About the company
Sierrita Mining & Ranching Company LP, a self-certified small disadvantaged business based in Sahuarita, Arizona, delivers civil construction, heavy equipment operations, and facilities maintenance services to federal agencies as a prime contractor, with no subcontractor footprint in the federal space. The firm is a for-profit limited liability partnership competing exclusively under full-and-open solicitations with no set-aside designations across its prime awards.
Sierrita's customer base is heavily concentrated with the Smithsonian Institution, which accounts for 42 of the vendor's 80 federal awards (52.5% by count) and $15 million of the $15.2 million combined potential value across all awards — effectively 99% of Sierrita's federal revenue. Work for the Smithsonian centers on civil construction and facilities maintenance at the agency's Arizona properties, particularly in and around Amado, Arizona. Representative Smithsonian work includes a $2.84 million firm fixed-price delivery order awarded in September 2021 for replacement of guardrails and culverts on Mount Hopkins Road (completion scheduled through December 2027), a $548,268 delivery order issued in April 2026 for mountain road improvement, and an $85,038 delivery order from May 2026 for repair of the Aspen Tank retaining wall. The remaining 30 awards to the Occupational Safety and Health Review Commission and single awards to the Department of Agriculture Forest Service, Department of Commerce NOAA, and Department of the Interior Bureau of Land Management contribute negligible value. Sierrita operates under three primary indefinite delivery contracts with the Smithsonian: IDC F17CC10255 (4 task orders, $7.1 million combined potential value), IDC F0436CC10223 (11 task orders, $4.1 million), and IDC 33330221DF0010265 (3 task orders, $3.5 million).
Activity has been sparse and episodic — two awards in 2026, one in 2023, one in 2022, and two in 2021 — with only one award ($2.84 million) facing completion inside the next twenty-four months. Primary service categories span commercial and institutional building construction (27 awards), heavy and civil engineering construction (6 awards), and highway and bridge construction (4 awards).
