Manhattan Commercial Building
989 Sixth Avenue — Scan-to-BIM & As-Built Case Study
How Heleos VDC produced trustworthy as-built documentation for a 989 Sixth Avenue renovation using 3D laser scanning and scan-to-BIM.
Project Facts
- Location: New York, NY
- Building type: Existing Manhattan commercial building
- Primary service: 3D Laser Scanning & Scan-to-BIM
- Services used: 3D Laser Scanning, Scan-to-BIM, BIM Coordination, MEP Coordination
- Tools: Leica, FARO, Autodesk Revit, Navisworks Manage, Autodesk BIM 360
- Deliverable: LOD 300 as-built Revit model
The Challenge
Renovating an existing Manhattan building means the legacy drawings rarely match what is actually in the field. The team needed reliable as-built documentation before committing to renovation and MEP upgrade decisions.
Our Workflow
- Laser scan the existing interior conditions and register the point cloud to a single coordinate system.
- Author an LOD 300 as-built Revit model from the registered scan data.
- Quality-check the model against the point cloud to verify accuracy.
- Coordinate proposed MEP routing against the verified existing conditions in Navisworks Manage.
- Deliver the as-built model and coordinated backgrounds through Autodesk BIM 360.
Tools Used
- Leica laser scanner
- FARO laser scanner
- Autodesk Revit
- Navisworks Manage
- Autodesk BIM 360
The Outcome
An accurate, QC-verified as-built model that gave the design and construction teams a trustworthy basis for renovation decisions and reduced the risk of field conflicts during the MEP upgrade.
Service & Location Summary
This Manhattan project shows how Heleos VDC delivers scan-to-BIM and as-built documentation in New York — turning survey-grade point clouds into accurate Revit models that de-risk renovation work in existing buildings.
Frequently Asked Questions
What is scan-to-BIM and how was it used at 989 Sixth Avenue?
Scan-to-BIM is the workflow of capturing an existing space with a 3D laser scanner and authoring an accurate Revit model from the point cloud. At 989 Sixth Avenue it produced an LOD 300 as-built model verified against the scan data.
Why scan an existing building before renovation?
Legacy drawings rarely match field conditions. A scan-based as-built model gives the team verified existing geometry so renovation and MEP coordination decisions are based on reality, not outdated documents.
