Sean P. Sackett

Sean P. Sackett serves as a Contracting Officer for W2SN Endist Japan under the Department of the Army, responsible for managing the acquisition of critical infrastructure projects that sustain and modernize U.S. military installations across the Indo-Pacific region. He oversees the full lifecycle of construction and civil engineering contracts, ensuring compliance with federal procurement regulations while aligning acquisitions with the agency’s mission to enhance force readiness and quality of life for service members and their families. His portfolio primarily includes commercial and institutional building construction, as well as heavy civil engineering projects such as utilities, roads, and site development for Army and Air Force facilities. Sackett maintains long-standing relationships with a select group of experienced contractors, including L1 Enterprises Incorporated, Gilbane Federal, Toyo Construction Co., Ltd., and the Maeda-Samsung-KGC-Onaka Joint Venture, reflecting a preference for established firms with proven track records in overseas military construction. His procurement approach emphasizes performance reliability, regulatory adherence, and timely delivery in complex operational environments. He frequently engages joint ventures and international contractors with demonstrated expertise in U.S. military standards and Japan-based construction logistics. Sackett’s contracting activity is entirely non-set-aside, with 100% of awards issued under full and open competition. This reflects a strategic emphasis on leveraging the broadest possible pool of qualified vendors to meet mission-critical timelines and technical requirements, rather than socioeconomic set-asides. While small business participation is not formally prioritized in his portfolio, all procurements remain fully compliant with FAR and DoD acquisition policies. His primary focus lies in NAICS 236220 (Commercial and Institutional Building Construction), encompassing barracks, family housing, maintenance shops, and administrative facilities, supplemented by NAICS 237990 (Other Heavy and Civil Engineering Construction) for site infrastructure and utilities. He possesses deep technical expertise in military construction standards, facility sustainment, and international contracting frameworks governing U.S. forces in Japan.
