assessments screen projects to determine whether further investigation is required, while detailed risk assessments use project-specific archive research and a semi-quantitative risk model to characterise hazards to ground works. Impartial Assessments also conducts peer reviews of third-party risk assessments to provide a technical second opinion on methodology and conclusions. Its services are intended for clients in construction, engineering and environmental sectors who must consider explosive ordnance as part of wider health and safety and project planning obligations.
