Independent HVAC Oversightfor Construction Projects

Why GCs Use 3rd-Party HVAC Inspections

• Reduce mechanical rework
• Avoid failed mechanical inspections
• Improve coordination with plumbing, electrical, and structural
• Identify ductwork conflicts early
• Ensure equipment placement meets code and manufacturer requirements
• Protect schedule integrity
• Provide documentation for owners and inspectors

Our Background & Experience

EIS Forensic Engineering has provided mechanical engineering support on projects involving major national general contractors, including:

• Coastal Construction (via Walter P Moore)
• McCarthy Building Companies (pre-construction litigation analysis)
• Whiting-Turner (expert witness services via Griffith Davison)

Through our work supporting general contractors and legal teams on complex mechanical disputes, we've gained deep insight into the installation practices, coordination challenges, and field conditions that influence HVAC system performance. We use this experience to provide inspections that help project teams verify quality, identify risks early, and maintain schedule integrity.
