FAQ

What work fits NAICS 237120?
  • New buried transmission pipeline construction including right-of-way clearing, trenching, stringing, welding, coating, and backfill compaction.
  • Installation of cathodic protection systems and grounding for newly installed pipeline segments, with testing and certification documentation.
  • Execution of hydrostatic pressure testing and inspection with temporary test facilities, test records, and non-destructive examination reporting.
  • Site restoration and erosion-control implementation such as reseeding, mulching, installation of silt fences, and post-construction stabilization verification.
When is NAICS 237120 a weak fit?
  • Pipeline maintenance and repair services - missing large-scale new-construction activities such as right-of-way clearing, full-length pipe laying, and initial welding operations.
  • Prefabrication of pipeline modules in a manufacturing yard - missing on-site trenching, in-situ welding, field coating, and backfilled installation tasks.
  • Utility distribution line construction for non-hazardous water or sewer mains - missing design and safety treatments specific to hazardous liquid or hydrocarbon transport and related regulatory controls.
What solicitation language points to NAICS 237120?
  • Performance Work Statement lists right-of-way clearing, stringing, field welding, coating, backfill compaction criteria, and restoration deliverables.
  • Contract includes requirements for hydrostatic testing, non-destructive weld inspection reports, and cathodic protection installation certificates.
  • Bid evaluation weights past performance on new pipeline construction, safety plan compliance, and key personnel with field welding and pipeline supervision qualifications.
