The Importance of Building Information Modelling Surveys

2d Plans are the standard, but they do not give you the same intuitive view as a 3D model, and virtually any architect or building designer will be able to tell you this. That being said, BIM surveys or Revit surveys are your best option when it comes to providing an accurate intelligent representation of any building. For instance, building information modelling surveys will give you virtually anything you need in that regard. In addition, with many refurbishment schemes in the pipeline, the cost of surveying an as-built environment and delivering the data set in a BIM format direct to the user is becoming extremely attractive - both from a functional, accessible and economical point of view.
When it comes to building information modelling surveys, laser scanning instruments will be employed to collect accurate data at 500,000 points per second, and these measurements will be collected as three dimensional point clouds. As a result, the 3D digital information collected can be accessed in real time and will allow you to make immediate informed decisions to assist in the design process. This initial process provides the base data to construct your Building information Model in Revit.
Once laser scanned, high dynamic range photography can be overlaid which will provide a more user friendly representation of the building in question. This can be viewed, via the web, through 'TruView' and becomes an interactive 3D decision tool, allowing the viewer to measure, hyperlink, investigate coordinates, add text and virtually 'walk' around the building.
Utilising both laser scan data and high dynamic range photography enhances the final 3D deliverable, whether it is 3D wireframe, solid model or a building information model.
This scanning technology and software has revolutionised measured data collection and aligned itself with the new advances and up take of building information modelling in the construction industry. Revit surveys with this methodology are in complete alignment with the holistic approach that BIM is advocating. The ability to have a geometrically frame worked model of a built environment, delivered in Revit at the earlier stage of design or development has significant time and cost savings throughout the whole process.
The advantage of always being able to return to the raw 3d data also has major advantages in this holistic approach. In today's competitive business world, where efficiency and the ability to save costs is paramount, having an accurate geometric framework is a must.
