Laser scanning, BIM and UAV (drone) mapping are cutting edge survey technologies that greatly benefit infrastructure projects ranging from civil, building and mining projects.
All new builds or refurbishment projects require accurate and up to date plans of the existing reality – On the commencement of a new build, refurbishment or facilities upgrade
The basis for all of this is a good 3D Point cloud translated into an intelligent CAD or Revit model of the current reality.
A point cloud is a digital scan of reality. A tool for the cost efficient, rapid and precise high definition capture of 3-dimensional data. 3D modelling from the point cloud then allows for the visualization of complex structural interactions. Most importantly, it significantly reduces design ambiguity, making it more straightforward for you to get across your design intent and to be flexible and responsive to collaborative input.
Laser scanning and 3D modelling is a cost-effective tool that uses laser beams to capture the complete visible data of a building, construction site or facility – much like a 360⁰ photo with each pixel having an accurate position converted into a virtual reality intelligent model.
Benefits of 3D scanning and Revit / BIM modelling
How does laser scanning work?
A laser scanner sends out a million points a second that when a point reaches an object, the position of the object is recorded together with the points RGB value for a more intuitive display of point cloud information. After the fieldwork is complete the individual scans are collectively registered to create the “point cloud” of the building, structure or plant being modelled.
From this “point cloud we extract a 3D cad model in Revit or similar Cad software combine with intelligent extraction process. We currently find a combination of extracting individual elements such as a beam, a wall or a pipe automatically, combined with use of manual authoring of connections between these elements is the most efficient solution for crafting a Cad model in Revit, Microstaion or other formats requested by client.
Good detailed maps, site plans and terrain modelling are necessary components for all successful infrastructure development projects. Greenfields projects, infrastructure upgrades and the comprehension and management of assets all benefit from visual intelligence in the form of accurate 3 Dimensional geospatial data. UAV (Drone) based mapping has become the most effective solution to improve decision making and increase productivity and effectiveness of project management and design teams.
UAV aerial mapping allows for the cost efficient, safe and accurate mapping of 1 – 15 Km² areas of mapping data. The mapping can be carried out without interrupting asset management, mining or construction operations in a safe manner.
For use in: Infrastructure planning, asset mapping, mining operations, stock-pile and quarry volume reporting, digital terrain modelling , site and route selection and agriculture planning and crop analysis and condition monitoring.
There is a common misconception that BIM means 3D design. In fact, it’s much more. BIM is a process for creating and managing all of the information on a project – before, during and after construction. The output of this process is the Building Information Model, the digital description of every aspect of the built asset.
BIM is an intelligent model-based process that provides an understanding of reality leading to improved planning, design and management of infra-structure.
“BIM is the visualization of data. You can be seduced by the visualization, but the real return on BIM is in the enhanced quality of the data. One of the ways you achieve that higher data quality is by being able to visualize what you’re doing. All of the data we exchange with architects and others on a project is now 3D. Everyone on a project works and collaborates better by being able to see and understand the project as a whole.”
