Good day,
I am a master’s student at Bauhaus University Weimar. I am currently working on my master’s thesis. I have some questions to ask. Any help would be greatly appreciated.
1. Which documents are sent to the planning department for the building permit?
2. Are they sent as drawings or 3D models?
3. How does the planning department check whether the escape and rescue routes comply with regulations?
4. How does the planning department inform the designer about the issues contained in the drawings or the model?

Thank you very much for your time.

Since I am unsure whether this is a serious post (studierende männliche Meisterschülerin?), a few counter-questions:
- What are you studying?
- What is the topic of your master's thesis?
- Are you familiar with the Baugesetzbuch?
- Are you familiar with the Landesbauordnung?

I am studying a Master's in Natural Hazards and Risks in Building Construction. My Master's thesis deals with the object-based model review of the building regulatory provisions. Yes, I am familiar with the Building Code and State Building Regulations. But the procedure is not described in detail there. Only which types of permits we have. I want to know how it works in a real scenario.

Ah, BIM, brave new world. As long as not even 16 federal states can agree on a unified state building code, an automated calculation of setback distances is already doomed; so the digital lifecycle model of a building including the digital approval process will probably still take a while. But well, visions have to exist.

Today, things mostly still run like this in NRW, using the example of a simple single-family house according to §64 Building Code NRW, without special features with a development plan and optional surveyor:
- Surveyor downloads the cadastral data in NAS format from the cadastral authority’s server, integrates the analog/digital development plan and the conducted topographical survey, and sends the preliminary site plan as a DWG to the authorized applicant
- Authorized applicant creates floor plans, elevations, sections and sends them as DWG files to the surveyor
- Surveyor adds the projected building to his site plan, calculates setback distances, floor area ratio, gross floor area ratio, proof of number of storeys and provides five printed copies to the authorized applicant
- Authorized applicant fills out the forms (building application, building description, statistics, exemption request...) according to the state building code and prints floor plans, elevations, sections fivefold
- One package goes to the builder, one remains with the authorized applicant, and three go to the approval authority
- this authority involves other authorities (case-dependent, e.g., municipality, environmental office, survey office, land registry office, planning office, civil engineering office) by sending copies by post
- after evaluation of the comments and completion of the review, the building permit is issued by official notice to the builder

Are 1. and 2. thereby answered?
3. What exactly do you mean? For example, in the attic of a single-family house, it is checked whether the roof window is large enough and the parapet height is low enough to serve as a second rescue route. For larger halls, the planner has to enter the escape route lengths within the fire compartments into the plans. For large projects, a fire protection report is required.
4. The builder receives a letter with the detected defects and a request to remedy them within a deadline. A copy is sent to the authorized applicant.

Lots of text and yet incomplete. For more detailed information, I recommend an internship in an architectural office or at an approval authority.

There are even one or two municipalities that know and use the digital signature!

Thank you very much for your explanation and time. Do you have a source for all these explanations so that I can read or cite in detail? An internship is not an option now, as I am currently in the middle of my master's thesis. Once again, I am very grateful for your time and help.

Professional experience.
The other important sources I have already mentioned: Building Code and Building Regulations NRW. In this respect, the BauPrüfVO is of course also essential in NRW, which in other federal states is usually called BauVorlVO.
For the exact procedure, each municipality can set its own rules - in writing or by oral tradition. However, these are not generally binding. Long live federalism!
