Basic Services vs Additional Services
According to HOAI: Services Overview for Architecture & Interiors (2021)
Annex 10 (from §34 Paragraph 4, §35 Paragraph 7)
The HOAI defines two categories of services that are carried out in the various phases. On the one hand, there are the basic services that are required for every project and are included in the basic fee. In addition, there is a list of detailed services that can be agreed in addition to the basic fee. These include, for example, renderings, 3D models (BIM), feasibility studies and the use of specialists for special work on your building.
