Swiss specifics

What is different in Switzerland

Architecture software

The Swiss market imposes requirements that an international solution usually lacks — it is built for other legal systems. Buy from abroad and you notice at the year-end close, in the VAT filing or with the first payroll declaration. These are the points that decide in this category:

This category lists only vendors with a Swiss legal entity. Foreign solutions are not excluded — none of those that matter here names a franc price.

SIA project phasesRegulation 102 of the Swiss Society of Engineers and Architects divides a project into phases from strategic planning to operation and allocates the fee across them in percentages. Billing that way requires a project structure, progress tracking and partial invoicing per phase.
NPK bill of quantitiesThe CRB standard item catalogue supplies the standardised texts used to tender construction work. Tendering that way lets you compare bids item by item — software must import the catalogues and carry the items through to settlement.
Cost plan BKP / eBKPThe Swiss building cost plan groups construction costs into standardised classes; the element-based eBKP under SN 506 511 does the same by building element. Architecture software calculates estimate, tender and settlement in that structure so the figures stay comparable across project phases.
Ten-year retentionThe Swiss Code of Obligations requires ten years of audit-proof retention – including readability. Clarify what happens to your data after you cancel.
Export and exitBefore signing up, check what an export looks like (entries, documents, master data). A solution without a usable export is a one-way street.
