Engineering Services (NAICS 541330) covers engineering consulting, design, and analysis work. While this code includes traditional civil and mechanical engineering, it also encompasses software engineering, systems engineering, and engineering analysis relevant to federal contracting. Many tech companies use 541330 as a secondary code for engineering-intensive projects.
What Businesses Fall Under This Code
541330 includes engineering consulting firms, engineering design companies, and engineering analysis firms. For tech companies, this applies to software engineering consulting, systems engineering, engineering analysis of technology systems, and technology infrastructure engineering. This code is broader than IT services and captures technology work with engineering focus.
SBA Size Standard and What It Means
The SBA size standard for 541330 is $8.5 million in annual revenue—significantly lower than IT services codes (541511-541519). This is because engineering services are classified differently than IT services in SBA regulations. If your revenue is under $8.5 million and you do engineering work, you qualify as small business under this code.
Federal Spending in This Category
Federal engineering services spending exceeds $40 billion annually across all disciplines. Technology-specific engineering (software engineering, systems engineering) represents a growing portion of this category.
Top Agencies Buying in This Code
The Department of Defense, NASA, Department of Energy, National Institutes of Health, and the Federal Aviation Administration are top spenders in engineering services. DoD particularly values engineering consulting for weapons systems, cyber engineering, and defense infrastructure.
Tips for Tech Companies Using This Code
Register for 541330 if your company provides engineering consulting or design services with a technology focus. This code is valuable for aerospace/defense contractors, companies providing systems engineering for federal projects, and technology consultancies with engineering focus. Show demonstrated expertise in federal engineering standards and processes.
Pro Tip: If your revenue is under $8.5 million and you do engineering work, registering under 541330 may be more advantageous than IT services codes due to lower size standard. However, you can use multiple codes—if you do both IT and engineering, register for both.
