Hello.
Our shell construction is now complete, and the roof is in place.
During the final phase of the shell construction, it rained repeatedly, and several rooms have or had 1-2cm (0.4-0.8 inches) of standing water.
Some of the walls (Poroton masonry) are also damp. Perhaps water has entered the cavities of the bricks.
Will all this dry out on its own? Interior plastering is planned in about 3 weeks, and the screed in about 6 weeks.
I have also taken some photos.

It’s completely normal – set up a dehumidifier to remove the moisture.
Apply interior plaster only when the remaining moisture is below the levels specified by the manufacturer.
Talk to your site manager – this is practically everyday routine on a construction site.

A construction dehumidifier only makes sense once the windows and doors are installed.

Oh.
How long does a dryer need to run in this case?

For my flowing screed, I used 6m³ (about 213 cubic feet) of water... that brings a significant amount of moisture into the house.
It takes 2 to 5 years for it all to dry out completely.
Residual moisture remains in the wall plaster, screed, and foundation slab.
I’m also not a fan of drying devices (high electricity costs) and a "move-in date 4 months after the foundation slab."
I’d rather leave it standing a bit longer (without insulation, of course).

I don’t see any real water damage here, so I wouldn’t worry about it. Still, it’s a good idea to check with the trades involved to see if they are okay with it and consider it acceptable.
