Setting Anchor bolts

I'm a mason that usually does high end stone and brick work for the slightly more discriminating customer.
By word of mouth I was asked on to a crazy modern home project. There are lots of steel columns and beams in the house (and lots of crazy angles) and he wanted me to do the anchor installation. He has seen my work and knows I'm very good with layout.
Anchor bolts go in, steel gets set. The next day the steel guy calls me and says since he has been in business that was the 1st job he didn't have to burn any extra holes in the base plates. :laughing: He wants me to do the next house he has lined up. Question is, anyone using a Hilti DD 120? I'm thinking of buying one.
And as far as epoxy I'm using Ultra Bond 1 from Adhesives Technology, seems to work great, engineer has OKed it also.
I'm also going to contact some other local steel companies and let them know I'm available.
What is the usual scenario with residential anchoring? Do you steel guys do it? Or sub it out? Or does the GC take care of it?

Joasis would be the guy to
talk to on that one.
My anchor bolt days were institutional
and commercial...all stuck wet.
(As far as anyone knows) :whistling
Wet is the way to go, but usually around here the crete already in before they finish the steel plan. Don't ask me why.:rolleyes:
In my experience on smaller jobs like a single fam. home it's about 33.3/33.3/33.3 split between the GC getting it done by whoever he can find, or the concrete guys setting them wet, or the erector setting them. Whenever I get stuck setting anchors I'll usually stand a column set the anchors and move on till the columns are set. On larger projects set it wet is the only way to go, and code in most cases.

As far as Hilti drills go you can't go wrong. But I have to ask what size holes are you drilling? That's way more drill than you need for 99 out of 100 anchor jobs. A quality sds or spline drive hammer drill, even a Hilti, will be tons cheaper and way easier to run than that core drill set up.
That drill is very good but not necessary only if you have lots of rebar or trying to drill out anchor bolts set wrong. I would go with h a SDS max hammer drill. As far as epoxy I always used Hilti 2 part system in the foil tubes. In my case the mason or concrete guy always set his own bolts I have poured 100,000+ Cy of concrete and 10,000+ anchor bolts And always were 99% pre hung and set with fresh concrete the only time we drilled and epoxy was an ocasioml mistake or if there where changes or missed.
Diamond Cored Holes

Only a few epoxys will work with a diamond cored hole because of how smooth they are. RE 500 is one of them. There are also SDS drill bits made for rebar
