BauPlus: sovereignty score and 8 European alternatives

BauPlus is construction administration software from Heiniger & Partner AG, in two editions: for planners such as architects and civil engineers, and for contractors, timber builders and landscape gardeners. The planner edition supports cost estimation and control, specifications and tendering, quantity measurement, contract and invoice management and time recording. The contractor edition covers quotes, price calculation, day-work, reporting, invoicing with the Swiss QR-bill and post-calculation. Data can be exchanged in Swiss construction formats such as CRBX, and interfaces to accounting packages exist.

BauPlus runs on Windows and requires a Microsoft SQL database that you install yourself, so data stays in your own environment; the vendor does not describe a hosted service. Heiniger & Partner AG is based in Wetzikon, Switzerland. Switzerland is not an EU member state but is an EFTA country with an EU adequacy decision. No foreign parent company was found. The website's privacy notice is generic; ask about the arrangements for remote support.

Why digital sovereignty matters with BauPlus

BauPlus is headquartered in Switzerland and falls under Swiss law, including the revised Swiss data protection act. Switzerland is not an EU member, but the European Commission recognises its level of data protection as adequate. Its Swiss headquarters does not by itself bring it under US legislation such as the CLOUD Act.

BauPlus runs on infrastructure you choose and control yourself. You decide where the data lives, including fully within the EU if you want — this is not a fixed hosting choice made by the vendor.

BauPlus is closed source, but you run the software yourself on your own infrastructure. The encryption keys and the runtime therefore stay under your own control, though you cannot audit or modify the source code. Ask about export options and open standards to limit software-level lock-in.

What this means for your organisation depends on your whole stack and context. The free assessment weighs BauPlus together with your other vendors and gives a total score, a heatmap and the main risk drivers.
