Kosaka Komuten Co., Ltd. has provided an exceptionally diverse portfolio of construction and maintenance services through its federal contract awards, all issued by the Pacific Air Forces without set-aside designations in open market competitions. The company's service offerings have encompassed specialized facility construction projects including a T-10 hush house with foundation and infrastructure support valued at $4.4 million, comprehensive renovation of Junior Non-commissioned Officer housing units totaling $12.2 million with roof replacement, interior and exterior renovations, and upgrades to electrical, plumbing, HVAC, fire suppression, and smart metering systems.

Beyond major construction efforts, Kosaka Komuten has delivered recurring maintenance services encompassing wood flooring installation and repair at military family housing units, carpet replacement services for residential facilities, vehicle barrier maintenance, parking lot repairs, and overhead electrical power repairs. The contractor has also performed specialized services such as crane hoist inspection and performance testing, building demolition, and sewer and water infrastructure work. All of these contracts have been competitively awarded by the Pacific Air Forces with no small business set-aside designations applied, reflecting the contractor's ability to compete effectively in the open federal contracting marketplace for both large-scale construction projects and smaller maintenance task orders.

The first is a multiple award Indefinite Delivery/Indefinite Quantity construction contract awarded on January 13, 2025, with a $990 million ceiling value and performance period extending through January 12, 2035.
