Open innovation tested in the field

To support the developers of innovative solutions in their deployment, Leonard facilitates their connection with the VINCI ecosystem in order to test their solutions in real conditions and to work on their optimisation with real users. Here is a look at three of these experiments.

Solution 1 :

LEONARD SUPPORT: Catalyst 2022 programme.


The work carried out by our teams on the maintenance site of the Nantes-Brest canal takes place on former towpaths used by walkers and cyclists. Although access to the worksite is blocked off during operations, local residents and walkers still venture near the machines, increasing the risk of collision and requiring increased vigilance from the teams.


The LifeGuard solution developed by uses artificial intelligence to detect and prevent the risk of collision between machines and pedestrians and to secure the environments where they cross. An LCD screen, linked to a camera, allows the driver to follow the perimeter of his intervention by being alerted to the approach of a pedestrian. A loudspeaker system warns the pedestrian to move away.


The solution is very easy to use thanks to a software to set the safety distances. The loudspeaker warning and the camera assistance allow the operator to focus on his tasks and the pedestrian to move away spontaneously. The cost/benefit ratio is clearly interesting.


Add a loudspeaker near each camera so that pedestrians can hear the warning message perfectly, whatever their position.


The recognition of the pedestrian by the AI (which makes the difference with an obstacle) and the calibration of the detection zones.

Solution 2 : R.Used

LEONARD SUPPORT : intrapreneurs 2022 programme.


To host the ephemeral pavilion for the “Aqua Mater” exhibition at La Défense, we had to install a double base made of concrete and polystyrene. When the installation was dismantled, these two bases were destined for reuse or destruction. But finding an opportunity for reuse is only done informally, often by word of mouth. Most of the dismantled site elements go to the skip.


R.used functions as VINCI’s internal “Leboncoin”, a marketplace for putting people in touch with each other to facilitate the re-use of materials, equipment and resources between worksites. R.used thus makes it possible to extend the lifespan of
of materials while saving money.


I am completely convinced by the experience: my concrete slabs are used on a new Parisian site, and my polystyrene slabs are reused as backfill on another project. R.used encourages the development of new reflexes: rather than going through the systematic mechanism of purchasing, thinking about reuse is made easier. Everything is integrated into the application, from the search and publication to the issuing of delivery notes.


Put forward lists of advertisements by trade or by profile to give ideas even before the need is expressed.


The ease of making contact and a user process fully integrated into the application.

Solution 3 : Machine26

Tested by Nordahl Grenier, materials manager, Eurovia Allemagne

LEONARD SUPPORT : SEED 2022 programme.

To help our field teams, especially our equipment managers, in their inspection and management of their machinery, and then to make it available internally or sell it externally.
available internally or sell them externally. Until now, everything was done through heterogeneous forms, which limited the scope of such an approach, and most of our resales were done through brokers.

Machine26 is a platform for the resale of used machines. By offering integrated software, it facilitates the evaluation of machines and the distribution of advertisements, and makes it possible to build a network of external dealers
within a standardised and secure procurement process.

We contacted Machine26 in 2020 for a first test on the digitalisation of our machine valuation process. Their platform is very didactic, very user-friendly, and standardisation makes it possible to homogenise
to facilitate their distribution. Convinced by the solution, we have started to calibrate our organisation accordingly, from local to regional and soon to global level. In two years, we have already made more than 1 million euros worth of sales through the platform. The more it is deployed, the more buyers we will be able to attract.

We are working with Machine26 on the phase of making the machines available internally and a wider deployment to all our European countries.

Control of our marketplace from start to finish, particularly with regard to buyer compliance criteria and ease of reading and posting ads.
