venting exhaust fan through basement wall

We're adding a new bathroom in the basement of our 1920's house. The exhaust van duct needs to be vented to the exterior. The basement walls are very solid, poured concrete. The electrician wants to cut a hole in the wood 2x10 rim joist above the concrete wall. Because this 2x10 rim runs perpendicular to the joists, I don't think it would be a problem structurally, but cutting a 3" diam. hole in the side of the house makes me nervious. Any thoughts?

Drilling a hole in the side of the house makes most people nervous. With some good silicone or urethane sealant you will be fine.

This is reasonable, should be no problem structurally. I might need new glasses, 'cuz I can't see it from here.

As mentioned before doing it correctly is no problem. In fact, if you walk around your house you'll notice a few vents, pipes, wires, etc going in n out.

The key is to seal around the vent. Use elastic soft putty, sold in a lb package at HD.
