The Heavy and Civil Engineering Construction 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. Specialty trade contractors in Heavy and Civil Engineering Construction generally are performing activities that are specific to heavy and civil engineering construction projects and are not normally performed on buildings. (more...)
The work performed may include new work, additions, alterations, or maintenance and repairs.
Specialty trade activities are classified in this subsector if the skills and equipment present are specific to heavy or civil engineering construction 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.
Establishments in this subsector are classified based on the types of structures that they construct. This classification reflects variations in the requirements of the underlying production processes.

Location Quotient: The ratio of the local percentage of employment in a given industry to the national percentage of employment in the same industry.
An LQ greater than 1 indicates a higher-than-average concentration of employment in the given industry.
National Growth: The change in local employment that would have occurred for a specific industry had
it grown at the national growth rate of all industries combined.
Industry Mix: The additional gain (or loss) in local employment that would have occurred for a specific
industry (additional to the national growth effect) due to the industry growing faster (or slower) nationally
than the rate of all industries combined.
Regional Shift: The additional gain (or loss) in local employment for a specific industry beyond the national
growth and industry mix effects resulting from the industry growing faster (or slower) than the same
industry nationally.

Industry Staffing Patterns: Major Occupations
related to NAICS 237 - Heavy and Civil Engineering Construction in the Oregon-Washington WIRED Region
Occupational experience is largely self-reported.
Applicants counts include only those registered with the Oregon Employment Department.
They do not represent all job applicants across the WIRED region.
Applicants may be listed under multiple occupational categories, so summing applicant counts across occupational classifications will result in some double-counting.
