Perth’s seismic landscape, while moderate, is shaped by the Darling Fault and deep sedimentary basins that amplify ground motion. Local compliance follows AS 1170.4, requiring site-specific assessments that account for the Swan Coastal Plain’s soft soils. Our category addresses this through targeted soil liquefaction analysis, evaluating cyclic softening in saturated sands near the Swan River, and detailed seismic microzonation to map varying hazard levels across the metro area.
These investigations are critical for high-rise structures in the CBD, essential infrastructure, and port facilities in Fremantle. For projects demanding enhanced resilience, we integrate base isolation seismic design to decouple structures from ground movement. Every study delivers defensible ground models that align with Australian Standards and safeguard Perth’s built environment.
