Department of Transportation obligations in Engineering Services (NAICS 541330)

DOT × 541330 is an engineering-services join, not a project census

The relationship is mechanical: awarding agency 069 and industry 541330 on the same award roll into $12,540,207,133.31. The join is awarding-agency 069 crossed with NAICS 541330, not a highway-project census and not DOT’s entire $415,288,372,621.56 book. Remove either filter and the number changes. This page never claims the pair caused the other side to exist. The extract does not list project names, mileposts, or engineer names.

2,433 award lines can look sparse or crowded. Either way, 2,433 is not equal 2,433 projects or 2,433 engineers. USAspending counts award records. Unique recipients remain off this packet. Highway construction (237310) and computer-systems design sit outside this total unless they also carry 541330. Neighboring codes stay outside $12,540,207,133.31.

2,433 awards behind $12.5 billion

About $5.15 million per award comes from dividing $12,540,207,133.31 by 2,433. Use that ratio as a scale check, not as a typical design contract and not a cost per mile. Count is not a count of projects, miles, or engineers. The agency parent remains $415,288,372,621.56; this slice is about 3.0% of that book.

Two thousand four hundred thirty-three lines are too many to narrate. Sort the DOT table by amount. Open Department of Transportation for the agency hub. This page will not invent a map of highway projects or a project census. Interstate-versus-transit folklore is not a mode split in this packet. Correlation with a published project count or a lane-mile inventory is not a packet finding.

Engineering obligations are not designs already stamped

NAICS 541330 is an engineering-services label on the award file, not a named infrastructure law. Quote $12,540,207,133.31 as obligations, not a punch-list of designs already stamped. A DOT capital program table with a year stamp is not this file. No fiscal year is attached here.

This extract does not split highway from transit from aviation engineering. DOT’s highway-construction join (237310) on this slice is a different NAICS and is not folded into 541330. Those splits are not in the facts.

What the DOT 541330 table omits

Omitted: project names, mileposts, or engineer names. Cited: $12,540,207,133.31, 2,433 awards, agency 069, NAICS 541330, parent $415,288,372,621.56. Mileposts and mode splits are not packet facts.

NAICS 541330 holds NAICS 541330 nationwide. All agencies lists agencies. All spending ties lists ties. Campaign contributions do not pay these obligations. Keep the pair intact when you quote $12,540,207,133.31.

Where the DOT × NAICS 541330 hubs live

Department of Transportation, NAICS 541330, All agencies, and All spending ties are the four related tables. 2,433 awards totaling $12,540,207,133.31 remain an engineering-coded administrative file, not a project census. Project names and lane-miles are not in this packet. USAspending.gov is the source. Do not annualize $12,540,207,133.31.

How to read the DOT × 541330 pair

Cite agency 069 (Department of Transportation), NAICS 541330 (Engineering Services), $12,540,207,133.31, and 2,433 awards together. Keep the obligation word. The join is the intersection, not a story about why the agency buys this industry. Leave this page for named lines. Project names and lane-miles are not in this packet. Readers who reuse this agency-industry snapshot should keep both keys in the same sentence, cite USAspending.gov, and treat award rows as records rather than unique vendors. This narrative does not invent a fiscal year, a recipient list, or an outlay total the packet omitted. Keep the obligation word on the headline dollar figure in every footnote. A later ingest can restate the headline dollars without changing the join itself. Do not add parent hubs into this cell. Unique recipients remain unpublished. Mean dollars per award stay a ratio of two packet facts, not a typical invoice.

Questions

How much DOT spending is coded to engineering services?

USAspending.gov shows $12,540,207,133.31 in obligations for Department of Transportation (agency 069) coded to NAICS 541330, across 2,433 awards. The sum is a commitment total, not outlays and not the agency’s full $415,288,372,621.56 book. Other industries are outside this join unless they also carry 541330.

Do 2,433 awards mean 2,433 highway projects?

No. Award count is a row count of 2,433 actions and can include continuations. It is not a count of projects, miles, or engineers. The packet does not name recipients. See Department of Transportation for named lines as USAspending stored them.

Is this the same as DOT highway construction (237310)?

No. Highway, street, and bridge construction is NAICS 237310, a separate DOT join on this slice. This page is 541330 only. Mixing design and construction invents a combined infrastructure figure. Original filings remain on USAspending.gov. Keep both sides of the join in the citation.

Are these engineering dollars already paid?

Not on this metric. Obligations are recorded commitments on awards. Outlays are payments from the Treasury. The $12,540,207,133.31 headline is the obligation rollup in SpendingVault’s extract. Remaining balances are not published in this packet. Original filings remain on USAspending.gov.
