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

  • measurements · Depth from top flange soffit to bottom bulb taper — “Depth from top flange soffit to bottom bulb taper = 1950 — on Mid section girder” → “Vertical depth between the bottom of the top transition and the start of the bottom flare = 1950 — on Mid section girder”Reinforcement Agent: In the mid-section drawing, the 1950 dimension starts at the same level as the lower end of the separately dimensioned 100 top transition, not at the soffit of the 150-thick top flange.
  • measurements · Depth from top flange soffit to bottom bulb taper — “1950 — on Mid section girder” → “Web depth from below top haunch to top of bottom flare = 1950 — on Mid section girder”Dimension LF Agent: In this crop, the 1950 vertical dimension starts at the web immediately below the 100 top-haunch dimension, rather than at the underside (soffit) of the 150-deep top flange.

Universal Validator’s reasoning

The 1950 dimension is visibly bounded by the level below the separately dimensioned 100 top transition and the level at which the bottom flare starts; it does not start at the top-flange soffit.

What each agent cost

  • Reinforcement Agent1 proposedThe 1950 dimension in the mid section does not run from the top-flange soffit; its upper extension is at the bottom of the 100-deep top transition. All other listed section dimensions and scales are supported by this crop. · openai/gpt-5.6-terra-pro · 15240 tokens · 27.5s
  • Concrete Agent0 proposedThe printed section geometry, dimensions, scale, and PSC concrete identification are read correctly. However, neither section carries a printed quantity/count, so the “×1” entries should not be retained for BOQ use. · openai/gpt-5.6-terra-pro · 17508 tokens · 36.5s
  • Dimension LF Agent1 proposedThe 1950 dimension on the mid section is not taken from the top-flange soffit: its upper extension is at the bottom of the 100-deep top haunch, and its lower extension is at the start of the bottom flare. · openai/gpt-5.6-terra-pro · 17913 tokens · 46.9s

