Construction Phase Support

At TERRATECH, we provide specialised geotechnical support throughout the construction phase, ensuring that ground conditions are properly assessed, monitored, and managed to meet both safety and specification requirements.

Our services are grounded in practical experience and technical rigour, supporting everything from bulk earthworks to foundation verification, working platform design, and real-time site monitoring. Whether you're working with variable ground conditions, managing groundwater impacts, or constructing critical infrastructure, our team delivers the insight needed to keep projects moving efficiently and compliantly.

Our Construction Support Capabilities Include:

  • Bulk Earthworks Supervision: Level 1 and Level 2 supervision in accordance with AS3798-2007

  • Subgrade Assessment: Evaluation and improvement strategies to meet project-specific performance requirements

  • Material Compliance & Sourcing: Assessment of site-won and imported materials for compaction and suitability

  • Temporary Works Advice: Retaining systems, working platforms, groundwater management, and stabilisation solutions

  • Foundation Verification: Onsite confirmation of founding conditions and pile integrity testing

  • Slope Risk Assessment & Mitigation: Analysis and monitoring for cut/fill stability during staged construction

  • Instrumentation & Monitoring:

    • Groundwater levels

    • Slope movement

    • Vibration

    • Earth resistivity (for electrical earthing or geophysical considerations)

  • Piling & Earthworks Supervision: Ensuring specification compliance and ground risk management during critical construction phases

  • Working Platform Design & Certification: Safe and compliant designs for pile rigs, cranes, and other heavy plant
