🎯Understanding Level of Accuracy (LOA) in Scan to BIM

Getting the Level of Accuracy (LOA) right is crucial for the success of any Scan to BIM project. The U.S. Institute of Building Documentation (USIBD) defines 5 LOA levels:

✅ LOA 10 (50mm+) – Conceptual planning
✅ LOA 20 (15–50mm) – Early design development
✅ LOA 30 (5–15mm) – Standard accuracy for most projects
✅ LOA 40 (1–5mm) – Suitable for fabrication and construction
✅ LOA 50 (0–1mm) – As-built documentation & facility management

⚠️ Common Pitfall: Higher LOA isn’t always better. Over-modelling can waste both time and budget.

🔑 Best Practice: Clearly define your LOA requirements at the start, ensure high-quality scanning, and strike the right balance between precision and efficiency. Effective communication with stakeholders is key to avoiding rework and ensuring alignment across the project.

🚀 Scan to BIM: Proven Time Savings in Construction

Research shows that Scan to BIM technology saves an average of 59.5% project time, with even greater results in specific areas:

🔹 Automated Processes – Up to 90% faster using advanced automation.
🔹 Less Rework – 85% improvement, cutting errors that used to take 12–15% of project time down to just 1–3%.
🔹 BIM Model Creation – 50% faster for HVAC and MEP with scanning workflows.
🔹 Inspection – Quality checks cut by 71%, from 7 days to only 2 days.
🔹 Drone & Mobile Scanning – Up to 70% quicker site data capture; UAV LiDAR surveys finished in 1 day instead of 10.
🔹 Drone Corridor Mapping – 80–85% faster than traditional methods.

📈 Real Impact:
A 15-story renovation project saved 1,143 hours, and full BIM adoption shortened schedules by 35%.

With tools like laser scanning, drones, and mobile capture, tasks that used to take weeks now take just hours—without losing accuracy. Scan to BIM speeds up delivery, improves precision, and reduces costly rework across construction projects.
