The use in synergy of BIM with laser scanner survey techniques has brought numerous benefits to the AEC industry. The Scan to BIM process can be further improved thanks to the integrated survey techniques, let's see what the advantages are for surveys and the creation of point clouds.

The topographic surveys

To carry out any type of project, be it the construction of a new building or the renovation of a pre-existing construction, the starting point for doing a good job is the knowledge of the territory and the site where the building is located.

This is possible through the topographic surveys, to be created with the most suitable technologies based on the type of site you have in front of you.

Over the years, the technologies available to us for topographic surveys have multiplied, becoming ever more more precise and efficient, and today it is possible to carry out surveys using for example:

  • GPS measuring systems;
  • Total stations;
  • Photogrammetry;
  • Drones for aerial surveys;
  • Laser scanner 3D.

In recent years, important technologies have been added the synergic use of BIM, which gave rise to the process Scan to BIM and brought numerous Benefits to the AEC Industry.

What are integrated survey techniques?

BIM was born as a methodology for the construction of new projects and buildings, but more and more often it comes also used to obtain a digital model of existing buildings, particularly historic buildings and those of high architectural value.

For this reason we often have in front of us particularly difficult surveys to carry out and which can create numerous problems, in particular in the case of:

  • Complex or large buildings;
  • Internal and external areas of the building;
  • Historic buildings with unique architectural shapes;
  • Constructions in difficult areas or with complicated logistics, etc.

The best solution in these cases is to use the integrated relief, or the synergistic use of more techniques and instruments for surveying, to obtain more precise data acquisition and have a coordinated workflow.

The advantages of using integrated survey techniques and Scan to BIM

Using integrated survey techniques has numerous advantages and is considered one of the best methods for carrying out surveys for projects of historical and architectural importance.

Working with integrated relief:

  • Makes the workflow more efficient and faster;
  • Reduces the margin of error;
  • It allows you to reduce time and costs;
  • It provides more data and information for the Creating more accurate point clouds.

About point clouds, the integrated reliefs simplify the process of creation and joining also thanks to thesynergistic use of different solutions and software for their extraction.

Using multiple interconnected software allows you to:

  • Increase the productivity;
  • Have more check on the data;
  • Check already on site the accuracy and quality of scans to immediately optimize the point cloud; 
  • Working on the point cloud already in the pipeline, eliminating unnecessary data and overlapping scans to make it lighter, easier to share and Start the Scan to BIM process to obtain a digital As Built model of the building.
