• Perform detailed quantity take-offs, labor and material pricing, and develop complete, accurate cost estimates for self-perform and subcontracted work.
• Solicit and evaluate subcontractor and supplier quotations, ensuring coverage, compliance, and alignment with project scope.
• Prepare and assemble complete bid packages, including scope sheets, clarifications, and exclusions, for internal review and submission.
• Coordinate and lead internal estimate review meetings to present bid strategies, assumptions, and final pricing recommendations.
• Identify and communicate value engineering opportunities, constructability concerns, and schedule impacts.
• Support post-bid activities, including subcontractor buyouts, scope alignment, and budget development.
• Maintain historical cost data and unit pricing databases to support future bids and continuous improvement.
• Build and maintain strong working relationships with subcontractors, vendors, engineers, and internal project teams.
