FAQ

What work fits NAICS 238990?
  • Installation of custom environmental enclosures, lab fume hoods, or cleanroom components requiring specialized mounting and sealing procedures.
  • Precision equipment rigging and anchoring for large scientific instruments including foundation modifications and vibration isolation work.
  • Selective interior demolition or specialty abatement tied to a unique trade scope outside general demolition contracts.
  • Retrofit of specialty building systems such as high-voltage grounding mats, radio frequency shielding, or testing chambers when classified outside standard electrical or mechanical trades.
When is NAICS 238990 a weak fit?
  • General building construction where the contractor manages multiple trade disciplines, overall site coordination, and subcontractor integration; this NAICS excludes full general contracting responsibility.
  • Electrical contracting jobs that involve full electrical system design, wiring, and code compliance projects; this NAICS excludes primary electrical system scope that falls under electrical-specific codes.
  • HVAC and plumbing installations requiring licensed mechanical contractors and integrated system commissioning; this NAICS excludes core mechanical system contracts governed by specific mechanical trade NAICS.
What solicitation language points to NAICS 238990?
  • Statement of work describes a narrow, standalone installation or modification with distinct trade deliverables and project-specific shop drawings rather than full design-build responsibilities.
  • Bid attachments require trade-specific qualifications, specialized tooling lists, or proof of experience performing the named niche installation as the prime.
  • Performance schedule is short-duration, single-discipline tasks with payment milestones tied to discrete installation milestones instead of broader construction phases.
