/Concrete staircase
Concrete stairs, whether cast or prefabricated, are even more problematic when installed during construction.
Builders pour screeds on both the first floor and the floors above. However, they don't take the staircase itself into account. The screed under parquet or tile is always a few centimeters thick. The risers of the first and subsequent steps immediately become different: the first step is low, and the last is very high. If you start pouring the steps, the angle of the staircase itself changes. They also don't take into account the riser gaps, the amount of overlap between each step, and the required thickness of the underlay between the concrete and the wooden step.
Often, people don't look where they're stepping when walking, and if the dimensions "vary," they can trip and fall.
A design error of even 1 cm can ultimately lead to tens of centimeters in changes in the angle or the addition of an extra step.
It's like a snowball. This becomes apparent when finishing the staircase base, which is what the steps are supported on. The width of this base, when viewed from the side, looks crooked and uneven. The severe railing and paint only highlight these imperfections.
