  • Geological defect mapping and monitoring in accordance with the project specifications

Value Added to Project

JDK Geotech was commissioned to conduct geotechnical site investigations and supervise piling rig operations to ensure compliance with bedrock conditions. Our team adeptly applied a systematic approach to gather geotechnical and geological data, aligning with the requirements of the Australian Standard AS1726. Operating autonomously, we seamlessly integrated efficient site safety management and rigorous documentation protocols into our workflow.
