Product
MEP takeoff that proves every quantity
TeraQuant connects Peak-style PDF drawings to Schedule of Rates lines, extracts MEP symbols with vision AI, and reconciles AI quantities against Peak-SOR ground truth on Schedule C—with evidence pinned to the drawing.
- Input
- PDF + SOR xlsx
- Evidence

Capabilities
Built for verification-first MEP takeoff
From drawing upload to Schedule C reconciliation—one workflow that keeps quantities, evidence, and SOR lines connected.
PDF + SOR takeoff
Upload Peak-style PDF drawings and Schedule of Rates workbooks. Map each drawing to the right discipline sheet—P&D, FS, MVAC, or EL&ELV—and run takeoff against the real tender structure.
Evidence-linked overlays
Every claim pins back to the drawing. CAD-like PDF viewing with page-scoped evidence boxes, polylines, and audit-ready locations so quantity review stays grounded in the source.
AI vision extraction
Vision models read MEP symbols, labels, and counts from plan sheets. Extraction writes structured claims with confidence and evidence links—not free-text guesses.
Schedule C vs Peak-SOR
Compare AI quantities to Peak-SOR ground truth on Schedule C. See match, miss, and variance per line so tender verification is measurable, not subjective.
Workflow
From PDF to verified quantities
A linear takeoff path designed for QS review: ingest, extract, evidence, then Schedule C comparison.
- 01
Ingest drawings & SOR
Load PDF plan sheets and Peak-SOR xlsx. Discipline inference routes each file to the correct Schedule of Rates sheet.
- 02
Extract with vision
Run page extract or legend takeoff. AI locates MEP symbols and quantities; geometric takeoff measures pipe runs in metres.
- 03
Link evidence on CAD
Claims overlay the PDF in display coordinates. Select a line to pin evidence, review bboxes, and keep page-scoped audit trails.
- 04
Reconcile Schedule C
Side-by-side AI qty vs Peak-SOR ground truth. Close the loop on tender quantities with match stats per SOR line.
Drawing workspace
CAD-grade PDF viewing with claim overlays
Page-scoped evidence, selected claim pins, and Schedule C side panel—so takeoff never drifts from the drawing.
