Thickness of grout below baseplate?
(OP)
What determines the required thickness of grout below a column baseplate? Do any standards (AISC, ACI, etc.) specify a range based off column load or baseplate size?

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Epoxy grout is especially vulnerable.
ACI and API have some pretty specific recommendations.
Rotating machinery is particularly critical. I would NEVER leave leveling nuts on the anchor bolts, since tightening the upper hold down nuts later would not clamp the base against the grout

Tmoose, I know you are trying to be helpful and I agree with almost all of your statements - but, I don't think it is appropriate on Eng-Tips to post ACI documents that have been illegally downloaded. I recommend editing your post to change the link to the official ACI site so that we may still have your good post. :)

Usually companies/projects specify/recommends grout thickness or even have its standard drawings specially if they are doing it again and again. It is better to ask your lead/manager if is provided and stick with it. In our firm we have standards so i tend to follow it.

It is obviously written with a viewpoint that 5-Star branded grouts are the only grouts you should use, but almost everything in this handbook is good grouting advice regardless of the type of grout.
If I remember correctly, it basically says that 2" is the recommended grout height for plates up to 3' wide and to increase this grout height 1" for every additional three feet of width.
