About Stell Environmental Enterprises Inc.

Written by GovTribe AI ·

Stell Environmental Enterprises Inc., doing business as Stell, is a Mountlake Terrace, Washington–based woman-owned and service-disabled veteran-owned small business that delivers cultural resource management, environmental consulting, and archaeological survey services to federal agencies as a prime contractor on over 99% of its awards. Stell holds SBA 8(a), economically disadvantaged woman-owned small business (EDWOSB), woman-owned small business (WOSB), and veteran-owned small business (VOSB) certifications, all expiring February 25, 2028, and competes predominantly under small business set-asides across its federal footprint.

Stell's federal customer base concentrates heavily in the Army Corps of Engineers system. The top five customers by combined potential value account for 79% of the vendor's $1.19 billion portfolio: the Army Corps of Engineers Engineering District Mobile (26 awards, $660.9 million potential value) anchors the portfolio, followed by headquarters-level Army Corps of Engineers awards (17 awards, $93.3 million), the Seattle District (11 awards, $77.5 million), the Albuquerque District (8 awards, $60.9 million), and the Fort Worth District (44 awards, $44.2 million). A concentration split emerges between volume and dollars: Fort Worth places the most awards by count (44) but represents just $44.2 million, while Mobile's 26 awards carry $660.9 million—a twenty-five-fold difference reflecting large architect-engineer and planning services IDIQs anchored there. Navy Installations Command (17 awards) rounds out the top five by count but carries only $3 million in potential value.

Stell's capability portfolio centers on archaeological surveys, cultural resource inventories (Classes I and III), environmental impact assessments, wetland delineations, ethnographic studies, and compliance consulting—work reflected in the top NAICS and PSC codes. Engineering Services (113 awards), Environmental Consulting Services (98 awards), and Remediation Services (41 awards) form the NAICS backbone. Architect and Engineering services (78 awards), Other Environmental Services (51 awards), and archaeological and paleontological studies (38 awards) dominate the PSC profile. Representative named work includes a $660.9 million multiple-award architect-engineer IDIQ for the Mobile District (through December 2029) covering environmental compliance, planning, conservation, NEPA, environmental studies, master planning, and restoration/remediation design across the southeastern U.S. and other domestic and international locations; a $249 million multiple-award A-E IDIQ (also Mobile District, through December 2029) for Planning and Environmental Division support; a $40 million woman-owned small business cultural resources IDIQ across three regional centers (through May 2031); a $45 million WOSB environmental consulting IDIQ with the Seattle District (through March 2029); and a $15 million NIST architectural services IDIQ for master planning and associated studies (through July 2027). On the task-order side, Stell has delivered $12.6 million in REM Services and IMCOM sustainment work to the Engineering Support Center Huntsville (through September 2029), $7.8 million in Air Force Community Partnership support (through June 2026), $8 million in Air Force Community Partnership and Encroachment Management work (through March 2025), and numerous cultural resource surveys in the $50 thousand to $1.1 million range across BLM, Forest Service, and Fish and Wildlife Service.

Stell holds seat on five major parent vehicles capturing its largest task-order flows. Indefinite Delivery Contract W9126G06D0037 (33 task orders, $9.8 million combined potential value) supports core A-E work; N6247012D7002 (Navy, 26 task orders, $3.9 million) anchors Navy work; W9127811D0018 and W9127816D0007 (15 and 19 task orders respectively, $4.6 million and $14.8 million) capture Army Corps MATOC activity; Blanket Purchase Agreement 1240BE21A0025 (12 task orders, $2.3 million) covers Forest Service cultural heritage services. Stell also positions on the GSA Multiple Award Schedule with 19 labor categories spanning Environmental Scientist, Archaeologist, GIS Specialist, Engineer, Military Planner, and Program Manager at hourly rates from $74.33 to $257.56, all requiring a bachelor's degree and no security clearance.

Activity has declined recently—from 19 awards in 2023 to 16 in 2024, 9 in 2025, and 5 through June 2026. Only 8 awards carrying $2.7 million in combined potential value face ultimate completion within the next twenty-four months, limiting near-term recompete exposure. Service Contract Inventory reporting shows minimal federal services footprint: $664 thousand in invoiced dollars across FY2023–FY2024 (3.4 FTEs in FY2023, 3.4 FTEs in FY2024) at a government-paid median hourly rate of $54.63/hr, 10th percentile $14.01/hr, 90th percentile $80.09/hr. Stell operates as a prime on 99% of awards and subcontracts to minimal depth: across SCI-reportable prime contracts, subs performed just 2% of total hours, with one named subcontractor reported. Named sub awards include archaeological evaluation staffing and QC work under Marstel-Day on a National Historic Site project, NEPA environmental consulting to Weston Solutions for a Coast Guard air station mooring project, and energy and water benchmarking services to Leidos through September 2026. Stell's set-aside posture is consistent across both prime and sub roles—8(a) and WOSB set-asides recur heavily in prime awards, and the vendor competes total-small-business and woman-owned set-aside vehicles as a characteristic posture rather than full-and-open competition.
