Site investigation in Perth must address the complex geology of the Swan Coastal Plain, including the deep sands, Tamala Limestone, and Guildford Clay formations that define local ground conditions. Comprehensive fieldwork, sampling, and in-situ testing are essential to comply with AS 1726 for geotechnical site investigations, ensuring structural designs account for reactive soils and variable water tables. Our approach integrates precise stratigraphic profiling with advanced methods like the CPT (Cone Penetration Test) to deliver reliable data on bearing capacity and settlement potential.
These investigations are critical for residential subdivisions, multi-storey developments, and infrastructure projects where foundation performance hinges on accurate subsurface models. We support engineers and builders by coupling direct push techniques with laboratory analysis to refine design parameters. For a complete ground assessment, our reporting also incorporates soil testing to quantify chemical aggressivity and compaction, ensuring every recommendation meets the specific demands of Perth's basins.
