Initiative for the transmission of digital data by administrative units to the competent municipalities in the context of building permit procedures. It is now the practice for the administrative unit to invite the competent municipality to notify its participation in the administrative act in building permit procedures. The administrative units, although they also receive a digital copy of the project documentation, refuse to send it to the municipalities, and the parties applying for a building permit are obliged to order (and pay for) an additional physical (paper) copy of the documentation from the designer.
