CALHOUN INTERNATIONAL, LLC

CALHOUN INTERNATIONAL, LLC specializes in delivering engineering and professional technical services to federal defense stakeholders, with a focus on systems support, property management compliance, and mission-critical infrastructure modernization. Their core capabilities include engineering analysis, government-furnished property clause administration, and technical documentation updates within complex DoD acquisition environments. The firm demonstrates deep familiarity with DoD contracting frameworks, particularly in managing contractual modifications related to asset accountability, logistics coordination, and technical specification alignment. Their expertise lies in ensuring regulatory adherence and operational continuity through precise contract administration and technical oversight, making them a trusted partner for agencies requiring meticulous compliance with federal property and procurement standards. The company maintains a consistent relationship with the Department of Defense, providing services under long-term indefinite-delivery/indefinite-quantity (IDIQ) vehicles such as SEAPORT-NXG. Their work supports defense logistics, systems sustainment, and acquisition lifecycle management, often involving the refinement of contractual language to reflect evolving operational requirements and federal property protocols. This sustained engagement suggests a pattern of repeat performance and trusted advisory status within DoD procurement channels. CALHOUN INTERNATIONAL operates primarily under NAICS 541330 (Engineering Services) and 541990 (Other Professional, Scientific, and Technical Services), reflecting a niche focus on technical contract administration and engineering support rather than design or R&D. Their market positioning centers on bridging technical execution with regulatory compliance in defense acquisition systems, serving as a specialist in the intersection of contractual precision and operational readiness. As a Service-Disabled Veteran-Owned Business headquartered in Tampa, Florida, the company leverages its certification to align with federal small business goals while maintaining a lean, agile structure optimized for responsive government contracting. Their geographic presence supports national defense missions with a focus on efficiency, compliance, and mission-aligned service delivery.
