Schema v1.0

ProjMgtAI Data Schema

Every extraction produces structured JSON output following this schema. Designed for machine readability, AI agent consumption, and integration into construction workflows.

Scope Object

Each extracted millwork item is a Scope Object. One object per item — cabinet sections, countertops, panels, hardware, and scope exclusions each get their own row.

idstring

Unique item identifier within the extraction

e.g. 001

roomstring

Room or assembly name as detected from drawings

e.g. Reception Desk

item_typeenum

Millwork category. One of: assembly, base_cabinet, upper_cabinet, tall_cabinet, countertop, transaction_top, decorative_panel, trim, channel, rubber_base, substrate, concealed_hinge, piano_hinge, grommet, adjustable_shelf, fixed_shelf, cpu_shelf, drawer, file_drawer, trash_drawer, rollout_basket, conduit, j_box, equipment_cutout, safe_cabinet, controls_cabinet, end_panel, corner_guard, trellis, ada_fascia, wall_cap, scope_exclusion

e.g. base_cabinet

descriptionstring

Plain text description of the item

e.g. Base Cabinet Section 18A

section_idstring

Drawing callout or section identifier

e.g. 18A

qtynumber

Quantity of this item

e.g. 4

unitenum

Unit of measure: EA, LF, SF, LOT

e.g. EA

dimensions.width_mmnumber

Face width in millimeters (run length along wall)

e.g. 1359

dimensions.depth_mmnumber

Front-to-back depth in millimeters

e.g. 610

dimensions.height_mmnumber

Vertical height in millimeters

e.g. 864

dimensions.dim_sourceenum

How dimensions were obtained: extracted (from drawing text), calculated (derived), unknown

e.g. extracted

material_codestring

Material code from project legend

e.g. PL-01

materialstring

Full material description

e.g. Plastic Laminate

sheet_refstring

Drawing sheet and detail reference

e.g. 1/A8.10

confidenceenum

Extraction confidence: high (type+dims+material), medium (missing one), low (missing two or more)

e.g. high

rulestring

Classification rule applied

e.g. RULE_cabinet_with_dims

{
  "id": "002",
  "room": "Reception Desk",
  "item_type": "base_cabinet",
  "description": "Base Cabinet Section 18A",
  "section_id": "18A",
  "qty": 1,
  "unit": "EA",
  "dimensions": {
    "width_mm": 1359,
    "depth_mm": 610,
    "height_mm": 864,
    "dim_source": "extracted"
  },
  "material_code": "PL-01",
  "material": "Plastic Laminate",
  "sheet_ref": "1/A8.10",
  "confidence": "high",
  "rule": "RULE_cabinet_with_dims"
}

RFI Object

Every scope gap, missing dimension, undefined material, or ambiguous exclusion generates an RFI Object. These are pre-bid RFIs — gaps caught before the job starts.

rfi_idstring

Sequential RFI identifier

e.g. RFI-001

priorityenum

High / Medium / Low / Info

e.g. High

categoryenum

Missing Scope / Scope Exclusion / Missing Dimensions / Missing Material / Sheet Reference / Extraction Note

e.g. Missing Scope

roomstring

Room or area where the gap was identified

e.g. Service Manager

descriptionstring

Plain text description of the gap and recommended action

e.g. Upper cabinets not found. Verify scope on interior elevation sheet.

sheet_refstring

Drawing reference where the gap was identified

e.g. A8.02

statusenum

Open / Resolved

e.g. Open

{
  "rfi_id": "RFI-002",
  "priority": "Medium",
  "category": "Missing Dimensions",
  "room": "Vanity Details",
  "description": "19 vanity sections without width dimensions. Section IDs: 101A, 101B, 101C...",
  "sheet_ref": "A8.06",
  "status": "Open"
}

Confidence Score

Every Scope Object carries a confidence score based on the evidence available at extraction time.

high

Item type + dimensions + material all present

medium

One of: type, dimensions, or material missing

low

Two or more of: type, dimensions, material missing

Item Type Reference

All valid item_type values in the ProjMgtAI schema.