Applied to the reading

  • measurements · Pile spacing — “3600 — on Abutment pile cap A2 (2 spaces shown)” → “3600 — on Abutment pile cap A2 (3 spaces shown)”Concrete Agent: The A2 pile-cap dimension string visibly contains three separate 3600 spaces between the 750 end offsets.
  • objects · A1 — “Wall type abutment · rectangular wall with tapered front face · reinforced concrete · ×1 · Left abutment, marked A1; labelled 'WALL TYPE ABUTMENT' on right side” → “Wall type abutment · rectangular wall with tapered front face · ×1 · Left abutment, marked A1; labelled 'WALL TYPE ABUTMENT' on right side”Concrete Agent: The crop labels the abutment "WALL TYPE ABUTMENT" but does not print RCC or concrete for the abutment.
  • objects · A2 — “Wall type abutment · rectangular wall with tapered front face · reinforced concrete · ×1 · Right abutment, marked A2” → “Wall type abutment · rectangular wall with tapered front face · ×1 · Right abutment, marked A2”Concrete Agent: The crop identifies A2 as a wall type abutment, but no RCC or concrete material designation is printed against it.
  • objects · Pile cap — “Pile cap · rectangular · reinforced concrete · ×3 · One under each abutment (12300 wide) and one under pier P1 (5100 wide)” → “Pile cap · rectangular · ×3 · One under each abutment (12300 wide) and one under pier P1 (5100 wide)”Concrete Agent: Pile caps and their dimensions are drawn, but the crop does not print a concrete or RCC material callout for the pile caps.
  • objects · Deck slab with deck continuity — “Deck slab with deck continuity · flat slab · reinforced concrete · ×1 · 'DECK CONTINUITY' called out over pier P1” → “Deck slab with deck continuity · flat slab · ×1 · 'DECK CONTINUITY' called out over pier P1”Concrete Agent: "DECK CONTINUITY" is printed over P1, but the crop does not print an RCC or concrete material designation for the deck slab.
  • objects · Approach slab — “Approach slab · rectangular slab · reinforced concrete · ×2 · 300 THK. with 150 THK. PCC levelling course beneath” → “Approach slab · rectangular slab · ×2 · 300 THK. with 150 THK. PCC levelling course beneath”Concrete Agent: The crop prints "300 THK. APPROACH SLAB" but does not identify the approach slab itself as RCC or concrete; PCC is printed only for the levelling course.
  • objects · Independent retaining wall — “Independent retaining wall · vertical wall · reinforced concrete · ×2 · Called out at both approaches” → “Independent retaining wall · vertical wall · ×2 · Called out at both approaches”Concrete Agent: "INDEPENDENT RETAINING WALL" is called out at the approaches, without a printed RCC or concrete material designation.
  • objects · Bearing pedestal — “Bearing pedestal · rectangular block · reinforced concrete · Shown under bearings; mentioned in cut-off notes list” → “Bearing pedestal · rectangular block · concrete · Shown under bearings; mentioned in cut-off notes list”Concrete Agent: The visible notes place "BEARING PEDESTAL" under "GRADE OF CONCRETE," supporting concrete, but do not print that it is reinforced concrete.
  • measurements · Span length (C/L exp. joint to C/L exp. joint), left span — “40000(SQ) 46188(SK) — on Span A1-P1” → “Span length (C/L exp. joint to C/L pier), left span = 40000(SQ) 46188(SK) — on Span A1-P1”Dimension LF Agent: The upper left-span dimension runs from the A1 C/L OF EXP. JOINT line to the P1 centreline; P1 has no expansion-joint line.
  • measurements · Span length, right span — “46000(SK) 46188(SK) — on Span P1-A2” → “Span length (C/L pier to C/L exp. joint), right span = 46000(SK) 46188(SK) — on Span P1-A2”Dimension LF Agent: The upper right-span dimension starts at the P1 centreline and ends at the A2 C/L OF EXP. JOINT line.
  • measurements · Pile spacing — on Abutment pile cap A2 — “3600 — on Abutment pile cap A2 (2 spaces shown)” → “3600 — on Abutment pile cap A2 (3 spaces shown)”Dimension LF Agent: The A2 pile-cap dimension string visibly reads 750, 3600, 3600, 3600, 750, so it contains three 3600 spacings.
  • measurements · Pile cap overall width — on Abutment pile cap A1 — “12300 — on Abutment pile cap A1” → “Pile cap overall length = 12300 — on Abutment pile cap A1”Dimension LF Agent: The 12300 dimension is drawn horizontally along the pile cap in this longitudinal elevation, as the total of the edge offsets and pile spacings; the crop does not show a transverse width dimension.
  • measurements · Pile cap overall width — on Abutment pile cap A2 — “12300 — on Abutment pile cap A2” → “Pile cap overall length = 12300 — on Abutment pile cap A2”Dimension LF Agent: The 12300 dimension is drawn horizontally along the pile cap in this longitudinal elevation, as the total of the edge offsets and pile spacings; the crop does not show a transverse width dimension.
  • measurements · Pier pile cap overall width — on P1 — “5100 — on P1” → “Pier pile cap overall length = 5100 — on P1”Dimension LF Agent: The 5100 dimension is the horizontal overall dimension of the P1 pile cap in the elevation, made up of 750, 3600 and 750.
  • objects · A1 — “Wall type abutment · rectangular wall with tapered front face · reinforced concrete · ×1 · Left abutment, marked A1; labelled 'WALL TYPE ABUTMENT' on right side” → “Wall type abutment · rectangular wall with tapered front face · ×1 · Left abutment, marked A1; labelled 'WALL TYPE ABUTMENT' on right side”Dimension LF Agent: The crop labels the abutment WALL TYPE ABUTMENT but does not print its material.
  • objects · A2 — “Wall type abutment · rectangular wall with tapered front face · reinforced concrete · ×1 · Right abutment, marked A2” → “Wall type abutment · rectangular wall with tapered front face · ×1 · Right abutment, marked A2”Dimension LF Agent: The crop shows A2 as a wall type abutment but does not print a material designation for it.
  • objects · Pile cap — “Pile cap · rectangular · reinforced concrete · ×3 · One under each abutment (12300 wide) and one under pier P1 (5100 wide)” → “Pile cap · rectangular · ×3 · One under each abutment (12300 overall) and one under pier P1 (5100 overall)”Dimension LF Agent: No pile-cap material is printed, and the shown horizontal dimensions are overall dimensions in elevation rather than widths.
  • objects · Cast in situ bored pile — “Cast in situ bored pile · circular · reinforced concrete · 1200 dia; shown in groups under abutment caps (spacings 3600, 3600, 3600) and pier cap (3600); only elevation projection visible so true number not countable” → “Cast in situ pile · circular · reinforced concrete · 1200 dia; shown in groups under abutment caps (spacings 3600, 3600, 3600) and pier cap (3600); only elevation projection visible so true number not countable”Dimension LF Agent: The printed callout is "1200Ø RCC CAST IN SITU PILE (TYP.)"; it does not identify the piles as bored.
  • objects · Deck slab with deck continuity — “Deck slab with deck continuity · flat slab · reinforced concrete · ×1 · 'DECK CONTINUITY' called out over pier P1” → “Deck slab with deck continuity · flat slab · ×1 · 'DECK CONTINUITY' called out over pier P1”Dimension LF Agent: The crop prints DECK CONTINUITY but does not print a reinforced-concrete material designation for the deck slab.
  • objects · Approach slab — “Approach slab · rectangular slab · reinforced concrete · ×2 · 300 THK. with 150 THK. PCC levelling course beneath” → “Approach slab · rectangular slab · ×2 · 300 THK. with 150 THK. PCC levelling course beneath”Dimension LF Agent: The approach-slab callout prints 300 THK. APPROACH SLAB but does not state its material.
  • objects · Independent retaining wall — “Independent retaining wall · vertical wall · reinforced concrete · ×2 · Called out at both approaches” → “Independent retaining wall · vertical wall · ×2 · Called out at both approaches”Dimension LF Agent: INDEPENDENT RETAINING WALL is printed at both approaches, but no material is printed for those walls.

  • measurements · Pier cap dimension (marked at deck level over pier) — “1500 (SK)” → “1500 (SQ)”Concrete Agent said: The dimension beside the deck-continuity region at P1 is printed "1500 (SQ)."Rejected — The boxed dimension at the P1 deck-continuity region reads "1500 (SK)," not "1500 (SQ)."
  • objects · Bearing pedestal — “Bearing pedestal · rectangular block · reinforced concrete · Shown under bearings; mentioned in cut-off notes list” → “Bearing pedestal · rectangular block · Shown under bearings; mentioned in cut-off notes list”Dimension LF Agent said: The partially visible notes list includes BEARING PEDESTAL, but this crop does not print a material designation for it.Rejected — The visible notes list "BEARING PEDESTAL" under "GRADE OF CONCRETE," so the crop does support identifying the pedestal as concrete.

Universal Validator’s reasoning

I relied on the printed callouts, dimension strings, and the visible grade-of-concrete note only. Changes based on the horizontal elevation dimensions or on missing material callouts are accepted where the crop plainly shows them.

