ELISIR project: eco-seismic building regeneration 4.0

Gexcel will provide its own technologies in 3D mapping, fast 3D digitalization, and BIM model update within the ELISIR project. These technologies are essential to drastically reduce costs and times of surveying activities and to assess in real-time the as-built conditions of a building.

ELISIR stands for Energy, Life Styled & Seismic Innovation for Regenerated Buildings and it aims at exploiting the potential of digitization in order to create a very personalized product-service to be offered on the market of the existing building heritage focused on seismic improvement and energy efficiency in a "smart living" way, developing a real "Built in Italy". The research project has been launched last November with a research call funded by the Lombardy Region and will end in May 2019.


Gexcel participates in the project, along with other important partners, using the HERON technology for the rapid survey of buildings, for the as-built data acquisition in the form of a point cloud, and will further develop the product adding the possibility of collecting camera data. Schneider will contribute by developing appropriate sensors for energy analysis, a platform for collecting, storing and processing data and validating them. Valsir will undertake the development of hydraulic connections leveraged by sensors, to monitor all the water consumption of the various users. H&D will craft appropriate financial products to provide "the business model and a brand capable of spreading and introducing innovation in the supply chain" with possible "consequences on foreign markets that will be investigated together with the partners involved". Delta Phoenix will fine-tune the energy seismic plaster. The development of smart windows will be taken care by Italserramenti, which will experiment products with a high degree of automation and intelligence, able to adapt to users' needs and independently manage environmental comfort.

The concept of the project was born at the DICATAM headquarters in the University of Brescia, on the initiative of Angelo Ciribini, one of the leading experts in Building Information Modeling (BIM) and digitization in construction. The second university involved is the Milan Polytechnic, with the Abc department - Architecture, Engineering and the built environment, and in particular with the operating units "Building envelope engineering group" and "Sustainable building process management group". Find more...

KEYWORDS: Classification Mapping | JRC 3D Reconstructor | 3D Laser Scanner | Heritage | Architectural

Assignment carried out in 2016 and 2017 for the underground part, commissioned by the Public Authority of San Gimignano (Siena) to the "RTP Borromini" group, a multidisciplinary professional team composed of specialists in architecture, engineering, restoration, and archeology. The STUDIO ASSOCIATO PERIGEO was involved for the topographic and laser scanners survey. The complicated geometries detected with the 3D laser scanner, together with the accurate topographic survey, were then used for all the subsequent phases of detail analysis and output of a unique georeferenced system. Thanks to the data processing software JRC 3D Reconstructor, it was possible to collect and share 3D outputs from laser scanner scans and an in-depth evaluation of underground constructions of historical and anthropological interest.

CASE STUDY — Fast 3D mapping and "as built - as designed" analysis of a Le Corbusier style building in Italy

A pleasant Le Corbusier style building has been surveyed with HERON to analyze the structure realization and study how its shape could be inserted in the urban context.

Location Studio Santi Castel Goffredo, ItalyLocation Studio Santi Castel Goffredo, Italy

  • Location: Studio di Architettura e Ingegneria "Arnaldo Santi" of Castel Goffredo (North Italy)
  • Application: by Topotek Srl
  • Industry: Construction
  • Surveying system: HERON AC-1 Color

HERON has been able to impressively respond to the two main specific customer's needs:
  1. Check the correspondences between the existing BIM project (as designed) and the geometric results of the as built construction process.
  2. Carry on fast surveying of large areas, getting results almost in real time in order to quickly pass to a pre-projects analysis and operate in construction sites affected by fast changes.


The entire survey of the indoor/outdoor parts of the site took about 10 minutes.

After only 20 minutes of elaboration, a scaled plan view of the site was available and ready to be visualized in a CAD environment. The point cloud, obtained from HERON, has been moved into JRC 3D Reconstructor software where the BIM model of the building has been compared with the HERON point cloud model.

The results show the good correspondence (2-3 cm of differences measured) between the BIM model and the reality. The experience has shown the high productivity and accuracy (tested with few control points) of the HERON SLAM approach thanks to a high resolution 32 lines Velodyne rotating laser scanner and a robust patented "global optimization" approach.

In order to insert the 3D survey of the building within a new survey of the city center, the HERON automatic self localization function has been used. The HERON post processed point cloud model of the building was loaded inside HERON that used it as reference model. Coming back to the site some days after the first acquisition, HERON was able to automatically recognize its position respect to the point cloud reference model and start mapping the city center. In this way, the 3D fast mapping model of the town has been easily joined to the 3D model of the building, without using targets or reference points.

The town survey required 3 hours, at a normal walking speed, without care of sky visibility and without need local calibration. Stairs, trees, different geometries are not a problem for HERON and the 3D survey data are directly visible, in real time, on the touch screen control unit provided with the instrument. The first result of the HERON survey is the so called "fast blue print image": an easy result that can be immediately imported in a CAD software without any other 3D point cloud data processing.

  • HERON can strongly support the construction sites in fast "as built - as designed" analysis, where a 2-3 cm accuracy can be acceptable.
  • The automatic geo-localization capability can introduce the innovative fast and frequent 3D models updating services, carried on by operators with basic knowledge in surveying and geolocalization.
