Quantara vs RIB CostX: BOQ and Takeoff Comparison
Choose RIB CostX when established 2D/3D measurement, BIM quantities and integrated estimating workbooks are the central need. Choose Quantara when a simpler SaaS journey should turn supported drawing evidence into a structured unpriced BOQ with assumptions, review and client deliverables.
Project information, extracted data, measurements, calculations, rates and outputs require review by the responsible construction professional before tender, procurement, contractual or construction use.
Choose RIB CostX when
- • Detailed 2D drawing and 3D/BIM measurement.
- • Experienced estimators working with integrated estimating workbooks.
- • Teams that require drawing revision comparison and mature takeoff controls.
Choose Quantara when
- • Your starting point is an industry selection and a complete drawing set.
- • You need a structured, quantity-complete unpriced BOQ rather than only drawing markups.
- • Every quantity should carry calculation evidence, drawing provenance, assumptions and unresolved evidence for review.
- • Your team wants to add its own rates, govern revisions, lock reviewed work and produce client-facing documents.
