Mechanical Estimator –Multi-trade Modular

Duncan, SC or open to Hybrid remote

Full-time

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.

• Prepare detailed estimates for:
• 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

• 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

• 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).

• 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

• 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

• 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

• 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.
