What is Our 3D Laser Scanning Process?
Step 1: Mobilize
With nationwide service and fast mobilization, we partner with you to define the project scope, timeline, site conditions, equipment, and technical requirements to ensure the right 3D laser scanning solution for your project.
Step 2: Scan
Using construction-grade 3D laser scanning, we quickly and accurately capture your building or site, including architectural, structural, and MEP layouts.
Step 3: Process
We clean, align, and register 3D laser scan data into a unified point cloud, creating a reliable foundation for models and drawings.
Step 4: Produce
Based on your specifications, we convert scan data into custom deliverables like 3D BIM models, 2D CAD drawings, and floor plans in your preferred format, such as Revit, AutoCAD, and Navisworks, ready for immediate use.
Step 5: Review
Every deliverable is quality-checked for accuracy and prepared for seamless integration into your workflows. Your final approval ensures everything meets your expectations.
Step 6: Support and Consulting
You receive expert guidance and priority support to maximize the value of your as-built data, keeping your project on time, on budget, and safe.
