Senior Cost Estimator, Mining & Industrial Projects

AECOM (New); Northeastern Ontario; On-site; CAD 105,000 - 155,000; Full time

Job summary

AECOM’s Mining Team Canada is seeking a Senior Cost Estimator to develop cost estimates for mining projects across the lifecycle, including labor, materials, equipment, and logistics, with emphasis on basis of estimate, assumptions, and risk.

The successful candidate will support CAPEX/OPEX budgeting, perform benchmarking, maintain cost databases, and lead reconciliation workshops while coordinating with PMs and discipline leads.

Qualifications

• Bachelor’s degree in engineering, or a related field, + 8 years cost estimating experience (mining/industrial preferred) or demonstrated equivalency of experience/education.
• Extensive knowledge of cost estimating, construction methodologies, engineering design principles, and applicable industry standards, procedures, and best practices.
• Experience with class estimate frameworks commonly used in industrial/mining and documenting assumptions/contingency/risk.
• Strong understanding of construction means, methods, and sequencing for industrial/mining sites (including brownfield execution constraints and shutdown/turnaround interfaces where applicable).
• Demonstrated ability to plan, organize, lead, execute, review, and effectively present complex cost estimating assignments and projects.

Responsibilities

• Develops estimates aligned to mining industry deliverables, including Basis of Estimate (BoE), estimating plan, assumptions/exclusions, indirect strategy, and contingency methodology.
• Provides estimates for each project phase: conceptual / scoping, pre-feasibility, feasibility, detailed design, and construction / execution.
• Prepares detailed cost estimates using industry-accepted methods and tools appropriate to the maturity of engineering deliverables.
• Ability to specialize in one or more estimating disciplines commonly required for mining projects, including civil/earthworks, structural, mechanical (fixed plant), electrical/instrumentation, piping, process equipment, bulk materials handling, and infrastructure/temporary works.
• Prepares or assists in the preparation of order-of-magnitude, preliminary, definitive, and change estimates using appropriate methods and techniques.
• Prepares material, equipment, and labor take-offs from mining and industrial design deliverables.
• Develops and applies indirect and construction execution assumptions relevant to mining environments.
• Performs cost comparison analyses between AECOM estimates, contractor/EPC/EPCM estimates, and vendor budget pricing; supports reconciliation and benchmarking.
• Works with Project Managers and discipline leads to evaluate the appropriateness of CAPEX/OPEX budgets and to support cost-driven decision-making and value opportunities.
• Utilizes appropriate company and industry historical data to support estimates and benchmarking, including equipment pricing, productivity norms, installation factors, and location indices.
• Establishes and maintains cost databases and mining-specific parametric/factored estimating tools.
• Leads estimate reconciliation workshops with the project team and supports stage-gate estimate reviews.
• Identify, evaluate, and quantify project risks and opportunities, including their potential cost and schedule impacts, and support the development of formal cost and schedule risk assessments as required.
• Prepares bid packages, conceptual estimates, and analysis of subcontractor bids for mining and industrial scopes, including bulk earthworks, concrete, structural/mechanical erection, electrical/I&C, piping, and SMP packages.
• Maintains consistent communications with other estimators and stakeholders across mining pursuits and delivery teams.
• Prepares and/or coordinates preparation of full project estimates, supporting internal approvals and client.
