Preparing for new garage

[joshua5438]

Hello, I am getting ready to build a 30x50x12 metal garage. Below is my list of questions -

1 - I have decided to pre plumb for a half bath but it may be years down the road before I get to installing it. I was wondering if I can run 2" PVC from outside the garage and then stub up inside through the slab to eventually run PEX? This way I am not dealing with PEX before the build and I can always fish it through later. It would only be about a 5 foot run. Any additional tips on doing stub outs would be great also.

2 - I am planning to have a future two post lift capable of lifting 9,000lbs (Crew Cab F250 Diesel will be the heaviest it will see). I have looked up many specs for two post lifts and have decided to go with one bay of the garage at 5" thick and the remainder at 4" thick. I am thinking a full bay (15 wide by 30 long) as I am not totally sure about the placement from the roll up door. I have read that 12 feet from door to center of lift post is ideal? Any suggestions or opinions would be great.

3 - To get the electrical inside I plan to use 2" conduit and sub up just inside the metal frame probably in a corner of the garage. I will be feeding off of my two car garage that has it's own 200amp feed. I have not decided if I want to do a sub panel of 100 or 150 at this point.

I am sure I will have more questions and look forward all I can learn from you all. Thanks in advance for all of your help.

Here is a quick layout.

I did some additional research and found that I should keep control joints less than 12' for 4" thick concrete and 15' for 5" thick. Here is the new control joint layout. I have also moved the lift back 3 feet to get it away from the control joint and to also allow more room behind the truck when it's lifted. I may need to move it more if I decide to get an asymmetrical lift?

It's the drain that you really need to worry about. Stub that out for sure.
I like putting 2" electrical sweeps in every corner of the shop (to the outside)
I also like putting in 1 - 1-1/4 electrical across the slab (under) and bring it up both sides.

Yes, you can easily run PEX in PVC. You don't need 2". I'd think for a structure this size, you just need to get a 3/4" PEX line in... Confirm the size that will fit through, but I believe 1-1/4 electrical is where you want to be. The sweeps are necessary, you can't easily do it with regular pvc fittings. And you may have to guide it through with a fish line and a connector on the end of the pex.

Thanks for the info. The sweep instead of PVC makes since. It would be a lot easier to feed the PEX in. I was figuring it would be frowned upon to use electrical conduit instead of PVC.
