Serrano Proano Diseno Y Construccion S.A.

Serrano Proano Diseno Y Construccion S.A., doing business as Serrano Proano, is an Ecuador-based construction and design firm that operates as a prime contractor delivering vertical and horizontal building construction, infrastructure repair, and site work to the Department of the Army, the Department of the Navy, the Department of State, and subordinate regional commands throughout Central America, South America, and Panama. The company is a subsidiary of PC Brothers Company and competes under full-and-open procurement with no small business set-aside designation across its federal footprint.

Serrano Proano's customer concentration is heavily weighted toward Army construction vehicles. The top five funding agencies (by both award count and potential value) represent 89% of recent awards and 98% of combined potential value. The Department of the Army Corps of Engineers accounts for $236.3 million across three awards (primarily two recently awarded IDIQs), with the Engineering District Mobile adding an additional $208.2 million across 25 delivery orders. Army Southern Command has placed five orders worth $54.4 million combined. The Department of the Navy Bureau of Medicine and Surgery and the Department of State's Bureau of Overseas Building Operations round out the active customer set with naval medical facility repairs and embassy property work. The portfolio spans Peru, Ecuador, Argentina, Panama, Guatemala, Honduras, El Salvador, and Belize.

Serrano Proano holds three substantial indefinite delivery contracts anchoring its regional work: a $99 million multiple-award MATOC for design-build and construction in Central America (awarded July 2026, ultimate completion July 2031); a $20 million single-award Peru IDIQ for small construction services (awarded September 2024, completion September 2029); and a $49 million multiple-award South America and Panama MATOC (awarded June 2023, completion June 2028). Representative delivery orders include a $316.7 thousand firm-fixed-price award for design and construction of CCTV cameras and lighting at NAMRU South Naval Hospital in Iquitos, Peru (September 2025); a $3.54 million firefighting emergency operations center in Argentina (October 2024); a $2.12 million indigenous school facility in the Galapagos (September 2025); a $357.1 thousand repair to Building 9 at NAMRU-S Callao (September 2025); and a $312.6 thousand staff housing construction oversight for the U.S. Embassy Quito (July 2024). The vendor executes all awards as prime with no subcontractors, focusing work on NAICS 236220 (commercial and institutional building construction) and PSC construction-of-miscellaneous-buildings tasks.

Activity has accelerated in recent years, with two awards in 2022 to six in 2025 and two delivered year-to-date through mid-2026. Combined potential value across 55 prime awards reaches $739.2 million, though only $58.8 million (8%) is obligated, reflecting the IDIQ structure and early-stage execution on recently awarded vehicles. Seven awards with ultimate completion dates in the next twenty-four months carry combined potential value of $6.7 million and face recompete exposure. The contractor's regional expertise and established relationships with Army Corps of Engineers Mobile District and Army Southern Command position it as the primary federal construction contractor for U.S. military, naval medical, and embassy facilities across South and Central America.
