Certificates and seals of approval

Selected certifications of the Hering Group

This overview is just a rough sample of our certificates. Additional certificates are available on request.

HERING sustainability

At HERING, we see ourselves as pioneers in the field of sustainability. As early as 1996, we were the first construction company in Germany to obtain EMAS certification. Every three years, we publish an environmental statement documenting our goals and how we have achieved them. Actually, for the first time, we published a sustainability report with an integrated environmental statement in accordance with EMAS - a logical next step in view of our ecological and social responsibility. It documents how we deal internally and externally with the issues that are essential to our future viability.

EcoVadis - Business Sustainability Rating

HERING had its sustainability performance evaluated in 2023 by the Ecovadis rating agency and received the "Gold" award. Ecovadis operates a collaborative platform that provides CSR ratings of suppliers for global supply chains.

QM – Quality management

Quality Management Standard ISO 9001 is the most widely-used and significant standard in the field of quality management on both a national and international level. Certification forms the basis for the continuous improvement process. The certificate is proof of implemented quality management of the HERING company group, in accordance with DIN EN ISO 9001, and is subject to regular monitoring by GüteZert GmbH.

HPQ certification for the production of modular platforms for the Deutsche Bahn AG

HERING Bau GmbH & Co. KG was awarded the ‘Herstellerbezogene Produktqualifikation’ (‘Manufacturer-related Product Qualification’) certification that allows it to manufacture modular platform systems made with prefabricated reinforced-concrete parts following the successful appraisal by the Deutsche Bahn. This certification is required before companies are allowed to manufacture prefabricated platforms in accordance with DB Station&Service AG’s current specifications.

DIN Certco certificate – barrier-free construction

Due to the demographic change, accessibility in public areas is becoming an increasingly important issue. All WC facilities installed by HERING bear DIN Certco certification, and are accessible in accordance with Standard DIN 18040. For many years, these provisions have been the basis for planning, as well as for constructional and structural implementation.

Conformity certifications from Güteschutz Beton NRW e.V.

Güteschutz Beton NRW monitors and certifies prefabricated concrete elements. The certificates confirm that the results of the external monitoring conform to the general building approval. The certificates of compliance apply to modula® railway platform systems, and the thin-walled betoShell® concrete façades.

CrefoZert for excellent creditworthiness

CrefoZert is awarded for good business practices that have been consistently demonstrated to date and is also a good indicator for future business development. A certified company receives an entry in Creditreform’s credit rating that reflects its good payment record and positive prospects.
