NOTE The material is arranged, to the extent possible, by project.
The arrangement of the projects is based on the old works list numbering (see request number 615). The request numbers of the documents (written documents, drawings, photographs, slides, negatives and the documentation) correspond to the original work numbers. Not all projects had a work number; these projects have been assigned a request number above 500.
The order of the old work numbers can be considered more or less chronological. The projects without work numbers are placed between the projects with work numbers in the corresponding years.

The descriptions consist of the following parts:
- work number;
- project description;
- indication of the nature of the documents with the corresponding application numbers;
- and finally an explanatory note if necessary; the information on the drawings is taken from the sheets.
