About Meccs Mitomo JV
Meccs Mitomo JV is a Japan-based corporate joint venture between Meccs Corporation and Mitomo Corporation, both Japanese companies, that serves as a prime contractor for the U.S. Department of Defense across multiple service branches. Registered in SAM.gov since March 2013, the entity specializes in infrastructure support, facilities maintenance, HVAC services, construction, and design-build projects at U.S. military installations throughout Japan. With a UEI of LWAKPMWHD1B4 and headquarters in Tokyo, Meccs Mitomo JV has established itself as a critical infrastructure partner for the Department of Defense, holding several significant indefinite delivery contracts totaling over $770 million in combined capacity.
Meccs Mitomo JV has delivered a comprehensive range of services through federal contract awards spanning multiple Department of Defense agencies. The company has received numerous delivery orders for preventive maintenance and inspection (PMI) services for HVAC systems at Navy installations, including work at Commander Fleet Activities Japan, Yokosuka Naval Base, and various other Navy facilities. Beyond HVAC maintenance, Meccs Mitomo JV has performed non-recurring repair work including replacement of chiller units, air conditioning systems, dust collection equipment, cooling towers, and related mechanical components. The company has also executed substantial construction and infrastructure projects, including the construction of base resiliency storage infrastructure at Atsugi Air Base, replacement of power cables and conduits at ammunition piers, modernization of truck fill stands, installation of standby generators, stormwater line upgrades, floor slab repairs, building exterior repairs, and electrical vehicle supply equipment installation at various military bases. Funding for these awards has been provided by the Navy Installations Command, Naval Facilities Engineering Command, Naval Sea Systems Command, U.S. Marine Corps, U.S. Army Pacific Region, and Pacific Air Forces. All contract awards to Meccs Mitomo JV have been issued without small business set-aside designations, allowing the company to compete on a full and open basis. Recent notable delivery orders include a $4.25 million Air Force award for base resiliency storage construction at Atsugi Air Base, a $1.43 million Army award for services in Japan, and multiple Navy awards ranging from tens of thousands to millions of dollars for HVAC maintenance and repair services.
Meccs Mitomo JV holds three significant Indefinite Delivery Contracts with the Department of Defense. The first is a $25.192 million single-award Navy Installations Command contract for preventive maintenance and inspection services for HVAC systems at Naval Base Yokosuka and other Navy installations in Japan, with a performance period through March 31, 2026. This contract allows the Navy to issue task orders for both recurring HVAC maintenance and non-recurring repair or alteration work as required. The second IDC is a $250 million multiple-award contract awarded by the Marine Corps on August 21, 2024, for design-build and design-bid-build construction projects at Marine Corps Air Station Iwakuni, with a performance period extending through August 2029. This contract supports small-magnitude projects ranging from $3,000 to $25 million, with a guaranteed minimum of $500,000 upon award. The third IDC is a $495 million multiple-award construction contract also awarded by the Marine Corps on June 30, 2023, for design-build and design-bid-build construction projects at MCAS Iwakuni, with a performance period through June 2031. Both Marine Corps contracts fall under larger parent IDIQ vehicles supporting construction modernization initiatives at the Iwakuni installation. Under these IDVs, the company has received task orders for diverse infrastructure work including mechanical equipment replacement, power distribution upgrades, generator installation, building renovations, and utility system improvements. None of the IDVs are set aside for small business concerns, reflecting Meccs Mitomo JV's status as a full and open competition contractor capable of executing large-scale infrastructure projects for the Department of Defense.
