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.

Applied to the reading

  • objects · foundation outline — “tapered trapezoidal · ×2” → “skewed rectangular · ×2”Dimension LF Agent: Each visible foundation cap has opposite parallel sides in this plan crop; no taper is drawn.
  • measurements · Chainage = 64+400 — “Chainage = 64+400 — on RET. TOE WALL” → “Chainage = 64+400 — on key-plan alignment”Dimension LF Agent: 64+400 is a chainage printed along the alignment in the key plan, not a dimension of the separately leader-called-out RET. TOE WALL.

Applied to the reading

  • measurements · Depth of BRG. & PEDESTAL — “400 mm — on piercap” → “400 mm — on bearing & pedestal”Dimension LF Agent: Note 16 states that the piercap top level was fixed considering the "400mm DEPTH OF BRG. & PEDESTAL"; it does not dimension the piercap as 400 mm.

Proposed and rejected

  • objects · reinforcing steel bars — removedReinforcement Agent said: Note 7 is a general reinforcing-steel material specification only; this notes crop does not detail reinforcing bars as a separate object.Rejected — Note 7 expressly specifies “ALL REINFORCING STEEL” as high-yield-strength deformed (TMT) bars of Grade-Fe 550D conforming to IS:1786, supporting the reinforcing-steel-bars object.

Universal Validator’s reasoning

The crop explicitly specifies reinforcing steel bars as TMT bars, so that object is supported. It also identifies 400 mm as the depth of the bearing and pedestal considered for fixing the piercap top level, rather than a piercap dimension.

Which agents were considered

  • Reinforcement Agentrankeyword "reinforcement", "reinforcing", "bars" in the reading
  • Concrete Agentrankeyword "concrete", "precast", "psc" in the reading
  • Dimension LF Agentrankeyword "elevation", "thickness" in the reading

What each agent cost

  • Reinforcement Agent1 proposedThe crop lists reinforcing steel only as a general material specification and provides no reinforcement detailing, bar marks, sizes, counts, or layout. It therefore should not be recorded as a separate object. · openai/gpt-5.6-terra-pro · 25544 tokens · 15.1s
  • Concrete Agent0 proposedThe reading correctly preserves the printed concrete grades as material classes, the clear-cover values as covers, and the 400 mm/200 mm bearing-pedestal note as stated. No concrete dimensions, quantities, or materials have been incorrectly re-read in this crop. · openai/gpt-5.6-terra-pro · 23368 tokens · 10.2s
  • Dimension LF Agent1 proposedThe 400 mm value is stated as the combined depth of the bearing and pedestal, not as a piercap dimension. The remaining readings match the printed general notes. · openai/gpt-5.6-terra-pro · 25408 tokens · 19.7s

Applied to the reading

  • measurements · abutment reinforcement spacing — “1000” → “1000 — dimension shown within the A1/A2 abutment wall area”Reinforcement Agent: Although 1000 is dimensioned in the abutment-wall region, this crop does not identify that dimension as reinforcement spacing.
  • objects · deck slab — “Deck is called out with 2.5% slope and 50mm THK. (WC).” → “Deck is called out as RCC CAST IN SITU DECK with 2.5% slope; the adjacent 50mm THK. (WC) callout applies to the wearing course.”Concrete Agent: The crop labels the concrete member "RCC CAST IN SITU DECK SLOPE 2.5%" and separately labels "50mm THK. (WC)," so 50mm is not a deck-slab thickness.

Proposed and rejected

  • measurements · centreline of proposed road — “centreline of proposed road = 29000” → “centreline station of proposed road = 29000”Dimension LF Agent said: In this crop, 29000 is printed directly with the “C/L OF PROPOSED ROAD” annotation rather than between dimension extension lines; it identifies the road centreline station, not a length dimension.Rejected — The crop prints "C/L OF PROPOSED ROAD" with 29000, but it does not print or otherwise identify 29000 as a station. Calling it a centreline station adds an unsupported interpretation.

Universal Validator’s reasoning

I relied only on the printed callouts and dimension graphics visible in the crop. The deck and wearing-course annotations are separate, while the crop does not expressly identify 29000 as a station.

  • Dimension LF Agentrankeyword "spacing", "elevation", "thickness" in the reading

What each agent cost

  • Reinforcement Agent1 proposedThe crop prints 1000 dimensions within the abutment wall area, but it contains no reinforcement callout, bar mark, bar size, or spacing notation identifying them as reinforcement spacing. · openai/gpt-5.6-terra-pro · 27349 tokens · 24.5s
  • Concrete Agent1 proposedThe 50mm thickness callout is explicitly for the wearing course (WC), not for the RCC cast-in-situ deck. The deck itself is called out as RCC with a 2.5% slope, but no deck thickness is printed in this crop. · openai/gpt-5.6-terra-pro · 23926 tokens · 14.9s
  • Dimension LF Agent1 proposedThe 29000 printed beneath “C/L OF PROPOSED ROAD” is a road centreline station annotation, not a member or roadway length. The remaining readings match the dimensions, level callouts, and objects shown in the two sections. · openai/gpt-5.6-terra-pro · 32377 tokens · 44.1s

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.

A round proposed nothing new, so the grouping has settled.

Round 1 · 35 items in · 1 applied

  • Over-merge Agent0 proposedThe grouping keeps distinct constructional items separate: piles are not combined with pile caps, pier caps, bearings, or approach slabs, and no item mixes materials, classes, or trades.
  • Under-merge Agent1 proposed“Pile Foundation” is the generic drawing name for the bored cast-in-situ pile foundation already identified as Bored Cast-in-situ Pile; it does not indicate a separate foundation component such as a pile cap.
  • Merged “Pile Foundation” into “Bored Cast-in-situ Pile”Under-merge Agent: The drawings’ generic “Pile Foundation” reference denotes the same pile work called “pile” and “bored cast-in-situ piles” under item 2; the pile cap remains separately identified in item 5.

Round 2 · 34 items in · nothing proposed

  • Over-merge Agent0 proposedThe principal structural items are kept distinct as the drawings name them: pile versus pile cap, pier versus pier cap, deck slab versus approach slab, and bearings versus their supporting substructure. No listed item improperly combines separate constructional items or trades.
  • Under-merge Agent0 proposedThe grouping is right: the listed aliases are regional, abbreviated, plural, or formatting variants of their parent items, while similarly named elements such as Pier/Pier Cap, Pile/Pile Cap, and Deck Slab/Approach Slab remain distinct constructional items.

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.

83% of items placed. The 6 below fit no class — add one to the ontology and match again.

◈Index for the agentnot indexed · 428 points readyopenai/text-embedding-3-small

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.
