What is the Precision of 3D Laser Scanning With Existing Conditions?

Sep 18, 2020 10:40:00 AM

Building information modeling (BIM) and laser scanning has several uses in a variety of industries, including architecture, engineering, construction, and commercial real estate. With this data on hand, professionals have the reliable, realtime information about a property or structure. But in order for this technology to be useful, it needs to provide a great deal of accuracy. And not every laser scanner provides the necessary accuracy for important projects.

Incredibly accurate

But when you work with Existing Conditions, you can rest assured we work with only the most technologically advanced laser scanning technology. We use a full spectrum of laser scanning equipment from companies including Leica and FARO 3D. Depending on the project, we deploy the scanner that best fits the needs of the project.

This technology provides incredibly accurate information, but just how precise is the data? 

Let’s consider the Leica RTC 360 for example. 

Under laboratory conditions, it has impressive 18”angular accuracy, as well as range accuracy of 1.0 mm + 10 ppm. It’s 3D point accuracy is 1.9 mm @ 10m, 2.9 mm @ 20 m, and 5.3 mm @ 40 m. It gathers low noise data to allow for better images, with crisp, high-quality scans that are rich in detail and ready for use in a range of applications. It also has a measuring rate of up to 2 million points per second, as well as an advanced HDR imaging system. Ultimately, the creation of colored 3D point clouds can be completed in under 2 minutes. 

When used on actual job sites, the accuracy will never quite be exactly what the manufacturer can achieve in a sterile lab environment. But by using advanced tools like the Leica RTC 360, our team has the confidence that we are using a tool designed to be incredibly accurate.

We get you what you need

Our deliverables are driven by your scope and your needs once we’ve completed laser scanning for your property or project. We customize our level of detail to suit your needs. For example, most clients request detailed floor plans, roof plans, and exterior elevations. Some clients require additional information, including reflected ceiling plans and electrical plans. 

When quoting the project, we provide you with what will be included in the drawings and what our scope will be. Before we create CAD drawings or BIM models for you, our BIM managers will contact you to review the laser scan data when necessary to be sure we’re getting you as much situational awareness as possible.
