New certification

The SONNTAG quality and environmental management system was successfully certified by the TÜV in accordance with DIN ISO 9001 and ISO 14001. 

The name SONNTAG is synonymous with construction quality and expertise. The satisfaction and confidence of our customers is based on the premise that we provide our services on schedule and in the quality agreed. We aim to underline this with our QM system. With the introduction of our environmental management system, we succeeded in identifying and evaluate any relevant environmental aspects throughout our organisation and preventing their potential negative impact on the environment as a whole, pre-emptively and sustainably. Today, with an extensive portfolio of certificates, we are proud to be able to demonstrate how our corporate policy, which focuses on quality, environmental issues and occupational safety, is having a sustainable, positive impact on our entire organisation.
