Independent PlumbingQuality Control Inspections

Why GCs Use 3rd-Party Plumbing Inspections

• Reduce rework and tear-outs
• Avoid failed plumbing inspections
• Improve coordination with structural and electrical
• Identify routing conflicts early
• Ensure code compliance
• 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)

Our experience in forensic engineering, construction defect analysis, and expert mechanical evaluations gives us a clear understanding of how plumbing systems should be installed, how issues typically arise, and how they affect project performance. We apply this knowledge during inspections to help general contractors verify installation quality, improve coordination, and maintain compliance throughout the project.