Applied to the reading

  • measurements · Vertical dimension within web (lower portion) — “Vertical dimension within web (lower portion) = 200 — on MID SECTION” → “Bottom flange haunch/taper depth = 200 — on MID SECTION”Concrete Agent: The 200 dimension is drawn between the start of the lower sloping transition and the top of the 250-deep bottom flange; it applies to the lower haunch/taper rather than the straight web.

Universal Validator’s reasoning

The 200 dimension is visibly bracketed over the lower sloping web-to-bottom-flange transition, while no printed quantity/count is shown for either depicted section.

Applied to the reading

  • measurements · Bituminous concrete thickness — “50MM mm” → “50MM”Reinforcement Agent: Note 9 prints the thickness as "50MM"; the current reading duplicates the unit.
  • measurements · Minimum bearing height referenced — “200 mm” → “Bearing-height threshold = 200 mm”Concrete Agent: Note 16 does not state a minimum bearing height; it states a conditional case where the bearing height is less than 200 mm.
  • measurements · Backfill angle of internal friction — “>32° degrees” → “φ>32°”Dimension LF Agent: Note 15 prints the property as "φ>32°". The current reading duplicates the degree unit and omits the printed φ symbol.
  • objects · Abutment & abutment cap — “Abutment & abutment cap · not drawn · concrete M45” → “Abutment & abutment cap · not drawn · abutment concrete M45; abutment-cap concrete grade not stated”Dimension LF Agent: The concrete-grade list in Note 5 assigns M45 to "ABUTMENT & PIER" only. Although Note 6 mentions an abutment cap for clear cover, this crop does not assign it an M45 concrete grade.
  • objects · Pier & pier cap — “Pier & pier cap · not drawn · concrete M45” → “Pier & pier cap · not drawn · pier concrete M45; pier-cap concrete grade not stated”Dimension LF Agent: Note 5 assigns M45 to "ABUTMENT & PIER" only. Note 6 identifies a pier cap only for clear-cover requirements, not for concrete grade.

Proposed and rejected

  • objects · Reinforcement bars — removedReinforcement Agent said: This crop provides only the reinforcing-steel material/grade note and contains no reinforcement detail or separate reinforcing-bar object.Rejected — Note 7 expressly refers to reinforcing steel and deformed (TMT) bars of grade Fe 550D, so the crop does support the Reinforcement bars object.
  • measurements · Minimum bearing height referenced — removedReinforcement Agent said: Note 16 says that if the bearing height is less than 200mm it shall be adjusted in the 200mm pedestal; it does not print 200mm as a minimum bearing height.Rejected — The 200mm value is visibly printed in Note 16 as the comparison point for bearing height; it should be corrected in meaning rather than removed.
  • objects · Abutment & abutment cap — “Abutment & abutment cap · not drawn · concrete M45” → “Abutment · not drawn · concrete M45”Concrete Agent said: Note 5 prints "ABUTMENT & PIER" as M45, while the abutment cap is mentioned only in the clear-cover note and is not assigned an M45 concrete grade in this crop.Rejected — Note 6 explicitly names "ABUTMENT & ABUTMENT CAP" as a component grouping for clear cover. Removing the abutment cap from the object is not supported, even though its concrete grade is not stated.
  • objects · Pier & pier cap — “Pier & pier cap · not drawn · concrete M45” → “Pier · not drawn · concrete M45”Concrete Agent said: Note 5 assigns M45 to the pier, but this crop gives no concrete grade for the pier cap; the pier cap appears only in the clear-cover note.Rejected — Note 6 explicitly names "PIER & PIER CAP" for clear cover. Removing the pier cap from the object is not supported, although Note 5 does not assign it a concrete grade.
  • measurements · Bituminous concrete thickness — “50MM mm” → “50 mm”Concrete Agent said: Note 9 prints "BITUMINOUS CONCRETE 50MM THICK"; the current reading duplicates the unit.Rejected — The crop prints the thickness as "50MM," not "50 mm." The proposed replacement converts the printed form rather than retaining it.
  • measurements · Bituminous concrete thickness — “50MM mm” → “50 mm”Dimension LF Agent said: Note 9 prints "50MM THICK"; the current value repeats the millimetre unit.Rejected — Although the current reading repeats the unit, the crop prints "50MM," so changing it to "50 mm" is an unsupported conversion of the printed value.

Universal Validator’s reasoning

I relied only on the printed notes in this crop, retaining named components where they appear and separating concrete-grade assignments from clear-cover references. Unit duplications are corrected only where the printed value itself supports the exact replacement.

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 Agent3 proposedThe reinforcing-steel note states a material specification only and does not detail reinforcement as a separate object. Note 16 does not state a minimum bearing height; it only gives a conditional case where the bearing height is less than 200mm. · openai/gpt-5.6-terra-pro · 34761 tokens · 48.4s
  • Concrete Agent4 proposedThe concrete-grade list assigns M45 to abutment and pier only; this crop does not assign that grade to the abutment cap or pier cap. The wearing-course thickness is printed as 50MM, not "50MM mm." · openai/gpt-5.6-terra-pro · 27592 tokens · 27.6s
  • Dimension LF Agent4 proposedThe 50MM wearing-course thickness and the backfill friction-angle notation each duplicate their units in the reading. The concrete-grade entries for abutment/pier caps overextend the M45 attribution beyond the components named in the grade list. · openai/gpt-5.6-terra-pro · 33889 tokens · 43.3s

