For project owners
Know the number before you break ground.
You have the land and the drawings. Before you commit financing, you deserve quantities you can take to a lender or a builder — not a gut feel. CAIRO reads the drawing set and returns the counts behind the cost.
What the building actually contains
Units, floors, rooms, doors, windows, finishes — counted from the drawings themselves, not estimated from square footage.
A number you can defend
When a builder quotes you, you hold an independent quantity baseline to negotiate against.
Honest gaps, declared
If a dimension is not in the document set, your sheet says so — in gold — instead of hiding a guess inside a total.
The audit trail
What an owner sees
A takeoff per trade, with every count traceable to a sheet in YOUR drawing set. Question any number — it answers with its source.
