About the company
Professional Environmental Engineers, Inc., doing business as Professional Environmental Engineers, is a minority-owned, black American-owned, SBA 8(a)-certified and HUBZone-certified small disadvantaged business headquartered in St. Louis, Missouri, that delivers environmental consulting, site assessment, remediation, and construction management services to federal agencies predominantly as a prime contractor on GSA Multiple Award Schedule vehicles and agency-specific IDIQs and BPAs.
The vendor operates as prime on 94% of its federal awards (183 of 195 total awards across all sources) with a concentration in environmental consulting services. Concrete capability portfolio spans Phase I and Phase II environmental site assessments, hazardous materials and contaminant sampling, soil remediation, abandoned mine lands inspections, environmental engineering and assessment (EE/CA) work, construction management and quality assurance services, and pre-acquisition environmental database searches and reporting. Representative prime work includes a $175,176 delivery order from the Office of Policy Management and Budget for Yellowstone Environmental Services in Mammoth, Wyoming (awarded September 2026, running through 2029); a $10 million single-award Indefinite Delivery Contract with the Army Corps of Engineers St. Louis District for construction management services (awarded July 2024, extending through January 2030); a $7 million single-award BPA with the Forest Service Southern Region for environmental consulting across eleven southern states (awarded March 2023, running through 2028); and a $1.2 million GSA BPA established September 2026 for pre-acquisition environmental database searches supporting USDA Natural Resource Conservation Services nationwide. GSA Schedule labor rates span $45.69 to $160.76 per hour across 38 categories, covering administrative and technical roles (Administrative Assistant I, Technical Editor, Site Superintendent) through senior specialist positions (Geologist III, Program Manager) with education requirements from associate through master's degree; no security-cleared labor is offered.
Customer concentration concentrates heavily on the Army Corps of Engineers. The top five funding agencies by award count account for 44% of all awards: the Army Corps of Engineers Engineering District Louisville (25 awards, $14.5 million combined potential value), the National Oceanic and Atmospheric Administration (20 awards, $156 thousand combined potential value), the Army Corps of Engineers (14 awards, $17.6 million), the Army Corps of Engineers Engineering District St. Louis (14 awards, $12.9 million), and the Department of the Interior National Park Service Pacific West Region (13 awards, $1.4 million). By combined potential value, the GSA Federal Acquisition Service dominates (3 awards, $101.9 million) due to the vendor's Multiple Award Schedule vehicle position; the Army Corps of Engineers commands four of the next five top-value customers. The vendor serves 42 distinct federal agencies across the total award population, indicating diversification beyond the top five.
Professional Environmental Engineers places work against the Multiple Award Schedule (75 task orders, $16.8 million combined potential value), Federal Supply Schedule GS10F0184P (19 task orders, $2.2 million), The Professional Services Schedule (17 task orders, $147 thousand), and multiple Army Corps of Engineers IDIQs including Indefinite Delivery Contract W912QR08D0025 (16 task orders, $4.6 million) and EPS70515 (10 task orders, $350 thousand). The vendor also holds the $10 million Army Corps of Engineers St. Louis District IDIQ for construction management and the $7 million Forest Service Southern Region BPA, both single-award vehicles positioning it as a locked-in incumbent for task-order activity in those agencies' environmental and construction portfolios.
Activity trajectory shows stable volume in recent years—five awards in 2022, eight in 2023, fourteen in 2024, eight in 2025, and eight in 2026—without pronounced growth but consistent presence. Recompete exposure is minimal: only two awards (combined potential value $254 thousand) face ultimate completion within the next twenty-four months, indicating a stable forward pipeline with limited incumbent-recompete risk in that window. Combined potential value across all 195 awards totals $208.4 million, with $31.2 million obligated to date (15% of combined potential), reflecting a mix of small task orders and large IDV ceilings typical of GSA Schedule and agency IDIQ vehicles.
As a subcontractor, Professional Environmental Engineers supplies technical assistance and labor to Tetra Tech, Inc. on Superfund Technical Assessment and Response Team (START) regional contract work, with two documented sub-awards in Regions 5 and 7 for EPA emergency response support (August 2025 and November 2024). The vendor also receives sub-award flow from the Kansas Department of Health and Environment on federal brownfields and remediation grants, with multiple Phase I assessments and encumbrances dating from late 2023 through mid-2026. Service Contract Inventory data shows minimal SCI-reportable activity (5 records, all subcontractor roles) spanning FY2022–FY2025, with 0.8 to 1.3 FTEs per year on named subs—a reflection that the vendor's primary revenue channel runs through GSA Schedule and IDIQ delivery orders rather than SCI-captured service contracts.
Corporate structure includes four minority-owned, small disadvantaged business joint ventures: Pe Ayuda Joint Venture LLC, Pe Ayuda Environmental Solutions JV LLC, Pe-Metric Joint Venture LLC, and Pe-WCE Joint Venture LLC. All four are black American-owned or DOT-certified DBE structures, positioned to enable team captures and set-aside opportunities requiring joint-venture partnerships. Set-aside posture reflects the vendor's 8(a) and HUBZone certification: the majority of awards carry either Total Small Business or no explicit set-aside designation, with competitive 8(a) and sole-source 8(a) designations present across the historical portfolio. The vendor competes on full-and-open vehicles (GSA MAS, BPAs) and agency IDIQs where its small business certifications enable preferential evaluation, rather than limiting itself to 8(a)-reserved vehicles exclusively.