Applied to the reading

  • measurements · Bituminous concrete thickness — “50MM mm” → “50MM”Reinforcement Agent: Note 9 prints the thickness as "50MM"; the current value repeats the millimetre unit.
  • measurements · Backfill angle of internal friction — “⌀>32° degrees” → “⌀>32°”Reinforcement Agent: Note 15 prints the property as "⌀>32°"; the current value adds a duplicate written angle unit.
  • objects · Bearing — “Bearing · 400mm depth of brg. & pedestal assumed; minimum bearing height 200mm referenced” → “Bearing · 400mm depth of brg. & pedestal considered; bearing height less than 200mm referenced”Reinforcement Agent: Note 16 says the piercap level considers 400mm depth of bearing and pedestal and gives a condition for bearing height less than 200mm; it does not label 200mm as a minimum bearing height.
  • measurements · Minimum bearing height referenced — removedReinforcement Agent: Note 16 does not state a minimum bearing height; it only states the condition "in case the bearing height is less than that of 200mm."
  • measurements · Bituminous concrete thickness — “50MM mm” → “50MM”Dimension LF Agent: Note 9 in this crop states "BITUMINOUS CONCRETE 50MM THICK LAID IN SINGLE LAYER"; the reading repeats the millimetre unit.

Proposed and rejected

  • objects · [Fe 550D] Reinforcement bar — removedReinforcement Agent said: Note 7 specifies the grade and type of reinforcing steel generally, but this crop contains no reinforcement bar detail, bar mark, size, count, or schedule.Rejected — Note 7 visibly specifies “ALL REINFORCING STEEL” as high-yield-strength deformed (TMT) bars of grade Fe 550D, so the reinforcement-bar object is supported by this notes crop.
  • measurements · Reinforcing steel grade — removedReinforcement Agent said: This measurement is attached to a separate reinforcement-bar object that is not detailed in this crop; Note 7 is only a general material specification.Rejected — Note 7 visibly prints the reinforcing-steel grade as Fe 550D; the grade measurement is supported by the crop even though no bar schedule is shown.
  • measurements · Bituminous concrete thickness — “50MM mm” → “50 mm”Concrete Agent said: Note 9 states “BITUMINOUS CONCRETE 50MM THICK”; the current value repeats the millimetre unit.Rejected — Although the existing entry duplicates a unit, Note 9 prints the value as “50MM.” The proposed “50 mm” changes the printed form rather than retaining the visible value.

Universal Validator’s reasoning

The notes explicitly specify reinforcing-steel bars and their Fe 550D grade, so those entries remain supported despite the lack of bar detailing. Corrections are accepted where the current reading adds wording or units not printed in the crop, or misstates Note 16's 200mm condition.

Applied to the reading

  • objects · A2 — “reinforced concrete” → “material not stated”Concrete Agent: No concrete or RCC material label is printed for the abutment in this crop; the only RCC label points to the seismic stopper.
  • objects · Deck slab / box girder superstructure — “reinforced concrete” → “material not stated”Concrete Agent: The shown box-girder/deck section has dimensions but no printed concrete or RCC material designation.
  • objects · Pile cap — “reinforced concrete” → “material not stated”Concrete Agent: The dashed pile-cap outline is shown without a concrete or RCC material label in this crop.
  • objects · Bored cast-in-situ pile — “reinforced concrete (cast-in-situ)” → “cast-in-situ; material not stated”Concrete Agent: The callout prints "1200 DIA BORED CAST-IN-SITU PILES" but does not print concrete or RCC as their material.
  • objects · Approach slab — “reinforced concrete” → “material not stated”Concrete Agent: No concrete or RCC material designation is printed for the sloping slab at the left of the section.
  • objects · Bearing pedestal — “reinforced concrete” → “material not stated”Concrete Agent: The crop shows the pedestal below the bearing but does not print a concrete or RCC material designation for it.
  • measurements · Distance from grid/centre of bearing (square) — “1070 (SQ.) — on A2 abutment / C of BRG.” → “1070 (SQ.) — between C OF BRG. and C OF EXP.

  • measurements · Distance (skew) — “1236 (SK.) — on A2 abutment / C of BRG.” → “1236 (SK.) — between C OF BRG. and C OF EXP. JOINT”Dimension LF Agent: The stacked skew dimension shares the same two centre-line references shown for the 1070 (SQ.) dimension.

Proposed and rejected

  • objects · Bored cast-in-situ pile — “reinforced concrete (cast-in-situ)” → “cast-in-situ”Dimension LF Agent said: The callout prints "1200 DIA BORED CAST-IN-SITU PILES" but does not state reinforced concrete.Rejected — Although "CAST-IN-SITU" is printed in the pile callout, it is a construction description rather than a stated material; change 4 correctly retains that description while recording that the material is not stated.

Universal Validator’s reasoning

The crop contains no material labels for the abutment, deck, pile cap, approach slab, bearing pedestal, or piles; the only printed RCC designation is for the seismic stopper. The 1070 and 1236 dimensions are visibly drawn between the centre lines marked C OF BRG. and C OF EXP. JOINT.

Applied to the reading

  • objects · Pier — “reinforced concrete (implied by notes; not stated in this view)” → “concrete”Concrete Agent: The crop’s concrete-grade note includes “ABUTMENT & PIER,” but no callout or section note assigns reinforcement to the pier itself.

Proposed and rejected

The visible note heading concerns concrete grades, but no material designation is printed on this pier section.Rejected — Removing the material entirely is not supported: the visible concrete-grade note expressly includes “ABUTMENT & PIER,” so the crop does attribute concrete to the pier.

Universal Validator’s reasoning

The visible general note is headed “GRADE OF CONCRETE” and expressly lists “ABUTMENT & PIER,” supporting concrete as the pier material. Nothing visible attributes reinforcement to this section.

