When this service is useful
The right scope depends on your development, site access, ground conditions and the information needed by your project team. This service is commonly used for:
- Buildings where shallow foundations may not be suitable
- Bored-pier, pile or deep-foundation concepts
- Variable fill, soft soil, shallow or weathered rock
- Projects requiring founding-depth and geotechnical design inputs
Investigation matched to the foundation concept
Deep-foundation investigation depth and methods depend on loads, likely foundation type, ground variability and the depth of influence.
The report provides geotechnical information for the foundation designer and identifies construction-stage verification where appropriate.
Important project and ground considerations
- Loads and foundation concept
- Depth and continuity of competent founding strata
- Fill, soft layers, rock weathering and groundwater
- Installation, inspection and verification requirements
What the assessment can include
- Review of proposed loads, foundation concept and site constraints
- Boreholes, sampling and testing proportionate to required depth
- Engineering description of soil, rock, fill and groundwater
- Foundation parameters and construction considerations within scope
- Inspection or additional investigation requirements
What you receive
- Interpreted subsurface profile
- Project-specific foundation and founding-level advice
- Relevant geotechnical parameters with assumptions and limitations
- Construction verification and further-work triggers
What to provide for your quotation
The clearest quote starts with enough information to understand your actual project, site constraints and required deliverables.
- Structural loads and foundation concept
- Architectural plans and survey
- Access and drilling constraints
- Previous reports and designer questions
Piling & Foundation Geotechnical Services across Sydney and NSW
Piling and foundation investigations can be scoped across Sydney and the Illawarra with appropriate field resources coordinated where needed. Ground conditions and approval requirements must always be considered site by site.
