Building and Site Surveys Using 3D Laser Scanning
We provide geospatial digital surveying using state-of-the-art laser scanners, capturing thousands of measurements per square meter with speed and precision, without the risk of surveying errors. With our own FARO and LEICA laser scanners, we undertake projects throughout Hungary and internationally.
What Is a 3D Laser Scanning Survey?
One of the most advanced and efficient methods of collecting spatial data. In just a few minutes, a laser scanner can measure up to 30 million 3D point coordinates with exceptional accuracy and without physical contact. The result is a three-dimensional "point cloud" containing millions of points that digitally recreates the surveyed environment. This allows measurements to be taken retrospectively with millimeter-level accuracy, without the need to revisit the site.
Laser scanning surveys are a specialized form of 3D spatial scanning, providing significant support to professionals when surveying buildings, larger outdoor areas, and various structures. With a distance measurement accuracy of ±2 mm, an operating range of 0.6 to 130 meters, and a scanning speed of one million points per second, measurement errors can be minimized, eliminating the need for repeated on-site surveys or corrections.
Our Surveying Services:
• Creation of registered point clouds and virtual tours
• 3D modeling based on survey data, including updates to layout drawings in both 2D and 3D
• Preparation of architectural documentation (floor plans, sections, and elevation drawings)
• Clash detection (based on the existing model and survey data)
• Volume calculations (for merged stockpiles)
• Digitalization of building services systems
• Heritage building and monument surveys
Where Can 3D Laser Scanning Help?
1. Mechanical Engineering Surveys
Surveying complete mechanical systems in industrial facilities, including pipe and cable routes, steel structures, and reinforced concrete structures.
2. Architectural Surveys
Supporting design processes, detecting discrepancies between design plans and actual conditions during construction, and preparing as-built documentation upon project completion.
Heritage Building Surveys
Documenting the actual condition, original and unique architectural features, and artistic details of historic buildings for preservation or restoration purposes.
4. Residential Building Surveys
Surveying existing buildings for renovation or modification projects, including the preparation of floor plans, elevation drawings, cross-sections, and panoramic images.

Frequently Asked Questions (FAQ)
Is 3D Laser Scanning Expensive?
This is one of the most common misconceptions we encounter when speaking with potential clients. In fact, one of the biggest advantages of this method is its cost-effectiveness. Many people are surprised to learn that even for smaller surveys, the required data can be obtained at a lower cost compared to traditional surveying methods.
I'm Hesitant, but Interested. What Are My Options?
It is only natural to want to learn more before purchasing a product or ordering a service, and browsing the internet is often not enough to make an informed decision. That is why, upon request, we offer our clients the opportunity to experience the technology firsthand. We can arrange an on-site meeting at the client's premises, including a practical demonstration of the scanning method and an opportunity to ask questions. This demonstration is completely free of charge for the client.
How Quickly Can I Receive a Quote?
To prepare a quotation, we need to assess the site, preferably in person. However, if an on-site visit is not possible, we can also prepare a quote based on videos and photographs.
This is necessary because our quotations are not based on fixed rates, such as a price per square meter, but are always tailored to the specific requirements of each project.
If sufficient information about the site is available, we can prepare a quotation for the survey in as little as one day.
When Is the Best Time to Arrange a Survey?
In short: When an area or building needs to be surveyed quickly and accurately.
Even several hundred or several thousand square meters can be surveyed in just a few days, meaning that an accurate digital representation of the site can be available as early as the day after the survey.
This is particularly useful when deadlines are tight, there is insufficient time or capacity to carry out manual measurements, or existing documentation is unavailable or of inadequate quality.
How Soon Will I Receive the Results After the Survey?
This naturally depends on the size of the surveyed area and how cluttered it is. Generally speaking, for a survey completed in one day, an additional working day is required to register and clean the point cloud data. Therefore, under ideal conditions, we can deliver the 3D laser scanning results as early as the day after the survey.
What Can I Do With the Point Cloud Data?
A 3D point cloud is essentially the digital equivalent of traditional manual surveying, using modern surveying technology to eliminate the limitations associated with human error. Point cloud data can be used in a wide variety of fields, ranging from architecture and heritage preservation to crime scene investigation. Its applications are so diverse that they cannot be fully explained in just a few sentences. We provide more detailed information about the various applications of point cloud technology on our website.
I Don't Have a High-Performance Computer. Can I Still Work With the Data?
Basically, yes. A point cloud created during a survey can contain several billion measured points and may require several or even tens of gigabytes of storage space.
Nevertheless, it is possible to open and take measurements within the point cloud using free software, without the need for expensive hardware.
Of course, all workstations capable of running 3D design software can also handle point cloud data.
Can the Point Cloud Be Updated Later?
The point cloud can, of course, be updated at a later stage. If changes occur, there is no need to repeat the entire survey. It is sufficient to rescan the affected area and a small section of its unchanged surroundings to provide reference points for alignment. This means that the point cloud can be kept up to date at minimal cost, especially when combined with freely available software that allows users to open and work with point cloud data.
I Need a Floor Plan or Model Rather Than a Point Cloud. Is That Possible?
Of course. Upon request, we can create 2D floor plans or 3D models from the point cloud generated during the survey, or update existing plans and models to reflect current conditions.
How Is This Different From Photogrammetry?
Both methods can be used to create point clouds. The main difference between them is that photogrammetry generates a 3D point cloud from a series of photographs using specialized software, whereas 3D laser scanning relies on real-time laser distance measurements based on physical principles. This fundamental difference also determines the most suitable applications for each method. Although photogrammetry is an excellent solution in most cases, 3D laser scanning is the preferred method in industrial environments and situations where the reliability and accuracy of the surveyed data are essential. Measurements are carried out using tested and certified equipment, meaning that the results can also be used in cases involving forensic investigations and quality assurance matters.
Should I Choose Color or Monochrome Scanning?
Point clouds generated by color and monochrome scanning are equally accurate. Neither the number of 3D points nor the distances measured depend on whether the laser scanning is performed in color or monochrome.
Based on the above, the choice between color and monochrome point clouds should be determined by their intended use.
For example, when a survey is required for modifying or expanding an industrial facility, or for checking the flatness of an industrial floor, a color point cloud offers no additional value.
However, for heritage preservation or presentation purposes, color laser scanning is almost always the preferred choice.
