Patrick Oconnor Assessing The Situation 3

Health & Safety

Safety is our 1st consideration at Diona. It is our primary goal to provide safe and healthy work environments for all employees and subcontractors.

The Diona Safety Management System is certified to AS/NZS 4801:2001 and is built around the continuous improvement of our safety policies, processes and procedures. All employees and subcontractors are Diona safety inducted and receive ongoing training to ensure they know and understand their obligations and can personally support safe work practices on all of our sites and offices.

At Diona, health and safety goes beyond having procedures and processes in place. We believe it’s about creating a culture of care. Care for self, care for teammates, care for the community, and care for the environment. Through this culture of care, our people are empowered to take the necessary steps to ensure their workplaces are safe and healthy so that everyone goes home unharmed at the end of every day.

By their very nature, our projects can have a substantial impact on the environment. So we take our environmental responsibilities very seriously.

Our proven Environmental Management System (EMS) is certified to ISO 14001:2015. The system takes an integrated approach, with multiple methods and tools at our disposal to ensure all of our work practices minimise, as much as possible, any negative effects on the environment. Everything from erosion and sedimentation control methods, to habitat protection practices, are monitored, reviewed and adapted to meet site-specific parameters, so we always deliver the best possible solution.

Diona has an outstanding record in environmental management. But we are not resting on our laurels. New projects create new challenges, so we are constantly developing new techniques and approaches.

Diona delivers first-class projects that we are proud to stand by. We have earned our reputation in the highly competitive infrastructure industry by insisting on excellence in our design, construction and project management.

The key to the quality of our work is Diona's Integrated Management System (DIMS), with ISO 9001:2015 certification. Coupled with our decades of experience, DIMS allows us to easily determine the best approach for achieving a quality outcome, on time and to budget.

Our Quality Management System allows us to regularly measure, review, analyse and improve our business processes, project delivery, maintenance, and management methods. This ensures we make the most of every opportunity to improve our client service and the quality of our work.
