Engineering Services
NAICS Code: 541330
Reading the Engineering Services Contract Record
USAspending.gov records show $53.9B in cumulative federal contract awards classified under NAICS code 541330 — Engineering Services. The NAICS code is chosen by the contracting officer at the time of solicitation and reflects the principal purpose of the procurement, not the full business activity of the awardee. That distinction matters because a single contractor can receive awards under a dozen NAICS codes depending on which product or service line each contract targets, and size-standard thresholds (expressed in either annual revenue or employee count) vary by code to determine small-business eligibility.
Industry totals at the NAICS six-digit national industry level are tighter signals of true market concentration than broader two- or three-digit rollups, because they isolate firms competing for substantively similar scopes of work. The $53.9B aggregate here spans every fiscal year present in the underlying dataset and includes all award vehicles — definitive contracts, task orders on IDIQs, BPA calls, and purchase orders — so comparing this total against a single-year federal procurement data system report will typically overstate recent activity.
For vendors evaluating market entry, the practical layer under $53.9B is the competitive landscape attached to NAICS 541330: which contracting offices issue the solicitations, which size standard applies (crucial for 8(a), HUBZone, WOSB, and SDVOSB set-aside eligibility), and which existing primes hold incumbent positions. SAM.gov registration requires selecting this code when it applies to your offering, and federal market-research templates rely on historical spend by NAICS to scope small-business goals. The totals on this page establish the size of the opportunity; the individual award records expose how the money is distributed among firms.

About This Industry
Engineering Services (NAICS 541330) has received $53.9B in total federal contract awards. The North American Industry Classification System (NAICS) is the standard used by federal agencies to classify business establishments by industry when awarding contracts.
Federal agencies use NAICS codes to categorize the goods and services they procure. Businesses must select the appropriate NAICS code when registering in the System for Award Management (SAM.gov) and when bidding on federal contracts.
How NAICS Classification Works in Federal Procurement
The NAICS taxonomy is jointly maintained by the U.S. Census Bureau, the U.S. Bureau of Economic Analysis, and Statistics Canada and the Mexican Instituto Nacional de Estadística y Geografía. It is updated on a five-year revision cycle (current vintage 2022, with the 2027 revision in public comment) to reflect emerging industries, mergers of obsolete categories, and reorganization within sectors. For federal contracting, the contracting officer assigns a single NAICS code to each solicitation based on the principal purpose of the procurement — the activity that represents the largest share of the contract value. That single-code assignment governs which size standard applies, which small-business set-aside programs are eligible, and how the contract rolls up into industry-level federal procurement statistics.
Because the assigned NAICS code is tied to the solicitation rather than to the awardee's primary business activity, a single contractor frequently appears in award records under multiple NAICS codes. A large defense integrator, for example, may hold contracts classified under professional services codes alongside manufacturing codes depending on what the government bought. Analyzing concentration within Engineering Services requires interpreting the $53.9B aggregate as the value of work classified here — not as the total revenue of the firms that received the awards.
Size Standards and Small-Business Eligibility
Every NAICS code has an associated size standard published by the U.S. Small Business Administration (SBA). Size standards are expressed either as average annual receipts (typically over the three most recently completed fiscal years) or as average employee count, depending on the industry. The size standard determines whether a firm qualifies as a small business for SBA programs including 8(a) Business Development, HUBZone, Women-Owned Small Business (WOSB), Service-Disabled Veteran-Owned Small Business (SDVOSB), and standard small-business set-asides. SBA updates size standards on a recurring review schedule and through statutory adjustments; firms must self-certify against the standard in effect at the time of the contract opportunity.
For procurement professionals examining Engineering Services (NAICS 541330) historically, the practical question is how the $53.9B in cumulative awards distributes between small-business set-asides and full-and-open competition. The award-level detail in USAspending.gov includes the small-business flag, the set-aside type (if any), the awardee's reported socioeconomic status at the time of award, and the place-of-performance state and county. Those fields combined let analysts measure small-business participation rates, identify dominant prime contractors, and surface counties where federal spending in this industry concentrates.
Why Industry-Level Totals Matter
Industry-level federal procurement totals at the NAICS six-digit national industry level are widely used by market-research firms, trade associations, congressional committees, and inspector-general offices to track concentration, identify trend lines, and assess whether federal demand is supporting the broader civilian economy in this sector. The $53.9B aggregate published here covers every fiscal year present in the underlying USAspending.gov dataset and includes definitive contracts, task and delivery orders against IDIQ vehicles, BPA calls, purchase orders, and modifications. Because USAspending.gov posts data with a lag and corrections to historical records are routinely applied, the figure on this page is point-in-time accurate to the dataset version noted in our methodology and may differ from the live federal procurement data system (FPDS) at the moment you read this.
