Variant of NAICS 2002 - Durable and Non-Durable Goods Manufacturing Industries

237 - Heavy and Civil Engineering Construction

This subsector comprises establishments whose primary activity is the construction of entire engineering projects (e.g., highways and dams), and specialty trade contractors, whose primary activity is the production of a specific component for such projects. Establishments may produce new construction, or undertake additions, alterations, or maintenance and repairs to existing structures and works. Establishments in this subsector are classified based on the types of structures that they construct.

Specialty trade contractors in this subsector generally provide specialized services of a type related to heavy and civil engineering construction projects and not normally performed on buildings or building related projects. For example, specialized equipment is needed to paint lines on highways. This equipment is not normally used in building applications so the activity is classified in this subsector. Traffic signal installation, while specific to highways, uses much of the same skills and equipment that are needed for electrical work in building projects and is therefore classified in Subsector 238, Specialty Trade Contractors.

Construction projects involving water resources (e.g., dredging and land drainage) and projects involving open space improvement (e.g., parks and trails) are included in this subsector. Establishments whose primary activity is the subdivision of land into individual building lots usually perform various additional site-improvement activities (e.g., road building and utility line installation) and are included in this subsector.

• Exclusion(s):

  Establishments primarily engaged in:

  • construction activities normally performed on buildings or building related projects (See 238 Specialty Trade Contractors)

2371 - Utility System Construction

This industry group comprises establishments primarily engaged in the construction of distribution lines and related buildings and structures for utilities (i.e., water, sewer, petroleum, gas, power, and communication). All structures (including buildings) that are integral parts of utility systems (e.g., storage tanks, pumping stations, power plants, and refineries) are included in this industry group.

2372 - Land Subdivision

This industry group comprises establishments primarily engaged in servicing raw land and subdividing real property into lots, for subsequent sale to builders. Land subdivision precedes building activity. The building sites created by land subdivision may be residential lots, commercial tracts or industrial parks.

Servicing of raw land entails some physical improvements, such as land clearing or excavation work for the installation of roads and utility lines. While the extent of work varies from project to project, the establishments classified in this industry are primarily engaged in subdivision activity that includes physical improvement of the land. Establishments that perform only the legal subdivision of land are not included in this industry.

2373 - Highway, Street and Bridge Construction

This industry group comprises establishments primarily engaged in the construction of highways (including elevated), streets, roads, airport runways, public sidewalks, or bridges. The work performed may include new work, reconstruction, rehabilitation, and repairs. Specialized trade activities related to highway, street, and bridge construction (e.g., installing guardrails on highways) are included.

2379 - Other Heavy and Civil Engineering Construction

This industry group comprises establishments, not classified to any other industry, primarily engaged in constructing heavy and civil engineering works. The work performed may include new work, reconstruction, rehabilitation, and repairs. Specialized trade activities related to these engineering and civil construction projects (such as marine pile driving) are included. Construction projects involving water resources (e.g., dredging and land drainage), development of marine facilities, and open space recreational construction projects (e.g., parks and trails) are included in this industry.
