Job Summary
The Senior Fabrication Estimator is an experienced technical estimator responsible for complex fabrication pursuits across the company’s fabrication capabilities. The role develops complete fabrication estimates, leads technical reviews, advises leadership and Operations, and mentors estimators without requiring formal personnel-management responsibility. Estimates address material procurement, shop labor, equipment, subcontract services, quality requirements, and delivery. Structural steel and piping fabrication experience is preferred. Technical complexity, risk, specialization, and review structure govern assignment.

Essential Job Responsibilities

• Lead fabrication estimates from pursuit planning through proposal and turnover, defining shop fabrication, delivery, and any field scope boundaries. Estimating will not be limited to fabrication only if necessary.
• Review drawings, specifications, models, bills of material, and applicable fabrication details to establish quantities, fabrication requirements, scope gaps, and execution assumptions.
• Lead estimate reviews and provide independent QA/QC for fabrication pursuits, reconciling quantities, material costs, labor hours, exclusions, and pricing.
• Develop conceptual and detailed estimates for fabricated products and assemblies within the company’s capabilities, including materials, labor, equipment, subcontract services, and delivery.
• Estimate cutting, forming, machining, fitting, welding, assembly, handling, and loading, as applicable to the scope, using documented shop production rates and fabrication requirements.
• Obtain and evaluate quotes for raw materials, purchased components, detailing, coatings, specialty fabrication services, inspection, testing, freight, and other services required by the specifications.
• Advise Operations and leadership on fabrication sequence, shop capacity, procurement lead times, material waste, risk, contingency, value engineering, and commercial position.
• Mentor estimators and improve technical consistency without requiring formal personnel-management responsibility.
• Develop and maintain fabrication labor factors, material pricing, shop productivity benchmarks, weld quantities, historical cost data, and estimating tools and templates.
• Lead estimate turnover and lessons learned for assigned pursuits, communicating the basis of estimate, production assumptions, procurement requirements, inclusions, exclusions, and delivery commitments.

Minimum Qualifications

Required:

• Minimum of 8 years of relevant estimating or equivalent directly applicable construction or shop fabrication experience.
• Fabrication estimating experience, including material takeoff, shop labor development, supplier pricing, and fabrication methods.
• Demonstrated success leading complex or high-risk pursuits with minimal oversight.
• Advanced capability in fabrication cost development, estimate strategy, risk evaluation, QA/QC, and coordination with shop Operations, detailing, procurement, and project teams.
• Ability to mentor others and influence consistent estimating practices.
• Proficiency with estimating, digital takeoff, spreadsheet, reporting, and document-management systems; ability to interpret fabrication drawings, models, and specifications.
• Ability to travel periodically to offices, client locations, and project sites.
• Valid driver’s license and insurability when driving is required.
• Working knowledge of applicable fabrication codes and standards, welding requirements, material specifications, inspection and testing requirements, and their effects on cost and schedule.

Preferred:

• Structural steel and piping fabrication estimating experience preferred, including structural drawings, connection details, piping isometrics, and pipe spool fabrication. Experience with conceptual fabrication pricing, model-based quantity takeoff, and shop production planning is also preferred.
• Technical training, shop or field experience, or professional certification.
• Proficiency with HCSS HeavyBid and/or Tekla software preferred.

Potential Hazards:

• Potential exposure to extreme cold and hot temperatures
• Exposure to manufacturing, pipeline, and refining environment
• Exposure to noise above 85 decibels and intense odors
• Exposure to areas with limited visibility
