Sigma is a Service-Disabled Veteran-Owned Small Business (SDVOSB) delivering high-impact solutions in construction, water treatment, federal contracting, and workforce services. Our team brings decades of experience operating in complex domestic and international environments, with a focus on quality, compliance, and mission success.
Sigma Group USA provides comprehensive project management services for federal construction, renovation, facility modernization, and infrastructure projects. We serve as the single point of accountability from award through closeout, ensuring every phase of the project is planned, coordinated, documented, and executed in accordance with contract requirements.
Our project managers combine operational leadership, government contracting expertise, and disciplined execution to keep projects on schedule, within budget, and fully compliant with federal regulations. We understand that successful federal projects require far more than construction expertise. They demand proactive communication, rigorous documentation, safety oversight, quality control, and strict adherence to FAR, VAAR, OSHA, Davis-Bacon, and agency-specific requirements.
Whether managing self-performed work or coordinating specialized subcontractors, Sigma maintains complete oversight of project execution while providing our clients with clear communication, transparency, and responsive decision-making throughout the life of the contract.
