Dayna Omiya serves as a key procurement professional within the DSC Contracting Services Division of the National Park Service, overseeing the acquisition of engineering, architectural, and heavy civil construction services critical to preserving and modernizing the nation’s park infrastructure. Responsible for managing complex, mission-critical contracts, she ensures compliance with federal acquisition regulations while advancing the agency’s goals of historic preservation, utility system resilience, and visitor facility enhancement across ecologically sensitive and remote landscapes.

Omiya maintains longstanding relationships with top-tier engineering and construction firms including AECOM Technical Services, Inc., Vanasse Hangen Brustlin, Inc., Johnson, Mirmiran & Thompson, Inc., HDR Engineering Inc., and McKenzie Construction & Site Development LLC. These partnerships reflect a preference for firms with proven experience in federal environmental projects, historic structure rehabilitation, and water/sewer infrastructure upgrades.

Her procurement patterns show a strong emphasis on open competition, with 88.9% of awards issued without set-aside restrictions. When small business participation is pursued, it is evenly split between Indian Small Business Economic Enterprise (ISBEE) and Total Small Business Set-Aside (FAR 19.5) mechanisms, reflecting targeted support for eligible small entities within the Department of the Interior’s unique socioeconomic framework.
