Our Understanding of Sustainability

As Dorsch Gruppe, we shape sustainable living spaces with our subsidiaries worldwide. In a world that becomes more and more urbanized, the infrastructure sector plays a key role in fighting climate change. Therefore, we see it as our task to actively advocate for more sustainability in the consulting engineering industry.

We define the term sustainability as the integration of ecological, social and economic factors in all our activities. At the same time, we ensure that the needs of all our stakeholders are considered. As an industry pioneer, we see sustainability as a core element of our vision:

"We are shaping tomorrow's infrastructure to meet global needs."

Our aspiration is to create innovative, holistic and resource-efficient value for all stakeholders and to promote sustainable social development. We therefore align our processes for the long term, putting sustainability at the heart of everything we do. Our core business is represented by high-quality, independent and sustainable engineering and planning work. We use our entrepreneurial and professional knowledge to provide our customers with concrete and sustainable solutions that avoid, mitigate and compensate for any environmental risks. With our technical expertise and planning experience, our experts can identify risks to the environment at an early stage and take them into account in a targeted manner.

Our quality culture

Everyone talks about quality - but what exactly does that mean?

The quality management system of Dorsch Gruppe serves as a compass for orientation and creates transparency. Together with the principles for sustainable corporate management, our quality management forms the basis for the Dorsch management system.

The ultimate goal of our management system is to ensure that our customers are satisfied with our provided planning, construction supervision and consulting services in the long run. To achieve this, the Dorsch management coordinates and monitors the compliance with the strategic measures and regularly makes necessary corrections. It supports the employees on their way to the goal of ensuring that the requirements for our services agreed upon with the customers are met. For our employees to meet these requirements, the greatest possible importance is attached to the internal as well as external transfer of knowledge. The aim is to have the best possible trained and experienced employees in our respective areas of competence.

Corporate management coordinates and monitors compliance with strategic measures and regularly makes any necessary corrections. Only together with our employees we can achieve this goal. The continuous development of the Dorsch Management System is a central concern for us. Together we scrutinize the processes on the way to our service and improve them continuously.

This quality management system pursues the following central points, among others:

  • Sustainability: we design infrastructure for future generations considering ecological, social and economic factors.
