SIGMA PSI CONSULTING, MECHANICAL, ELECTRICAL AND PLUMBING ENGINEER, PLLC

SIGMA PSI CONSULTING, MECHANICAL, ELECTRICAL AND PLUMBING ENGINEER, PLLC specializes in integrated mechanical, electrical, and plumbing (MEP) engineering services for federal facility modernization, with a demonstrated focus on design-phase support for healthcare infrastructure. The firm delivers construction-period design services that bridge schematic design with field implementation, ensuring compliance with ADA, NFPA, and ASHRAE standards in mission-critical environments. Their technical expertise includes HVAC system optimization, electrical distribution redesign, plumbing code compliance, and coordination of building systems during active renovation projects—particularly in veteran healthcare facilities. A key differentiator is their service-disabled veteran-owned status, which aligns their mission with the Department of Veterans Affairs’ goals for accessible, resilient, and patient-centered care environments. The contractor has delivered services exclusively to the Department of Veterans Affairs, providing architectural and MEP engineering support for the renovation of Community Living Center facilities. Their work directly supports VA’s capital improvement priorities, focusing on functional upgrades to aging infrastructure while maintaining operational continuity during construction. This sustained engagement reflects a deep understanding of VA’s regulatory frameworks, design standards, and the unique needs of veteran healthcare populations. While primarily classified under NAICS 541330 for MEP engineering, the firm’s awarded work falls under NAICS 541310 for architectural services, indicating a specialized role in architectural coordination and systems integration rather than pure design. This positions them as a technical partner in multidisciplinary renovation teams, emphasizing systems interoperability and code compliance over schematic design. As a small, service-disabled veteran-owned business based in Castleton, Vermont, SIGMA PSI CONSULTING leverages its certification to serve federal clients with a mission-aligned perspective. Their geographic presence supports regional federal projects, with a clear focus on the VA’s national healthcare infrastructure portfolio.
