About D83 files
A .D83 file is a specialized data exchange format used primarily in the German construction industry to transmit Bill of Quantities (BoQ) and tender request data. Dictated by the GAEB (Gemeinsamer Ausschuss Elektronik im Bauwesen) standard, it allows architects and planners to send structured service descriptions to contractors for pricing. These files are typically opened and managed using specialized AVA (Ausschreibung, Vergabe und Abrechnung) software such as those provided by Softtech or other regional vendors. The primary disadvantage of the .D83 format is its highly restrictive and localized nature. Receiving one of these files without possessing a costly, dedicated AVA software license makes the tender completely inaccessible, as standard text editors cannot parse the hierarchical line-item structures into readable formats. Furthermore, the format is practically useless for stakeholders outside the DACH region construction sector. To bypass these limitations, users frequently need to convert the data. For universal reading, printing, and archiving, convert the .D83 to PDF. For active calculation, cost estimation, and sharing with subcontractors, convert the file to XLSX or CSV so it can be manipulated in Excel. Once calculations are complete, the data is typically converted into a .D84 file for final bid submission.