What each agent cost

  • Concrete Agent0 proposedThe crop explicitly identifies RCC crash barrier, RCC seismic stopper, RCC column pier, and RCC pilecap, but it does not print a concrete material designation for the deck slab, pier cap, or bored cast-in-situ piles. Their recorded reinforced-concrete materials are therefore unsupported by this crop. · openai/gpt-5.6-terra-pro · 20916 tokens · 29.4s
  • Dimension LF Agent2 proposedThe two 750 dimensions at the pilecap are from the pilecap outer edges to the pile centrelines, as shown by the 750–3600–750 chain totaling the 5100 overall width; they are not edge-to-edge pile distances. · openai/gpt-5.6-terra-pro · 26313 tokens · 49.7s

  • objects · Pier cap — “reinforced concrete” → “not stated”Concrete Agent: The cap is dimensioned in the section, but no RCC or concrete material label is printed against the pier cap in this crop.
  • objects · Bored cast-in-situ pile — “reinforced concrete (cast-in-situ)” → “not stated”Concrete Agent: The printed callout is "1200 DIA BORED CAST-IN-SITU PILES"; it does not state reinforced concrete as the pile material.
  • measurements · Partial dimension at right edge of crop (cut off) — removedDimension LF Agent: Only a partial rotated "25" fragment and part of its dimension line are visible at the right crop edge; the complete printed dimension is cut off.

Universal Validator’s reasoning

Material changes are accepted only where the relevant material is not printed against that object in this crop. The right-edge value is visibly truncated, so it cannot be retained as a measurement.

Proposed and rejected

  • objects · Pier / column section — “Pier / column section (concrete member cross section at pier location) · rectangular with chamfered corners · ×1 · Outline only; no reinforcement or hatching shown in this crop. Material not stated on the crop.” → “Pier / column section at pier location · rectangular with chamfered corners · ×1 · Outline only; no reinforcement or hatching shown in this crop. Material not stated on the crop.”Concrete Agent said: The title reads "SECTION AT PIER LOCATION," but this crop contains no printed concrete material note or designation.Rejected — Although "at pier location" is supported by the title, the crop does not identify the depicted member itself as a pier or column. Retaining "Pier / column section" adds an unsupported object designation.

Universal Validator’s reasoning

The crop explicitly titles the view "SECTION AT PIER LOCATION" but does not identify the outlined member as a pier, column, or concrete. The supported correction is therefore the one that uses the printed view title without adding an unprinted member designation.

  • objects · Footpath — “Footpath (raised walkway on deck) · rectangular · reinforced concrete (implied) · ×2 · Labelled FOOTPATH, 1500 wide, at outer edge of each carriageway” → “Footpath (raised walkway on deck) · rectangular · ×2 · Labelled FOOTPATH, 1500 wide, at outer edge of each carriageway”Reinforcement Agent: The crop labels FOOTPATH and dimensions it 1500, but does not print a concrete or reinforcement material designation for the footpaths.
  • objects · Girder / deck web — “Girder / deck web · vertical web (I/T type as drawn) · reinforced concrete (implied) · ×10 · 5 per deck at 3500 spacing with 1275 overhang each side; type not annotated in this crop” → “Girder / deck web · vertical web (I/T type as drawn) · ×10 · 5 per deck at 3500 spacing with 1275 overhang each side; type not annotated in this crop”Reinforcement Agent: The crop prints "RCC CAST IN SITU DECK" but does not separately designate the depicted webs/girders as reinforced concrete.
  • objects · Bearing / pedestal block (hatched) — “Bearing / pedestal block (hatched) · small rectangular hatched block · not stated · ×4 · Hatched blocks at outer soffit ends of each deck; identity not labelled — reading uncertain” → “Bearing / pedestal block (hatched) · small rectangular hatched block · not stated · ×2 · Hatched blocks at the median-side soffit end of each deck; identity not labelled”Reinforcement Agent: Only two shaded rectangular blocks are visible: one at the median-side end of each deck. The outer soffit ends do not show corresponding shaded blocks.
  • objects · Abutment wall / stem — “[A1 & A2 (per title)] Abutment wall / stem · rectangular wall in elevation, 1000 thick · reinforced concrete (implied) · ×2 · Shown behind/below each deck with dotted (reinforcement or pile-behind) pattern; 1000 dimension marked at both faces” → “[A1 & A2 (per title)] Abutment wall / stem · rectangular wall in elevation, 1000 thick · ×2 · Shown behind/below each deck with dotted pattern; 1000 dimension marked at both faces”Reinforcement Agent: No RCC or reinforcement material designation is printed for the abutment walls in this crop.
  • objects · Pile cap — “Pile cap · rectangular · reinforced concrete (implied) · ×2 · 16550 long each; pile top level (PCTL) and pile cap bottom level (PCBL) noted at both L/S and R/S” → “Pile cap · rectangular · ×2 · 16550 long each; pile top level (PCTL) and pile cap bottom level (PCBL) noted at both L/S and R/S”Reinforcement Agent: The crop prints pile-cap dimensions and levels but does not state a reinforced-concrete material for the pile caps.
  • objects · Pile — “Pile · circular (drawn dashed within pile cap) · reinforced concrete (implied) · ×10 · 5 per pile cap at 3750 c/c with 775 end offsets; pile tip levels annotated” → “Pile · outline shown below pile cap · ×10 · 5 per pile cap at 3750 c/c with 775 end offsets; pile tip levels annotated”Reinforcement Agent: The crop shows five pile outlines below each pile cap, but does not identify their section as circular or state their material.
  • objects · Cantilever median wall — “Cantilever median wall · vertical hatched wall between the two decks · reinforced concrete (implied) · ×1 · Labelled 'CANTILEVER MEDIAN WALL'” → “Cantilever median wall · vertical hatched wall between the two decks · ×1 · Labelled 'CANTILEVER MEDIAN WALL'”Reinforcement Agent: The crop labels the feature "CANTILEVER MEDIAN WALL" but does not print an RCC or reinforced-concrete material designation for it.
  • objects · Expansion/longitudinal gap between decks — “Expansion/longitudinal gap between decks · 20mm vertical gap · polysulphide sealant filling · ×1 · See note” → “Deck-to-deck gap · 20mm gap · polysulphide sealant filling · ×1 · Printed note: "20mm GAP FILLED WITH POLYSULPHIDE SEALANT"”Reinforcement Agent: The printed note identifies a 20mm sealed gap, but does not call it an expansion joint or longitudinal gap.
  • objects · Embankment / side slope with pitching or vegetation symbols — “Embankment / side slope with pitching or vegetation symbols · sloping 1:2 (marked 2 horizontal : 1 vertical) · earth fill · ×2 · Slope hatch lines fan out from each deck edge to natural ground line” → “Embankment / side slope with pitching or vegetation symbols · sloping 1:2 (marked 2 horizontal : 1 vertical) · ×2 · Slope hatch lines fan out from each deck edge to natural ground line”Reinforcement Agent: The slope geometry is drawn, but no earth-fill material is printed in this crop.
  • measurements · Wearing course thickness — “50mm mm” → “50mm”Reinforcement Agent: The callout prints "50mm THK. (WC)"; the reading duplicates the unit.
  • measurements · Deck crossfall — “2.5% %” → “2.5%”Reinforcement Agent: The callouts print "SLOPE 2.5%"; the reading duplicates the percent sign.
  • measurements · Dimension within deck depth — “750 — on Deck slab / web zone (shown once per deck)” → “750 — horizontal dimension in deck/web zone (shown once per deck)”Reinforcement Agent: The two 750 dimensions are drawn horizontally in the web/deck zone, not as vertical deck-depth dimensions.
  • measurements · Gap width filled with sealant — “20mm mm” → “20mm”Reinforcement Agent: The printed note states "20mm GAP FILLED WITH POLYSULPHIDE SEALANT"; the reading duplicates the unit.
  • objects · Footpath — “reinforced concrete (implied)” → “not stated”Concrete Agent: The FOOTPATH label and its 1500 dimension are visible, but no concrete or RCC material designation is printed for the footpath in this crop.
  • objects · Girder / deck web — “reinforced concrete (implied)” → “not stated”Concrete Agent: The crop shows the web/rib geometry and 3500 spacing, but does not print a concrete or RCC material designation specifically for these members.
  • objects · Abutment wall / stem — “reinforced concrete (implied)” → “not stated”Concrete Agent: The abutment wall/stem is drawn and dimensioned, but this crop does not print an RCC or concrete material label for it.
  • objects · Pile cap — “reinforced concrete (implied)” → “not stated”Concrete Agent: The pile cap is shown with dimensions and level callouts, but no concrete or RCC material designation is printed for it in the crop.

