Understand the ground. Define the decision.

Tailings design, analysis & drawings

Develop and review tailings engineering packages around a documented design basis. From concept options to staged raises and closure, the work links site characterisation, operating assumptions, analysis and construction requirements.

Possible scope outputs

• Design-basis and data-gap register
• Scoped analysis, sensitivity checks and calculation records
• Drawings, specifications and technical review comments

Field investigation & ground models

Plan geotechnical investigations around the uncertainty that affects the engineering decision. The scope can include CPT/CPTu, drilling, core recovery, test pits, block sampling, groundwater observations and targeted laboratory testing.

Possible scope outputs

• Investigation scope, location plan and sampling schedule
• Field records and sample traceability requirements
• Factual data compilation and interpreted ground model

Mining earthworks & risk investigation

Discuss earthworks design, construction interfaces and the investigation of geotechnical concerns. Separate observations, assumptions and conclusions so actions can be traced back to their basis.

Possible scope outputs

• Earthworks scope, design inputs and construction interfaces
• A record of identified issues and supporting evidence
• Prioritised actions, further investigation and review requirements

GISTM, ANCOLD & WA assurance

Scope evidence-based gap assessments and audit support against the requirements that apply to the facility. Keep GISTM conformance, ANCOLD guidance and Western Australian regulatory obligations distinct in the assessment basis.

Possible scope outputs

• Assessment scope and criteria register
• Evidence matrix and documented findings
• Prioritised gap and action register

EoR & independent review engagements

Discuss Engineer of Record (EoR) support and Independent Tailings Review Board (ITRB) engagement requirements. Define the mandate, technical responsibilities, independence and reporting arrangements before appointing a formal role.

Possible scope outputs

• Proposed terms of reference and responsibility matrix
• Document request and review schedule
• Technical comment and response register

FMEA, SQRA & QRA workshops

Bring technical and operational knowledge into a structured risk discussion. Scope Failure Modes and Effects Analysis (FMEA), semi-quantitative risk assessment (SQRA) or quantitative risk assessment (QRA) around a defined facility, decision and evidence base.

Possible scope outputs

• Workshop brief, agenda and pre-reading list
• Failure-mode or scenario register
• Assumptions, uncertainties and control observations

Dam safety reviews & performance

Scope a Dam Safety Review (DSR) around the facility's condition, design basis, operating history and current knowledge. Connect document review and site observations to explicit findings and a manageable programme of actions.

Possible scope outputs

• Review plan and document register
• Site observation and technical assessment records
• DSR report within the agreed professional scope

Laboratory programmes & interpretation

Connect sampling and testing to the parameters needed for design and review. Programmes can cover classification, density, permeability, consolidation, compaction and appropriate shear-strength testing, including triaxial testing.

Possible scope outputs

• Sampling and laboratory test schedule
• Laboratory RFQ and reporting requirements
• Data-quality review and parameter interpretation

Surveillance, monitoring & closure

Develop a clear link between observed performance, expected behaviour and operational decisions. Discuss monitoring reviews, surveillance documentation, trigger-action frameworks and closure-related geotechnical studies.

Possible scope outputs

• Monitoring and surveillance review scope
• Data-gap, trend and action registers
• Scoped closure studies or technical reviews
