Alta Science & Engineering Inc.

Alta Science & Engineering Inc., a HUBZone-certified small disadvantaged business based in Kellogg, Idaho, provides architectural and engineering services—including trail design, bridge engineering, environmental assessments, infrastructure rehabilitation, and mining remediation—to federal land management and environmental agencies exclusively as a prime contractor on indefinite-delivery vehicles and delivery orders.

Alta competes entirely in the Total Small Business set-aside posture across its prime footprint and operates as a subsidiary of Terragraphics Environmental Engineering Inc., itself HUBZone-certified. The vendor's federal customer base is heavily concentrated in the Pacific Northwest and Mountain West. The Department of Agriculture Forest Service Region 6 (Oregon and Washington) dominates by award count and dollar value, accounting for nine awards totaling $33.2 million of the $111.6 million combined potential value across all nineteen prime awards. Three Department of the Interior Fish and Wildlife Service Region 1 awards add $670 thousand. However, the two largest single awards—both recently awarded in February 2026—are single-award indefinite-delivery contracts with the EPA: a $25.2 million REPA VII vehicle for EPA Region 9 (running through February 1, 2031) and a $1.4 million REPA VII vehicle for EPA Region 8 (running through February 1, 2031). Together, these two EPA contracts represent 71% of Alta's combined potential value on the source record. The Department of the Interior Fish and Wildlife Service Region 9 (Headquarters) added one award on this scale as well.

Alta's primary parent vehicle is the Department of the Interior Architecture and Engineering Services MATOC 2022-2027, a $50 million multiple-award contract running through September 30, 2027, under which Alta has placed seven task orders totaling $1.6 million. Representative work under this vehicle includes a $368,850 alternative analysis for Magic Valley Fish Hatchery (Filer, Idaho; awarded September 24, 2024; completion December 31, 2025), a $278,596 schematic design contract for Upper Carson Slough Backcountry Trail System at Ash Meadows National Wildlife Refuge, Nevada (awarded January 27, 2023; completion August 5, 2025), and a $197,269 order for engineering and design of two prefabricated steel trail bridges in Winthrop, Washington (awarded May 5, 2023; completed April 30, 2024). Alta also holds a position on the Department of Agriculture Forest Service PPS NWZ Architecture and Engineering multiple-award IDIQ ($25 million ceiling, awarded September 22, 2025, running through September 20, 2030) for professional architect-engineer services across Transportation, Facilities, and Environmental disciplines in Forest Service Regions 6 and 10.

Alta also placed six task orders under the Mine Reclamation Services for Regions 6 and 10 vehicle, totaling $1 million combined potential value, including annual monitoring and gamma survey work at the White King/Lucky Lass CERCLA site in Lakeview, Oregon. Only three awards face ultimate completion within the next twenty-four months, carrying combined potential value of $714 thousand, leaving Alta with minimal recompete exposure in that window. The two EPA REPA VII contracts are anchored through February 2031, creating a stable multi-year revenue base if task orders are issued against the ceilings.

Service Contract Inventory data is sparse for Alta: only three SCI records spanning FY2022 through FY2024, covering one prime and one sub-hour record, with no reportable invoiced revenue on prime contracts and 1.6 FTEs delivered in FY2024. SCI is a partial federal services view and does not capture Alta's full federal delivery footprint, which centers on fixed-price delivery orders and design-phase task orders under architecture-engineering vehicles.

Originally started in 1984 as a business division within a larger company, Alta was officially established through a corporate reorganization and split off in 2017.
