From Feasibility to Operation: How Consulting Engineers Add Value Across the Mining Lifecycle
Engineering expertise that strengthens mining projects from concept to closure
Mining is one of the most complex and capital-intensive industries in Australia. Every stage of a mine’s development—whether a greenfield project or a brownfields expansion—requires thousands of interlinked decisions that influence cost, safety, environmental impact, and operational performance.
While mining companies typically focus on strategy, geology, production, and commercial outcomes, it is the consulting engineers who provide the technical foundation that ensures these decisions are achievable, safe, and financially sound. From the earliest feasibility studies through to final decommissioning, engineering consultants play an essential role in risk reduction, compliance, design optimisation, and asset performance.
Trang Imagineering supports mining operations across Australia by delivering structural, mechanical, piping (SMP), and finite element analysis (FEA) services that add measurable value throughout the entire mine lifecycle.
Engineering Across the Mining Lifecycle
The modern mining lifecycle can be divided into four major stages:
Feasibility studies
Design and construction
Operation, maintenance, and optimisation
Closure and decommissioning
At each stage, consulting engineers provide specialist knowledge that reduces risk, improves accuracy, and ensures decisions are grounded in sound, defensible engineering practice.
Let’s break down each lifecycle stage and the engineering value it creates.
1. Feasibility Studies: Turning Concepts Into Buildable, Costed Projects
Feasibility studies—whether Scoping, PFS (Pre-Feasibility Study), or DFS (Definitive Feasibility Study)—set the technical and financial direction for the entire mining project. Mistakes at this stage are costly and often irreversible.
Consulting engineers contribute by providing:
Realistic SMP Costing and Engineering Scoping
Mine owners rely on consulting engineers to estimate:
Structural steel quantities
Concrete and foundation requirements
Mechanical equipment envelopes
Chutes, bins, and transfer points
Tanks, piping, pumps, and process equipment
Access structures, walkways, and platforms
Early SMP costing ensures capital budgets reflect real-world construction requirements—not theoretical estimates.
Fit-For-Purpose Preliminary Designs
Engineers develop early 3D models, layouts, load assumptions, and structural concepts that allow:
Flowsheet refinement
Space allocation
Material handling path evaluation
Equipment selection support
Risk assessment of key mechanical systems
Design Review and Practical Input
Consulting engineers identify:
Constructability challenges
Potential bottlenecks
Areas of excessive risk or cost
Equipment interactions
Code or compliance issues
This stage lays the groundwork for safe, efficient, and buildable project execution.
2. Design & Construction: From Engineering Drawings to Fabrication and Site Installation
Once a project advances past feasibility, detailed design becomes essential. This is where consulting engineers transform concepts into certified, buildable, compliant engineering packages.
Compliance With Australian Standards
Consulting engineers ensure structural and mechanical designs meet:
AS4100 (Steel structures)
AS3990 (Mechanical equipment)
AS/NZS 1170 (Structural loads, wind, seismic)
AS4041 / ASME B31.3 (Piping)
API-650 / API-653 (Storage tanks)
WHS and high-risk activity requirements
Without compliance, a project cannot be certified, approved, or safely built.
Fabrication-Ready SMP Drawings
Engineers prepare detailed drawings and models for:
Structural frames and towers
Conveyor gantries and supports
Pump bases and mechanical skids
Tanks, hoppers, and chutes
Access structures and platforms
Piping layouts and support systems
These drawings must be practical, clear, and aligned with fabricator capabilities to avoid delays and rework.
FEA for High-Risk or Complex Components
Finite Element Analysis supports the verification of:
Transfer towers
Crushers and vibrating equipment
Tanks under pressure or sloshing loads
High-temperature or abrasive environments
Equipment experiencing fatigue or cyclic loading
FEA helps ensure components will withstand real-world operating conditions.
Construction Support
Consulting engineers assist during construction by:
Reviewing shop drawings
Resolving site queries (RFIs)
Verifying as-built conditions
Providing clarification for installers
Conducting inspections and sign-off
This ensures the design intent is executed safely and correctly.
3. Operation & Maintenance: Retrofits, Life Extension, and Ongoing Verification
Once a mine is operational, engineering needs shift from construction to performance optimisation and risk management. Equipment ages, loads increase, and operating conditions change over time.
Consulting engineers play a critical role by providing:
Structural & Mechanical Retrofits
Working equipment rarely needs replacing if smart retrofits can extend its life. Engineers design:
Reinforcement plates
Additional bracing
New supports or stiffeners
Replacement chutes or liners
Upgraded piping systems
Retrofits are often significantly cheaper than full system replacements.
Fitness-For-Service Assessments
Engineers assess aged infrastructure using:
Non-destructive testing (NDT) inputs
Crack mapping
Measurement and alignment surveys
Material degradation assessments
FEA to evaluate remaining strength
This helps operators determine whether equipment is safe to keep running.
Ongoing Compliance Verification
Regular verification is essential for:
Tanks (API-653 requirements)
Piping systems
Access structures
Walkways and handrails
Conveyor galleries and gantries
Mobile fleet attachments
Consulting engineers provide the certification required for regulatory and insurance compliance.
Throughput Increases & Debottlenecking
When mines want to increase production, engineering input is needed to verify the structural and mechanical limits of existing assets.
Engineers evaluate:
Load paths
Conveyor tension
Structural deflection
Vibratory loads
Foundation integrity
This supports safe and efficient expansion.
Failure Investigation & Root Cause Analysis
When things go wrong, consulting engineers determine:
Why the failure occurred
Whether design assumptions were incorrect
Whether operational changes created new risks
How to prevent recurrence
This protects both personnel and production.
4. Closure & Decommissioning: Safe, Compliant, and Efficient End-of-Life Engineering
Every mine eventually reaches the end of its economic life. Closure is a highly regulated and scrutinised phase, requiring engineering input to ensure dismantling and rehabilitation are safe and compliant.
Consulting engineers support closure through:
Structural Assessment Before Demolition
Engineers evaluate whether structures can be safely dismantled or if temporary supports are required.
Mechanical and Piping Isolation Plans
Ensuring all energy sources—mechanical, electrical, hydraulic, thermal—are safely isolated before demolition.
Containment and Waste Handling Engineering
Many tanks, pipes, and chutes contain contaminated residues that require engineered handling plans.
Rehabilitation Support
Engineers may help design:
Drainage systems
Earthen structures
Stabilisation works
Foundation removal or burial plans
Closure done correctly protects the environment and reduces long-term liabilities.
How Consulting Engineers Add Measurable Value
Across all lifecycle stages, consulting engineers deliver benefits that cannot be achieved through mining operations alone.
1. Reduced Technical and Financial Risk
Engineering input ensures:
Realistic cost estimates
Safe design
Fewer surprises during construction
Lower probability of equipment failure
Reduced rework
Stronger regulatory compliance
2. Lower Whole-of-Life Costs
Good engineering minimises:
Over-design
Under-design
Maintenance burden
Shutdown frequency
Replacement costs
3. Independent, Third-Party Assurance
Independent engineers provide:
Verification for certification

Compliance documentation
Confidence for investors, insurers, and regulators
4. Improved Safety and Operational Performance

Safe operating conditions
Efficient layouts
Better maintainability
Optimised production throughput
