We strive to ensure the safety of our workers, subcontractors, site visitors, and the public is maintained for the duration of each project, that environmental impacts are minimised, and that we remain compliant with all applicable legislation, as well as regulatory and statutory obligations. 

Project specific HSEQ plans are prepared and detail how DEMEX will comply with its obligations and meet company HSEQ goals and objectives during project delivery. These detailed plans include:

  • Recognition and compliance with relevant legislation and regulatory and statutory obligations

  • ISO 14001:2015 – Environmental Management Systems – Requirements with Guidance for use (Certificate number: 418081E)Due diligence and duty of care

  • Environmental management

  • Quality management.

In addition to our Health and Safety Policy, together with project specific HSEQ plans, we also operate under a formalised Hazard Identification, Risk Assessment and Control procedure that complies with the stringent conditions defined by the Office of the Federal Safety Commissioner’s Australian Government Building and Construction WHS Accreditation Scheme (FSC Accreditation). We routinely implement a range of measures to identify, assess, and control hazards in accordance with this procedure, and record all incidents, near misses, and non-conformances in a company register, which facilities the tracking and trend analysis of incident outcomes.

In terms of incident management, incident investigations are completed to identify the root cause of the incident and to identify the appropriate corrective / preventive actions to be adopted. Following a suitable time period, the effectiveness of the adopted control measures are reviewed to assess the overall effectiveness and to ensure no inadvertent hazards have been introduced as a result. Where required Safety Alerts are issued to staff.

This approach to HSEQ provides confidence to clients that our commitment to safety is reflected in practical application of measures that underpin safe project delivery.

DriveAbout Workforce 

In recognition of vehicle related incidents as a major killer in the workplace, in 2022 DEMEX formally committed to a work health and safety initiative to embed a culture of road safety into our organisation in response to an identified need to address driver behaviours as a workplace health and safety issue. Through our research into available training, we identified DriveAbout Workforce, an Australian road safety and road rules education program.

DriveAbout Workforce is an award-winning Australian road rules and road safety refresher, which uses EdTech to deliver approximately 90 minutes of visually rich road rules and road safety education via a secure online learning management system (LMS). The training complements and supports existing driver education resources through its alignment to the National Road Safety Strategy 2021-30, and the Towards Zero and Fatal Five campaigns. It is scalable, cost effective, and suitable for culturally and linguistically diverse audiences.

Every DEMEX employee completed the training when the program was first implemented in 2022 and going forward, will complete an annual refresher. All new employees are required to complete the training as part of their onboarding induction, while employees who receive driving infringements in DEMEX vehicles are required to repeat modules relating to the infringement.
