→DoD accounts for 70% of all 541330 spending ($25.1B of $35.7B) — driven by naval ship engineering (Electric Boat), aircraft systems (Lockheed, Northrop), and missile programs (Raytheon).
→GSA's $4.6B reflects A-E (Architect-Engineer) services for federal facilities — a more distributed and accessible segment for mid-tier engineering firms under Brooks Act qualification-based selection.
→DOT's 3,438 awards cover transportation infrastructure engineering — bridge design, environmental engineering, and ITS (intelligent transportation systems) — with strong small business set-aside usage.
→Average award value of $687K is one of the lower thresholds for engineering NAICS codes at the task-order level, despite large-prime dominance in weapons program engineering above $100M.
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 $35.7B under NAICS 541330 in the trailing 12 months (Apr 2025–Mar 2026) across 51,962 awards. DoD dominates at $25.1B, followed by GSA ($4.6B), DOT ($1.25B), DHS ($1.3B), and NASA ($724M). Source: PrimeRFP SCOUT, obligations_only, ≥$100K 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.
