Seismic assessment in Bunbury addresses the southwest Australia seismicity profile, where moderate intraplate events and the proximity to the Darling Fault demand rigorous site characterisation. Our approach integrates AS 1170.4 earthquake actions with local Perth Basin geology, beginning with soil liquefaction analysis to evaluate saturated sands and silts that may lose strength during ground shaking. For critical structures, we extend the scope with seismic microzonation to map amplification hazards across variable substrates, ensuring compliance with Australian Standards and local council requirements.
Typical projects requiring seismic input include multi-storey commercial buildings, bridges, and industrial facilities on reclaimed or alluvial ground. For essential infrastructure where operational continuity is paramount, base isolation seismic design provides a performance-based solution that decouples the superstructure from ground motion. These services collectively support resilient design from concept through detailed engineering, tailored to Bunbury’s specific seismotectonic context.
