Analyze RFPs, RFQs, and federal project specifications to develop accurate and

competitive estimates.

Create and maintain bid schedules, track milestones, and ensure timely submission of

estimates.

Coordinate with project managers, engineers, and subcontractors to clarify scopes,

resolve discrepancies, and confirm pricing.

Solicit, review, and evaluate multiple subcontractor proposals across all trades; support

subcontractor negotiations and buy-out post-award.

Assist in developing preliminary project schedules, staffing plans, and budgets for

awarded projects.

Maintain cost databases, historical pricing, and takeoff records to improve estimate

accuracy and efficiency.

Support proposal teams with estimate breakdowns, bid narratives, and supporting

documentation.

Ensure all estimates and bid submissions align with FAR, DFARS, and agency-specific

requirements.

Qualifications : Required :

Minimum 3 years' experience in construction estimating, preferably for federal projects.

work.

Knowledge of federal procurement processes, regulations, and contract types.
