New Shop Build - With Questions

[ebridges]

Hello everyone, I have been on here for a while but this is my first thread. I'm just starting to build my first shop and I have a few technical questions (I attached a couple pictures from the plans). I have plans engineered and the footings dug out and ready to be poured next week. I have a concrete guy that will be doing most of that work with my help however I'm acting as the general on this project so I need to make sure it is done right and it will work for the next step(s) of the project. I have some knowledge of building construction but this is my first project of this scale. I'm getting very familiar with residential building codes but it is difficult to find some answers and I don't want to have to ask my inspector what might seem like silly questions. First, I'm pulling power from the house (100amps) and my electrician asked for 1 1/4" conduit to the building. I could run it up the outside wall but since there is no meter on the outside it would be cleaner/neater to run it through the footer and/or stem wall up into the stud bay that way it's completely hidden. Can I do that? Will they have a problem with conduit coming from outside the side of the stem wall and then exit the top of the stem wall?

Also, my engineer specified Simpson HDU hold downs for the shear walls. I am a little unsure of how to know where to place the anchor bolts. These hold downs attach to the corner studs and then have a 5/8" or 1" bolt embedded into the stem wall. I don't know how to locate them exactly where they need to be for the framers. I might see if I can get my framing guy to come out and tell me where he wants them? I'm not sure if the corners will be 3 stud corners or not. I guess I could assume they're 3 stud corners and measure back 7.5" from the edge of the stem wall (it calls for 3x6 studs on shear walls). Does this sound reasonable?

First, for your electrical.
I would go with a 2 inch "sweep 90" for the feed from horizontal to vertical.
The extra room and easier angle will get you favors later.
Second, you can route it through the concrete so it comes up inside your wall.
Just be sure your concrete guy knows what you want.

For the hold down bolts:
Do you have drawings?
If not, a meeting between your concrete guy and your carpenter may be a good idea.

While you are running this power conduit consider another one for low voltage wiring: Cat 5 cables, smoke alarm interlock wiring, security system wiring, etc.

You can bury whatever you want in the concrete, it just needs a reliable location and enough care to fixture it so when the heavy mud starts flowing it doesn't just push it out of the way.

The anchor bolts need to be tied to a framing detail imo. You (or someone!) needs to merge the concrete, framing, and HDU "layers" of the drawing to create one that is accessible to both the trades.

Along those lines, there can be some issues with burying conduit in a wall. For example, an "LB" is typically used for a tight turn, but that's impossible to fish thru if its already buried in the wall. That's why a lot of times an LB comes up the outside and penetrates the entire wall to land in the back of the circuit panel. In any case, its a good idea to have the same discussion with your electrician.

The devil is in the details in any build, and hand drawn sketches, even if not to scale, convey the ideas a lot faster than spoken words and the various trades can mark up your drawing to show what they would like to change.

I pulled my wire through the conduit as I went 100' of that heavy wire will be a bear. So only 10' @ a time will be a lot easier. Same with the sweeping 90's and that LB. Harry
