Oil and Gas Pipeline and Related Structures Construction

Establishments in this category are primarly engaged in the construction of oil and gas lines, mains, refineries, and storage tanks. 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 oil and gas pipeline and related structures construction. All structures (including buildings) that are integral parts of oil and gas networks (e.g., storage tanks, pumping stations, and refineries) are included in this industry.

Illustrative Examples:

Distribution line, gas and oil, construction
Oil refinery construction
Gas main construction
Petrochemical plant construction
Gathering line, gas and oil field, construction
Natural gas pipeline construction
Pumping station, gas and oil transmission, construction
Storage tank, natural gas or oil, tank farm or field, construction
Natural gas processing plant construction

Other Foundation, Structure, and Building Exterior Contractors

Establishments in this category are primarly engaged in building foundation and structure trades work (except poured concrete, structural steel, precast concrete, framing, masonry, glass and glazing, roofing, and siding). The work performed may include new work, additions, alterations, maintenance, and repairs.

Illustrative Examples:

Curtain wall, metal, installation
Forms for poured concrete, erecting and dismantling
Welding, on-site, contractors
Ornamental metal work installation
Fire escape installation
Decorative steel and wrought iron work installation

All Other Miscellaneous Electrical Equipment and Component Manufacturing

This includes establishments primarily engaged in manufacturing industrial and commercial electric apparatus and other equipment (except lighting equipment, household appliances, transformers, motors, generators, switchgear, relays, industrial controls, batteries, communication and energy wire and cable, wiring devices, and carbon and graphite products). Examples of products made by these establishments are power converters (i.e., AC to DC and DC to AC), power supplies, surge suppressors, and similar equipment for industrial-type and consumer-type equipment.

Illustrative Examples:

Appliance cords made from purchased insulated wire
Battery chargers, solid-state, manufacturing
Door opening and closing devices, electrical, manufacturing
Electric bells manufacturing
Extension cords made from purchased insulated wire
Inverters manufacturing
Surge suppressers manufacturing
Uninterruptible power supplies (UPS) manufacturing

Pipeline Transportation of Natural Gas

Establishments in this category are primarly engaged in the pipeline transportation of natural gas from processing plants to local distribution systems. This industry includes the storage of natural gas because the storage is usually done by the pipeline establishment and because a pipeline is inherently a network in which all the nodes are interdependent.

Engineering Services

Establishments in this category are primarly engaged in applying physical laws and principles of engineering in the design, development, and utilization of machines, materials, instruments, structures, processes, and systems. The assignments undertaken by these establishments may involve any of the following activities: provision of advice, preparation of feasibility studies, preparation of preliminary and final plans and designs, provision of technical services during the construction or installation phase, inspection and evaluation of engineering projects, and related services.

Illustrative Examples:
