3500 Square, LLC

3500 Square, LLC, a minority-owned, veteran-owned, service-disabled veteran-owned, and self-certified small disadvantaged business holding SBA 8(a) Program Participant and HUBZone Firm certifications, competes as a prime contractor on large defense and civilian IT acquisition vehicles and as a subcontractor on military health and transportation modernization programs. The sole proprietorship is based in Utuado, Puerto Rico and competes on full-and-open defense contracts without set-aside protection, despite holding 8(a) and HUBZone eligibility.

3500 Square's recent prime portfolio centers on two major vehicle awards totaling four billion dollars in potential value. The Missile Defense Agency awarded 3500 Square a seat on the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) multiple-award IDIQ in December 2025, a $151 billion research-and-development and prototyping vehicle supporting multi-domain defense systems, ballistic and hypersonic missile defense, and cybersecurity modernization with performance across Huntsville, Alabama and other locations designated by task orders. The company received an initial $500 task order under SHIELD on the same date. The Naval Sea Systems Command awarded 3500 Square a Seaport Next Generation (Seaport-NXG) multiple-award IDQ in January 2025, a $4 billion vehicle through January 2029 focused on facilities support services and naval systems engineering for NAVAIR, NAVWAR, NAVFAC, NAVSUP, the Office of Naval Research, and the Marine Corps, with an initial $500 minimum guarantee task order awarded in March 2025. 3500 Square also holds a GSA Federal Supply Schedule contract awarded October 2024 for IT Professional Services and Health Information Technology Services, with a $500 thousand ceiling through October 2029, covering 44 unique labor categories spanning IT and health IT roles at hourly rates from $43.10 to $139.06, requiring education from associate to bachelor's degree with no security-cleared positions offered. Representative categories include IT Test Analyst, Health IT Delivery Consultant, Health Systems Engineer, Database Management Specialist, and IT Subject Matter Expert Level III, reflecting technical and healthcare-focused labor positioning.

Customer concentration sits with the Department of the Navy Naval Sea Systems Command, which anchors 88% of awards and 100% of combined potential value through the Seaport-NXG vehicle. The Missile Defense Agency, the General Services Administration, the Department of Transportation, and the Defense Health Agency complete the customer set. Activity has grown from one award in 2023 to four in 2025, with two awards received in the first five months of 2026. 3500 Square's obligated dollars total $5.8 million across four billion in potential value, reflecting early-stage vehicle participation and minimal task-order flow to date.

In its subcontractor role, 3500 Square delivers military family support services under a Military OneSource employee-assistance contract (award date May 2026), discretionary grants lifecycle management and transparency-dashboard development to ICF Incorporated on a Department of Transportation modernization sub-task (January 2026), and digital-first military health system support to Leidos on an MHS Genesis sub-task (December 2023). The subcontract portfolio reflects health-sector, federal-IT, and military-family-services capabilities routed through mid-market primes.
