Tanaka Gumi Tanaka Construction Konno Kensetsu JV

Tanaka Gumi Tanaka Construction Konno Kensetsu JV, a Japanese construction joint venture headquartered in Aomori, holds a single-award $7 billion Simplified Acquisition of Base Engineer Requirements (SABER) Indefinite-Delivery/Indefinite-Quantity contract with the U.S. Air Force Pacific Air Forces as the primary contractor for facility maintenance, repair, and minor construction services within a 40-kilometer radius of Misawa Air Base, Japan, and operates exclusively as a federal prime contractor with no subcontract footprint.

The joint venture's federal work is concentrated almost entirely on Pacific Air Forces facility operations at Misawa Air Base. Recent delivery orders under the SABER IDIQ include a $1.1 million contract for HVAC system repair at Building 519 (November 2024), a $918 thousand delivery order for AAFES Arts and Crafts facility repairs (March 2025), a $915 thousand vehicle parking garage construction award (November 2024), and a series of $893 million to $1.07 million delivery orders for base resiliency storage facility construction—including fuels, logistics, sortie generation, life support, and emergency readiness-based capital planning (RBCP) storage—all at Misawa through December 2025. Earlier work spans compressed air line repairs, bridge reconstruction, dormitory humidity control system repairs, F-35 hangar and electrical infrastructure work, tower drain system repairs, fire alarm and fire suppression system maintenance, and exterior lighting upgrades. Work scope is firm fixed-price, competitively awarded without set-asides, and performed entirely in Japan.

Customer concentration is extreme. The Department of the Air Force Pacific Air Forces accounts for 97% of the vendor's award count (323 of 379 awards) and 95% of combined potential value ($210.1 million of $220 million). The remaining five customers—the Department of Defense Education Activity (16 awards, $1.9 million), the Department of the Navy Installations Command (13 awards, $3.1 million), the Office of the Secretary of Defense (12 awards, $3.1 million), the Department of the Air Force Materiel Command (4 awards, $354 thousand), and the Department of the Army Space and Missile Defense Command (3 awards, $944 thousand)—are peripheral to the footprint.

The vendor's activity shows modest recent volume. The past five years reflect 35 awards in 2022, 32 in 2023, 34 in 2024, 20 in 2025, and 12 year-to-date in 2026. Combined obligated dollars across all awards stand at $78.8 million against a combined potential value of $220 million, indicating a 36% obligation rate typical of IDIQs with multiple task orders. Only six awards (combined potential value $1.2 million) face ultimate completion within the next twenty-four months, signaling limited near-term recompete exposure relative to the large SABER IDIQ ceiling.

The contractor sits on three parent vehicles. The primary vehicle is the SABER IDIQ contract (FA520524D0001) awarded in October 2023 with a $7 billion ceiling through October 2028, against which 70 task orders totaling $18 million in combined potential value have been issued year-to-date through mid-2026. Two older single-award IDIQs—contract FA520513D0002 (185 task orders, $32.1 million combined potential value) and contract FA520518D0004 (121 task orders, $30.7 million combined potential value)—remain active and represent the majority of the vendor's delivery-order pipeline. Work across all three vehicles is facility maintenance, repair, and minor construction at Misawa Air Base spanning HVAC, electrical, mechanical, structural, fire suppression, and specialized storage infrastructure. The vendor competes no contract work outside Misawa and does not participate in broader Air Force or DoD-wide IDIQs, GWACs, or agency-wide vehicles; its footprint is single-location, single-customer dependent.
