Revision control
Measure against a known source revision and preserve that source.
Quantity Takeoff
Quantity takeoff that feeds the real commercial workflow.
Measure drawings and model outputs into reviewable construction quantities that can continue into BOQ, estimating, tender and change control.
Direct answer
What is quantity takeoff?
Quantity takeoff is the measurement of construction work from drawings, models or other design information to determine counts, lengths, areas, volumes and related quantities. CivilQuant keeps the measurement formula, source revision, deductions and reviewer decision attached to the resulting quantity.
What CivilQuant delivers
Measurement with context, not just coloured marks
CivilQuant can support manual calibrated takeoff and automated or semantic measurement workflows, depending on the drawing and project setup.
Calibrated takeoff
Use drawing dimensions and calibration for line, area and polygon measurement.
Semantic quantities
Represent measured construction elements and their relationships.
Formula evidence
Preserve gross, deduction, net and unit-aware calculation logic.
Duplicate control
Detect or review overlapping candidate quantities and repeated elements.
Reviewer approval
Accept, reject or escalate quantities before commercial issue.
Evidence-backed delivery
A takeoff should survive the next drawing revision
CivilQuant is designed to make changes reviewable and to keep measurements connected to downstream cost records.
- Source revision linked to each measurement
- Known-dimension calibration for manual takeoff
- Explicit deductions and boundary assumptions
- Semantic element relationships where available
- Exception handling for ambiguous geometry
- Continuity into BOQ and variation workflows

Platform + service
Professional work backed by a quantitative intelligence platform
The CivilQuant platform connects documents, quantities, formulas, rates, approvals and evidence so that service delivery can be faster without losing traceability.
Evidence Graph
Connect source documents, revisions, assumptions and outputs.
Deterministic engines
Use decimal-safe, unit-aware calculations for authoritative commercial arithmetic.
Human authorization
Keep professional judgement and issued decisions behind explicit review gates.
Frequently asked questions
Questions about quantity takeoff services
Can CivilQuant measure PDF drawings? +
Yes. Manual calibrated takeoff can use known dimensions from a PDF drawing, while semantic or automated workflows can be used where the document and project configuration support them.
Can it measure areas and volumes? +
Yes. CivilQuant includes formula-backed measurement for counts, lengths, areas, volumes and construction assemblies, with reviewer control.
What if the drawing scale is unreliable? +
The measurement should be calibrated from known dimensions or the issue should be treated as an evidence exception rather than assuming a printed scale.
Can takeoff quantities feed a BOQ? +
Yes. That continuity is a core CivilQuant design goal: approved measurement evidence can flow into BOQ and commercial records.
