• 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
