Follow actual workshop photographs from sheet-metal fabrication and ventilation-component assembly to unit checks and packing preparation.
Sheet-metal fabrication
Workshop photographs show sheet-metal processing and component fabrication for equipment structures.
Ventilation assembly
An assembly photograph of an attenuating air diffuser shows the enclosure and internal components.
Unit checks
Open panels reveal heat-exchange components, pipework and an electrical cabinet. The original archive labels this unit as undergoing commissioning.
Ductwork and packing
Spiral ducts arranged in timber frames document finished components and their packing condition.

Bring traceable documents into the discussion.
Identify the model, drawing revision and inspection scope for each item.
Before manufacturing
Confirm operating conditions, selection sheets, dimensions, maintenance access and electrical interfaces.
During inspection
Agree inspection items, reporting formats and witnessing arrangements against the technical agreement. Photos do not replace test records.
Before delivery
Check equipment identification, drawings, manuals, and the certificates and spare-parts list agreed in the contract.
