  • Natural Hazard Assessment.

    A natural hazard assessment is a systematic and comprehensive evaluation of potential natural hazards that may affect a specific area. Natural hazards refer to geophysical, meteorological, hydrological, and climatological events that have the potential to cause harm. This can include earthquakes, floods, hurricanes, tornadoes, landslides, tsunamis, droughts, and wildfires.

  • Earthworks Monitoring + Certification.

    Earthworks monitoring, also known as geotechnical or ground movement monitoring, is a process that involves the systematic observation and measurement of changes in the earth's surface or ground conditions. It is commonly used in construction, mining, civil engineering projects, and other activities that involve significant alterations to the landscape. The primary objective of earthworks monitoring is to assess the stability and safety of the ground during and after construction or excavation activities.
