Passing conduit through pole building and home foundation

[rcsracing]

I'm in the middle of construction for a 40x64 pole building (not me, but I'm the GC).

While the plumbers are connecting water/septic, they'll have a trench from garage to my house, where most of the utilities enter. As an IT guy, I'm planning on real connectivity out there, and I've settled on 2xCat6a direct bury runs. I'm planning on sharing the trench with the utilities, and entering both the home and garage.

Direct bury for the main run, and then the vertical along the house/garage would be in Sch80 with what I think is a service elbow going in. Then what?

Looks like 3/4" schedule 80 is big enough for this. OD of the pipe is 1.05" (so 1 1/16 drill). On the house, that's a poured foundation for my basement. Hammer drill @ 1 1/16, then some type of sealant around both the outside and inside of the conduit? What about entering the side of the pole barn? 6x6 w/ 2x4 purlins every 2'). No interior finish yet, but there will be insulation and wall finish. Again, outside the pipe and then inside the pipe (Probably at both ends?).

Basically I'm thinking a 90* setup that goes down the 18-24" to pick up the cables from the trench, then enter each building and then off to the nearby patch panel (cables will be grounded only on one building to prevent a ground loop).

Thanks!!!

1-1/8 is the standard bore size for 3/4"c. 1-3/8 would even be better to help keep ****** square through the wall and have room for caulk or grout.

What you do inside at both ends depends on damage potential. Continue it further in conduit or staple it to match the contour of the surface.

Thanks - especially on sizing. The vertical, will go down to the trench and just transition to open. Maybe a corner/radius piece. Spray foam in that to transition from direct bury to conduit. Other end will be in my basement - same plan - spray foam inside.

Cat 6 between buildings is susceptible to lightning. Be sure to put surge protectors on both ends, or better yet use fiber with media converters on each end.

I would go to at least 1". Much more flexibility if you want to install preterminated fiber or whatever. On the pole barn end just come up in the outer wall - eliminates siding penetration.

This. Lightning won't blow up the CAT6 itself, but it'll induce enough voltage that you'll fry at the ends and terminations where it joins equipment. The strike does not have to be direct, it just needs to be near by, just a few neighbors over.

I have not done shielded/grounded, that may do a little better in this situation, but my choice would be fiber too.
