A fundamental commitment to Health and Safety is a key feature of our culture, identity and values. We strive, with our employees and partners, throughout all our facilities, operational worksites and offices, to achieve the very highest safety standards.

From the very beginning of the company in 1957, we introduced an HSE management system with clear objectives in terms of the results we wanted to achieve. And more recently, for almost a decade, we have implemented a company-wide process intended to ensure we have a deeply embedded and sustainable safety culture.
At PREZIOSO Linjebygg, we all know that an integrated safety culture goes beyond the implementation of a classical and directive top‐down set of safety policies and procedures. It is the result of a holistic approach to safety which incorporates everyone within the organisation, in every country where we operate, from top management to field operators and support personnel.

The launch of our Safety Golden Rules in 2014 was part of this continuous programme to embed safety within our culture.

We take a responsible and ethical approach to the governance of the group, having internal procedures which:

  • adhere to the guidelines published by the UK Ministry of Justice in order to prevent bribery

Quality through Performance
To accompany our significant growth over the last few years and to keep on improving customer satisfaction, we have implemented an integrated management system through a strong risk management approach, reliable processes and improved performance.
