ᐅ Walls in the shell construction stage already affected by moss growth

Hello everyone,

We are currently, unfortunately still, in the shell construction phase and noticed during our last site visit that a wall, as shown in the pictures, is so wet because water is running down from the un-drained roof terrace that the wall on the first floor already has moss growth.

Is there a way to dry this wall quickly so that the plasterer can start soon?

Explanation:
The roof terrace on the second floor currently has no drainage apart from the outlet where water runs directly along the exterior wall; it was simply forgotten... as was the insulation of the roof terrace, which luckily we as the clients noticed in time.
The missing drainage only became apparent to us after the walls had already been built.

In the meantime, pipes have been laid in the floor for the drainage of the roof terrace, but the general contractor is ignoring the other issues.

What options do we have to dry the wall quickly, properly, and effectively?

Best regards,
M

OT:
It doesn’t seem to be an isolated case that the construction workers always forget to install the water diverters during the shell construction. In our case, there were none installed either, so we ended up adding them ourselves out of desperation. Our general contractor then scolded the tradesmen severely because, of course, the moisture caused delays.

First, the damage needs to be documented, and an expert must determine the causes – this will decide who has to cover the costs.

Then you need a specialist, which you can find in the business directory under "building protection." Trying to interpret photos in the forum would be speculative and too imprecise to plan the "remedy" here.
Thank you for the response. This helps me move forward for now.
