Brownfield drawings into structured data.

A brownfield project starts with a drawing package that was authored years or decades ago and has aged unevenly. Some sheets are clean CAD exports. Some are scans of the original paper drawings, faded, folded, and stamped with revision notes added after the fact. Some are photos a field engineer took of the wall in the operations building. The tag convention is whatever the facility has used since commissioning, which may or may not match any published standard.

The job is to turn that package into the same set of structured documents a greenfield project would produce in the engineering phase: an I/O list to size the controllers, an equipment list to bound the scope, and a line list to coordinate with piping. The conventional path is a junior engineer with a spreadsheet, a printed copy of the drawings, and three to four weeks of transcription.

Tagsight collapses the transcription. The drawing package uploads to a workspace. Vector PDFs read fastest because the tag text resolves directly off the page; scans are read at high resolution; photo uploads are deskewed and run as inputs. Every row carries the source-page reference. You review and confirm each row, jumping back to the source page in two clicks to edit inline. The exports run on the reviewed data, in the tag convention the drawings were authored in.
