3D Laser Scanning for Staircase Documentation

Project overview

Client Overview

The client needed a detailed 3D scan of an existing staircase for renovation and design verification. Accurate measurements were essential to ensure modifications fit correctly and to prevent errors during construction.

Project Highlights

✔ 1 Staircase Scanned with Precision
✔ 2 Skilled 3D Modeling Engineers
✔ 5,000+ Data Points Collected
✔ Detailed 3D Model Created for Planning

Process & Execution

The scanning process began with the Leica RTC360, a high-precision laser scanner that captured the staircase’s dimensions, angles, and spatial layout. The collected data was processed in TruView Virtual and converted into a detailed 3D model using Revit.

With an LOD 350 model, every aspect of the staircase was accurately represented, allowing for seamless integration into renovation plans.

Results & Benefits

🔹 Accurate Measurements: Eliminated manual errors and inconsistencies
🔹 Seamless Design Integration: Ensured smooth collaboration with contractors and designers
🔹 Cost and Time Savings: Reduced the risk of fabrication errors and on-site modifications

Solutions

How the result was achieved

Site Preparation – Highly reflective surfaces of the footing were covered with masking tape
Tripod-based 3D Laser Scanning – 10-20 laser scans were taken to capture the stairs and the area in general
Scan Registration – The scans were carefully processed to create a detailed, accurate 3D point cloud in Autodesk ReCap format
Scan to BIM – From the scan, an as-built 3D Autodesk Revit model was created which served as a reference for designing the new rails.

The key factor here is their knowledge that nothing is built according to plan. Even though this staircase was likely designed by computer with perfect curves and arches, if you look closely enough, you will surely find some flaw in its construction. Since things like staircase handrails usually get put in towards the end of a construction project, the staircase customer is left to deal with whatever the condition is. We’ve seen some staircase footings that are badly out of shape, forcing the staircase company to make unexpected adjustments to their project. With laser scanning and modern manufacturing, handrails can be designed to fit warped surfaces like a glove.
