• Lead and manage mechanical estimating efforts for facility projects across all bid phases.
• Oversee the development of accurate, complete mechanical estimates derived from drawings, specifications, and bid documents.
• Assign estimating responsibilities and manage workload distribution across the estimating team.
• Review and approve detailed takeoffs for piping, welding, equipment, valves, structural components, and mechanical systems.
• Ensure labor build-ups are developed using appropriate production rates, crew compositions, historical data, and execution strategies.
• Provide technical oversight to validate constructability, installation methods, and labor assumptions.
• Direct coordination with Supply Chain to solicit, evaluate, and normalize vendor and subcontractor pricing.
• Establish and enforce estimating standards, methodologies, and documentation requirements.
• Lead identification and documentation of risks, assumptions, exclusions, and clarifications.
• Support bid strategy development, value engineering, and alternative construction approaches.
• Participate in pre-bid meetings, job walks, and internal estimate reviews.
• Ensure estimate summaries, cost breakdowns, and pricing packages are accurate and executive ready.
• Support conceptual, budgetary, FEL, and detailed estimates as required.
• Ensure complete estimate logic, quantities, assumptions, and risks are communicated during project handoff.
• Provide Project Controls with validated cost data for job setup, WBS alignment, and cost tracking.
• Manage multiple bids simultaneously and provide status updates to leadership.
• Maintain organized, auditable estimate files and supporting documentation.
• Perform takeoffs and data entry task as required to support workload.
• Leadership & Management Responsibilities: Mentor, coach, and develop senior, junior, and entry-level mechanical estimators.
• Establish performance expectations, accountability, and continuous improvement within the estimating team.
• Participate in hiring, onboarding, training, and performance evaluations of estimating personnel.
• Serve as the primary technical authority for mechanical estimating questions and issue resolution.
• Promote consistency, accuracy, and professionalism across all mechanical estimates.
• Lead post-bid and post-job reviews to capture lessons learned and improve estimating accuracy.

Required Technical Skills

• Advanced proficiency in mechanical estimating for piping, welding, equipment installation, and structural components.
• Strong understanding of piping materials, pressure classes, fittings, fabrication, and erection practices.
• Expert-level ability to develop and review detailed labor estimates using crew-based production rates.
• Advanced interpretation of P&IDs, isometrics, mechanical drawings, and scope documents.
• Experience overseeing unit-rate, resource-based, and detailed line-item estimates.
• Proficiency in estimating software (InEight, Navisworks, Bluebeam, or similar).
• Advanced Excel capability (complex formulas, lookups, pivots, cost models).
• Strong knowledge of mechanical construction means and methods, including rigging, hydro-testing, and commissioning.
• Familiarity with ASME, API, and applicable mechanical construction standards.
• Ability to identify constructability risks, productivity impacts, and schedule influences.
• Understanding of indirect costs, equipment rates, consumables, labor burdens, and allowances.
• Experience developing conceptual and budgetary estimates with limited information.
• Knowledge of WBS structures, cost codes, and estimating alignment with project controls.
• Ability to support schedule logic, durations, and manpower planning.
