Kg-Bauunternehmung, a German construction and infrastructure services company headquartered in Kaiserslautern, Germany, operates as a prime contractor delivering facility repair, maintenance, alteration, and environmental remediation services to U.S. Air Force installations across Europe on a full-and-open competitive basis, with no SBA set-aside designations. The vendor competes exclusively outside set-aside categories and operates as a for-profit organization registered as a federal contractor since November 2004.

Capability scope centers on heavy civil and specialty construction work including water line repair and replacement, runway repair and mill-and-overlay, HVAC system replacement and upgrades, electrical system work, roof repair and restoration, hazardous waste disposal and environmental remediation, infrastructure ground preparation and drainage repair, and facility alteration services. Representative recent work includes a $5.46 million runway repair and mill-and-overlay delivery order at Ramstein Air Base (November 2025), a $3.7 million environmental remediation and soil remediation delivery order at site TYFR0603 (January 2026), a $3.67 million facility modification and repair delivery order (September 2025), and a $1.49 million water line repair and replacement delivery order at New York Avenue, Illinois Boulevard, and Lincoln Boulevard (April 2026).

Customer concentration is extreme and singular.

The Department of the Army Installation Management Command Europe Region places 43 awards worth $11.2 million combined potential value, and Defense Finance and Accounting Service rounds out the top three with 51 awards worth $6.4 million. The vendor's entire portfolio is OCONUS-focused; all work is performed in Germany at Ramstein Air Base, Spangdahlem Air Base, and other installations within the Kaiserslautern Military Community region.

The vendor holds a seat on the primary parent vehicle: the Kaiserslautern Military Community, Ramstein and Spangdahlem Air Bases Multiple Award Construction Contract (MACC), a $950 million indefinite delivery vehicle awarded July 22, 2025, running through July 21, 2034. This contract framework has generated 80 task orders worth $61.5 million combined potential value.

All delivery orders under these vehicles have been awarded on a firm fixed-price, full-and-open competition basis.

Activity has been substantial and consistent over the past five years—13 awards in 2022, eight in 2023, 26 in 2024, 18 in 2025, and four to date in 2026—with a long contracting history dating to 1993 in source data. Within the next twenty-four months, seven awards with combined potential value of $18.4 million face ultimate completion and will require recompete. Work categorization aligns with the vendor's service scope: 321 awards fall under Other Heavy and Civil Engineering Construction (NAICS 237), 123 under All Other Specialty Trade Contractors (NAICS 238), and 103 under Commercial and Institutional Building Construction (NAICS 236). Purchase Service Codes emphasize Maintenance of Office Buildings (160 awards), Maintenance, Repair, Alteration and All Other (136 awards), and Maintenance, Repair, Alteration of Miscellaneous Buildings (134 awards).

The vendor holds three sub-award relationships with Vectrus Federal Services GMBH, dated September 2024, January 2024, and September 2023, indicating a secondary role on Vectrus primes serving USAFE installations. Only 3 of 607 total awards are subcontract awards; the footprint is dominated by prime activity. Obligated dollars total $197.1 million against a combined potential value ceiling of $1.98 billion, representing 10% utilization of authorized contract ceilings.
