Field Mechanical Estimator

Responsibilities

• Lead comprehensive estimating efforts for assigned industrial and commercial mechanical projects, including piping, process mechanical systems, equipment setting, rigging, structural supports, fabrication, maintenance work, and facility upgrades.
• Own the complete scope mapping process, including quantity logic, production assumptions, quote coverage, temporary-works allowances, safety and permit assumptions, explicit exclusions, clarifications, and the written basis of estimate.
• Review and interpret drawings, specifications, addenda, P&IDs, piping plans, isometrics, spool drawings, equipment specifications, rigging information, structural details, shop and fabrication requirements, and contract documents to fully define project scope.
• Perform complete material, labor, equipment, and subcontractor takeoffs, determining manpower needs, crew mix, productivity assumptions, crane and lift requirements, tooling, trucking, staging, and overall pricing strategy.
• Conduct system analysis of mechanical systems and process piping, evaluating equipment setting, rigging requirements, access constraints, tie-ins, shutdown windows, sequencing, logistics, constructability, and field execution requirements.
• Complete site walks and field measurements to validate project scope, existing site conditions, access, utilities, safety constraints, and practical installation assumptions.
• Collaborate with engineers, clients, contractors, project managers, field leadership, and business-line leadership to clarify technical requirements, commercial intent, and execution plans.
• Develop accurate and competitive estimates using historical cost data, current market pricing, supplier input, subcontractor quotes, and field productivity feedback.
• Utilize digital takeoff tools, Bluebeam, Microsoft Excel, estimating databases, and project coordination or field reporting software to prepare detailed estimates and documentation.
• Support strong integration between estimating, operations, field leadership, shop and fabrication teams, procurement, safety, finance, and business-line leadership to ensure alignment between estimates and execution.
• Contribute to the growth of the estimating function by helping to refine standards, procedures, tools, cost history, and review practices.
• Apply sound commercial judgment and execution literacy to balance competitiveness, risk, margin, and field realities when developing estimates.
• Communicate clearly and professionally with internal and external stakeholders, presenting assumptions, clarifications, and basis of estimate in a structured, transparent manner.

Requirements

• Minimum 5 years of experience in mechanical field installations, industrial construction, mechanical estimating, or a closely related role.
• Strong understanding of mechanical systems, process piping, rigging, equipment setting, structural supports, fabrication processes, and shop-to-field coordination.
• Demonstrated experience performing quantity takeoffs, labor and equipment planning, site-condition reviews, and field productivity assessments.
• Experience with crane operations, hoisting plans, rigging requirements, heavy equipment coordination, and temporary works (preferred but strongly beneficial).
• Proficiency with Bluebeam, Microsoft Excel, estimating databases, and digital takeoff tools.
• Experience using field reporting, estimating, or project coordination software to support estimating and project planning.
• Strong mathematical and analytical skills with high attention to detail.
• Excellent organizational, communication, negotiation, and decision-making abilities.
• Proven commercial judgment and execution literacy, with the ability to balance competitiveness, risk, margin, and field realities.
• OSHA 30 certification.
• Valid driver’s license and willingness to travel to job sites as needed.

Essential Skills

• Mechanically inclined mindset with a strong interest in mechanical, piping, rigging, and industrial construction work.
• Experience in mechanical, construction, and MEP environments.
• Background in digital takeoff and quantity takeoffs for mechanical and piping scopes.
• Hands-on experience with field reporting and project coordination in an industrial or mechanical construction setting.
• Familiarity with fabrication-supported estimating work and shop-to-field coordination processes.
• Additional safety training beyond OSHA 30 is preferred.
• Ability to work collaboratively across estimating, operations, field leadership, shop and fabrication, procurement, safety, finance, and business-line teams.
• Strong commitment to accuracy, transparency, and disciplined commercial decision-making.
