Principal Engineering Inc.

Principal Engineering Inc., operating its Principal Infrastructure A / E / C division from Covington, Louisiana, delivers architectural and engineering design services for VA medical center infrastructure and facilities projects exclusively as a Service-Disabled Veteran-Owned Small Business (SDVOSB) prime contractor. The firm holds concurrent SDVOSB and Veteran-Owned Small Business certifications valid through November 2027, competes under 100% SDVOSB set-asides across its federal footprint, and is structured as a Subchapter S corporation with self-certified small disadvantaged business status and American Indian ownership.

Principal Engineering's customer concentration is absolute and narrow. The Department of Veterans Affairs Veterans Health Administration accounts for all 16 recent prime awards and the full $3.9 million in combined potential value across four Veterans Integrated Service Networks (VISNs). VISN 16 (serving Louisiana and Mississippi) anchors the portfolio with 12 awards valued at $2.4 million combined. VISN 9 (Tennessee Valley) placed a recent $1.175 million definitive contract for architectural and engineering design services to replace domestic water and fire mains and backflow devices at the VA Tennessee Valley Healthcare System's York Campus in Murfreesboro, with an ultimate completion date of March 31, 2027. Two smaller awards sit with VISN 17 (Texas) totaling $203 thousand, and one with VISN 7 (Central Alabama) valued at $153 thousand. No federal agencies outside the VA system appear in the recent award record.

Capability work centers on multidisciplinary architectural and engineering design for VA medical center infrastructure modernization. Representative projects include the $1.175 million water and fire mains replacement at the Murfreesboro facility (awarded April 1, 2026), a $610.7 thousand emergency erosion mitigation and drainage design contract at Overton Brooks VA Medical Center in Shreveport (awarded September 17, 2025), a $181.4 thousand catheterization laboratory renovation at Amarillo VA Health Care System (awarded February 22, 2022), and a $152.6 thousand water-tower design and mechanical repair contract at Central Alabama Veterans Health Care System in Tuskegee (awarded February 22, 2023). The portfolio spans NAICS codes 541330 (Engineering Services) and 541310 (Architectural Services), with PSC classifications covering architect-and-engineering services for hospital construction and water supply facilities. Projects require multidisciplinary design expertise including mechanical, plumbing, civil, structural, electrical, and industrial hygiene specializations.

Activity has been intermittent. One award in 2021, one in 2022, one in 2023, a two-year gap through 2024, then two awards in 2025 and one in 2026 (the most recent on April 1, 2026). Three awards valued at $1.8 million combined face ultimate completion within the next twenty-four months, creating recompete exposure. The vendor operates exclusively as a prime contractor; no subcontractor relationships appear in the recent award record. Service Contract Inventory data shows only one SCI record in FY2024, appearing as a named subcontractor rather than a prime, suggesting most Principal Engineering invoicing sits below the $150,000 reporting threshold or operates outside SCI capture. The firm maintains a subsidiary, Principal Lowe Surveying LLC, also designated as SDVOSB and Veteran-Owned, though that entity's federal activity is not detailed in the source material.
