Could you build this?
Partial A document-handling interface is straightforward, but reliably extracting architectural drawings and cross-referencing plan check notices against localized municipal building codes requires heavy multimodal PDF analysis and deep civil engineering domain knowledge.
What it would actually take: Requires specialized computer vision and vector graphic parsers for multi-page architectural blueprints (CAD/DWG and high-res PDFs) combined with an indexed knowledge base of municipal municipal municipal building codes (IBC/IRC with local amendments). The pipeline demands fine-grained visual document QA and high-precision RAG to prevent costly structural or permitting errors.
