Andrew Tierney

Andrew Tierney serves as a key procurement lead within the Stewardship Contracting Branch of the U.S. Forest Service, overseeing the execution of landscape-scale stewardship contracts designed to advance ecological restoration and wildfire risk reduction. He manages acquisitions that integrate timber harvesting with watershed protection, habitat improvement, and infrastructure maintenance, ensuring alignment with the agency’s mission of sustainable forest stewardship. His portfolio consists primarily of service-based contracts under NAICS 115310, focusing on support activities for forestry that require technical expertise in silvicultural practices, fuel reduction, and ecological monitoring. Tierney’s work directly enables the Forest Service to achieve long-term land management goals through performance-based contracting mechanisms that prioritize outcomes over inputs. Tierney maintains consistent working relationships with a core group of experienced contractors, including Brink Brothers Inc., Peak Engineering LLC, AZ Hammer Down, LLC, Gabino D. Grano, and Gladhart LLC. These firms are recognized for their specialized capabilities in forest restoration, heavy equipment operations, and ecological site rehabilitation. His contracting approach favors vendors with proven field experience in complex, multi-objective projects that demand coordination between timber harvest, erosion control, and trail or road maintenance. These partnerships are built on demonstrated technical proficiency and reliability in delivering ecologically sound outcomes under challenging terrain and environmental constraints. Tierney’s procurement activity reflects a strong preference for open competition, with 100% of awards issued under no set-aside provisions. While he does not prioritize socioeconomic set-asides such as 8(a), HUBZone, or SDVOSB programs, his focus remains on securing the highest technical capability and operational readiness to meet mission-critical restoration objectives. This approach ensures that contract performance is driven by expertise in forest management rather than socioeconomic criteria. His primary procurement focus is NAICS 115310—Support Activities for Forestry—encompassing services such as prescribed burning, mechanical thinning, invasive species control, and post-harvest site rehabilitation. Tierney’s technical expertise lies in contracting for ecological restoration projects that require precise adherence to environmental regulations and adaptive management protocols, ensuring that all acquisitions contribute to resilient, fire-adapted forest ecosystems.
