Models

Step 1 sends drawing crops, so it needs a model that can see them. Steps 2 and 3 send step 1’s readings as text — a text-only model with a large context is a fair answer there.

This crop contains a bridge general arrangement with a plan at the top and an elevation at the bottom, rather than a single elevation view. It documents left and right bridge bent positions, walls, deck bearing/joint locations, railroad and future-track clearances, bridge length and bent-station information. The right edge includes a partial proposed vertical profile and a bent-elevations table; some note text is cut off by the crop boundary.

One set of distinct items across every page. The same bent read as “BENT”, “Interior bent” and “Bent No. 2” is one item here, carrying every page and crop it was seen in. One model call over all of step 1’s readings; the page mapping is resolved from its grouping rather than retyped by it.

3Match the ontology18 of 23 matched · 2 to check · 5 unmatchedconfigured openai/gpt-5.6-terra-pro · $1.00 → $6.00 per M · default

Every item from step 2 compared against the project’s engineering ontology, and then, for each one that lands in a class, a take-off of what that class asks for. The class list goes up as a closed vocabulary, so regional wording resolves without a synonym table — BENT to a pier system, PSC BEAM to a prestressed girder. Any class id that is not in the ontology is rejected rather than stored. The take-off reads every crop behind an item, derives what the drawings imply, shows its arithmetic, and says plainly when a number is not there. Matching against bridge v1.0.0, 133 classes.

78% of items placed. The 5 below fit no class — add one to the ontology and match again.

◈Index for the agentnot indexed · 192 points ready

Everything steps 1 and 2 know, written to the vector store for a chat agent to answer from. Cut fine — a point for each object, each measurement and each note, not one per crop — with the page, the crop and the drawing written into every one, so a retrieved number arrives with enough context to be an answer. The readings as a whole and step 2’s items are indexed too, for the questions that are about a drawing rather than a figure.

Re-runnable at any time: each point is keyed to the record it came from, so re-indexing replaces what changed, adds what is new, and drops what the drawings no longer support. Re-read a crop or correct one by hand, then press this.
