Federal obligations in engineering services (NAICS 541330)

What engineering services covers in USAspending

NAICS 541330 classifies establishments that apply physical laws and engineering principles to design, development, and related services. On federal contract awards the code is used when that professional work is the industry assigned to the award. It can appear on systems engineering, civil design, test support, and similar contracted effort. It does not automatically include construction of the thing being designed, and it does not include every scientist on a federal payroll.

Research-and-development NAICS lines are separate. So are computer systems design, management consulting, and all-other professional services. A program office can buy engineering under 541330 while buying hardware, software, or R&D under other codes. The $321.5 billion total is only the slice tagged engineering services. Readers who treat it as all technical work the government buys will over-count this code and under-count the others.

Obligations of $321.5 billion, not outlays

USAspending.gov records obligations on contract awards. Engineering services contracts often run as task-order vehicles with many modifications. Each of those actions can add to $321,496,224,160.04. This packet has no fiscal-year split, so the headline is the industry aggregate, not an annual engineering budget. Agencies can de-obligate unused balances; the warehouse figure is the net recorded amount on tagged awards, not a ceiling that will all be spent.

Outlays are invoice payments. Professional-services work is typically billed as it is performed, so obligation and payment can be closer in time than on a ship or aircraft buy—but they are still different fields. Quote $321.5 billion as USAspending contract obligations coded to NAICS 541330.

Why 58,215 awards matter next to the dollars

Engineering services shows 58,215 awards, a high record count relative to some hardware industries with similar or larger dollar totals. That pattern fits a services code: many task orders, delivery orders, and modifications rather than a few production lots. The count is still not a headcount of engineers. One large vehicle can generate hundreds of award rows. Use the industry table to see concentration versus spread among recipients.

Limits of the engineering-services rollup

Assistance awards—grants and cooperative agreements that fund engineering at universities or labs—often have no NAICS and therefore do not sit in $321,496,224,160.04. In-house federal engineering is not a contract award and is also absent. Construction, R&D, and IT codes that sit beside 541330 in the NAICS manual are neighboring tables, not subsets of this one.

SpendingVault aggregates USAspending.gov contract data. Both the dollar total and the 58,215 award count can change after corrections. This guide restates the packet facts; the live industry page is the working table.

Reading the engineering services industry page

Go to the ENGINEERING SERVICES industry page for the award list under the $321.5 billion headline. Place 541330 among other professional and technical codes on All industries. Keep obligations distinct from outlays, and keep the 58,215 award count in any citation so the services-volume pattern is not lost.

Citing engineering services as a professional-services cut

A usable citation is: USAspending.gov shows $321,496,224,160.04 in obligations on 58,215 contract awards coded NAICS 541330. Add that the figure is obligations, not outlays, and that it is engineering services rather than R&D or construction. That extra clause prevents the most common mix-up on technical federal work.

The 58,215 award count is part of the citation, not optional color. Without it, a reader may imagine a handful of huge design contracts. With it, the services-volume pattern is visible. If you need to know which agencies bought the work, leave this guide and use the industry page table. This file restates packet facts only.

Engineering services sit in the professional, scientific, and technical group of NAICS, not in manufacturing and not in construction. That placement matters when a program office buys a design under 541330 and later buys the thing designed under a production code. The $321,496,224,160.04 total does not follow the hardware into production. It stays with awards that kept the engineering tag. Modifications that add test support, drawing packages, or systems-engineering labor can all enlarge the same industry sum if they stay coded 541330.

Because 58,215 is a large award count, some readers describe engineering services as fragmented. Fragmentation is a hypothesis, not a fact in this packet. A few indefinite-delivery vehicles can generate thousands of task orders. Concentration is visible only in the industry table recipient mix. This guide will not invent that mix. It will repeat that USAspending obligations, not outlays, are the field behind $321.5 billion.

Questions

How much federal money is obligated under NAICS 541330 engineering services?

USAspending.gov contract awards coded NAICS 541330 show $321,496,224,160.04 in obligations across 58,215 awards. That is an obligation total, not outlays, and it covers contract awards with this industry code only. USAspending.gov records the amount as contract obligations, not outlays, on awards tagged NAICS 541330.

Does engineering services include federal R&D contracts?

Not automatically. Research and development uses other NAICS codes. The $321,496,224,160.04 total is for awards tagged engineering services (541330). R&D dollars coded elsewhere do not roll into this industry table. The packet total is $321,496,224,160.04 across 58,215 awards; assistance awards often have no NAICS and stay outside the industry rollup.

Why does engineering services have 58,215 awards?

The 58,215 figure counts contract award records, including task orders and modifications coded to 541330. Professional-services vehicles often produce many rows. It is not a count of engineers employed or of distinct design projects. Treat the 58,215 figure as an award-record count, including orders and modifications, not as a physical inventory of products or sites.

Are university engineering grants in this total?

Usually not. NAICS on USAspending comes from contract awards. Assistance awards may not carry NAICS, so they are outside the $321,496,224,160.04 industry total. Look at assistance data for grant-funded engineering. This guide does not add a fiscal-year split. Quote the live industry page if you need the current award list under ENGINEERING SERVICES.
