• Define estimate bases, assumptions, exclusions, and estimating methodologies appropriate to scope, maturity, and project complexity.
• Translate technical, operational, and business requirements into structured estimates that support planning, prioritization, and execution decision-making.
• Evaluate estimate quality and recommend adjustments based on scope changes, market inputs, historical performance, and execution risks.
• Support development of estimate packages and documentation that can be consistently applied across projects and initiatives.
• Project Controls, Cost Analysis & Forecasting
• Analyze labor, materials, equipment, contractor, and indirect cost inputs to develop accurate and supportable cost projections.
• Monitor estimate-to-actual performance and identify trends, variances, and opportunities to improve forecasting accuracy.
• Maintain cost benchmarks, historical databases, unit rates, and estimating reference information to strengthen future estimating efforts.
• Support scenario analysis, what-if modeling, and alternative evaluations to inform project and business decisions.
• Collaborate with project controls and finance partners to align estimates with budgets, forecasts, and reporting requirements.
• Business Process & Service Quality Improvement
• Identify opportunities to improve estimating processes, templates, workflows, and data quality to increase consistency, efficiency, and usability.

• Partner with Operations, Engineering, Project Management, Supply Chain, Finance, and other stakeholders to gather scope information and validate estimate inputs.
• Facilitate alignment on assumptions, risks, schedule drivers, and resource needs to ensure estimates reflect business and operational realities.
• Communicate estimate development approach, key drivers, risks, and recommended actions to stakeholders and leadership.
• Serve as a knowledgeable resource for estimating methodologies, cost modeling, and estimate quality practices.
• Support cross-functional planning and prioritization by providing clear, timely, and decision-ready estimating information.
• Risk, Governance & Documentation
• Identify estimate risks, uncertainties, and key cost drivers and incorporate them into estimating assumptions and documentation.
• Maintain clear records of estimate methodologies, revisions, approvals, and supporting data to improve auditability and traceability.
• Ensure estimating outputs align with internal controls, project governance expectations, and applicable company standards.
• Support reviews of estimate quality, process compliance, and documentation completeness.
• Contribute to building scalable estimating practices that reduce rework and support consistent decision-making.
• Analytics, Reporting & Decision Support
• Prepare estimate summaries, dashboards, and reporting materials that support business planning and project reviews.
• Analyze estimating data to identify patterns, lessons learned, and opportunities to improve quality and predictability.
• Provide insights that help stakeholders evaluate project alternatives, prioritize investments, and manage execution risk.
