Flexible working methods allow users to adapt their processes to individual project requirements and efficiently reuse existing data.

KIAVA® – The First AI-Powered Software for Bills of Quantities and Construction Cost Estimating

KIAVA® combines powerful BoQ functionality with AI assistance directly within everyday workflows. Specialized AI assistants help accelerate recurring tasks, make project knowledge accessible and improve the quality of bills of quantities.

The AI assistants support specific tasks:

• DAss enables intelligent semantic searches for information, texts and items, including across multiple projects.
• “BauTextKI” supports the creation and editing of BoQ texts and preliminary specifications, taking individual requirements and company standards into account.
• “ÜbersetzungKI” translates individual items or complete bills of quantities directly within the workflow while preserving formatting.
• “LV-PrüfungKI” reviews bills of quantities against individually configurable criteria, including wording, quantity logic and VOB requirements.

Professional evaluation and decision-making remain in the hands of the user.
AI creates more freedom for complex and demanding tasks.
