Job Overview

Collaborate closely with preconstruction, estimating, project management, and field teams

Support estimating efforts, including:

Quantity takeoffs

Scope development

ROM pricing

Design-build budgeting

Participate in value engineering (VE) and cost optimization discussions

Evaluate how design decisions affect labor, materials, schedule, and installation

Assist with coordination using AutoCAD and Revit (BIM experience is a plus)

Background as a Plumbing Engineer or Plumbing Designer

Strong understanding of plumbing system design, California codes, and constructability

Experience working in a design-build environment (required)
