Our quality commitment, secured by an integrated management system.

We are only satisfied when our customers are satisfied. Meeting our customers’ needs, fulfilling their wishes and building something sustainable for them – that’s what we aspire to achieve. Today, any company hoping to survive and succeed over the long term must embrace its responsibility in a wide range of fields: responsibility for people and the environment on the one hand and the efficiency of its management processes on the other. Working to comprehensively assure compliance with quality requirements is therefore a top priority at PORR and is clearly regulated in our Corporate Policy.

We document every work step in process flows and work instructions in order to uphold our high standards. At the same time, we are mindful of the impact our construction methods have on the environment. To ensure quality, we implement internal quality assurance procedures during construction and when signing off each subsection.

Transparency is important to us.

The efficiency of our integrated management system has been confirmed by independent certification company Quality Austria.

The entire PORR Group is currently certified to the following standards:

  • ISO 9001:2015 . Quality Management System
  • ISO 14001:2015 . Environmental Management System
  • ISO 45001:2015 . Occupational Health and Safety Management System
  • ISO 50001:2018 . Energy Management System

ISO 9001:2015 . Quality Management System

Quality management provides a continuous and comprehensive overview of all measures to support process planning, control and optimisation. Continuously developing our Quality Management System is a crucial part of our day-to-day work and our company philosophy, with the ultimate aim of satisfying our customers.

ISO 14001:2015 . Environmental Management System

PORR approaches environmental aspects from the perspective of preserving value. Responsible use of natural resources, a clear commitment to environmental protection and a value-driven approach are key pillars of our sustainability strategy.  Our Environmental Management System successfully regulates all responsibilities, processes, requirements and behaviours related to environmental protection.

ISO 45001: 2015 . Occupational Health and Safety Management System

Occupational health and safety has been a top priority for PORR ever since our company was established. PORR is acutely aware of its responsibility to promote its employees’ health and protect them from hazards in their daily work. With this in mind, we regard an effective Occupational Health and Safety Management System as essential.

ISO 50001:2018 . Energy Management System

We are committed to using our resources sustainably. By turning to alternative drive systems and energy sources, we are striving to improve our energy efficiency and reduce pollutant emissions. We also require each business unit to systematically record their environmental impacts and design and implement improvements.

Certificates for safety / prequalifications

In addition to certification to ISO 14001:2015, the safety management system also complies with the requirements of SCCP:2011, because here at PORR safety and health have top priority.

Other independent companies, such as Deutsche Bahn AG, also confirm our skills and actions through prequalifications and special recognition
