Intake

Dropbox / CAST BUILD A.O export / Telegram attachments enter the approved project boundary.

Classify

Sort drawings, specs, RFIs, submittals, permits, budget files, photos, and scanned logs.

Extract

Use OCR/text parsers to recover text, tables, title blocks, sheet metadata, and cost codes.

Publish

Load searchable registers into CAST Build pages for review, filters, reconciliation, and reporting.

Where this plugs into Alüm

CAST Build area	What the tools add	Current status
Drawing Register	OCR/title-block extraction for sheets that are scanned or poorly text-layered.	Next pass
Specs + Permits	Searchable text, sections, tables, dates, agency comments, and review flags.	Ready to ingest
RFIs/Submittals	Extract embedded tables, responses, product names, due dates, and referenced sheets.	Indexed logs live
Budget / Changes	Use OCR only when exports are screenshots or scanned; prefer CSV/PDF text when available.	Exact register live
Drawing Analysis	Experimental dimension/symbol/takeoff support. Review before applying to private or critical docs.	Caution

Guardrail: OCR and drawing analysis are assistive. Anything affecting cost, scope, code, life safety, structure, or permits still needs human/consultant verification.
