FAQ

What work fits NAICS 238910?
  • Clear and grub sites, remove vegetation and non-structural improvements, and prepare building pads for subsequent vertical construction contracts.
  • Perform mass grading, cut-and-fill balancing, and establish rough grades to achieve design drainage patterns and final elevation targets.
  • Excavate and backfill for foundations, footings, and basements to design elevations, coordinate haul-off of unsuitable material, and provide temporary erosion controls.
  • Provide trenching, bedding, and backfill to support later utility installation contracts while marking and protecting existing underground utilities.
When is NAICS 238910 a weak fit?
  • General building construction that includes structural framing, finishes, and commissioning, because site preparation lacks responsibility for vertical construction and building trades.
  • Utility installation contracts that include laying pipe or conduit, system connection, testing, and commissioning, since site preparation stops before system installation and operational testing.
  • Environmental remediation projects that require hazardous waste characterization, regulated disposal, and remediation design, because site preparation excludes remediation oversight and handling of regulated wastes.
What solicitation language points to NAICS 238910?
  • Line items specify topsoil stripping areas and depths, erosion and sediment control measures, cut-and-fill quantities, and haul-off and disposal instructions.
  • Contract requires compaction testing criteria, elevation tolerances for rough and finish grades, utility locating and protection procedures, and sequencing to support follow-on trades.
  • Scope expressly excludes installation of permanent utilities and structures, defines demolition limits, and requires restoration of adjacent areas after clearing and grading.