  • objects · Cantilever median wall — “reinforced concrete (implied)” → “not stated”Concrete Agent: The crop labels this member CANTILEVER MEDIAN WALL, but does not print RCC or another concrete material designation for it.
  • measurements · Wearing course thickness — “50mm mm” → “50mm”Concrete Agent: The callout on each deck reads "50mm THK. (WC)"; only one mm unit is printed.
  • objects · Footpath (raised walkway on deck) — “reinforced concrete (implied)” → “material not stated”Dimension LF Agent: The crop labels the feature FOOTPATH and shows its 1500 dimension, but does not print a concrete material designation for it.
  • objects · Girder / deck web — “reinforced concrete (implied)” → “material not stated”Dimension LF Agent: The vertical members are drawn and dimensioned, but no material designation is printed for them in this crop.
  • objects · [A1 & A2 (per title)] Abutment wall / stem — “rectangular wall in elevation, 1000 thick · reinforced concrete (implied)” → “rectangular wall in elevation · material not stated”Dimension LF Agent: No reinforced-concrete material is printed for this wall, and the 1000 callouts are vertical dimensions in the section rather than a horizontal wall-thickness dimension.
  • objects · Pile cap — “reinforced concrete (implied)” → “material not stated”Dimension LF Agent: The pile caps are drawn and dimensioned, but the crop does not print a reinforced-concrete material designation for them.
  • objects · Pile — “reinforced concrete (implied)” → “material not stated”Dimension LF Agent: The piles are drawn and spaced, but their material is not labelled in this crop.
  • objects · Cantilever median wall — “reinforced concrete (implied)” → “material not stated”Dimension LF Agent: The crop prints CANTILEVER MEDIAN WALL but does not print an RCC or other material designation for that wall.
  • objects · Embankment / side slope with pitching or vegetation symbols — “earth fill” → “material not stated”Dimension LF Agent: The side slopes and slope-ratio marks are drawn, but the crop does not identify the embankment material as earth fill.
  • measurements · Kerb / edge upstand thickness — “Kerb / edge upstand thickness = 100 — on Deck edge (shown 4 times)” → “Deck-edge horizontal dimension = 100 — on Deck edge (shown 4 times)”Dimension LF Agent: The four 100 callouts are horizontal dimensions at the deck edges; no kerb or edge-upstand label is printed in the crop.
  • measurements · Wearing course thickness — “50mm mm” → “50mm”Dimension LF Agent: The printed callout is "50mm THK. (WC)"; the reading duplicates the mm unit.
  • measurements · Dimension within deck depth — “Dimension within deck depth = 750 — on Deck slab / web zone (shown once per deck)” → “Girder / deck web width = 750 — on Girder / deck web (shown once per deck)”Dimension LF Agent: Each 750 dimension is drawn horizontally across a web/member width beneath the deck, not vertically through the deck depth.
  • measurements · Abutment wall thickness — “Abutment wall thickness = 1000 — on Abutment wall (shown at four locations)” → “Abutment wall vertical dimension = 1000 — on Abutment wall (shown at four locations)”Dimension LF Agent: The 1000 callouts are vertically oriented between their extension lines at the abutment-wall locations, so this crop does not support reading them as wall thicknesses.
  • measurements · Gap width filled with sealant — “20mm mm” → “20mm”Dimension LF Agent: The printed note reads "20mm GAP FILLED WITH POLYSULPHIDE SEALANT"; the reading duplicates the mm unit.

