BIM Quantity Intelligence

Quantity data
that lives in the model

Upload IFC or Revit. Every quantity stays linked to its source element — so a take-off is never a dead spreadsheet again.

The problem

The model exists.
The take-off doesn't.

Teams spend 50–80% of estimation time on quantification alone. And the moment you export to a spreadsheet, the link to the model breaks — every design revision means re-doing the count by hand.

Design revision 4 → take-off revision 4. Manually. Again.

Inspect

Click an element.
Read its quantities.

Select anything in the model and Qoloris decomposes it — concrete grade, rebar tonnage, formwork area — down to the assembly. Compound elements are broken out automatically, with full classification coverage.

Compare

Design changed?
Know exactly what.

Load two versions and Qoloris shows the quantity delta element-by-element: what was added, modified, or removed — and by how much. No more diffing spreadsheets line by line.

Validate

Catch anomalies
before they cost you.

Qoloris flags outliers automatically — a beam run 312% above grid average, a mis-modelled wall, a duplicated slab. Find the modelling errors before they hit the tender price.

Deliver

Export without
losing the context.

Push to Excel, CostX or CSV. Every row carries its source element IDs and classification — so the next person can trace any number straight back to the model.

Built for your role

One model. Every stakeholder's question, answered.

Quantity Surveyor
I need a BOQ from this IFC in 3 days for a tender.
Classified take-off in hours, not days — export straight to your costing tool.
Cost Engineer
Which line items moved since the last cost plan?
Version delta shows every quantity change so you re-price only what shifted.
BIM Manager
Will the QS team bounce this model back with disputes?
Anomaly checks surface modelling errors before the model leaves your hands.
Contractor / Estimator
Is the take-off I'm pricing the latest revision?
Every row is traceable to a model version — no more pricing stale counts.
How it works

From file to traceable BOQ in four steps

01

Upload

Drop an IFC or Revit file. Qoloris parses every element and its geometry.

02

Quantify

Quantities are computed per element, classified, and decomposed into assemblies.

03

Review

Inspect, compare versions, and flag anomalies in an interactive 3D view.

04

Export

Excel, CostX, CSV — element IDs and classification travel with every row.

"A take-off that used to take my team two weeks now lands the same afternoon — and I can trace every figure back to the element."

"The version comparison alone paid for itself on the first tender revision. I price what changed, not the whole model again."
