About Tatco LLC
Tatco LLC, a Native American-owned small business based in Caputa, South Dakota, delivers construction, facility maintenance, and infrastructure services to federal agencies serving Indian Country as a prime contractor exclusively, competing predominantly under Indian Small Business Economic Enterprise (ISBEE) and total small business set-asides. The firm holds multiple SBA designations: Indian Economic Enterprise, Indian Small Business Economic Enterprise, minority-owned business, and self-certified small disadvantaged business status, operating as a Subchapter S Corporation with a subsidiary, Tatco RC JV LLC, similarly certified across all four designations.
Tatco's customer concentration aligns tightly with its ISBEE posture. The Indian Health Service dominates both award count and dollars (7 awards, $17.1 million combined potential value), anchoring Tatco's portfolio with major healthcare facility infrastructure projects: a $1.6 million CT room renovation at Blackfeet Hospital in Browning, Montana (awarded July 2025, due September 2026); a $4.03 million sewer rehabilitation contract at Crow/Northern Cheyenne Hospital (awarded April 2025, due June 2026); and a $934,443 life safety upgrade project across three Pine Ridge facilities (awarded July 2025, due January 2027). The Department of the Interior's Bureau of Indian Education accounts for three awards totaling $891 thousand, including a $411.2 million chain fence and concrete work contract at Pine Ridge School (awarded August 2024, due July 2025) and a $472.9 thousand track maintenance and goal posts installation at the same school (awarded August 2024, due November 2024). The Air National Guard's single award—a $25 million multiple-award IDIQ for construction, maintenance, and repair services across South Dakota National Guard facilities (awarded April 2026, due April 2036)—represents the largest single award but reflects vehicle capacity rather than typical task-order volume.
The Indian Health Service also placed Tatco on a $10 million multiple-award IDIQ for nationwide IHS construction and facility maintenance services (awarded June 2026, due November 2031), establishing institutional access to task-order flow across tribal healthcare facilities. Additional customers include the Bureau of Indian Affairs (fire alarm system removal and replacement, $54.6 thousand; mini excavator and mulcher procurement, $157 thousand; security fence installation at Rosebud Hospital, $210 thousand), the Bureau of Land Management (dispatch center upgrade at Miles City, Montana, $182 thousand), and the Forest Service (fire alarm system installation at Tatanka Hotshots Base, $54.6 thousand). Three customers account for 76% of awards by count, but the Air National Guard's IDIQ skews potential-value concentration—IHS and interior represent 99% of combined potential value when the Air National Guard's $25 million vehicle is included.
Capability work spans commercial and institutional building construction (7 awards), HVAC and plumbing services (2 awards), flooring and carpet installation (2 awards), and specialty trades including electrical and security systems. Representative examples include multi-door replacement and repair at the Quentin N. Burdick Memorial Health Care Facility in Belcourt, North Dakota ($319.4 thousand, November 2025–July 2026); HVAC maintenance at the Mashpee Service Unit in Massachusetts ($39.4 thousand, active through December 2029); carpet installation at the Main Interior Building in Washington, DC ($122.9 thousand); and interior playground equipment provision and installation at an Air Combat Command facility ($137.5 thousand, September 2024–January 2025). Activity has accelerated—four awards in 2024, eight in 2025, and five year-to-date in 2026—with six awards (combined potential value $3.3 million) reaching ultimate completion within the next twenty-four months and subject to recompete. Combined potential value across all seventeen awards stands at $43.7 million, with $8.2 million obligated to date (19% obligation rate), reflecting the early-stage maturity of several multi-year contracts and the two newly awarded IDIQs carrying ceiling capacity rather than immediate task-order volume.
