Federal obligations in other heavy and civil engineering construction (NAICS 237990)
Federal contract awards coded NAICS 237990, other heavy and civil engineering construction, carry $48,372,546,825.38 in obligations in the USAspending.gov records indexed here. Only 3,987 awards sit under that total. These are obligations, not outlays. The code is heavy civil work that is not buildings (236220) and not highways, streets, and bridges (237310): dams, marine construction, and similar projects that contracting officers place in this remainder construction line.
Key figures
- Other heavy and civil engineering construction (NAICS 237990) shows $48,372,546,825.38 in obligations.
- Only 3,987 contract awards carry that total.
- 237990 is residual heavy civil work, not buildings (236220) or highways (237310).
- Figures are USAspending contract obligations, not outlays or grants.
What “other” heavy and civil construction includes
NAICS 237990 is the residual heavy-and-civil construction code: projects that are not residential, not commercial buildings, and not highway-street-bridge work. On USAspending.gov it tags contract awards classified that way—dams, levees, docks, and other heavy civil jobs that fit the remainder line. It is not a catalog of every Corps of Engineers project, because some of those jobs are coded to more specific construction NAICS.
Commercial and institutional buildings are 236220. Highways, streets, and bridges are 237310. Facilities support (561210) operates a site after it exists. Remediation (562910) cleans contamination rather than building a dam. The $48.4 billion figure is only awards tagged 237990.
Large dollars on 3,987 awards
The pairing of $48,372,546,825.38 with 3,987 awards is a heavy-construction pattern: fewer records than building construction, with large individual actions. USAspending records those commitments as obligations. This packet has no fiscal-year split and no outlay total. A dam or marine project can show a large obligation while construction and progress payments continue for years.
Outlays are the payments. Quote $48.4 billion as USAspending contract obligations coded to NAICS 237990, not as an infrastructure bill and not as cash already spent.
How to keep construction codes from blending
A federal campus can generate building construction, highway access work, and a marine or flood-control job under three different NAICS lines. Adding 237990 to 236220 and 237310 without a tagging rule will overstate “federal construction.” This page reports only the 3,987 awards and $48.4 billion tagged other heavy and civil engineering construction.
Remainder construction codes collect the jobs that are not buildings and not roads. NAICS 237990 did that to the tune of $48,372,546,825.38 in USAspending obligations on 3,987 awards. Dams, marine work, and similar heavy civil projects land here when tagged this way. A courthouse stays on 236220. A highway stays on 237310. A cleanup stays on 562910 if tagged as remediation. The 3,987 records are few relative to paving call-order codes, which fits large civil works. They are not a project census. Assistance for water infrastructure often has no NAICS. Cite USAspending contract obligations, not an infrastructure statute. Cite 3,987 awards. Use the industry table for the list.
What 237990 excludes
Assistance awards—formula highway or water grants—often lack NAICS and are outside this total. Engineering services (541330) is design, not construction. Ship building (336611) is manufacturing a vessel, not building a dock under the heavy-civil remainder code.

Using the heavy-civil industry page
Open the OTHER HEAVY AND CIVIL ENGINEERING CONSTRUCTION industry page for the award list under the headline. Compare 237990 with 236220 and 237310 on All industries. Cite obligations, not outlays, and keep the 3,987 award count so the concentrated heavy-civil pattern is visible.
Citing residual heavy civil work
Cite $48,372,546,825.38 in USAspending obligations on 3,987 awards tagged NAICS 237990, other heavy and civil engineering construction. The word other is the instruction: not buildings, not highways. Dams, marine work, and similar remainder jobs land here when tagged this way.
The 3,987 award count is a concentrated construction pattern. It is not a project census. Assistance water and levee grants often have no NAICS. Outlays are progress payments, not this field. Do not add 236220 or 237310 to this total; those facts are not in this packet.
Other heavy civil construction is the remainder of the heavy-and-civil group: not buildings, not highways. Dams, marine construction, and similar jobs land in the $48,372,546,825.38 total when tagged 237990. The 3,987 awards are relatively few, which fits large civil works more than paving call orders. A lock-and-dam vehicle and a harbor job can share the code; this packet does not split them.
Corps of Engineers work is not automatically 237990. Some of it is buildings, some is highways, some is remediation, some is this remainder. The tag decides. Cite USAspending obligations on 3,987 awards coded 237990. Do not call the figure an infrastructure law. Do not add grant-funded water projects that have no NAICS.
Questions
- How much is obligated on NAICS 237990 heavy civil construction?
- USAspending.gov contract awards coded NAICS 237990 show $48,372,546,825.38 in obligations across 3,987 awards. That total is obligations, not outlays, for other heavy and civil engineering construction. USAspending.gov records the amount as contract obligations, not outlays, on awards tagged NAICS 237990.
- Does this include highway and bridge construction?
- No. Highways, streets, and bridges are NAICS 237310. This table’s $48,372,546,825.38 is the residual other heavy and civil line, not 237310. The packet total is $48,372,546,825.38 across 3,987 awards; assistance awards often have no NAICS and stay outside the industry rollup.
- Are federal buildings in 237990?
- Commercial and institutional building construction is NAICS 236220. 237990 is other heavy civil work. Building dollars tagged 236220 are not inside this total. Treat the 3,987 figure as an award-record count, including orders and modifications, not as a physical inventory of products or sites.
- Do 3,987 awards mean 3,987 dams or docks?
- No. The 3,987 figure counts contract award records, including modifications. It is not a project inventory. One job can generate many awards. This guide does not add a fiscal-year split.
