what is supposed to be a brick wall, until you hit a rattle-tattle bone shaking structure.. damn, should have looked at the plans first.

I wouldn't worry about a limited number of fairly small holes drilled into the pillars from a structural standpoint. I would just think it's an unnecessary PITA, particularly when you don't have the equipment to do it properly.

That is all. *expletive deleted*ck you all, eat *expletive deleted*it, and die in a fire. I have considered writing here a long parting section dedicated to each poster, but I have decided, at length, against it. *expletive deleted*ck you all and Hail Satan.

Until you hit rebar,  3" holes.

Had a buddy catch a piece of rebar with his hole hawg and break his wrist.
