In Hobart, geophysics addresses the complex subsurface conditions shaped by Jurassic dolerite, Permian mudstone, and Quaternary alluvium, directly informing compliance with AS 1726 and the NCC. Our category integrates non-invasive techniques to map bedrock depth, fault zones, and fill materials critical for foundation design on the city’s sloping terrain. Common applications begin with a GPR survey to locate utilities and voids, then extend to MASW / VS30 profiling for seismic site classification under AS 1170.4.
These investigations support mid-rise commercial developments in the CBD, hillside residential subdivisions, and infrastructure upgrades where drilling access is limited. For vibration-sensitive structures or heritage assessments near Salamanca Place, we combine HVSR microtremor surveys with seismic tomography to constrain dynamic soil properties and map excavation depths across dolerite floaters. Each method delivers calibrated, repeatable data for geotechnical modelling without excessive intrusive works.
