DIN Standards Committee Building and Civil Engineering

About NABau

The DIN Standards Committee Building and Civil Engineering (NABau) is responsible for considering all proposals for standardization in the field of building and civil engineering and for processing such proposals whenever there is a legitimate interest in standardization and guaranteed funding is available to cover the associated operating costs incurred by the committee.

In addition to national standards, the NABau participates in European and international standardization in its field of work. It is also responsible for promoting the preparation and application of the relevant standards.
