Make the Underground Inspection after trenches or ditches are excavated, underground duct and fuel piping installed, and before any backfill be put in place.
The Rough-in inspection is to be made after the roof, framing, fire blocking and bracing are in place and all ducting, and other concealed components are complete, and prior to the installation of wall or ceiling membranes.
Schedule the final inspection after the building is complete, the mechanical system is in place and properly connected, and the structure is ready for occupancy.
