23799

Analysis

NAICS 23799 is the 2022 NAICS industry for other heavy and civil engineering construction, part of 2379 (Other Heavy and Civil Engineering Construction).

It has only one more detailed code, 237990, which covers exactly the same activities; the definition, index entries and statistics are on that page.

County Business Patterns counts 4,806 US establishments in this code in 2023, employing 84,360 people at an average annual payroll of $95,317 per employee (81st percentile of national industries). 52% of the establishments have fewer than five employees, which is close to the national mix.

Between 2018 and 2023 the number of establishments grew 12% and employment rose 22%. The 2018 count used NAICS 2017, so part of a large move can come from codes being redefined rather than from businesses opening or closing.
