Tour Alto: an enormous security puzzle

The media remains fond of trendy keywords, and “smart city” has been one of them for some time. New projects are emerging all around the world and even nearby, with the new towers springing up at La Défense.

As such, Tour Alto, a project launched by Bouygues Construction, located near Tour First, with a height of 231 meters (the tallest in France) and still under construction, promises to integrate all the latest technologies.

It’s an opportunity to take stock of the security of these workplaces which bring together several thousand employees and sometimes numerous companies.


1. How to manage security and the flow of people and materials

Even if we love the idea of an intelligent and hyper-connected tower, our collective memory cannot erase some of the images and the fear they’ve created.

Securing data and people, therefore, remains a major challenge before even beginning to think about improving performance. It goes without saying that the merging of data is what enables the analysis and creation of new services.

Nicolas Séailles is the construction engineer at Bouygues Construction, and is in charge of the technical trades for Tour Alto. He explains:

Up until now, the trades worked in silos. The idea is to show them that data should encourage them not only to develop their apps by function, but also to have them communicate between themselves in order for them to be optimized. Elevator management, entry control, lighting and access to catering services can all benefit from the exchange of information put forth by users. As such, we can create value and continuously improve the services offered by the building. Artificial intelligence will allow us to define use cases and enrich each of these services.”


2. How to secure the data used in the real-time development of services adapted to each other’s uses?

Sharing data remains a voluntary and personal initiative in most cases. The tower’s inhabitants should have complete faith in the processing and storage of data by the various operators involved in the real estate project.

Nicolas also points out that “two things are very important with respect to data: the protection and security of personal data, for which there are now ANSSI and RGPD certifications. Technology makes it possible to avoid entering the dark side…to avoid having a “Big Brother” effect. The objective remains for people to share their data willingly.


3. How to master access and communication

Since individuals have very quickly adopted these recent technological changes, they must be protected against any possible breaches, and a building can’t be truly intelligent without using the fiercely protected data it generates.

What’s different today is that 100% of people have smartphones, and that all intelligence centers around them. For example, we use our fingerprints and our faces so we can know exactly who’s behind the phone and what his or her behavior is. Ideally, if I leave my office to go to the break room, the robot who delivers my meals will receive this information and will come to find me in the right place. All flows of people and associated services will thus be optimized through these new use cases,” Nicolas concludes.

Smart building projects oriented toward users offer better fluidity and greater ease of use. They also take into account the risks associated with people’s mobility and the increased communication of data associated with it.
