→DoD accounts for 75% of all 541330 spending ($257B of $340B) — driven by naval ship design (Electric Boat), aircraft systems (Lockheed, Northrop), and missile programs (Raytheon).
→GSA's $34.3B at 1,357 awards reflects AE (Architect-Engineer) services for federal building projects — a more distributed and accessible segment for mid-tier engineering firms.
→DOT's 1,608 awards cover transportation infrastructure engineering — bridge design, environmental engineering, and ITS (intelligent transportation systems) — with strong small business set-aside usage.
→The top 3 awardees (Electric Boat, Lockheed, Raytheon) hold $59.5B of $340B — 17% of total. The remaining 83% is spread across hundreds of engineering firms, making this NAICS highly competitive below the prime tier.
Frequently Asked Questions — NAICS 541330
What types of federal contracts use NAICS 541330?
NAICS 541330 covers engineering services contracts including systems engineering, program management support, weapons system design, naval architecture, aerospace engineering, environmental engineering, civil engineering for infrastructure, and military facilities design. It is used across DoD, NASA, GSA's AE program, and DOT infrastructure projects.
How much does the federal government spend on NAICS 541330?
Federal agencies obligated approximately $340.4B under NAICS 541330 in the trailing 12 months (Apr 2025–Mar 2026) across 28,858 awards. DoD dominates at $257.2B, followed by GSA ($34.3B), NASA ($9.5B), DOT ($8.1B), and DHS ($8.1B). Source: PrimeRFP SCOUT, ≥$25K floor.
Can mid-tier engineering firms compete in NAICS 541330?
Yes, particularly for GSA AE (Architect-Engineer) services, DOT infrastructure programs, and DoD support services below the weapons system level. GSA uses Brooks Act selection procedures for AE work (qualifications-based, not lowest price). DoD uses set-asides for smaller engineering support task orders. OASIS+ professional services pools also carry significant 541330 volume.
What is the size standard for NAICS 541330?
The SBA size standard for NAICS 541330 is $25.5M in average annual receipts. However, for contracts that are predominantly professional services, the $25.5M revenue threshold applies. Many DoD 541330 programs use the "manufacturing" size standard ($47M) or are full-and-open due to the specialized nature of weapons system engineering.
