Construction defects - Damage control?

The builder is the structural engineer or general contractor in AT.

The Baumeister in AT is the shell builder or general contractor.

No. The Baumeister is a protected professional title in AT. He is allowed to plan, calculate static loads, determine costs, and manage the construction. Compared to Germany, he is a kind of practicing architect, to distinguish him from the desk worker. Perhaps more like a civil engineer.

Where this role is located is, as in D, different. If you build with a general contractor, they will have a Baumeister; if you build with individual trades, you have one.

In the basement, almost 50 cm of groundwater stood in the dense concrete basement for over 2 weeks in June 2019. 2. Bricks not according to Wienerberger guidelines (instead of thin-bed mortar, 5 mm and wider joints). 3. Flat roof incorrectly executed - slope insulation not according to the installation plan and then cut to create a slope. 4. Basement was dug more than 50 cm too shallow - consequence: house is too high according to the small garden law. Not consolidated.

1. Are you really completely sure that it was groundwater? Why is there nothing standing there anymore now, what was changed? What does the expert advise? 2. So what? In the worst case, you have thermal bridges. Will there be an ETICS in front of it? Or do you have a justified fear for the statics? 3. What exactly are you afraid of here? 4. That is more than unfortunate. What does the expert advise here? Is it possibly an option to suggest to the authority to slightly raise the terrain from the street side so that the maximum height above ground level is not exceeded? This would at least prevent a precedent case that neighbors could refer to.

How can something like that be explained? Why do problems only occur after 10 years?

can you explain that again?

I don't know the details. The [WU Keller] is now leaking after 10 years. I also wonder how that can be, that's exactly why you build a [WU Keller], so you can have peace for decades.

But the colleague had to pump out several liters daily from time to time. Everything down there is just ruined. Something is supposed to be injected somewhere inside now.

Then the builder should have noticed the mistakes. Especially if he was commissioned by the [TE].

What does this builder and the expert say?
