About the company
CB Contracting Inc., doing business as K12 Defense, is a woman-owned small disadvantaged business based in Mesa, Arizona, that specializes in active vehicle barrier systems installation, maintenance, repair, and retrofitting for federal facilities. Operating exclusively as a prime contractor (100% of recent awards), K12 Defense competes under the Total Small Business set-aside across all federal work. The company is a Subchapter S corporation structured as a for-profit organization with self-certified small disadvantaged business status.
K12 Defense's capability portfolio centers on physical security infrastructure, predominantly active vehicle barrier maintenance and repair. Recent representative work includes a $221,284 definitive contract with the General Services Administration's Public Buildings Service to design, furnish, and install a four-unit M50-rated automatic retractable electric bollard system at the Lloyd D. George U.S. Courthouse in Las Vegas, Nevada (completed September 2026); an $11,195 definitive contract with Naval Facilities Engineering Command Hawaii to repair and perform preventive maintenance on vehicle barrier systems retrofitted with K12 Defense actuators at Pearl Harbor (June 2025); and a $24,275 BPA call from Air Education and Training Command for vehicle barrier repair at Lightning Gate, Luke Air Force Base, Arizona (June 2026). K12 Defense also manufactures and supplies barrier components — a June 2025 purchase order from TACOM Life Cycle Management Command for six tire spike systems valued at $11,199.
Customer concentration skews toward Air Force commands. Air Combat Command accounts for ten awards ($1.3 million combined potential value), anchored by a $999,999 single-award Indefinite Delivery Contract running through November 2029 for preventive maintenance and repair of vehicle barrier systems at Davis-Monthan Air Force Base. That IDC has generated seven delivery orders since December 2024, ranging from $4,399 to $56,802. Air Mobility Command rounds out the top customer by potential value at $3.3 million across three awards. The top five customers by award count cover 59% of all awards; the top five by potential value cover 86%, reflecting a concentration in Air Force basewide maintenance vehicles and larger civilian construction projects.
K12 Defense holds a $249,999 Blanket Purchase Agreement with Air Education and Training Command (award date June 23, 2025, performance through June 30, 2030) covering active vehicle barrier systems installation, maintenance, repair, and retrofitting at federal facilities nationwide. The Davis-Monthan IDC ($999,999) and a Multiple Award Schedule position (three task orders, $525,000 combined potential value) round out the vehicle footprint. Award activity has accelerated — one award in 2020, four in 2021, then two in 2024 rising to seven in 2025 and four in 2026 — though the footprint remains small, with combined potential value of $7.1 million across 32 total awards. Three awards valued at $279,000 reach ultimate completion within the next twenty-four months and face recompete exposure. The vendor's work spans electronic and precision equipment repair (10 awards), security systems services (9 awards), and miscellaneous metal product manufacturing (4 awards) by NAICS classification.
