About the company
Tatco LLC, a Native American-owned small business based in Caputa, South Dakota, provides construction, facility renovation, infrastructure maintenance, and specialized trades services to federal agencies serving tribal communities, operating exclusively as a prime contractor under Indian Small Business Economic Enterprise (ISBEE) and total small business set-asides. The company is certified as an Indian Economic Enterprise, Indian Small Business Economic Enterprise, minority-owned business, and self-certified small disadvantaged business; it operates as a Subchapter S Corporation and maintains one named subsidiary, Tatco RC JV, LLC, also minority-owned and Native American-owned.
Tatco's customer concentration is heavily weighted toward the Department of Health and Human Services Indian Health Service, which accounts for 11 awards totaling $19.1 million in combined potential value—42% of the company's total federal footprint. The Department of the Interior's Bureau of Indian Affairs components (Central Office and Bureau of Indian Education) together represent 8 awards worth approximately $1.7 million combined potential value. The Air National Guard anchors the remaining $25 million potential value through a single ten-year multiple-award construction IDIQ awarded April 15, 2026, with a $25 million ceiling covering maintenance, repair, and construction services across South Dakota through April 14, 2036. From the Indian Health Service, Tatco holds a $10 million IDIQ awarded June 1, 2026, under the IHS Nationwide Construction Multiple Award Task Order Contract (MATOC) program running through November 30, 2031, positioned to issue task orders competitively across tribal healthcare facilities nationwide.
Tatco's capability portfolio centers on healthcare facility construction and renovation, facility maintenance, and specialty trades. Representative prime work includes a $4.03 million firm-fixed-price contract with IHS for sewer rehabilitation at Crow/Northern Cheyenne Hospital in Crow Agency, Montana (awarded April 14, 2025, completion June 14, 2026); a $1.68 million renovation of the CT scan room at Blackfeet Hospital in Browning, Montana, for ISBEE set-aside (awarded July 25, 2025, completion November 27, 2026); and a $934,443 contract for life safety upgrades at three IHS healthcare facilities on Pine Ridge Reservation in South Dakota—Kyle Health Center, Wanblee Health Center, and LaCreek District IHS Clinic (awarded July 14, 2025, completion January 25, 2027). Work extends to roofing, fence installation, demolition with hazardous-materials handling, HVAC maintenance, carpet and flooring installation, and fire alarm system replacement and monitoring. Recent awards include a $798,830 delivery order from IHS for abatement, remediation, and restoration at Keams Canyon Quarters in Arizona (awarded September 3, 2026, completion May 5, 2027); a $523,315 roof replacement at Blackfeet Adult Detention Center, Montana (awarded July 28, 2026, completion November 8, 2026); and a $209,986 security fence installation at Rosebud Hospital, South Dakota (awarded April 27, 2026, completion November 30, 2026). Primary NAICS codes are Commercial and Institutional Building Construction (10 awards), with secondary concentration in All Other Specialty Trade Contractors, Flooring Contractors, Roofing Contractors, and HVAC Contractors. PSC concentration aligns with Hospital and Healthcare Construction and Repair, with subset activity in housekeeping and earth-moving equipment.
Award activity has grown sharply: four awards in 2024, eight in 2025, and fourteen through September 2026. Tatco's most recent award dates to September 16, 2026 (four weeks prior to this summary). Combined potential value across all 26 prime awards is $46.8 million, of which $10.9 million (23%) has been obligated to date. Thirteen awards with ultimate completion dates in the next twenty-four months carry combined potential value of $5.8 million and therefore face recompete exposure. The company operates 100% as a prime contractor with no documented subcontract work in the source data. All awards are reserved for ISBEE or total small business set-asides; Tatco does not compete in full-and-open federal procurements. The source shows SAM registration effective April 2024, positioning the company as recently onboarded to federal contracting. Tatco does not hold positions on government-wide vehicles such as GWACs or agency-wide IDIQs beyond the two MATOC vehicles (IHS and Air National Guard) it has been awarded directly.
