Facade Surveys

Façade & Exterior As-Built Surveys

Accurate • Laser-Scanned • BIM-Ready • Ideal for Renovation & Restoration

(Serving NYC, NY, NJ, CT, PA, MD, MA, and the DC Metro Area)

We provide high-accuracy façade as-built surveys using advanced 3D laser scanning, photogrammetry, and point-cloud documentation across the Northeast and Mid-Atlantic. Our exterior as-built deliverables give architects, engineers, and building owners the precise measurements they need to design confidently—without relying on outdated drawings or manual field measurements.

If you are planning a renovation, restoration, historic preservation project, or exterior upgrade, our façade as-builts ensure you start with verified, dimensionally accurate existing conditions.

We have produced hundreds of façade surveys for building restoration companies, developers, architects, and engineers. Below shows a NYC façade survey with a colorized point cloud and basic façade drawing (Manhattan, NY).

Why Façade As-Builts Matter

Exterior walls, windows, parapets, architectural details, and façade elements often vary from original drawings—or have changed over decades of repairs and modifications.
Accurate façade documentation helps project teams:

Eliminate guesswork during design
Avoid costly field verification
Support restoration and exterior detailing
Coordinate window replacements or façade upgrades
Capture true dimensions of historic or irregular façades
Integrate the exterior geometry into BIM models
Ensure alignment between structure, interior, and exterior elements

Our façade as-builts provide reliable, high-resolution data for any exterior-focused project.

Export to Revit, IFC, Rhino, AutoCAD

High-Resolution Exterior Photography

Photo documentation of the full building envelope
Optional drone photography for taller or hard-to-reach façades

(Note: We do not perform condition assessments, engineering investigations, or façade inspections. Our focus is strictly on accurate as-built documentation.)

Our Exterior Survey Process

1. Pre-Survey Planning

We review any available drawings and define the scope, access requirements, and scanning strategy.

2. On-Site 3D Laser Scanning

Using high-precision scanners, we capture millions of 3D measurement points across the entire building façade.

3. Supplemental Photography

High-resolution terrestrial or drone photos support CAD/BIM modeling and documentation clarity.

4. Point-Cloud Registration & Processing

All scans are registered, cleaned, and merged into a cohesive, accurate exterior point cloud.

5. CAD or BIM Production

From the point cloud, our team produces detailed:

Façade as-built drawings
Scan-to-CAD elevations & sections
Scan-to-BIM façade models

6. Digital Deliverables

We deliver drawings, BIM models, point cloud files, and imagery via secure digital transfer.
