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:
- Development applications with geotechnical conditions
- Complying development requiring site or footing information
- Requests concerning excavation, slopes, retaining walls or neighbouring assets
- Design teams needing coordinated geotechnical input
Geotechnical information matched to an actual DA or CDC request
Development application and complying development requirements depend on the proposal, site conditions, planning controls and the request from the relevant approval authority or certifier. A geotechnical report is not automatically required for every Sydney or NSW development.
A request may concern residential site classification, excavation depth, neighbouring assets, retaining walls, slope stability, fill, groundwater or another project-specific issue. Reviewing the exact wording helps avoid ordering a report that does not answer the relevant question.
Important project and ground considerations
- The actual council, certifier or approval-authority request
- Proposed excavation, retaining, slope or foundation conditions
- Architectural drawings, survey and relevant structural or civil design
- Clear limitations, responsibilities and any additional investigation triggers
What the assessment can include
- Review of the exact council, certifier or designer request
- Identification of the geotechnical questions that must be answered
- Site investigation and analysis proportionate to the proposal
- Coordination with supplied survey, architectural and structural information
What you receive
- Report structured around the relevant approval questions
- Clear recommendations and responsibilities for the project team
- Transparent assumptions, limitations and further-work triggers
- Responses to reasonable technical clarification within the agreed scope
What to provide for your quotation
The clearest quote starts with enough information to understand your actual project, site constraints and required deliverables.
- Exact written council, certifier or request-for-information wording
- Current architectural plans, survey and proposed development details
- Any existing geotechnical, structural, drainage or site assessment reports
- Target submission timing and safe site-access information
