About R2Build
R2Build, a minority-owned small disadvantaged business based in Irvine, California, delivers design-bid-build construction services to the U.S. Army Corps of Engineers as a prime contractor under total small business set-asides. The company operates exclusively as a prime (100% of recent awards) and competes solely under small-business set-asides; no general and open competition or subcontract work appears in the recent record.
R2Build's capability portfolio centers on federal facility construction and infrastructure modernization, specifically commercial and institutional building construction under NAICS 236220. Recent work includes a $18.9 million firm fixed-price definitive contract awarded by the Army Corps of Engineers Sacramento District on May 13, 2026, for design-bid-build construction of new administrative and maintenance facilities at H.L. Englebright Dam and Lake in Smartsville, California — encompassing a 5,000-square-foot headquarters building with metal-stud construction, a 4,200-square-foot pre-engineered metal maintenance shop with storage mezzanine, demolition of two existing buildings and three sheds, and associated site work including grading, utilities, paving, fencing, and landscaping, with ultimate completion scheduled for May 2, 2028. R2Build also holds a $9.4 million Army Corps of Engineers Los Angeles Field Office contract (awarded October 20, 2025) for construction of a combined pumphouse and substation facility at Long Beach, California, with demolition of the existing structures and completion by October 20, 2027. An earlier $5.5 million award from the Army Corps of Engineers Sacramento District, issued December 15, 2024, covered construction of the Isabella Visitor Center at Lake Isabella, California, completed in May 2026.
Customer concentration is entirely Army Corps of Engineers, with Sacramento District holding two awards ($24.5 million combined potential value) and Los Angeles Field Office holding one ($9.4 million). Combined potential value across all three awards is $33.9 million, fully obligated. Awards have arrived at a rate of one per year across 2024, 2025, and 2026. Two awards totaling $28.4 million in combined potential value face ultimate completion within the next twenty-four months and will therefore enter recompete cycle in that window.
