From our own projects

See how others use it on real projects.

PROTTOBau grew out of our own project work across the EU. This is how we use it week to week — as project managers, construction managers and with our contractors.

"Our weekly site walkthroughs run over an hour — discussions, decisions, instructions. PROTTOBau records it all, so I stay in the conversation instead of taking notes. Afterwards I check every point against the project information, and when something is a change order, I raise it early — before we pay twice."

Recognizes The Discussion & Structures The Right Report.

PROTTOBau doesn't transcribe — it comprehends. It recognizes whether you're reporting a defect, running a handover, or logging a daily update, and automatically applies the right report structure.

Validates Reports Against Project Data.

ProttoBau Intelligence compares completed protocols against project drawings, BOQs, specifications, schedules, change orders, and other project information to identify inconsistencies, potential risks, and commercial impacts before they become costly.
