All Other Specialty Trade Contractors

NAICS 238990 · Specialty Trade Contractors · SBA size standard: $19 million average annual receipts

All other specialty trade contractors perform discrete construction tasks such as concrete cutting, core drilling, waterproofing, weatherization, scaffolding erection, demolition, and specialized installations. For a firm that bids on and performs concrete cutting, core drilling, and waterproofing across commercial and residential sites, the specialists turn bid requests into accurate estimates and proposals, proposals into scheduled work with permits, schedules into dispatch and crew assignments, work into material orders and safety checklists, and completed jobs into invoices with documentation. Trade-specific sequencing, site access rules, equipment mobilization and daily safety logs remain with the crew leads and owners.

  • Permits, inspections and utility locates that must be secured before any work begins
  • Equipment and tool mobilization: saws, core drills, scaffolding, pumps and containment systems that move between jobs
  • Daily safety and environmental compliance logs including dust control, water runoff and fall protection
  • Weather-dependent work with rain dates and temperature restrictions for coatings and sealants
  • Subcontractor coordination when the firm acts as prime or sub on larger projects
  • Change orders that arise from unforeseen site conditions such as rebar conflicts or hidden utilities
  • Repeat clients such as property managers and general contractors who expect standardized documentation and rapid response
