Job Title: Mechanical Estimator – Pipe Fabrication, Multi-trade Modular, Structural Steel

Location: Duncan, SC or open to Hybrid remote

Job Type: Full-time

Job Summary: We are seeking an experienced and dynamic Mechanical Estimator responsible for preparing accurate, timely, and competitive cost estimates for industrial pipe fabrication projects, including process piping, multi-trade modular assemblies, and associated structural steel. This role supports industrial clients across markets such as pharmaceutical, chemical, data centers, food & beverage, and advanced manufacturing.

The ideal candidate is highly skilled in model-based take-offs, understands fabrication-driven estimating, and can collaborate effectively with engineering, operations, and project teams to develop executable scopes and pricing.

Key Responsibilities:

Estimating & Preconstruction

  • Prepare detailed estimates for:
    • Carbon steel, stainless steel, and specialty process piping
    • Multi-trade modular assemblies (pipe, structural steel, supports, equipment integration)
    • Structural steel associated with pipe racks, skids, and modules
  • Perform quantity take-offs using:
    • Model-based take-offs from Navisworks
    • Orthographic drawings
    • Isometric drawings
  • Develop labor, material, equipment, and subcontractor pricing aligned with fabrication and modular execution strategies
  • Evaluate constructability, fabrication sequencing, and modularization opportunities during the estimating phase

Model & Drawing Review

  • Navigate federated models to identify scope, extract quantities and validate model data against drawings and specifications
  • Coordinate with engineering to resolve discrepancies between models, isometrics, and orthographic views

Cost Development & Risk Assessment

  • Apply current market material cost data and production rates specific to shop fabrication and modular assembly
  • Solicit and evaluate vendor and subcontractor quotes for pricing and availability
  • Ensure compliance with industry standards, codes, and safety regulations
  • Identify project risks, assumptions, exclusions, and clarifications
  • Develop pricing narratives and scope summaries to support proposal submissions
  • Participate in internal estimate reviews and handoffs to project management

Collaboration & Client Support

  • Support business development and client pursuits with conceptual, budgetary, and detailed estimates
  • Participate in scope alignment meetings with mechanical contractors, EPCs, and owners
  • Assist in post-award estimate validation and turnover to operations
  • Assist with procurement of material post-award

Qualifications & Skills:

Technical Skills

  • Strong experience with:
    • Model-based quantity take-offs using Navisworks
    • Orthographic and isometric piping take-offs
  • Solid understanding of:
    • Industrial pipe fabrication processes
    • Modular construction principles
    • Structural steel fabrication and erection interfaces
  • Familiarity with piping specifications, material grades, welding requirements, and QA/QC impacts on cost
  • Proficiency in estimating software, Excel, and digital take-off tools (e.g., AutoCAD, MS Excel, Navisworks).

Experience

  • 5+ years of estimating experience in:
    • Pipe fabrication, mechanical contracting, or industrial construction
    • Modular or prefabricated systems (preferred)
  • Experience estimating work for industrial clients such as pharma, chemical, data center, or manufacturing facilities

Professional Attributes

  • Detail-oriented with strong analytical and organizational skills
  • Ability to interpret incomplete or evolving design documents
  • Strong communication skills for cross-functional and client-facing collaboration
  • Practical, execution-focused mindset aligned with fabrication-driven delivery

Success Metrics

  • Accuracy of estimates versus actual fabrication and modular execution costs
  • Timeliness and completeness of estimate deliverables
  • Quality of scope definition, assumptions, and risk identification
  • Positive feedback from operations, engineering, and project teams during handoff

Benefits:

  • Competitive salary and performance-based incentives.
  • Health, dental, and vision insurance.
  • 401(k) with company match.
  • Professional development and career growth opportunities.
  • Paid time off and company holidays.
