Other Heavy and Civil Engineering Construction

NAICS 237990 · Heavy and Civil Engineering Construction · SBA size standard: $45 million average annual receipts

Firms in this industry build heavy civil infrastructure projects that are not classified elsewhere such as outdoor sports facilities, athletic fields, running tracks, retaining walls, dams, levees, water control structures, marine construction and specialized site preparation. For a contractor that designs and builds municipal athletic fields, running tracks and retaining walls, the specialists turn client RFPs into bids, bids into awarded contracts, contracts into permitting and material orders, and schedules into daily crew and equipment assignments. Blueprints, geotechnical reports, safety plans and regulatory sign-offs stay with the project manager and field engineer.

What makes this business different

  • Complex bids that require takeoffs from plans, soil reports, labor and equipment rates, and bonding capacity
  • Multi-agency permitting that involves environmental reviews, stormwater plans, traffic control and utility locates
  • Heavy equipment and specialized assets such as compactors, graders, laser-guided finish rollers and erosion control materials that must be scheduled and maintained
  • Weather-dependent outdoor work with rain delays, freeze restrictions and seasonal bidding windows
  • Subcontractor coordination for electrical, irrigation, fencing and specialty surfacing trades
  • Daily safety tailboards, erosion control inspections, compaction testing and material delivery logs
  • Progress billing tied to pay applications, retainage and lien waivers from all tiers
  • Municipal clients who require prevailing wage, DBE participation tracking and final punch lists
