Engineering Services
Size Standard: $25.5 million
NAICS code 541330 covers Engineering Services, one of the largest categories in government contracting. This industry includes establishments primarily engaged in applying physical laws and principles of engineering in the design, development, and utilization of machines, materials, instruments, structures, processes, and systems.
The federal government is the world's largest purchaser of engineering services, from designing military systems to building infrastructure. Agencies like the Army Corps of Engineers, Naval Facilities Engineering Command, and NASA award billions in engineering contracts annually. State and local governments also have extensive engineering needs.
Contractors under NAICS 541330 provide services including civil engineering, mechanical engineering, electrical engineering, systems engineering, construction management, and engineering consulting. The breadth of this code covers virtually all engineering disciplines except specialized architectural or surveying work.
The varied size standards (ranging from $22.5 million to $47 million depending on military or civilian use) reflect the diversity of engineering work. Small businesses compete effectively, particularly through set-asides, 8(a) contracts, and subcontracting opportunities with large primes.

What services are covered under NAICS code 541330?
NAICS 541330 covers engineering services including civil, mechanical, electrical, structural, and systems engineering, as well as engineering consulting and construction management.
What is the size standard for NAICS 541330?
Size standards vary by exception - Military & Aerospace Engineering is $47 million, Marine Engineering is $47 million, and other engineering is $25.5 million in average annual receipts.
How competitive is NAICS 541330 for small businesses?
Very competitive but with substantial opportunities. Agencies have significant small business goals for engineering. Success requires past performance, qualified engineers, and often specialty certifications.
What certifications help win NAICS 541330 contracts?
Professional Engineer (PE) licensure is often required. Security clearances are needed for defense work. ISO 9001, CMMI for engineering, and agency-specific certifications add competitiveness.
Can NAICS 541330 be used for construction work?
No, NAICS 541330 is for engineering services like design and consulting, not actual construction. Construction uses codes in the 236xxx and 237xxx ranges. Engineering and construction are often contracted separately.
Businesses below this threshold in average annual receipts qualify as small businesses for set-aside contracts.
