The archive as a whole consists of three sections:
- technical and administrative section;
- design section;
- photographic section.
1. Technical and administrative section
The technical and administrative section, catalogued according to the international archival
standards ISAD(G) and ISAAR(CPF), adapted for electronic use and available online, is the most
articulated and substantial part of the archive. It consists of files concerning design work and the
administration of works. Its extent is around 4,300 archival units, held in some 1,950 boxes, for an
approximate total of 300 linear metres.
2. Design section
The second section consists of design drawings kept in tubes or in large-format cases. For the most
part these are original drawings on tracing paper, amounting to around 6,900 storage units, for a total
of approximately 400 linear metres.
3. Photographic section
A third section, finally, comprises heterogeneous material: photographic documentation, cine film,
audiovisual material on magnetic media, technical monographs and periodicals, and computer media. Its
extent in this case is around 9,500 documentary units.
