How EnvelopX turns a single drone flight into a structured, AI-powered building intelligence report
Facade inspection without scaffolding. Every anomaly pinned to a 3D model with confidence scores, severity and repair-cost tracking built in.
Estimate
~70%
Estimated inspection cost reduction against the scaffolding-based method, with no scaffolding install, no rope access and no crew delay
Estimate
Days → Hours
Time from drone flight to intelligence report, with a single flight processed same-week
Shipped
3
Severity tiers (Critical / Moderate / Low) plus 4 action states per anomaly, so triage becomes structured, not narrative

Book a working sessionThe Challenge
Commercial building inspections are slow, expensive, and dangerous. Traditional methods require scaffolding or rope access to inspect facades and hard-to-reach areas, adding weeks and significant cost. Even when data is collected, findings are documented inconsistently, making it difficult to track anomaly trends, assign repair responsibilities, or generate audit-ready reports. No platform existed purpose-built to turn drone imagery into structured, trackable building intelligence.
What Attri Built
EnvelopX is a full-stack AI building inspection platform turning drone footage into a structured, actionable intelligence report. Attri built the software and AI platform; third-party operators capture the imagery, and EnvelopX delivers the intelligence layer on top.
- Automated flight path planning: drones capture hundreds of high-resolution images from every angle, including rooftops and facades inaccessible to inspectors, without manual waypoint setup
- Photogrammetric 3D model reconstruction: imagery processed into a photorealistic 3D model that serves as the inspection canvas
- AI anomaly detection: computer vision models scan every image and pin detected anomalies (structural cracks, concrete spalling, moisture intrusion) directly onto the 3D model with confidence scores
- Side-by-side review panel: each anomaly shows the original image alongside the AI-highlighted version, with confidence score and action buttons (Repair / Defer / Ignore / False Positive)
- Severity classification: Critical, Moderate and Low for triage prioritisation
- Anomaly History module: trend charts across inspection runs, repair cost tracking with GL code support, vendor assignment, and Excel/PDF export
The Outcome
Facade inspection without scaffolding. The safety risk and week-long install cost of traditional inspection are replaced by a single drone flight
Every anomaly is structured, not narrative. Repair, defer, ignore or false-positive decisions live in the platform with confidence scores and severity attached
Trend tracking across inspection runs. The Anomaly History module turns single-inspection findings into a longitudinal building-health picture
Cost and vendor tracking built in. Repair spend is logged with GL-code support and assigned vendors, exportable to Excel/PDF for audit
The customer-value payload
EnvelopX replaces the safety risk, week-long install and inconsistent narrative documentation of scaffolding-based facade inspection with a single drone flight that produces a 3D model, a pinned-anomaly report with confidence scores, and audit-ready cost and vendor tracking, delivered same week.
