Ever since its introduction at the beginning of 2004, we have been consistently using the QM-System (quality management of the planning and control of the construction project's implementation) in accordance with the regulations DIN ISO 9001/2000. The QM manual was produced and on July 9th, 2004 Mr. Dierk Pfränger successfully completed the training and became a certified internal auditor.

The TU Arnstadt joined as counseling partner and after the certification, we won the TÜV Thuringia certificate. The audit to get the certification was carried out on December 3rd, 2004 and on the certified auditor's recommendation we were issued the certification.

Since it was established in September 2004, the quality management system has been running and been constantly put into practice.
