Our Data Sources
Trust is the foundation of civil engineering. At IS Code.ai, we are completely transparent about where our answers come from and how our data is structured.
Primary Sources
All text, tables, and provisions retrieved by our AI are sourced directly from the official publications of the Bureau of Indian Standards (BIS). We do not use third-party summaries, student notes, or unverified web articles.
- Official IS Code PDFs and Hardcopies
- Official BIS Amendments and Revisions
- National Building Code (NBC) provisions where applicable
The Ingestion Process
PDF documents are notoriously difficult for AI to parse, especially engineering tables and complex formulas. We employ a proprietary multi-pass ingestion pipeline:
- Optical Character Recognition (OCR): High-fidelity extraction of raw text from official documents.
- Table & Math Reconstruction: Complex structural tables and formulas are manually verified and converted into strict Markdown/LaTeX schemas to prevent AI hallucination.
- Semantic Chunking: The codes are broken down clause-by-clause. Clause 26.2.1 is distinctly separated from Clause 26.2.2.
- Vectorization: The chunks are embedded into a high-dimensional vector database for instantaneous semantic retrieval.

Data Currency
We continuously monitor the BIS portal for new amendments. Our platform clearly indicates the "Year / Edition" of the code being cited. If a clause has been modified by an amendment, the AI is programmed to retrieve the amended text.