Universal Validator’s reasoning

I relied only on labels, callouts, dimensions, and feature locations visible in the crop. The crop supports removal of unprinted material/type inferences and correction of duplicated units or misdescribed dimension orientations.

What each agent cost

  • Reinforcement Agent13 proposedSeveral object descriptions assign materials or pile geometry not printed in this crop, and the shaded soffit blocks are only two, at the median-side ends of the decks. The 750 dimension is horizontal in the deck/web zone rather than a deck-depth dimension; duplicate units have also been removed from printed callouts. · openai/gpt-5.6-terra-pro · 39496 tokens · 75.3s
  • Concrete Agent7 proposedThe crop explicitly identifies only the crash barriers and cast-in-situ decks as RCC, and the PCC M-15 layer as concrete. The other listed members are not given a concrete material label in this crop; the wearing-course callout prints 50mm, not 50mm mm. · openai/gpt-5.6-terra-pro · 27517 tokens · 41.8s
  • Dimension LF Agent12 proposedThe 750 and 1000 dimensions are drawn horizontally and vertically, respectively, so they should not be called deck depth or wall thickness. Several objects are identified graphically but their reinforced-concrete or earth-fill materials are not printed in this crop. · openai/gpt-5.6-terra-pro · 38518 tokens · 85.5s

  • measurements · Wearing coat thickness — “50mm mm” → “50mm”Dimension LF Agent: The deck note in this crop reads “50mm THK. (WC)”; the reading repeats the mm unit.
  • measurements · Median gap filled with sealant — “20mm mm” → “20mm”Dimension LF Agent: The median note reads “20mm GAP FILLED WITH POLYSULPHIDE SEALANT”; the reading repeats the mm unit.
  • objects · Footpath — “reinforced concrete (implied)” → “material not stated in crop”Dimension LF Agent: The crop labels the feature “FOOTPATH” and dimensions it, but does not print a reinforced-concrete material designation for it.
  • objects · Girder / deck stem — “concrete (not explicitly stated)” → “material not stated in crop”Dimension LF Agent: The five supporting lines per carriageway are drawn, but this crop contains no concrete material label or girder type annotation for them.
  • objects · Abutment (cantilever wall type) with abutment cap — “reinforced concrete” → “abutment wall/cap; material and wall type not stated in crop”Dimension LF Agent: The section title and ACTL callouts support an abutment location, but the crop does not label these wall/cap elements as reinforced concrete or as a cantilever-wall type.
  • objects · Cantilever median wall — “reinforced concrete” → “material not stated in crop”Dimension LF Agent: “CANTILEVER MEDIAN WALL” is printed, but no reinforced-concrete material designation is printed for that wall in this crop.
  • objects · Pile cap — “reinforced concrete” → “material not stated in crop”Dimension LF Agent: The pile caps and their dimensions/levels are drawn, but no reinforced-concrete material designation is printed for them.
  • objects · Pile — “reinforced concrete (implied)” → “material not stated in crop”Dimension LF Agent: The pile shafts and pile-tip-level callouts are drawn, but the crop does not state that the piles are reinforced concrete.
  • objects · Stone pitching / rock protection — “stone / boulders” → “irregular protection pattern; material not stated in crop”Dimension LF Agent: An irregular pattern is drawn on each side slope, but this crop contains no text identifying it as stone, rock, or boulders.

Proposed and rejected

  • objects · Embankment / side slope — “slope 1 : 2 (V:H as marked 2 / 1) · earth fill” → “slope 2 : 1 as drawn, with 2 horizontal to 1 vertical; material not stated in crop”Dimension LF Agent said: The slope triangle shows 2 in the horizontal direction and 1 vertically. No earth-fill material label is printed in this crop.Rejected — The slope triangle visibly marks 2 horizontally and 1 vertically, which supports the existing V:H reading of 1:2. Recasting it as 2:1 changes the printed directional expression rather than transcribing it; the unsupported earth-fill material should not cause acceptance of that converted slope change.

Universal Validator’s reasoning

The crop supports removing material designations where no material callout is printed, and it confirms the printed 50mm and 20mm values without duplicated units. The slope graphic shows 2 horizontally and 1 vertically, but does not print a ratio convention that warrants replacing the existing V:H expression with a converted ratio.

