About the company
Geostabilization International, LLC, a small business based in Westminster, Colorado, delivers slope stabilization, soil nailing, rockfall protection, and embankment repair services to federal land management and transportation agencies as a prime contractor on 98% of recent awards. The vendor operates predominantly full-and-open on the GSA Multiple Award Schedule with no recurring set-aside posture, though individual delivery orders sometimes carry Total Small Business set-aside designations.
Geostabilization International's customer base concentrates on civilian land-management agencies. The top five customer agencies account for 64% of awards by count but only 50% of combined potential value; this divergence reflects the presence of a single large General Services Administration Federal Acquisition Service award valued at $16 million that reshapes the dollars-per-agency distribution. By award count, the Department of Agriculture Forest Service dominates, led by the Southern Region (R8) with 14 awards totaling $3.9 million combined potential value, followed by the Department of the Interior Bureau of Land Management's Oregon-Washington region (10 awards, $3.1 million), the Department of Transportation Federal Highway Administration (6 awards, $2.1 million), and USDA Forest Service's Southwestern Region (R3) and Pacific Northwest Region (R6) rounding out the active set. Recent representative work includes a $1.4 million delivery order from USDA Forest Service Region 3 for the Jacks Creek Road Stabilization Project in Santa Fe, New Mexico (awarded October 2025); a $1.15 million Total Small Business delivery order from USDA Forest Service Region 9 for roadway platform stabilization on Forest Road 19 near Elkins, West Virginia (awarded May 2026); a $811 thousand delivery order from the Federal Highway Administration for embankment slope stabilization along Grand Loop Road in Yellowstone National Park (awarded September 2024); and a $684 thousand order from USDA Forest Service Region 9 for stabilization work at three landslide locations on Forest Road 13 in West Virginia (awarded March 2026).
Geostabilization International places all work through the GSA Multiple Award Schedule, which carries 52 task orders totaling $18.6 million in combined potential value. An Indefinite Delivery Contract (AG4568C050030) contributes 3 task orders worth $711 thousand. Activity has remained modest and stable over five years — ranging from two awards in 2022 and 2023 to four in 2025 and three in 2026 — with only one award (valued at $1.4 million) completing within the next twenty-four months. The vendor operates almost exclusively as a prime (98% of awards); a single sub-award from May 2023 under prime Tucci & Sons LLC involved soil nail retaining wall and drilling services on Stevens Canyon Road at Mount Rainier National Park. Service Contract Inventory data shows negligible SCI-reported invoicing activity (zero across FY2023–FY2025), with minimal FTE trajectory (0.4 FTEs reported in FY2022, declining to zero thereafter), indicating that Geostabilization International's federal footprint is driven by delivery-order work on construction and geotechnical services rather than time-and-materials or labor-hour contracts. The vendor has accumulated $36.3 million in combined potential value across 59 awards since 2005, with $20.1 million obligated (55% of potential), indicating steady but selective execution on geohazard mitigation and slope stabilization projects across western and eastern federal lands.
