In August, the headquarters was installed on the Ecolint construction site. This will house the construction management and provide changing rooms and a refectory for the subcontractors.

The video also shows the start of the installation of the Canadian well. Thanks to pipes buried in the ground, this air circuit makes it possible to use the difference in temperature of the ground to cool the air in summer and to heat it in winter. This energy recovery reduces heating consumption.

Steiner’s teams have also started to build the foundation for the connecting tunnel that will link the main building to the Ecolint extension.
