Complete quantity take-offs from drawings, specifications, models, schedules, and field information.
Develop crew compositions, production rates, work-hour and shift assumptions, and execution durations with operations and project teams.
Prepare estimate summaries, cost breakdown structures, and pricing schedules that meet client and internal requirements.
Bid and Proposal Support   Review requests for proposal, invitations to tender, statements of work, technical specifications, commercial terms, and addenda to identify pricing requirements and gaps.
Participate in bid kick-off meetings, site visits, constructability reviews, and estimate strategy sessions.
Maintain clear records of assumptions, clarifications, exclusions, and qualifications for each estimate.
Support bid forms, pricing narratives, executive summaries, commercial reviews, bidder questions, post-bid clarifications, and negotiations.
Pricing, Procurement, and Market Intelligence   Partner with Supply Chain to develop bidder lists, procurement strategies, bid packages, and award recommendations.

Participate in peer and management reviews and approval gates in accordance with bid governance requirements.
Maintain an auditable estimate file containing source documents, calculations, quotations, approvals, and revision history.
Lead or support estimate handover to the project delivery team and explain estimate structure, assumptions, subcontractor coverage, allowances, and identified risks.

Support change estimates, cost forecasting, and commercial analysis during project execution, as required.
