ᐅ Shell construction company builds basement smaller than in the approved building plans

Hello everyone,
A shell construction company was commissioned to build the basement with in-situ concrete according to the existing factory plan (14.0 x 6.66 m (46 ft x 21.8 ft)). However, the company missed the dimensions and built the basement about 4 cm (1.6 inches) smaller. This applies to both the exterior and interior measurements.
Dimensions according to factory plan
Target house width: 6.66 m (21.8 ft)
Target width of basement concrete walls exterior: 6.525 m (21.4 ft)
Target width of basement concrete walls interior: 6.025 m (19.8 ft)
Actual width of basement concrete walls exterior: 6.48 m (21.3 ft) (-0.04 m (-1.6 inches))
Actual width of basement concrete walls interior: 5.96 m (19.6 ft) (-0.06 m (-2.4 inches))
I measured myself using various tape measures and a laser distance meter.
What should be done in this situation?
Price reduction due to smaller total area? If so, how much? Are there any standard tables or guidelines for this?
It is especially unfortunate that the house was built smaller on the narrow side (maximum size restricted by the zoning/land-use plan), where every centimeter counts.
This also has consequences such as the possible need to adjust the factory plan (staircase, adjacent walls, support columns no longer fit).
Best regards

You recently created a thread because the concrete cover was clearly too small. Now the structural shell has also gone off track dimension-wise.
What kind of advice are you expecting here in this new thread? Put this all on the list for the expert (and possibly a lawyer) and finally get professional advice.
Please don’t take it personally, but you do come across as a bit resistant to advice.

The insulation between the semi-detached houses is 2 cm (about 0.8 inches) on each side (total 4 cm (1.6 inches)), but it is compressed by the in-situ concrete. This does not really matter because the corners were probably simply laid out incorrectly.In my opinion, this is a far bigger issue than a basement that might be a few millimeters too small. Over-poured construction joints between buildings can cause significant problems with impact sound transmission. It is urgently recommended to consult an expert. Right now, while there is still no house built on top, relatively cost-effective corrective measures can still be taken.MayrCh schrieb:
Overcast building expansion joints can lead to significant issues with impact sound transmission. The building expansion joint is present and is not overcast. The basement concrete wall is shorter than planned.domino55 schrieb:
The control joint is in place; it has not been over-poured with concrete. The basement concrete wall is shorter than planned. For goodness’ sake, please answer the questions already. It’s really exhausting having to extract every detail from you.
I’m guessing you don’t like the answers, which are:
- I planned everything myself; there is no professional construction supervision
- I ordered the staircase proactively based on the plans
- There was no tender; the offer just says “rough construction thrown together” without details, and the lowest bid was awarded
Prove me wrong 🙂

karl.jonas29 Jan 2023 17:43A simple question (and because the same question from @NatureSys was not answered): (Why) can’t the ground floor be built exactly as planned? It just slightly extends over the basement (this was previously called "structural timber protection" on the upper floor 🙂 ).
