Case Study: 3D Laser Scan of Staircase

Project overview

3D laser scanning facilitates design and construction of high end stairs

There are stairs we are all familiar with, such as those in your house or on your deck. But this Arrival 3D customer deals with staircases of a completely different kind. These are ultra-high-end luxury staircases made from exotic materials and designed as if by a sculptor. Could you imagine spending a half a million dollars on a staircase? In their word, this is not unusual. That is why they utilize the accuracy and precision of 3D laser scanning to design and build their custom staircases and railings. 

When you are building steps out of a rare hardwood from Africa that was very expensive and difficult to obtain, you naturally don’t want to waste any material. There is no material to spare and every board needs to fit perfectly the first time. 3D laser scanning and the scan-to-BIM provides the confidence needed to prefabricate the staircase elements so that they can be assembled onsite without any cutting. 

Mis-measurements and mistakes often cause delays on construction projects and can have an impact on other parts of the building construction. Scanning helps keep everyone working within the same set of coordinates and measurements and can actually avoid problems and clashes that used to be par for the course when building something as complex as a modern building. This customer brings scanning in at an early stage so that their engineers are forewarned of potential issues and can address them at the design stage instead of during installation.

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. 

Results

Accurate Staircase Model Obtained

The 3D Scanning and Modeling solution provided by Arrival 3D enabled our staircase customer to design and build a perfect handrail so that when it came time for installation, there will be no surprises, delays and disappointed owners.
