## From room book to costing, without losing a square metre

### About 150 rooms, and every area counts for years

Ziva carries room group, floor type, area and interval into a costing with formulas. Hours and costs appear with your values.

Screenshot: Site costing in Ziva: room groups of the town hall with floor type, area and interval from the room book, hours and costs still empty.

### The city’s calculation workbook does not always add up

One active filter and you work with 2,006 instead of 4,298 m². Ziva lists every issue with sheet, cell and a question for the buyer.

Screenshot: The “Prüfung B” sheet in Ziva: issues in the City of Opfikon calculation workbook with priority, sheet, cell and finding.

### Your output rates are your know-how, not part of the template

Ziva sets up yellow fields for your rates, with the city’s given values and their cells next to them.
