Prepare and review estimate basis documents, assumptions, exclusions, risks, and estimate methodologies.
Coordinate with engineering, procurement, construction, project controls, and business development teams to develop accurate project cost forecasts.
Develop direct and indirect cost estimates including labor, materials, equipment, subcontractors, construction services, and home office costs.
Utilize historical data, benchmarking, and productivity metrics to validate estimate accuracy and identify opportunities for improvement.
Perform quantity reviews and estimate validation using engineering deliverables, vendor quotations, and historical project information.
Evaluate project risks and develop appropriate contingency recommendations based on estimate maturity and project complexity.
Lead estimate review meetings and present estimate results to project leadership, clients, and executive management.
Support proposal development, project pursuits, and business development activities.
Mentor junior estimators and provide technical guidance on estimating methodologies, systems, and best practices.
