At Sacyr, not only do we bear witness to the dizzying transformation in recent years resulting from applying technology to construction, we also play a part in it. An example of this is the Pandora project, an RD&I success story at our company, developed in conjunction with Aplitop and Atyges.
This technology allows us to create a 3D map of the surroundings through sensors installed in unmanned land or aerial vehicles. The information collected in interior or exterior locations and their 3D replications help us to assess, monitor and control the on-site situation.
Pandora has high-resolution vision which is capable of adapting to any unmanned vehicle and obtaining the necessary measurements, and thus, according to Javier Lara, project leader, “it brings new technologies into contact with the world of construction, as it combines virtual and augmented reality with what is executed at the site”.
Its capacity in construction has already been put to the test and has been proven thanks to three main characteristics. First of all, it makes it possible to develop a multisensory in-motion-scanning and high-resolution-image platform.
The information collected helps us to be more ready to address any needs faster and more efficiently. Javier Mateo, innovation specialist, explained one of the applications. “For example, in emergency situations inside tunnels, Pandora enables us to fly inside by means of drones and use them to obtain information and make decisions without risking any lives”.
Secondly, Pandora enables an autonomous navigation system to be developed for areas where the position of the recording equipment is unknown, due to an absence of GPS satellite signal reception. Thirdly and finally, it permits the development of software applications based on virtual and augmented reality.
These applications, which include the generation of new virtual scenarios with the incorporation of constructive elements, travel through the generated environment without needing to be in the action zone itself. “Its ability to gather a point cloud is what generates a digital model for us to use to build these models”, added Marcelo Onsurbe, head of the Topology and Layout area.
This construction-based technological improvement project coordinated by Sacyr Ingeniería e Infraestructuras has been developed in collaboration with two leading enterprises in their respective sectors. “We have been able to work with Atyges, a company specialising in developing drones, and with Aplitop, which specialises in developing topographical applications of application in civil engineering work”, explained Antonio Ramírez, Innovation and Knowledge Manager.
Also participating in the company's project are two research centres, the Center for Advanced Aerospace Technologies (CATEC, Centro Avanzado de Tecnologías Aeroespaciales), which focuses on aerial platforms for drones, and Universidad de Oviedo, specialising in point cloud filtering techniques. At Sacyr, we are committed to strategic alliances in order to add value to innovative projects such as Pandora.
