NAICS 237990

What is the NAICS code 237990?

The NAICS code 237990 is applied to those industries related to Other Heavy and Civil Engineering Construction.

This industry comprises establishments primarily engaged in heavy and civil engineering construction projects (excluding highway, street, bridge, and distribution line construction). The work performed may include new work, reconstruction, rehabilitation, and repairs. Specialty trade contractors are included in this industry if they are engaged in activities primarily related to heavy and civil engineering construction projects (excluding highway, street, bridge, distribution line, oil and gas structure, and utilities building and structure construction). Construction projects involving water resources (e.g., dredging and land drainage), development of marine facilities, and projects involving open space improvement (e.g., parks and trails) are included in this industry.

Illustrative examples:

• Channel construction
• Land drainage contractors
• Dam construction
• Marine construction
• Dock construction
• Microtunneling contractors
• Dredging (e.g., canal, channel, ditch, waterway)
• Nuclear waste disposal site construction
• Earth retention system construction
• Flood control project construction
• Park ground and recreational open space improvement construction
• Railroad construction
• Golf course construction
• Subway construction
• Horizontal drilling (e.g., cable, pipeline, sewer installation)
• Trenching, underwater
• Hydroelectric generating station construction
• Tunnel construction

Therefore, all companies engaged in any industrial activity related to this type of business are grouped under category 237990 in the North American Industry Classification System.

This industrial activity of NAICS code is structured as follows:

• 23 - Construction
• 237 - Heavy and Civil Engineering Construction
• 2379 - Other Heavy and Civil Engineering Construction
• 23799 - Other Heavy and Civil Engineering Construction
• 237990 - Other Heavy and Civil Engineering Construction
