3D laser-scanning and modelling.
When renovating or building a plant, a house or literally anything else there is one thing that is always needed … Exact and precise data of the structure itself and of its surroundings. Realizing a project like renovating a plant simply is impossible without access to precise measurements due to the complexity of a plant’s structure. Furthermore, our 3D laserscanning and modeling services enable your planning to be more precise and efficient, by being able to take measurements from wherever you are at the moment.
This is where we come in! We offer a detailed and cost-effective 3D laserscanning and modeling service.

Thanks to our just-mentioned 3D laser-scanning service, we are able to offer an innovative and efficient combination of services. With our detailed 3D-plans, we can easily combine this information with our “upgrading and retrofit” – services, which will give you the benefit of cooperating with only one partner. This eliminates potential mistakes, which naturally occur if multiple companies get involved. Having only one partner in such a cause eliminates potential mistakes due to insufficient knowledge of the site, which we would have gained after performing 3D scans ourselves.

millions of measuring points.
your planning safety!
Thanks to our highly educated draughtsmen, we are able to process raw laserscan-data efficiently and at a high quality. Due to our workforce, we are also able to carry out the processing for other companies, who do the scanning themselves and are in need for additional workers for high-quality processing. For more information on our 3D laserscanning/modeling services and potential test-samples, please feel free to contact us by clicking here.
Below you will find further explanations for every step of our service:
How Does It Work?
As the name “3D Laser Scanning” suggests, we use laser light in order to measure and record distances.
Let’s take a closer look on how the technology works:
1. This is the horizontal part of the scan. The scanner slowly rotates around its own axis.
2. A deflection mirror rotates in a vertical manner and deflects the laser beam in order to capture 3-dimensional data.
3. Evaluating the data of laser beams: Whenever a laser beam hits a point in space and gets reflected, its exact location (xyz) is being recorded. At the same time the scanner will notice differences in the reflectivity of surfaces and will record this by giving it an intensity value. The built-in camera also provides an RGB value to each recorded data point!
Scanning
All scanners work via line of sight, therefore multiple scans must be taken from different vantage points to ensure a complete data set.
First, a control network needs to be established in order to join multiple scans together afterwards.
To accomplish this there are multiple ways:
- Using targets in the scan such as checkerboard-targets or reference spheres (as can be seen on the picture).
- Known survey points
- Enough overlapping of the scans enables the software to recognize common features (cloud2cloud).
When scanning large objects/sites, we normally use a point-density of 3mm at 10m. This means that there is a spacing of 3mm between each point when the scanner is placed 10 meters away. As you move further away the spacing increases. Therefore, at 20m the gap between 2 dots will have increased to 6mm. It is of high importance to determine the right point-density for your project before commencing. Too low of a point-density might cause low or no visibility of key features like edges!
Modeling & Data
Project Process
One or two technicians come to the site and carry out the scan. The number of technicians depends on the size of the site.
The processing of the scans/data takes place at our office and is carried out by skilled workers. The processing time depends on the scope of a project and varies between a few day and a few weeks.
1. 3D Point Cloud (raw data!)
We provide raw data as a combined point cloud and if you wish so, we can also provide single scans. Point clouds can be delivered in many different formats.
IMPORTANT: In order to work with point clouds you must have access to powerful hardware, special software and enough hard-disc space, since it is raw data!
2. WebShare2go (web-application)
The point cloud can be provided as a web-application on a USB stick or HDD. The app requires no installation, it just works through you web browser. All scan positions are displayed in an overview map and can be opened directly. Each scan position is displayed as a 360-degree image and the app also enables you to take measurements directly through the image!
3. 3D Model (interfering contours)
This is the most requested option, because it is the easiest way to handle the big amounts of data that our 3D Laser Scanning process generates. We use the scanning data to create a simplified but precise 3D interference edge model. The 3D models are created in your desired level of detail and can be provided in many different formats suiting your project!
Example Project: Cement Plant in Gmunden, Austria
Over 200 Scan-Positions!
More Than 200 GB of Hard-Disk Space Used!
Exceeded 6 Billion Measuring Points!
For the modernization of a cement plant in Gmunden our customer ordered our 3D Laser Scanning and modeling service. The entire preheater tower, with both the stove and the control room, was digitized by us.
Separating into groups
We separated the 3D model into distinct groups and layers as our customer desired. For each cyclone stage a separate file was created and within the cyclone stage we created layers for concrete, steel structure, electrical equipment and the cyclone itself.
File Format
As it has been said already, we deliver data in various file formats adapted to your needs. In the case of our customer from Gmunden, they required STEP-format and we delivered! The 3D model itself was created in AutoCAD 3D and with special point cloud tools.
Here you can see a precise 3D Model of the plant from the outside. On the left you can see the preheater tower, in the middle there is the stove and on the right are the control rooms of the cement plant! Take a look at the highly visible details in each of the described parts! (For higher resolution samples, feel free to Contact Us!)
