Welcome to Stratta
Query Swiss civil-engineering norms (SIA, Eurocodes) directly from Claude with exact, verifiable citations.
Stratta lets structural and civil engineers consult Swiss building norms (SIA standards and Eurocodes) straight from a conversation with Claude. You ask a question in plain language; Claude reads the relevant norms and answers with a precise citation to the exact section and page.
It works through a small program called an MCP server that you install once in your Claude client. After that, the norms become part of every conversation.
Install Stratta and ask your first question in under 5 minutes.

What you get#
Every technical claim is backed by [Norm path, p. XX]: pointing to a section Claude
actually opened, never invented.
Talk to Claude the way you already do. Stratta gives it the norms; you read the answer.
SIA distributes a rule across several norms (260, 261, domain-specific). Claude follows the cross-references so the answer is complete.
Norms are scoped to your organization. You bring the documents you are licensed for; no one else sees them.
How a session looks#
You ask
"According to SIA 261, which variable loads apply to an office floor, and how do I combine them at ULS?"
Claude navigates
Claude lists the available norms, opens the table of contents, reads the relevant sections, and follows cross-references to SIA 260 for the load combinations.
You get a cited answer
A clear answer with the governing values and a citation like
[SIA 261, 8.2, p. 44]you can open in the printed norm to verify.
