BIM Designer, Mechanical

What you'll do

As a BIM Designer, Mechanical, you’ll develop and coordinate mechanical systems models (ductwork, hydronic piping, and equipment layouts) across our AI data center and industrial construction portfolio. You'll translate engineering markups and design criteria into fully coordinated, constructible Revit models, applying real mechanical engineering judgment rather than just drafting what you're told. This role sits inside our growing BIM function, working shoulder-to-shoulder with electrical, structural, and civil designers to keep one federated model as the single source of truth from design through fabrication and field support.

Responsibilities

• Develop mechanical system models in Revit from engineering markups, sketches, and design criteria, including ductwork, hydronic piping, and mechanical equipment layouts
• Size ductwork and piping based on airflow, velocity, pressure drop, and equipment requirements, applying sound engineering judgment when every detail isn't fully specified
• Produce mechanical plans, sections, details, and schedules directly from coordinated BIM models
• Proactively coordinate mechanical systems with structural, architectural, electrical, plumbing, and controls disciplines
• Run and participate in Navisworks clash detection, investigating root causes and driving resolutions rather than just flagging conflicts
• Track coordination issues through closure and ensure resolved changes are incorporated into the model
• Maintain model accuracy, organization, and compliance with Giga's BIM standards
• Support construction and field teams by resolving mechanical routing and coordination questions, incorporating field conditions into the model
• Perform quality-control reviews of mechanical models and drawings to catch errors and coordination gaps before release
