University of Salamanca takes part in the development of a land drone that automates the certification and quality control tasks in civil works

Dron_1 TIDOP Research Group , within the framework of the Auto-BIM project,  has developed a land drone able to make the certification and quality control tasks of civil works in different construction stages.

Auto-BIM Project, in which the TIDOP Research Group together with Vías & Construcciones, Aplitop, Aplicad, Aimen Technological Center and University of Vigo, has developed an innovative tool to certify civil works with much more accuracy and quality than traditional systems used up to now by the different construction and certification companies.

The main goal of the Project, funded by MINECO and CEE with around 1.000.000 €, is to develop a land drone that will automatically audit the current state of civil Works, and compare it with the initial or theoretical state it should be in. For this purpose, the consortium has built a land drone armed with different last generation devices such as terrestrial laser scanner (TLS) for perform the three-dimensional radiography of the environment, several obstacle detectors and one route planner to enable self-orientation of the drone everywhere.

After the acquisition, all the captured information is processed by the software developed for this Project. It allows to compare the As-Built model (real state of the Works) with the BIM model (theoretical model projected). The construction companies can undertake quality control and certification tasks faster and more flexible, having much more data than with the traditional systems of acquisition and certification.

For the test of, both the drone and the processing software, a pilot test was carried out in a civil work located in Badalona (Barcelona). The chosen site, was in different stages of construction, so there were areas of pillars, areas of vertical walls etc, so the drone had to be able to transit through the different scenarios autonomously and optimizing the three-dimensional model in each case.

The results of the pilot test were a success, both in terms of the navigation of the drone inside the civil work as well as what refers to the data obtained and the software for processing them.
