What Is The Precision Of VLX Scanning?

Feb 17, 2022 2:36:21 PM

3D laser scanning and building information modeling (BIM) is used for several applications in fields such as architecture, engineering, and construction. Professionals are now able to get real-time information on properties thanks to this data. For the technology to be useful, it must also provide a high level of accuracy. Every project comes with its own requirements, and Existing Conditions uses a variety of scanning technologies to meet clients' needs, including the new NavVis VLX.

VLX Scanning is Incredibly Accurate 

Working with Existing Conditions brings confidence, knowing that we work only with the latest, most advanced scanning technology. Our scanning equipment includes laser scanners from Leica and FARO, drones from DJI Technology Co., Ltd, and the NavVis VLX. Depending on the project, we deploy the scanner that best meets the client's needs.

How does this advanced technology work and provide precise data?

Let’s consider the NavVis VLX for example. 

The NavVis VLX can handle everything from complex indoor spaces with challenging light conditions to outdoor environments and construction sites, with speeds up to 10 times faster than terrestrial laser scanners. A unique SLAM algorithm has been developed for the NavVis VLX that is specifically designed to overcome the challenges of capturing high-quality point clouds with a mobile device in all types of conditions.

Tools like the VLX, give architects, building owners, commercial real estate professionals, and facility managers the opportunity to understand their buildings in a very quick and cost-effective manner so that they do not have to take unnecessary risks. 

The VLX is different from our terrestrial scanners, which are static and mounted on tripods. The VLX is a wearable device. Just think how long it would take you to walk around your office, your space, or the entire building. That is the time required for your scan. It's a tried and true workflow and your team will not be inconvenienced in any way. The day can carry on as normal.


The VLX utilizes a class one laser, meaning that it is not more intense than what you would see at the supermarket checkout. Here at Existing Conditions, we scan many museums and historical sites. The VLX laser, like all of our 3D scanners, will not damage artwork or any artifacts that are displayed in these buildings.

Since the laser beam is invisible, there are no distracting lights interfering with people’s daily activities. There's really nothing intrusive about it other than seeing somebody walking around with a device on their shoulders. “It's extremely efficient, fast, and precise," states Kurt Yeghian, Existing Conditions CEO.

We get what you need

After scanning your project, we will provide customized drawings and deliverables that meet your requirements. As an example, most clients request detailed floor plans, roof plans, and elevations, while some clients also request reflected ceiling plans and electrical plans. We can provide what you require.


In our quotes, we describe what will be included in the drawings. Our BIM managers will contact you to review the data when necessary to be sure we’re getting you as much situational awareness as possible.

Whether you're designing, managing, or buying a building, Existing Conditions provides you with an understanding of your most valuable asset, and gives you unprecedented situational awareness, something you will not find when looking at old rent rolls and paper drawings. This process allows you to make good decisions based on accurate data, and not assumptions from inaccurate rent rolls or historic paper drawings
