Building in the existing stock

Our promise to you:

Deliver quality. Underline individuality. Equip an object with inner values. Cost certainty. On time. Flexible. Reliable. For the optimal use of commercial space. Without ifs and buts.

Building in existing structures is always a bit of a journey into the unknown. What awaits us under false floors, in old shafts, under wall coatings? Mostly exciting building history, sometimes nasty surprises.

Integrating modern technology into old structures is particularly challenging:
The building climate, energy efficiency, the recyclability of building materials and the clever unbundling of technology and building play an important role. Under the leadership of specialized construction managers, with the support of selected partner companies and, last but not least, through the execution work of our skilled workers – we would like to be your strong partner in the realization of your construction project.

We provide you with all services from a single source.

Revitalization means redesigning a building structure in such a way that it can once again be used in a contemporary manner. Revitalization is more than just redevelopment. Old real estate shines in new splendor.

The restoration of historic structures requires great sensitivity and professional skill. Here, the experts of GTW Bauwert’s revitalization department help old buildings to shine again.

Light current technology

Hazard alarm systems BMA / SAA and low current systems in general.

When a fire starts, every second counts to save lives, preserve property and save businesses from possible “ruin”!

The central pillars of preventive fire protection are therefore early fire detection, limiting the fire to a fire compartment and timely alerting of building occupants in the event of a fire.

Fire detection is necessary in all areas where people are present: industrial buildings, office buildings, hotels, schools, kindergartens, hospitals and retirement homes.

As a DIN 14675 certified company, we are available for consulting, installation and maintenance of professional fire alarm systems and voice alarm systems.

We are also the right partner for you in other areas of low-current technology, such as emergency call systems for the disabled, IT networks, access controls, intercoms, video systems and much more.
