Installation tolerance is the permissible range dimensional and positional deviations of building elements. It is taken into account at the design and implementation stage to ensure that the individual components are correctly assembled and work together. It is a consciously adopted technical parameter, not a manufacturing error, and is an integral part of the design and assembly documentation.
It includes both deviations resulting from the accuracy of the components and from transport conditions and assembly of the modular house on site. The assembly tolerance is important for the correct joining of the modules, the tightness of the connections and the load transfer in the structure.
Its values are determined on the basis of standards, design experience and adopted construction technology. If they are exceeded, this can lead to structural, assembly or operational problems. In modular construction, proper management of assembly tolerances reduces the need for adjustments at the installation stage. It also affects the final quality and durability of the building.
