Senior Cost Estimator - Mining & Industrial

AECOM's Mining Team Canada is growing and is seeking a Senior Cost Estimator for its Mining and Industrial projects team. The successful candidate will be responsible for estimating all elements of project cost across the mining project lifecycle, including labor, materials, permanent equipment, consumables, construction equipment, logistics, contingency, escalation, and risk. This newly created position develops cost estimates for mining assets and related infrastructure such as brownfield/greenfield mine developments, processing facilities, materials handling systems, utilities, water management, site civil works, rail/port interfaces (where applicable), and supporting infrastructure. This position may be based in any of AECOM's Canadian offices. Sponsorship for Canadian employment authorization is not available for this position. All newly hired employees are required to attend an in-person Day 1 onboarding at an AECOM office location as a condition of employment.

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 (e.g., factored/parametric, unit-rate, first-principles); Specializes in one or more estimating disciplines for mining projects, including civil/earthworks, structural, mechanical, electrical/instrumentation, piping, process equipment, bulk materials handling, and infrastructure/temporary works; Prepares or assists in preparing order-of-magnitude, preliminary, definitive, and change estimates; 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; Works with Project Managers and discipline leads to evaluate CAPEX/OPEX budgets and support cost-driven decision-making; Utilizes company and industry historical data for estimates and benchmarking; Establishes and maintains cost databases and mining-specific parametric/factored estimating tools; Leads estimate reconciliation workshops and supports stage-gate estimate reviews; Identifies, evaluates, and quantifies project risks and opportunities, including cost and schedule impacts; Prepares bid packages, conceptual estimates, and analysis of subcontractor bids for mining and industrial scopes; Maintains consistent communications with estimators and stakeholders across mining pursuits and delivery teams; Prepares and/or coordinates full project estimates, supporting internal approvals and client

Requirements

Bachelor's degree in engineering, or a related field + 8 years of related cost estimating experience (mining/industrial preferred) or demonstrated equivalency of experience and/or 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 (e.g., early phase vs. definitive estimates) 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

Nice to have

Certification with AACE (e.g., CEP), RICS, ASPE or related construction/estimating credentials; Ability to read and interpret engineering drawings, specifications, RFPs and contracts for mining and industrial projects; Knowledge of InEight Cost Estimate / Hard Dollar; Knowledge of On-Screen Takeoff or ConstructConnect; Ability to support development of project schedules and estimate alignment with execution plans; Knowledge of MS Project and Primavera; Experience in both open pit and underground mining sectors; Fluent capability in spoken and written French and English
