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.
Our Scan to BIM process uses the 3D laser scanner to accurately capture existing conditions. The scanned data is imported into a BIM modeling environment where the "As-built" models are created, which can be Autodesk Revit, Graphisoft Archicad, or others.
This process consists of 3 main phases:
Capture of information by 3D laser scanner: It is done on site with the scanner where the equipment analyzes by means of a laser beam the distance to the elements that surround it. This results in the recording of a large number of points that are located relative to the scanner on the X, Y and Z axes. The set of scans from different locations will allow to elaborate a "cloud of points" of the entire project.
Data processing: It is done to treat the information in order to combine them and be able to work with them in the most optimized way possible. For this you can use specialized software such as Faro Scene, Leica Cyclon, Autodesk Recap or another of the market. In data processing, you must keep in mind both the use that will be given to the point cloud, as well as the technology available to work with the cloud.
BIM modeling: Which will be conditioned in large part by the BIM use we give to the model and modeling software. From the point cloud, the geometry of the "As-built" model will be generated in the chosen tool (Autodesk Revit, Graphisoft Archicad, others). To this model is that we will enrich with the characteristics and attributes of all the information received (both physical, as the cloud of points; as complementary, such as brands and models of the equipment or photos and videos that give us visual information of the project). Finally, it must be duly incorporated into the final product, as well as correctly organized and structured, so that it is easily readable from any other BIM (Building Information Modeling) software.
Benefits of High Definition 3D Laser Scanning for Entire Buildings
3D laser scanning technology has several benefits over traditional methods, which the construction industry can take advantage of:
3D laser scanners capture spatial data from the scanned structure with maximum precision.
It makes it easier for architects and engineers to better plan and design the construction project.
The process of laser scanning and generation of point clouds allows to capture geometries from a safe place, eliminating the need to access risk areas to take action.
Point cloud data provides the information as it is of the construction project for facility management operations and maintenance without project complications.
3D laser scanning provides the data needed for the renovation and modernization of structures.
Data capture by 3D laser scanning is faster than traditional methods, with the highest accuracy, providing the results in shorter timeframes.
It helps construction owners save the total cost of the construction project.
The detailed 3D model of the structure developed by scanning the point cloud facilitates a workflow optimized for construction activities.
