Federal obligations in oil and gas pipeline and related structures construction (NAICS 237120)

Pipeline construction, not power-line NAICS 237130

NAICS 237120 covers oil and gas pipeline and related structures construction. Gathering lines, pump stations as related structures, and similar civil work can land here when the award is tagged 237120. Power and communication line construction (237130) is a sibling heavy-civil class. The $3,183,132,552.81 total is the oil-and-gas pipeline construction tag, not “all energy infrastructure.”

A transmission-line vehicle tagged 237130 will not raise this pipeline row. A pipeline-construction vehicle tagged 237120 will. SpendingVault reports the USAspending award tag, not a PHMSA mileage census and not an FEC employer string such as “energy.”

644 awards on a $3.18 billion obligation stock

Six hundred forty-four awards produced $3,183,132,552.81 in obligations. That is a thin action count. Large pipeline vehicles can dominate; the packet does not name them. The table shows tagged dollars and the 644-award count, not miles of pipe.

Obligations move with new awards, options, and modifications, including deobligations. Outlays are payments and are not this $3,183,132,552.81 rollup. A multi-year vehicle can show a large commitment while invoices follow performance. The industry page does not convert obligations into a cash calendar.

How USAspending attaches this NAICS

USAspending.gov stores NAICS on contract actions. energy-infrastructure grants and many tribal-energy assistance awards often have no NAICS field. Those dollars will not add to the 644 awards. Open program pages for grant-funded activity in this industry.

The label is a Census NAICS classification. It is not a PHMSA mileage census and not campaign-finance text. Cite USAspending.gov via SpendingVault for $3,183,132,552.81 and the 644-award count.

What the 237120 table is and is not

The hub lists recipients and awards that share this NAICS tag. A large obligation is a disclosed commitment. It is not a finding that a line leaked, that a right-of-way failed, or that a small business was excluded. SpendingVault does not score outcomes from the dollar total.

Use award IDs, not the $3,183,132,552.81 headline, to separate two companies. Subcontractors may be missing if the prime coded 237120. UEI and name changes are ordinary in the file.

Neighboring 2371 heavy-civil codes

Power and communication line construction (237130) is a separate page. Adding it to $3,183,132,552.81 would mix electric and fiber lines with oil-and-gas pipeline construction. That recode is not this page.

Assistance without NAICS remains outside the 644-award count. For a recipient that also holds grants, open the recipient record. This guide stays on contract NAICS 237120 from USAspending.gov. Keep obligations distinct from outlays.

Pipe in the ground versus wires and operations

A power-line award tagged 237130 will not raise the 644-award count. A pipeline-construction vehicle tagged 237120 sits in $3,183,132,552.81 even if the same prime also holds a 237130 line job. SpendingVault does not merge those rows. Pipeline *operations* sit on transportation NAICS, not this construction class.

Searchers who want “all federal energy construction” must add 237130 and other 237 lines and will still miss grants. This page does not perform that recode. Cite contract NAICS 237120 only. Do not treat the row as an FEC occupation called pipeline. The $3,183,132,552.81 figure remains an obligation stock on USAspending.gov. Modifications that cut a spread will lower the running total without publishing a mileage statistic on this hub. Open award rows for product descriptions. Neighboring 2371 lines stay on their own pages unless those awards were tagged 237120.

A pipeline spread tagged 237120 still sits in $3,183,132,552.81; a transmission job tagged 237130 does not. The 644 awards remain an action count, not a mile census. Keep pipeline-operations NAICS on their own pages. Cite USAspending.gov contract NAICS 237120 only. The headline is still obligations, not outlays. Energy grants without NAICS stay outside this contract rollup. Do not add 237130 into $3,183,132,552.81 without documenting a recode. The 644 awards stay an action file, not a mileage roster. Open award rows for CLIN-level descriptions the NAICS hub does not publish. Neighboring codes stay on their own SpendingVault industry pages unless those awards were tagged 237120. Keep obligations distinct from outlays on this rollup. Assistance awards without NAICS remain outside the contract tag. The packet reports only this NAICS tag from USAspending.gov contract actions, not outlays and not assistance without a NAICS field. Do not treat this industry total as an FEC employer string or as a cash-outlay extract from Treasury.

Questions

How much has the federal government obligated under NAICS 237120?

USAspending.gov contract aggregates on SpendingVault show $3,183,132,552.81 in obligations across 644 awards tagged oil and gas pipeline and related structures construction. The number is obligations, not outlays. Assistance awards without NAICS are omitted. It is not an FEC employer string and not a combined total of neighboring NAICS codes.

Does this include power and communication line construction?

Power and communication line construction is NAICS 237130. Those awards will not add to the $3,183,132,552.81 total unless tagged 237120. The 644 awards are the oil-and-gas pipeline construction contract tag from USAspending.gov via SpendingVault. Adding 237130 is a recode you must document on this page.

Does this include operating pipelines?

Pipeline transportation operations use other NAICS lines, not 237120 construction. Those awards will not add to the $3,183,132,552.81 total unless tagged 237120. The 644 awards are the construction contract tag. Open transportation-industry pages for operations, not this construction rollup from USAspending.gov.

Are these figures outlays or obligations?

They are obligations: legally binding commitments on contract actions. Outlays are payments and are not this $3,183,132,552.81 rollup. Modifications can change obligations without a same-day payment. SpendingVault cites USAspending.gov contract NAICS for the 644 awards, not a Treasury cash extract.
