Techniques used in the expertise of buildings following natural disasters

As we all know, the owners of buildings ravaged by natural disasters are compensated by insurance companies. Therefore, in order to be certain that the building has suffered the consequence of any natural disaster, different expertise techniques are required. You will find in this article these different techniques used.

Digital technology to help disaster victims

Knowing that we are in the digital age, how can we not talk about this technology if it can help in the expertise of buildings after natural disasters or catastrophes. After floods or earthquakes, for example, to review the condition of buildings, you need to use digital services. Why is this necessary? To obtain the real image of the buildings after the disaster in order to compare them with the images before. This to make the necessary calculations on the real values of the damage. As mentioned above, the damage is reimbursed by the insurance company. Digital photos and digital cameras are useful. Digitization is undisputed by the insurer. It is a concrete proof to obtain the subsidies you are entitled to.

How does digitisation work?

First, the digitization is done in 3D. Then the 3D images are transformed into 2D for processing in computer-aided design programs. It is with these CADs that we model the final images of the building. Companies like Scan 3D do these services. The digitization as well as the scans are therefore at the service of the disaster victims. Which also brings us to the second technique: modelling.

Modelling for the services of the inhabitants

After scanning and 3D digitizing, we proceed to modeling. But what is it exactly? Also called three-dimensional modeling, it is the step used to create in 3D buildings that are almost or totally destroyed after a disaster. With the help of software, the modeling is done to obtain a result as close as possible to reality. This is a specific field, but some companies also specialize in this activity. With modeling, anything is possible. Even the landscape around the building can be reconstructed. Apart from using companies, you can also buy a software and master it to get the result you need to be reimbursed by the insurers. This step is more than magical, especially for crack modeling. The latter is the act of modeling the propagation of cracks. The repair of the cracks in addition to what was present is charged by the insurances.

The 3D scan application to bring buildings back to life

Finally, here's one last method. The use of 3D scan applications on smartphones. From your smartphone, you can reconstruct the image of your building after a natural disaster. The results are kept for previous uses. The data is close to reality since the difference is in millimeters. Even after the repair you have to look at the data for a verification of the work done. But also for a virtual visit in the building for cracks or other damages inside the house.

What are the advantages of using 3D scanning?

Indeed, a digital 3D laser travels through the building to produce a file that can be processed in computer-assisted or CAD programs. This data can then be used in various studies and surveys, because even points invisible to the naked eye are captured. This is the special feature of this method. The speed offers an advantage for those who practice it. In only 3 minutes you can get a concrete picture of the building. To conclude, there are several techniques that can be used as formal proof. The techniques mentioned in this article are the most used nowadays, because they follow the technology and are reliable. As a result, the results are admissible by insurance companies to compensate you after natural disasters (floods, earthquakes, drought, cyclones, etc.).
