FAQ

What work fits NAICS 333611?
  • Purchase of packaged gas or steam turbine-generator sets delivered as matched units with factory acceptance testing and rotor balancing certificates.
  • Contracts that require supplier responsibility for mechanical coupling, matched rotor-generator integration, and factory commissioning prior to shipment.
  • Supply of spare turbine rotors or matched rotor-generator subassemblies manufactured to original equipment tolerances for replacement in existing units.
  • Procurements for turbine-generator sets delivered with factory-supplied control panels and guaranteed performance curves for specified operating load points.
When is NAICS 333611 a weak fit?
  • Electric power equipment procurements focused on transformers or switchgear without an included turbine prime mover, because turbine manufacturing and matched unit delivery are absent.
  • Field erection and commissioning contracts that install turbine-generator units supplied by others, since no manufacturing or matched-unit production is required.
  • Maintenance, repair, or overhaul contracts that perform rotor refurbishment and parts replacement without manufacturing new matched turbine-generator assemblies.
What solicitation language points to NAICS 333611?
  • Scope lists factory acceptance testing, rotor balancing reports, and guaranteed vibration and thermal performance curves for the supplied unit.
  • Evaluation criteria require demonstrated manufacturer experience building complete turbine-generator sets and provision of factory acceptance test witness reports.
  • Labor categories include turbine design engineers, rotor shop technicians, factory testing personnel, and generator coupling specialists.
