Rachael Zack

Rachael Zack supports the IBC Acquisition Services Directorate within the Department of the Interior’s Departmental Offices, managing specialized procurement activities critical to federal land management and resource stewardship. She oversees the acquisition of professional and technical services that enable real estate valuation, aviation logistics, scientific research, and systems design for public trust assets. Her portfolio centers on securing expert support to maintain infrastructure integrity and modernize land management operations, with a focus on high-precision, mission-critical contracts requiring technical depth and operational reliability. She plays a pivotal role in aligning acquisition strategies with the agency’s broader mission to sustain federal landholdings through data-driven, performance-based contracting. Rachael maintains consistent working relationships with a select group of specialized contractors, including Phoenix Air Group, Inc., Papillon Airways Inc., Brainerd Helicopters, Inc., HMC Helicopter Service LLC, and Mathematica Inc. These partnerships reflect a preference for niche providers with proven capabilities in aviation support, geospatial analysis, and technical consulting. Her contracting patterns emphasize long-term, performance-based engagements over transactional purchases, fostering collaborative relationships with vendors who deliver specialized, mission-critical services under complex operational constraints. Her procurement approach prioritizes open competition, with 85.7% of awards issued under no set-aside conditions, reflecting the highly specialized nature of the services required. However, she consistently allocates 14.3% of awards to Indian Small Business Economic Enterprise (ISBEE) set-asides, demonstrating a targeted commitment to tribal economic development aligned with the Department of the Interior’s trust responsibilities. Rachael’s primary procurement focus lies in NAICS 541519 (Other Computer Related Services), which accounts for 71.4% of her activity, followed by computer systems design (541512) and management consulting (541611). She routinely acquires data analytics, software development, systems integration, and operational support services tailored to land management platforms, environmental modeling, and aviation logistics systems, reflecting deep expertise in technical domains supporting federal land stewardship.
