3D Laser scanning services & As-Buit Surveys

We rebuild the geometry of elements and infrastructures using 3D laser scanner technology

Full buildings scan and drawing up plans

With 3D laser scanner we make the precise registration of all facilities and assets that will be used for mapping, as well as for the lifting of plans or updating existing ones. We use the market design tools Autodesk Revit, Autocad, Archicad, Solid Works, and others, with significant time and cost savings. Once the three-dimensional plane survey has been carried out, we can offer the 3D modeling of the scanned spaces for the creation of a BIM (Building Information Modeling) model.

When faced with the task of creating plans for an existing structure we know how difficult it can be. It is rare for buildings to have a simple form. Using a distance meter or measuring tape is a tedious and difficult job, which then has to translate into specifications on plans and trust that no mistakes were made or features were omitted.

3D laser scanning

In these cases it is better to consider the alternative of 3D laser scanning. A long-range 3D scanner can capture complete environments in minutes with the press of a button. With each scan, save a cloud of color points with an accuracy of 4 mm or less. With enough scans, you can capture a complete installation (e.g. a house) before the end of the day.

 

Creation of plans, plan views, elevations and sections from a laser scanning project:


With a 3D laser scanning project, 2D planes can be created in two ways:

 

  • Extract 2D orthoimages or scan cuts for direct viewing and redraw over the scan sections to obtain standard 2D DXF / DWG line drawings.

  • Generate standard drawings of BIM software such as Revit after creating the 3D CAD model.

 

It is common that most of the plans of buildings constructed are inaccurate and incomplete. If the renovation is designed based on obsolete or incomplete plans, the errors will be transferred to the new design. These errors will remain invisible until the construction phase, when their resolution already has a high cost.

 

The best way to avoid these surprises is to perform an As-Built laser scan and capture the complete information about the space to be renovated. This capture will require scanning all areas of the building involved in the project, then recording or joining the data from the point cloud.

 

 

If plans already exist, the point cloud should be oriented to match the coordinate system of the planes and align both sets of data, so that the captured data can be compared with existing ones.

 

If there are no plans, the scan data can be used as a "template" to create the new documentation. The point cloud can be divided horizontally to expose a plan view to create precise floor plans, or split vertically to expose elevation views or sections for plotting.
