Mechanical Estimator: Multi-trade Modular - FabLogix

Kelso IndustriesDuncan, SC
Hybrid

About The Position

We are seeking an experienced and dynamic Mechanical Estimator responsible for preparing accurate, timely, and competitive cost estimates for industrial pipe fabrication projects, specifically, 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.

Requirements

  • Strong experience with model-based quantity take-offs using Navisworks.
  • Strong experience with orthographic and isometric piping take-offs.
  • Solid understanding of industrial pipe fabrication processes.
  • Solid understanding of modular construction principles.
  • Solid understanding of 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).
  • 5+ years of estimating experience in pipe fabrication, mechanical contracting, or industrial construction.
  • Experience estimating work for industrial clients such as pharma, chemical, data center, or manufacturing facilities.
  • 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.

Nice To Haves

  • Modular or prefabricated systems experience.

Responsibilities

  • Prepare detailed estimates for multi-trade modular assemblies (pipe, structural steel, supports, equipment integration) and structural steel associated with pipe racks, skids, and modules.
  • Perform quantity take-offs using model-based take-offs from Navisworks, orthographic drawings, and 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.
  • 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.
  • 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.
  • 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.

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.
