From the first defect to the final completion notice: record defects on mobile with photo and plan location, assign them — and let reports, notices of defects and deadline tracking be handled automatically.

Construction Defects is the defect management software by Open Experience for the construction phase: construction defects are recorded on site by smartphone or tablet with photo, location and responsible party, assigned to the contractors with a deadline, and tracked through to the completion notice — including acceptance and the warranty phase. Reports and notices of defects are generated at the push of a button, and deadline tracking runs automatically.
Take a photo, tap the location on the plan, pick the trade and the responsible party — done in seconds. With plan server sync and BIM/IFC import; offline mode even handles the basement with no signal.
The AI recognizes the construction defect in the photo and creates the entry in structured form — you review, complete, assign. Built in our own research, trained on more than 200,000 real construction site images — GDPR-compliant, servers located in Germany.

Acceptance reports, defect lists and formally correct notices of defects are generated at the push of a button from your records — ready to send as PDF.
„Generating reports at the push of a button has become so effortless that acceptance walkthroughs, report included, now take only a fraction of the time.“
Every defect notice gets its deadline. The system reminds, escalates and documents — up to the formal notice of defects with a grace period, and the follow-up request is prepared automatically. Subcontractors submit completion notices via free accounts.
Limitation periods in view (VOB/B, the German construction contract procedures: 4 years; BGB, the German Civil Code: 5 years), every warranty defect documented and assigned — reported via the app, through a dedicated email address or directly by the tenant via the QR code interface.
Works together with: Construction Photos (photo documentation), Construction Diary (daily site reports), Construction Time (deadlines), DIGIBAU 360 (walkthrough capture) — one project, no duplicate data entry.
Construction Defects covers the entire process — from the walkthrough through rectification request and completion notice to the warranty phase. All features at a glance:

A photo becomes a defect: the image recognition detects typical construction defects and creates the entry in structured form — you review, complete and assign. The AI works exclusively with your project data, GDPR-compliant on servers in Germany.
Beyond the classic construction defect, e.g. occupational safety, obstruction, outstanding work, damage report, planning notice and additional work — each type with its own document templates and up to three escalation levels, from the rectification request to the formal notice of defects with a grace period.
