ISO 21723:2019 PDF Download

ISO 21723:2019 is a standard that provides guidelines for modular coordination in buildings and civil engineering works. It defines the values of the basic module, which is a standardized unit of measurement used for coordinating dimensions in modular construction. The standard also specifies the values of multimodules for horizontal coordinating dimensions, which are combinations of basic modules, and sub-modular increments, which are smaller units for fine-tuning dimensions.

In addition, ISO 21723:2019 outlines the preferred vertical modular dimensions, which are vertical heights that are compatible with the modular system. It also establishes a series of preferred multimodular sizes for horizontal dimensions, ensuring that different types of building elements can be easily coordinated and integrated within the modular system.
