Eli5: How do construction sites work around rain when wooden studs are exposed?

There’s an apartment complex being built by me and they have most, if not all the framing done. At my job, there’s a huge emphasis on keeping white wood lumber from getting wet because it will ruin the wood. But whenever I drive by this construction site, I see so many studs just exposed. It’s rained a decent amount since they began the project, so I’m wondering if any of the studs are damaged or will become in the future. How will they last the building lifespan after being soaked? 

It is currently pouring as I type this and I can’t help but think what damage is currently being done. Someone put my mind at ease lol.

Moisture in wood isn't an issue. Trapped, constant moisture in wood is an issue.

 Once the roof is on the inside will eventually dry out. It takes a couple weeks to get the plumbing and electrical rough-ins done. The sheathing will dry as well. House wrap and siding is meant to allow air flow.
