Her portfolio supports the agency’s core mandate to ensure safe, compliant, and functional environments for personnel and equipment across geographically dispersed units, with a strong emphasis on maintenance, transportation, and facility management contracts. Mangubat maintains established working relationships with a select group of trusted contractors, including KOTRACK INCORPORATED, BRANSCOME OPERATING, LLC, MOTOROLA SOLUTIONS, INC., AMD INTERNATIONAL TECHNOLOGIES LLC, and KOTSUKENSETSU CO., LTD. These partnerships reflect a focus on both domestic and international vendors capable of delivering specialized services in facility systems, communications infrastructure, and technical support. Her contracting approach emphasizes reliability, compliance, and performance-based outcomes, fostering long-term vendor collaboration grounded in clear deliverables and rigorous oversight. Mangubat’s procurement portfolio reflects a consistent preference for full and open competition, with 100% of her awards issued without socioeconomic set-asides. This pattern underscores a mission-driven focus on selecting the most qualified offerors regardless of business size or certification status, prioritizing technical capability and operational readiness over socioeconomic preferences. Her primary procurement focus lies in three NAICS categories: 238320 (Painting and Wall Covering Contractors), 541930 (Translation and Interpretation Services), and 335311 (Power, Distribution, and Specialty Transformer Manufacturing), each representing one-third of her award activity. This balanced specialization highlights expertise in facility maintenance, cross-cultural communication support for multinational operations, and critical electrical infrastructure procurement—demonstrating a unique blend of construction, linguistic, and power systems contracting proficiency.
