NVAQ has extensive experience delivering air quality consulting across construction, civil infrastructure, tunnelling, mining, demolition, remediation and industrial environments. We regularly support projects involving high-risk airborne contaminants generated during cutting, grinding, excavation, blasting, crushing and material handling activities.

Our work assists persons conducting a business or undertaking (PCBUs) to identify exposure risks, assess worker exposure and implement appropriate control measures in line with WHS Regulations and applicable Codes of Practice.
