Use CasesBilling
Billing without measurements of your own.
Many construction sites lack a reliable basis for checking quantities and wall areas objectively.
What happens today
Stockpile and rubble quantities come from the subcontractor

Hardly any objective basis for checks
Walls are measured by hand for billing

Project: Musterstraße site
| Pos. | Item | Qty | Unit | Unit price | Total |
|---|---|---|---|---|---|
| 01 | Excavation / removal | 320 | m³ | €18.50 | €5,920.00 |
| 02 | Construction debris disposal | 45 | t | €62.00 | €2,790.00 |
| 03 | Interior walls (drywall) | 480 | m² | €38.00 | €18,240.00 |
| … | – | – | – | – |
What this leads to
High manual effort
Checking, queries, re-measuring, coordination.
Leeway in quantities and disposal
Without measurements of your own, figures are hard to verify.
Subcontractor invoices are hard to check
Deviations are often hard to trace.
Site management time tied up needlessly
Instead of steering progress, resources are tied up in billing.
Use Case 1
Stockpiles / rubble.
A 360° walkthrough becomes a verifiable volume basis for stockpiles, rubble and disposal.

How it works
1. Hover over the stockpile
Select a stockpile, rubble or a container in the 3D walkthrough.
2. Automatic segmentation
The AI detects and outlines the stockpile automatically.
3. Volume is calculated
The volume is calculated from the 3D model and displayed.
Benefits
Verifiable quantity basis
Objective, traceable volumes instead of estimates.
± 0.5% deviationFaster disposal checks
Capture and check quantities right in the walkthrough.
Less leeway in billing
Clear, verifiable data reduces disputes.
Use Case 2
Rooms / BoQ billing.
One click into the room: floor, ceiling, walls, windows and reveals are detected in the 3D model and prepared as the m² basis for BoQ billing.
How it works
1. Click into the room
One click in the 3D model is all it takes.
2. Automatic room detection
Floor, ceiling, walls, windows and reveals are detected.
3. m² as the billing basis
Net areas per room, openings deducted, mapped to the BoQ.
Benefits
Faster measuring
Entire rooms in minutes instead of hours.
Traceable areas
Every detected surface can be checked directly in the 3D model.
Better BoQ billing
Mapped directly to BoQ items, with no manual rework.
Time savings
Ten hours of measuring become two.
Per billing stage: a 360° walkthrough instead of measuring on site, wall areas detected automatically, evidence linked directly.
