ᐅ All the wastewater pipes in the foundation slab are incorrectly installed.

ScPcEcPcWe are fulfilling our dream home, but things are taking a very negative turn – I am truly desperate!
Our concrete slab was poured last week – the site manager even personally received the workers in the morning for this. A few days later, when the tarp was removed, we saw that all the pipes had been installed incorrectly. The multi-utility house entry was also misplaced. It was as if the floor plan had been rotated 90 degrees to the left. The site manager responded immediately and came on Monday, but his statements made us uneasy... he said it wasn’t a big problem… the pipes would be covered with concrete and we would make core drillings???
Now our question is: is it possible to properly install all the pipes afterwards? What solutions should we accept? Can we insist on a new foundation slab? Our trust is already severely shaken, and on top of that, they delivered facing bricks that look as if they were painted with nail polish… some are already chipping, revealing the red color underneath (our house is supposed to have dark facing bricks). His argument was… you can’t see that on the wall, they don’t absorb much water 🙁 Our house will cost about 300,000€… I am sad that we have been treated this way so far…

This can become a never-ending story, so:
Bring an expert on board.
They can advise you on waterproofing and more.
Here in the forum, we can only guess, for example, whether you have a waterproof concrete slab (WU slab), what the local utilities say about core drilling, whether insulation under the slab is problematic, or if the facing bricks only have minor chips, etc.
Sometimes the facing bricks are used as half bricks, so some imperfections don’t matter—the bricks can be cut accordingly, for example.
Who selected the bricks?

And in the future, involve an independent expert to inspect the construction at key milestones.
My concrete slab was also poured last week, and I had my expert on site two days before. For example, I had a wastewater pipe that was only 1.38 m (4.53 ft) away from the exterior wall instead of 1.5 m (4.92 ft). This was identified before the concrete was poured, so theoretically it could still have been corrected. In my case, it was still acceptable because the deviation was in a direction that was not critical. But if there had been more deviations or if they had been more critical, they would have had to be addressed again. That would probably have delayed the concreting until the next year, which would have really annoyed my construction manager, but it wouldn’t have helped otherwise.
So, I can only recommend consulting a specialist. They also know which construction phases are most sensible for an inspection.

The shell builders simply rotated the house by 90 degrees and dug the strip foundations accordingly. The expert didn’t notice, it was my ex-wife who caught it. That’s when we immediately fired him and took over the site management ourselves :p. Fortunately, it was just a bit of digging since the concrete slab was poured a few days later.
Once the concrete slab is in place, core drilling becomes difficult. It depends on its location. If strip foundations are present or drainage pipes run through the center of the house, demolition and rebuilding might be more practical.
