Sean P. Sackett

Sean P. Sackett serves as a Contracting Officer for the W2SN Endist Japan under the Department of the Army, responsible for managing the full lifecycle of construction and facility modernization contracts critical to sustaining U.S. military operations across the Indo-Pacific region. He oversees the acquisition of commercial and institutional building construction services to support housing, hangars, maintenance facilities, and institutional infrastructure for Army and Air Force personnel and their families. His procurement activities align with the agency’s strategic mission to enhance force protection and operational readiness through resilient, mission-critical infrastructure development. Sackett manages complex, high-stakes construction contracts requiring strict adherence to military standards, environmental compliance, and international coordination under U.S.-Japan defense agreements. Sackett maintains long-standing relationships with a core group of experienced contractors, including L1 Enterprises Incorporated, Maeda-Samsung-KGC-Onaka Joint Venture, ICHIKEN CO., LTD., Gilbane Federal, and Toyo Construction Co., Ltd. These partnerships reflect a preference for established, technically capable firms with proven experience in large-scale, multi-phase construction projects in Japan’s unique regulatory and logistical environment. His contracting approach emphasizes performance-based outcomes, risk mitigation, and contractor accountability, fostering collaborative relationships built on reliability and compliance with U.S. Army Corps of Engineers standards. Sackett’s procurement portfolio reflects a 100% non-set-aside strategy, with no utilization of 8(a), HUBZone, SDVOSB, or other socioeconomic set-asides. This reflects the operational necessity of procuring large-scale, specialized construction services that require advanced technical capabilities, international supply chain coordination, and pre-qualified contractor credentials typically held by larger, established firms with global experience in military infrastructure. His primary focus is on NAICS 236220—Commercial and Institutional Building Construction—encompassing the design-build, renovation, and new construction of facilities meeting stringent DoD architectural and engineering specifications. Sackett’s expertise lies in managing complex construction projects involving structural integrity, utility integration, seismic resilience, and compliance with both U.S. military and Japanese building codes, ensuring infrastructure meets enduring operational requirements in a high-risk geographic theater.
