Scan-to-BIM

Scan-to-BIM is a process of converting point cloud data obtained from 3D laser scanning into accurate and detailed 3D models of the current situation. This technology facilitates the seamless transition from physical objects to digital representations, enabling architects and consulting engineers to continue working on an accurate and up-to-date basis.

With one of our laser scanners, a point cloud is produced, and if necessary, this is used to create a 3D model. Both the point cloud and the 3D model are georeferenced and set to scale so that accurate absolute measurements can be taken from the created models. The point cloud is well suited for visualization and further refinement and can be supplied in E57, RCP, or LAS formats. If desired, the point cloud can contain intensity values ​​or color values, for a more realistic visualization.

A 3D model is modeled from the point cloud, with the desired level of detail. This can be rough construction areas such as tunnel contours, or small details such as the decoration on a facade. Information can be added to the digitized objects, e.g. pipe type, manufacturer, theme code, pole number, infrastructure type, and much more.

This makes the data very suitable for further processing and planning in a BIM, CAD, or GIS environment, such as Revit, ArchiCAD, AutoCAD, or ArcGIS. Many tools today provide the opportunity to work with the information in such 3D models, as well as using point clouds for visualization.

2D-floor plans and facade drawings can also be produced based on point cloud data.

Scan Survey has extensive experience with terrestrial laser scanning. We use laser scanners from Leica which send and receive up to one million points per second. These instruments provide a three-dimensional image of everything the laser hits, providing a lot of data that can be collected in a short time while in the field.

We can also create  3D models by collecting data from laser scanners on backpacks as well as our mobile mapping vehicle, read more about mobile mapping.

Terrestrial laser scanning has higher accuracy than mobile laser scanning and is used in those cases where there are stricter requirements for accuracy and point density.

Geometric control

Laser scanning is a very precise and efficient method used in various industries to ensure accuracy, quality and compliance with what is projected.

We have carried out geometric checks of long piles, large concrete tunnels, precast buildings and bridges on behalf of builders.

 

 

 

Point cloud data is analyzed and compared to a reference model. The deviations are visualized as a choropleth. Coroplett provides information on where and to what extent the physical object deviates from the intended design.

Deformation control

Laser scanning can be used to monitor and analyze structural deformations, displacements or changes in physical objects. We have carried out deformation checks of facades, precast decks, sheet pile walls, etc.

Deformations can be checked against theoretical surfaces – e.g. vertical to capture plumb deviations or horizontal to check flatness.

Deformations can also be monitored over time – then periodic laser scanning is carried out at regular intervals and data is checked against the output measurement that is used as a reference.

Deformations are visualized as choropleths, which highlight areas of deformation.

Deformation control performed with laser scanning is a comprehensive and non-invasive method for tracking structural changes and ensuring the safety and longevity of buildings, bridges, dams, tunnels and other critical infrastructure. Benefits are early detection of problems, reduced maintenance costs and improved decision-making regarding maintenance and repair actions.

Construction underground

Scan Survey has built up extensive expertise in working in demanding and risky environments and has carried out several measurements in wastewater tunnels, hydropower plants, and in generally inaccessibly difficult constructions underground. We have a strong focus on safety, and have a fleet of equipment that allows us to work safely in all situations. Such work is carried out by a multidisciplinary group, with personnel from both the surveying and Real Capture departments.

Industry

We offer laser scanning for industrial purposes, including reverse engineering, deformation control, and quality control.

Laser scanning is particularly useful for objects with complex “non-geometric” shapes or free-form surfaces.

3D scanning is an invaluable tool in the daily work of design, deviation analysis, reverse engineering, and 3D modeling. With a focus on efficient workflow, precision, and quality requirements, laser scanning provides the perfect basis for further processing and analysis.

Transportation

We have helped our customers with the scanning of long tunnels, large railway stations, quays, city streets, and dark culverts. Terrestrial laser scanning can also be combined with other measurement methods where this is appropriate, for example with drone data, land-measured data or scanning with Pegasus:Backpack or Leica TRK.
