Aker Wirth, a leading supplier to the tunnelling industry for more than a century, was recently audited by the accredited certification body DNV. As a result, the company was granted both re-certification in occupational health and safety under OHSAS 18001:2007 and initial certification in environmental protection under ISO 14001:2004. Aker Wirth is aware that customers are demanding high levels of reliability and sustainability, and that independent, verifiable certification is essential proof of the efforts made throughout their organization.
