The material list specifies sheet metal work including duct banks, installation hardware, fasteners, and various structural components with quantities and specifications. General notes address structural conditions, existing construction compatibility, referenced drawings, materials testing requirements, equipment location and modifications, and contractor responsibilities for final verification. Removal notes require that surveyed dimensions and destructive testing be conducted, with final disposal of the contractor's responsibility. The document includes specific installation notes indicating that all HVAC equipment and ducting must conform to ship structural standards, with particular attention to maintaining watertight integrity and meeting operational performance standards. Test notes require all equipment to operate within design parameters with control limits established by the vessel operator.