What each agent cost

  • Concrete Agent8 proposedThe crop explicitly identifies only the crash barriers and cast-in-situ decks as RCC, and identifies the levelling course as PCC M-15; it does not print concrete material designations for the footpaths, girders, abutments, median wall, pile caps, or piles. The two measurements also duplicate the printed mm unit. · openai/gpt-5.6-terra-pro · 26351 tokens · 32.3s
  • Dimension LF Agent10 proposedThe dimensional readings and levels are supported by the crop, except that the two metric thickness/gap values duplicate the printed “mm” unit. Several object material/type descriptions are inferred rather than printed in this crop and should not be carried into a quantity reading. · openai/gpt-5.6-terra-pro · 32689 tokens · 53.0s

Applied to the reading

  • objects · Wearing coat — “bituminous/concrete wearing course (50mm THK. WC)” → “wearing coat (50mm THK. (WC)); material not stated”Concrete Agent: The crop prints only "50mm THK. (WC)" for this layer; it does not identify it as bituminous or concrete.
  • objects · Footpath — “reinforced concrete (implied)” → “material not stated”Concrete Agent: The crop labels the feature "FOOTPATH" and dimensions it, but contains no RCC or concrete material callout for it.
  • objects · Pier cap — “reinforced concrete” → “material not stated”Concrete Agent: Although the member is shown as a pier cap, no concrete or RCC material label is printed against the pier caps in this crop.
  • objects · Pier column — “reinforced concrete” → “material not stated”Concrete Agent: The columns are drawn and dimensioned, but this crop provides no concrete or RCC material callout for them.
  • objects · [P1] Pile cap — “reinforced concrete” → “material not stated”Concrete Agent: The crop prints pile-cap levels and dimensions but no concrete or RCC material designation for the pile caps.
  • objects · [P1] Pile — “reinforced concrete” → “material not stated”Concrete Agent: The piles and their tip levels are shown, but no concrete or RCC material designation is printed for the piles.
  • measurements · Wearing coat thickness — “50mm THK. (WC) mm” → “50mm THK. (WC)”Concrete Agent: The printed callout reads "50mm THK. (WC)"; the reading adds a second "mm" after the printed text.
  • objects · Wearing coat — “Wearing coat · thin overlay on deck · bituminous/concrete wearing course (50mm THK. WC) · ×2 · Shown on each deck with 2.5% slope” → “Wearing coat · thin overlay on deck · 50mm THK. (WC) · ×2 · Shown on each deck with 2.5% slope”Dimension LF Agent: The crop identifies the layer only as "50mm THK. (WC)"; it does not state bituminous or concrete material.
  • objects · Footpath — “Footpath · raised rectangular kerb/walkway · reinforced concrete (implied) · ×2 · Labelled 'FOOTPATH', 1500 wide” → “Footpath · raised rectangular kerb/walkway · ×2 · Labelled 'FOOTPATH', 1500 wide”Dimension LF Agent: The crop labels these elements "FOOTPATH" but does not print a reinforced-concrete material designation for them.
  • objects · Pier cap — “Pier cap · trapezoidal (tapered ends) · reinforced concrete · ×2 · One cap per carriageway, 16550 long, level marked PCTL” → “Pier cap · trapezoidal (tapered ends) · ×2 · One cap per carriageway, 16550 long, level marked PCTL”Dimension LF Agent: No reinforced-concrete material callout is printed against the pier caps in this crop.
  • objects · Pier column — “Pier column · circular/vertical shaft as drawn · reinforced concrete · ×6 · 3 columns visible under each pier cap (spacing 4500 with 1000 offsets)” → “Pier column · circular/vertical shaft as drawn · ×6 · 3 columns visible under each pier cap (spacing 4500 with 1000 offsets)”Dimension LF Agent: The crop shows the columns but does not print a reinforced-concrete material designation for them.
  • objects · [P1] Pile cap — “[P1] Pile cap · rectangular · reinforced concrete · ×2 · 16550 long; top level PCTL P1 503.316, bottom level PCBL P1 501.516” → “[P1] Pile cap · rectangular · ×2 · 16550 long; top level PCTL P1 503.316, bottom level PCBL P1 501.516”Dimension LF Agent: The PCTL/PCBL and 16550 annotations are shown, but no reinforced-concrete material is printed for the pile caps.

  • measurements · Wearing coat thickness — “50mm THK. (WC) mm — on wearing coat” → “50mm THK. (WC) — on wearing coat”Dimension LF Agent: The callout over each deck reads "50mm THK. (WC)"; the additional trailing "mm" is not printed.
  • measurements · Bearing/girder spacing (square) — “3500 (SQ) — on pier cap top - 5 spaces each side” → “3500 (SQ) — on pier cap top - 4 spaces each side”Dimension LF Agent: Each pier-cap dimension chain has four intervals labelled 3500 (SQ), bounded by 1275 (SQ) end dimensions.
  • measurements · Column end offset — “1000 — on pier column to cap end (3 per side)” → “1000 — on pier column to cap end (2 per side)”Dimension LF Agent: For each carriageway, the column dimension chain shows one 1000 offset at each cap end, with two 4500 intervals between the three columns.

Universal Validator’s reasoning

The crop explicitly labels RCC only for the cast-in-situ deck and crash barriers; it provides no material callouts for the wearing coat, footpaths, substructure, or piles. The dimension chains visibly show four 3500 intervals per pier cap and two 1000 end offsets per three-column arrangement.

What each agent cost

  • Concrete Agent7 proposedOnly the deck slab and crash barrier are identified as RCC in this crop. The footpaths, pier caps, pier columns, pile caps and piles have no printed concrete-material designation, and the wearing-coat label does not state its material. · openai/gpt-5.6-terra-pro · 23630 tokens · 45.7s
  • Dimension LF Agent9 proposedThe crop shows four 3500 (SQ) intervals and two 1000 end offsets per carriageway, not five and three respectively. It also prints no material designation for the footpaths, pier caps, columns, pile caps, or piles, and the wearing-coat callout is exactly "50mm THK.

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.

77% of items placed. The 10 below fit no class — add one to the ontology and match again.

◈Index for the agentnot indexed · 1353 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.
