Job Title: Mechanical Estimator –Multi-trade Modular

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, 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.

Key Responsibilities

Estimating & Preconstruction

• 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

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
