Maconnerie Batiment Services

Maconnerie Batiment Services (MBS), a for-profit partnership based in Garches, France, delivers construction, renovation, and facility maintenance services to the U.S. Department of State as a prime contractor, operating exclusively on full-and-open competitive awards without set-aside designation. MBS competes on technical capability and pricing for maintenance and infrastructure work at U.S. diplomatic facilities in France and elsewhere.

MBS's customer footprint is consolidated within the Department of State. The Bureau of Overseas Building Operations accounts for 14 of 19 awards (100% of combined potential value coverage across all four customer agencies), representing $1.1 million in combined potential value. The Bureau of European and Eurasian Affairs has placed 3 awards ($55 thousand combined), with the Bureau of Consular Affairs and the Bureau of African Affairs each contributing 1 award ($44 thousand and $23 thousand respectively). All ranking signals — by award count and by potential value — align at Overseas Building Operations as the single dominant customer.

MBS's work centers on renovation, maintenance, and facility improvements at U.S. consular and diplomatic properties. Recent representative contracts include a $44.2 thousand firm-fixed-price purchase order from the Bureau of Consular Affairs for consular kitchen renovation awarded September 11, 2026, with performance in France and completion December 29, 2026; a $109.4 thousand firm-fixed-price order from the Bureau of Overseas Building Operations for renovation of common spaces in residential compounds awarded August 1, 2025, completing December 31, 2025; a $51 thousand order from Overseas Building Operations for carpet replacement in Consular Services facilities awarded September 26, 2025; and a $49.3 thousand order for furnish and replacement of false ceiling tiles in consular offices awarded April 28, 2025. Earlier work included bathroom and toilet facility renovation ($45.5 thousand, April 2024), kitchen and pantry renovation at Leopold II ($29.4 thousand, September 2022), and shutter painting ($18.1 thousand, September 2023). The vendor's NAICS footprint reflects this scope: Residential Remodelers and Other Services to Buildings and Dwellings account for 6 awards each, with smaller volumes under Masonry Contractors and Flooring Contractors.

Activity has been modest and episodic — one award in 2022, one in 2023, two in 2024, three in 2025, and one in the current year — with combined potential value of $1.2 million fully obligated. One award ($44 thousand) reaches ultimate completion within the next twenty-four months and therefore faces recompete exposure. MBS operates exclusively as a prime contractor with no subcontract footprint; all 19 awards are direct prime contracts. The vendor maintains no presence on government-wide acquisition vehicles, IDIQs, or agency-wide BPAs — all awards are individual purchase orders under full-and-open competition.
