Perform Mechanical Rough-In Inspection using eAuditor
A Mechanical Rough-In Inspection is a detailed assessment conducted during the early stages of building construction to verify the installation of mechanical systems—such as HVAC (heating, ventilation, and air conditioning), ductwork, piping, and related equipment—before walls, ceilings, and floors are enclosed. This inspection ensures that all mechanical components are installed correctly, aligned according to design specifications, and compliant with applicable codes and standards.
Performing a Mechanical Rough-In Inspection using eAuditor ensures a comprehensive, structured evaluation of a building’s mechanical systems—including HVAC, piping, and related equipment—during early construction phases. The inspection verifies that all components are correctly installed, aligned, and compliant with design specifications and regulatory codes before walls, floors, and ceilings are enclosed. Using eAuditor provides digital documentation, real-time reporting, hazard logging, and corrective action tracking, enhancing safety, compliance, and operational efficiency.
