Sandra J Siiberg

Sandra J. Siiberg serves as a Contract Administrator responsible for managing the full lifecycle of federal procurement actions, from solicitation through contract award and administration. She ensures compliance with federal acquisition regulations and supports mission-critical infrastructure and utility initiatives by executing competitive, transparent, and efficient contracting processes. Her portfolio primarily encompasses technical acquisitions in electrical systems, specialty construction, and power distribution services, requiring a strong grasp of performance-based contracting and technical evaluation methodologies. Siiberg plays a vital role in aligning procurement outcomes with operational needs, ensuring timely delivery of essential components and services to support public infrastructure. Her contractor relationships are diverse, engaging with manufacturers, specialty trade contractors, and electrical systems providers across the private sector. While no single vendor dominates her award profile, she consistently works with firms possessing the technical capacity to deliver complex electrical components, power distribution infrastructure, and specialized construction services. Her approach emphasizes vendor reliability, regulatory compliance, and performance accountability, fostering long-term partnerships grounded in clear contract terms and rigorous oversight. Siiberg’s contracting patterns reflect a strong preference for full and open competition, with 100% of her awards issued without set-aside designations. This indicates a focus on maximizing market participation and selecting the most qualified offerors regardless of socioeconomic status, rather than prioritizing 8(a), HUBZone, or SDVOSB programs. While small business participation is not formally incentivized in her portfolio, her processes remain compliant with all applicable socioeconomic requirements. Her primary procurement focus lies in NAICS 335999 (miscellaneous electrical equipment manufacturing), 221122 (electric power distribution), and 238990 (other specialty trade contractors), with additional activity in glass, glazing, and roofing contracting. She specializes in procuring custom electrical components, utility-scale power delivery systems, and integrated construction services requiring precise technical specifications and stringent quality controls. Her domain expertise centers on infrastructure resilience and electrical system modernization.
