Federal contract history
| Fiscal year | Obligated, prime contracts |
|---|---|
| FY2024 | -$271,345 |
| FY2025 | $638,092 |
| FY2026 (incomplete) | $1.2 million |
FY2026 ended September 30, and its year-end contract reports and corrections are still arriving, so it's marked incomplete until about early January 2027.
These are every prime contract USAspending.gov records under UEI KKMXN5FVNCM9, from its award search. For a company that is part of a parent company, USAspending's recipient page can show a different figure for a year, because it counts the company's own record and its parent's record separately.
A negative year means cuts to older contracts (de-obligations, often when work finishes under budget or is descoped) took off more than new awards added.
Its biggest federal customers since fiscal year 2024: Department of Veterans Affairs ($1.5 million).

How to check or correct this record
The file sometimes leaves a certification out, and a newer one won't be in it yet. Self-reported business types are what the firm says about itself on SAM.gov; they aren't SBA certifications. This page doesn't show SBA's VetCert certification for veteran-owned firms; SBA's search below does.
Check or correct this record at the source: open its SAM.gov entry, or search UEI KKMXN5FVNCM9 () in SAM.gov's entity search (free sign-in) and in SBA's Small Business Search (formerly DSBS), which shows SBA certifications including VetCert. The business can update its details in its SAM.gov registration and its certifications at certifications.sba.gov.

Open contracts in Principal Engineering Inc's NAICS codes
658 open federal opportunities on SAM.gov use one of Principal Engineering Inc's NAICS codes and may be open to it: no set-aside, or, in the codes it is registered small under, a small business set-aside or one for a status it reports about itself on SAM.gov (service-disabled veteran-owned). Here are a few, those in its primary code first (none of these are in Louisiana right now), then the soonest due.
Confirm eligibility first. Principal Engineering Inc's service-disabled veteran-owned status is self-reported on SAM.gov, and this page can't confirm an SBA certification for it, so set-asides for it may be relevant but may not be open to it: SDVOSB and VOSB set-asides need SBA VetCert certification.
