Horizontal Directional Drilling Contractors can also be classified as underground utility and excavation contractors.

An underground utility and excavation contractor is one whose services are limited to the construction, installation, and repair, on public or private property, whether accomplished through open excavations or through other means, including but not limited to, directional drilling, auger boring, jacking and boring, trenchless technologies, wet and dry taps, grouting, and slip lining, of main sanitary sewer collection systems, main water distribution systems, storm sewer collection systems, and the continuation of utility lines from the main systems to a point of termination up to and including the meter location for the individual occupancy, sewer collection systems at property line on residential or single occupancy commercial properties, or on multi occupancy properties at manhole or wye lateral extended to an invert elevation as engineered to accommodate future building sewers, water distribution systems, or storm sewer collection systems at storm sewer structures.

Underground utility and excavation contractors can install empty underground conduits in rights-of-way, easements, platted rights-of-way in new site development, and sleeves for parking lot crossings no smaller than 3/4 inches in diameter, provided that each conduit system installed is designed by a licensed professional engineer or an authorized employee of a municipality, county, or public utility and that the installation of any such conduit does not include installation of any conductor wiring or connection to an energized electrical system. An underground utility and excavation contractor shall not install any piping that is an integral part of a fire protection system beginning at the point where the piping is used exclusively for such system.

Maine Boring Contractors and its affiliates are fully licensed Directional Boring Companies as well as an Underground Utility and Excavation Contractors.

Maine Boring Contractors NAICS | Standard Industrial Classification

Maine Boring Contractors NAICS | Standard Industrial Classification

The Standard Industrial Classification SIC is a system for classifying industries by a four-digit code. Established in the United States in 1937, it is used by government agencies to classify industry areas. The SIC system is also used by agencies in other countries, e.g., by the United Kingdom's Companies House.

The NAICS replaced the SIC in 1997. Federal statistical agencies use NAICS for the collection, tabulation, presentation, and analysis of economic statistics. There will be no further revisions of the SIC, which was last updated in 1987.
