Tierra Scales

Tierra Scales serves as a key procurement professional within the Public Buildings Service’s PBS R11 Construction Services Division Center 1, part of the General Services Administration, where they manage acquisition strategies for mission-critical federal facility modernization projects across the National Capital Region. Responsible for overseeing the full lifecycle of construction-related services, Scales specializes in design-build and integrated project delivery contracts that support historic preservation, infrastructure upgrades, and sustainable building operations. Their work ensures federal facilities meet safety, functionality, and environmental standards while aligning with GSA’s broader mandate to deliver high-performance public infrastructure. Scales collaborates with a diverse array of contractors specializing in administrative management consulting and industrial machinery maintenance, fostering partnerships grounded in technical excellence and regulatory compliance. While no single vendor dominates their portfolio, engagements typically involve firms with demonstrated expertise in federal construction oversight, facility systems integration, and compliance with FAR and GSA-specific acquisition protocols. Relationships are characterized by long-term performance tracking, post-award evaluations, and a preference for contractors with proven experience in federal facility environments. Scales’ procurement activity reflects a strong orientation toward full and open competition, with 100% of acquisitions conducted without set-aside designations. This approach prioritizes technical merit and cost-effectiveness over socioeconomic preferences, indicating a strategic focus on mission outcomes rather than socioeconomic targeting. While small business participation is not formally incentivized through set-asides, contractors of all sizes are evaluated on capability, past performance, and compliance with federal construction standards. The primary NAICS categories under Scales’ purview are 541611 for administrative and management consulting services, supporting project controls and construction program management, and 811310 for commercial and industrial machinery repair and maintenance, ensuring ongoing operational readiness of building systems. Their expertise lies in procuring technical services that enable lifecycle management of federal infrastructure, with deep familiarity in facility systems integration, energy efficiency retrofits, and historic structure rehabilitation.
