Charles YOE

Charles YOE, a sole proprietorship consulting firm based in Catonsville, Maryland, provides expert technical consulting and peer review services to federal agencies as both a prime contractor (33% of recent awards) and as a subcontractor (67%), competing without small business set-asides on full-and-open procurements. The vendor has been registered with SAM.gov since 2004 and operates in management consulting and scientific-technical advisory roles under NAICS 541611 and 541690.

Charles YOE's customer base concentrates entirely on the Department of the Army Corps of Engineers, which accounts for 100% of recent awards. The Corps of Engineers' Engineering District Chicago has placed two prime purchase orders and four subcontract task orders with the vendor since November 2023. Prime work includes a $15,820 firm fixed-price purchase order awarded March 23, 2026, for expert panel review services supporting the GLRI Model Framework, with performance at Catonsville through March 22, 2027, and a $9,994 purchase order awarded September 15, 2025, for expert peer review under the GLCRS Task 3.6 initiative. Four task orders flow through the Water Resources Analytical and Professional Support Services parent vehicle, which serves as the sole procurement channel in the vendor's footprint.

Activity has remained modest and episodic—one award in 2023, one in 2024, two in 2025, and two in 2026—with combined potential value across all six awards standing at $26 thousand. Notably, obligated dollars ($217 thousand) exceed combined potential value by a factor of eight, indicating that actual invoiced work has substantially outpaced ceiling values on individual purchase orders. One award ($16 thousand combined potential value) reaches ultimate completion within the next twenty-four months and faces recompete. As a subcontractor, Charles YOE works exclusively under CDM Federal Programs Corporation on consulting task orders for the Corps, including "Comprehensive Benefits GPS" advisory services (February 2026 and November 2023), OSE Metrics support (December 2025), and risk analysis training support (February 2024). The vendor's footprint is narrow geographically and functionally—all work is performed in Maryland, all customer contact is Corps of Engineers, and all engagement is in the consulting and technical advisory role. There is no evidence of prime-contract relationships with other agencies, GWAC seats, BPA participation outside the Corps vehicle, or work beyond the water resources and environmental management domains.
