• Establish the Basis of Estimate, including methodology, assumptions, exclusions, accuracy ranges, escalation, contingency, and risk allowances.

• Develop estimates using engineering quantities, equipment lists, material take-offs, productivity factors, historical cost data, and contractor or supplier quotations.

• Establish Cost Breakdown Structures aligned with project Work Breakdown Structures, schedules, procurement packages, and reporting requirements.

• Lead estimate assurance and quality reviews before stage-gate, funding, and investment approvals.

• Review estimate completeness, quantities, pricing, productivity assumptions, indirect costs, escalation, contingency, and risk provisions.

• Develop and maintain estimating databases, historical costs, unit rates, productivity factors, cost benchmarks, and escalation assumptions.

• Lead the preparation and review of project budgets, cost forecasts, cash-flow projections, and Estimate-at-Completion forecasts.

• Monitor commitments, expenditure, cost trends, variances, and potential budget overruns.

• Evaluate the cost impact of scope changes, engineering modifications, schedule movements, and project variations.

• Work closely with engineering teams to validate project scope, quantities, equipment lists, and material take-offs.

• Review engineering drawings, technical specifications, procurement packages, and construction work packages.

• Support value-engineering and cost-optimization activities.

• Prepare pre-tender estimates and support bid analysis, technical-commercial evaluations, and procurement recommendations.

• Review contractor and supplier quotations, cost submissions, variations, change requests, and commercial assumptions.

• Provide estimating inputs for feasibility studies, business cases, economic evaluations, and capital approval submissions.

• Present project estimates, cost movements, key cost drivers, risks, and recommendations to project management and senior leadership.

• Provide technical leadership, coaching, and quality assurance to the Senior Costing Engineer and other personnel supporting the estimating function.

• Drive continuous improvement in estimating methodologies, systems, databases, reporting, and cost-management processes.

• Ensure compliance with company governance, project controls standards, statutory obligations, safety requirements, and quality-management systems.

• Bachelor’s Degree in Engineering, Quantity Surveying, Construction Management, Cost Engineering, Finance, Economics, or a related discipline.

• Approximately 12–18 years of relevant experience in estimating, cost engineering, quantity surveying, project controls, or major capital-project delivery.

• At least 5 years of experience in a Senior, Principal, Lead, or supervisory estimating position.

• Proven experience preparing and reviewing CAPEX and OPEX estimates from conceptual and feasibility stages through detailed design and execution.

• Experience in mining, mineral processing, chemical processing, manufacturing, heavy industry, infrastructure, energy, or EPC/EPCM projects.

• Strong knowledge of estimating methodologies, Basis of Estimate, Cost Breakdown Structures, Work Breakdown Structures, budgeting, forecasting, cost benchmarking, contingency, escalation, and cost-risk analysis.

• Ability to interpret engineering drawings, technical specifications, equipment lists, material take-offs, construction work packages, and project schedules.

• Experience reviewing contractor quotations, tenders, cost submissions, variations, and change requests.

• Strong commercial acumen with the ability to identify cost risks, challenge assumptions, and recommend cost-optimization opportunities.

• Advanced Microsoft Excel skills, including cost modelling, forecasting, scenario analysis, and estimate database management.

• Familiarity with systems such as Primavera P6, SAP, Power BI, EcoSys, CostX, Oracle, Aconex, or equivalent enterprise project systems.

• Strong leadership, stakeholder-management, communication, and presentation skills.

• Ability to manage multiple project estimates and present or defend recommendations to senior stakeholders and governance committees.
