About us

DMS is a medium-sized family business with a focus on building, factory and process automation. We advise, plan, deliver, build, install, commission, maintain, in short: we do everything to ensure that our customers enjoy the automation of their buildings.

We see constant innovation and quality as the basis of our success. That is why we invest continuously in the training and further education of our employees and in the new and further development of our products and system solutions. Well-known, internationally active companies from various industries rely on our knowledge and trust our expertise in technology and project management.

History and future

The company was founded in 1981 as Technisches Büro Werner Hössl in Gerlingen. In 1997, the company was converted from a limited liability company into a stock corporation. In this context, the management board passed on to the next generation. In the business year 2020, about 60 engineers, technicians and computer scientists achieved a turnover of around EUR 25 million.

The future of the construction industry is digital. Since its foundation, DMS has been a digital company. We have carried the “digital” in our name for 40 years. We recognise a multitude of chances and opportunities in digitalisation. At present, we are actively exploring IoT, BIM, Cloud Services, Predictive Control strategies and AI.

We have completed the transition from traditional buildings to automated buildings with many customers and now want to create truly smart buildings based on predictive services and AI. Buildings that can detect changes in use and optimise themselves on this basis, thereby creating genuine added value for owners, users and operators.

We see technology as a means to make buildings better and also to achieve efficiency and sustainability goals that are desirable from a socio-political perspective – that's what we're working for!


Our employees are special in many respects: they are particularly reliable, particularly critical but above all particularly motivated and interested in designing meaningful and high-quality solutions for the tasks of our customers. Our employees are important to us – so important that we gave them a stake in our company more than 20 years ago. We demand a lot from them because we also demand a lot from ourselves – in the interest of our customers.

Our values

As a value-oriented family business, we strive to harmonise economic, social and ecological interests. Mutual respect and fairness in dealing with each other and with our business partners form the basis of our corporate culture. We always act in accordance with the applicable laws, regulations and other rules. Through our sustainable corporate management, we distinguish ourselves as a long-term reliable partner.


Experience is valuable. This applies to all industries. For DDC technology and building automation, this applies even more! Experience is important, but at least as important is the permanent curiosity for new, better solutions. This is the field of tension in which we operate, and we try to create a basis through lived best practice and the permanent examination of the latest technology and methods, which allows us to develop innovative, contemporary and sustainable solutions.


The satisfaction of our customers is the mirror for our quality standards. Products, services, processes and activities are constantly reviewed, questioned and, if necessary, improved. Our quality management system is certified by TÜV according to DIN EN ISO 9001:2015. We have received several awards from our customers in recent years, including the "Business Excellence" category from SIEMENS and the "Global Supplier Award" from ROBERT BOSCH GMBH.


We efficiently provide the services for our customers in excellent quality. When advising our customers, we focus on the best solution for them. Together with our partners, we have around 200 DDC/BMS specialists at our disposal for the various project components. We are proficient in the entire range of building automation services and can also provide solutions for complex problems from a single source.


You can rely on us. Whether planning, construction or service, our employees put a great deal of experience and passion into their work. We communicate swiftly and honestly, and stand by what we communicate – this is extremely important to us because we see it as the basis for trusting and constructive business relationships.


We rely on partnership: with our customers, with our suppliers and with our employees. We create scope for creativity, responsibility and innovation. We see this as the basis for high-quality solutions, satisfied customers and thus for the long-term success of our company.
