Our services support construction, property, industrial, government, health care, education, utilities and waste-sector clients to identify hazards, manage compliance obligations and protect workers, occupants and the environment. We provide occupational hygiene and workplace monitoring services, including exposure assessments, indoor air quality assessments, noise monitoring and personal exposure monitoring for airborne contaminants and hazardous substances. Opterra also undertakes hazardous building materials assessments, including asbestos, lead-based paint, synthetic mineral fibre and other hazardous materials, as well as mould impact assessments, post-remediation validation, hazardous chemical and dangerous goods assessments, clandestine laboratory assessments, environmental risk assessments, environmental management plans and waste classification support. Our approach combines technical expertise, clear communication and fit-for-purpose reporting to help clients understand risks and implement practical control measures. Where laboratory analysis is required, Opterra uses accredited laboratories and quality-controlled procedures to support reliable, defensible outcomes.
