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

763 views

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.

Wood has to be fairly wet before it starts growing mold, like 30-40% moisture content. Normal construction lumber comes in around 15-20%, you’d have to leave it in a pool to soak up enough to start decaying.

Eventually they’ll get the “shell” up, the roof and wall sheathing with building paper. Then there’ll be a period of time where HVAC, rough plumbing and rough electric work is being done. During this time any residual moisture in or on the framing has a chance to dry before it gets sealed in by drywall.
