Do your favourite sounds come out of the Bluetooth speakers? Turn lights on or off throughout the house with a single click?

Together with your team, you ensure that the power and data in a building arrive exactly where they are needed. To do this, you lay the pipes for the cables in the building shell and set the boxes for the installation of apparatus and devices. During the finishing work inside, you then pull the cables through the pipes, and install and connect the required appliances, equipment, sockets and switches. In the event of faults, you ensure the comfort that users are accustomed to is restored quickly.
