In the construction sector, there is an increasing need for specialized surveys carried out with a high level of accuracy. In many cases, high-precision three-dimensional surveys are essential in order to inspect and dimension structures, as well as to assess their deviation from the original design specifications.
By applying 3D Laser Scanning methods – three-dimensional imaging and modeling – we obtain accurate data regarding the behavior of structural elements in constructions with special requirements. Given the rapid technological advancement, modern 3D scanning systems are capable of collecting millions of points in space, forming what is known as a point cloud.

Scope of 3D Laser Scanning for Civil Engineers and Architects
In the field of design and construction, the level of detail plays an important role.
With three-dimensional building modeling, engineers are provided the ability to study the exact features of interest and use them to extract information regarding:
- The structural inspection and any damage that may have occurred to the load-bearing framework of existing buildings
- Architectural studies of interest, such as renovations and reconfigurations of interior spaces
- The preparation of drawings (floor plans, elevations, facades, sections) for additions to existing structures
- The cost estimation of constructions
- Creation of Building Information Modeling (B.I.M.)
3D Modeling of cultural heritage monuments using Laser Scanning
The primary purpose of applying three-dimensional documentation to buildings related to our cultural heritage is the maintenance and restoration of damage and deterioration caused by the passage of time. Additionally, the 3D Laser Scanning technique is also suitable for specialized applications, such as:
- Restoration and scientific analysis of data for the protection and safe operation of historic monuments
- Virtual presentation of historic areas where access is not permitted
- Photorealistic three-dimensional models of the space
- Detailed documentation of excavations
Installation and upgrading of mechanical equipment
This method also has a wide range of applications in the industrial sector. The electromechanical equipment used in industrial facilities requires absolute precision in the design and implementation process. In general, metal structures require special handling, given that there is no flexibility to change their dimensions. A natural consequence is the documentation of geometric measurements both before and after their construction and installation. The 3D visualization process is applied in:
- Maintenance and upgrading of mechanical equipment
- A priori inspection and sizing of the equipment to be installed
- Training of personnel through three-dimensional models
- Improvement of work scheduling
3D Laser Scanning in Shipping and Shipbuilding
In the maritime sector, the requirements for ship construction are particularly strict, as defined by the legislative framework and manufacturers' standards.
Therefore, geometric documentation and data analysis aimed at verifying and ensuring the correct application of construction standards are necessary. Areas of application may relate to:
- Digitization of ship components or sections into two-dimensional or three-dimensional drawings
- Inspection of the repair process
- Three-dimensional representation of the space in the case of interior reconfiguration of a vessel.
