Service Offerings


It is GHD’s belief that our employees are our most valuable resource and that they deserve to practice their profession in a safe working environment.  Our goal is to be one brand, renowned for client service and a culture of safety. To achieve this goal, we are committed to working cooperatively on the priorities and actions identified in the five year GHD HSE Strategic Plan – SAFE You, SAFE Me, SAFE GHD. By regularly reviewing our achievements against the HSE Strategy’s goals, we will continually improve our safety performance.


GHD's Quality Management System was first certified to ISO 9001 in February 1993. Since that time it has evolved and improved as GHD has grown and expanded. What began as a state specific Quality Assurance System within Australia has grown into a global Quality Management System which is supported in GHD offices in Asia, the Middle East, North and South America, Europe and the Pacific region.
