Advantages of 3D scanning
- Effective construction scheduling and implementation monitoring
- Thanks to the colour map visualization, faults can be corrected more quickly
- Preliminary feasibility analysis and clash detection
- Quantity calculation and cost estimation
- The scanned data set showing the original state of a building and the planned model can be displayed together
- Control of the building activity, consulting and tracking
- The building site can be assessed rapidly; more detailed results in less time, compared to traditional methods
- The data file is lasting and will be available any time to facilitate any kind of end result, or to be used in the course of fulfilling future demands
- The point cloud can also be used to inspect alternatives and hypotheses without the need to realize further local assessments
- The data file created also facilitates interdisciplinary research
- The surface connections can also be traced
Spread of 3D technologies
3D technologies such as in-space planning, spatial visualization and displays, or spatial printing are currently going through a revolutionary development.
More and more advanced instruments (such as scanners, printers, monitors), and software (digitalizing and CAD/CAM/CAE software) are gaining more and more application areas within the fields of industry, life sciences, culture and entertainment,
3D scanning, 3D digitalizing
3D scanning is essentially converting physical objects (like products, instruments in mechanical engineering) into digital data files. Scanners map the whole surface of the geometrical shape into a point cloud or polygon cloud without touching the object itself.
Special software available with the equipment can be used to process the resulting data file and to prepare it for further tasks (such as reverse engineering or quality control).
The most advanced terrestrial laser scanner can record up to one million points a second. The density and distance between the mapped points can be altered in the function of the job in question. We use a GNSS (Global Navigation Satellite System) receiver to connect the results of the terrestrial laser scanning to the unified national orthography (abbreviated as EOV). The lasers in the terrestrial scanners we use are classified as Class I, meaning that they are not harmful to human health.
The point cloud data sets and high resolution digital photographs obtained in the process of 3D scanning facilitate fuller and more accurate documentation of buildings.
3D technology solutions
Traditional measuring technologies used in quality control can be time consuming and expensive. This is where comparison and verification of the 3D scanned model and the original CAD data can help. The comparison report, prepared as a result of the quality control, includes a colour-mapped visualization, which shows all points of deviation from the plan in an easily identifiable manner. Apart from the ability to decide whether the parts of the structure that have already been built have been done so appropriately, it is also possible to define where modifications should be made.
Reduction of planning faults with clash detection
The coordination of trade and the system is a critical work procedure for every building constructor. Traditional 2D coordination solutions are time consuming, costly, prone to faults and their use is highly dependent on how up-to-date the plans are. The BIM based clash detection instruments facilitate the combination of automatic, geometry based collision inspections with semantic and rule based collision analysis to identify qualified and structured collisions.
Building Information Modelling
BIM is the digital representation of the physical and functional characteristics of a facility. It is the newest generation of OOCAD systems, in which building plans are identified as the entirety of all intelligent building objects. The Building Information Model is a unified, logical and coherent source of all data related to the building. The BIM is a reliable basis for managerial decisions throughout the whole life cycle of the facility, which extends, based on a standard definition, from the elaboration of the first concept to the demolition of the building. 3D laser scanning can be used effectively both in recovery works and for the documentation of building structural elements.
