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

6.66 m (22 feet) can easily be measured precisely with a tape measure or folding rule. There is no need for a surveyor.
Mistakes happen. If the measurements are very important to me, I measure them myself.
Now to the solution. The staircase is probably located along the wall to the neighbor, so there should be no issue there. The masonry work above the basement can still be carried out as planned. The bricks just protrude a few millimeters further. If necessary, you could make the basement insulation slightly thicker. I would call that a win-win situation.
If the structural requirements for the brick do not allow it, then an L profile can simply be attached to the concrete.

These are concrete stairs that need to be custom ordered in advance; otherwise, you lose a lot of unnecessary time. Who ordered the stairs? You or the shell contractor?
