FAQ

What work fits NAICS 237990?
  • Dredging, channel maintenance, and sediment relocation with heavy marine equipment, disposal planning, and turbidity control measures.
  • Construction of bulkheads, seawalls, revetments, and shoreline stabilization with concrete, armor stone, and marine piling and corrosion protection.
  • Levee, floodwall, and stormwater conveyance construction including large earthworks, embankment compaction, and installation of drainage control structures.
  • Major site preparation and heavy earthmoving for nonbuilding infrastructure such as dams, reservoir works, and large utility corridors requiring heavy-haul logistics.
When is NAICS 237990 a weak fit?
  • Vertical building construction: projects focused on multi-story occupied buildings where architectural envelope, interior finishes, and MEP fit-out drive scope rather than heavy civil earthworks or marine structures.
  • Pipeline and transmission line linear utility construction: long-distance buried pipeline or power transmission that emphasizes welding, leak testing, and right-of-way restoration but lacks heavy marine or large earth-retention components.
  • Design-only engineering services: deliverables limited to plans, specifications, or remediation studies without execution of heavy equipment earthwork, material placement, or construction performance obligations.
What solicitation language points to NAICS 237990?
  • Performance requirements listing heavy earthmoving metrics, allowable compaction values, embankment lift thickness, or staged dewatering and erosion control.
  • Deliverables require marine construction methods such as cofferdam installation, pile driving records, or dredging production reports and disposal plans.
  • Evaluation criteria emphasize past performance on large civil infrastructure projects, heavy equipment fleet availability, and integrated temporary works planning.
