Impressive: the new dm-dialogicum in Karlsruhe, fitted with door, window and safety technology from GEZE

The new headquarters of German health and beauty store chain dm in Karlsruhe offers space for more than 1,800 employees and guests. As the name dm-dialogicum suggests, the building also offers plenty of space for communication. Interior design, working atmosphere, sustainability and safety were therefore key topics in its design and construction. GEZE accompanied this ambitious new-build project from the outset, offering specialist advice and reliable project management as well as installing modern door, window and safety technologies commensurate with the high standards demanded by the architects, planners and building contractors.

Welcome to the dm-dialogicum – GEZE revolving doors shape the main entrance

The entrance to any building makes an impression – and first impressions need to be positive. Generously sized GEZE revolving doors shape the entrance to the new dm company headquarters.

The TSA 325 NT revolving door system  provides smooth, draught-free access all day long, ensuring that the 1,800 employees and visitors can enter and leave the building quickly and conveniently, even during peak hours.

Escape routes: a key aspect of building security

The dm-dialogicum offers space for over 1,800 employees and visitors. Safe emergency escape and rescue routes are essential, particularly with so many people in the building. The GEZE emergency exit system guides people out of the building quickly and safely. An electric locking system in compliance with the EltVTR – the German standard for electric locking systems in doors on emergency escape routes – has been installed to ensure that escape and rescue routes can be used in case of emergency, but are otherwise not accessible without authorisation.

Installing FTV 320 escape door locks increased the locking force of doors on escape routes, thereby also enhancing overall building safety. The locks’ integrated feedback contacts allow the doors to be monitored reliably, while integrated sabotage monitoring secures the lock against manipulation.

Seamless communication ensured by core contact partners at GEZE

A large-scale project such as the dm-dialogicum involves a number of different technical crews. It is crucial that the project managers have an overview of current progress and can rely on everyone involved. The dm project managers had a consistent core of contact partners at GEZE responsible for all technical crews, which ensured seamless communication on site. Consequently, expert advice was always on hand, from the project planning phase to installation and through to the after sales service – a decisive factor in the success of the dialogicum project.
