Irrespective of any certifications, we have demonstrated in hundreds of projects that we are able to realize and maintain our technical competences in all domains of our portfolio.

We are proud of having been awarded several certifications proving our proficiency and quality-conscious work:

  • The Klett Ingenieur GmbH is internally using an up-to-date QM-System that had been awarded the DIN-ISO 9001 according to standards of the German Technical Control Board in the years of 1999-2002.
  • According to our employees’ certifications, we are allowed to plan fire detection systems of DIN 14675 standards, to supervise their installation and to give energy consulting if needed.
