• Compile labor, material, equipment, subcontract, and indirect-cost inputs using approved sources and methods.
• Solicit and organize vendor and subcontractor quotations; document coverage, qualifications, and missing information.
• Identify scope gaps, design discrepancies, commercial concerns, and project risks for senior review.
• Maintain estimate files, assumptions, clarifications, exclusions, and supporting documentation.
• Meet assigned deadlines and participate in estimate reviews, site visits, pre-bid meetings, and turnover activities.
• Use approved estimating, takeoff, CRM, and document-management systems accurately.
• Apply review feedback and demonstrate measurable growth toward independent estimate execution.

Preferred:
