AON Consulting, Inc.

AON Consulting, Inc., a foreign-owned for-profit corporation headquartered in Washington, DC, delivers human resources consulting, compensation analysis, personnel testing, and management consulting services to federal agencies as a prime contractor (99% of recent awards), competing exclusively full-and-open with no set-aside designations. The company operates under the General Services Administration's Multiple Award Schedule and specialized consulting vehicles, with a broad customer base spanning thirty federal agencies and a concentrated revenue footprint anchored by two large customers.

Customer concentration is stark and dominated by dollar value rather than award volume. The Department of the Treasury Internal Revenue Service leads both rankings at 144 awards and $274.3 million in combined potential value, but the second-largest customer by dollars — the Pension Benefit Guaranty Corporation — carries only 4 awards worth $179.1 million, indicating that PBGC's work is high-value, high-impact. Together, these two customers account for approximately 80% of AON's combined potential value across 317 total awards. The Department of Justice Federal Bureau of Investigation Headquarters Division ranks third by both metrics at 21 awards and $21.2 million, followed by GSA Federal Acquisition Service (3 awards, $61.9 million) and the Department of Homeland Security Chief Human Capital Officer (2 awards, $9.9 million). The top five customers by dollar value represent 96% of the combined potential value across all awards.

AON's vehicle position is concentrated on the GSA Multiple Award Schedule, which carries 287 task orders worth $312.8 million in combined potential value and accounts for the overwhelming share of AON's federal work. Secondary vehicles include the Professional Services Schedule (71 task orders, $7 million) and specialized BPAs including Human Resources & Equal Employment Opportunity Services (16 task orders, $3.3 million), Actuarial Support Services (3 task orders, $6.1 million), and other smaller purchase vehicles.

Representative capability work reflects AON's focus on federal HR and organizational consulting. Recent prime awards include a $4.74 million Leadership Skills Assessment delivery order under GSA MAS (March 2024, ultimate completion March 2029), a $630,093.75 ADEPT test purchase order supporting FBI's Special Agent Selection System with option year 2 exercised (September 2024, ultimate completion September 2027), a $286,668 USDA Forest Service delivery order for recreation special uses insurance policy review, consulting, and training under GSA MAS (September 2024, ultimate completion September 2029), and a $330,764.08 definitive contract with the Department of Homeland Security's Chief Human Capital Officer for ongoing design, analysis, and operation of the DHS Cybersecurity Compensation System (August 2026, ultimate completion August 2027). The source identifies prior notable work including a $4.8 million FBI leadership assessment contract and a $9.6 million CISA compensation analysis program.

NAICS concentration is split between Administrative Management and General Management Consulting Services (190 awards) and Investigation and Personal Background Check Services (105 awards), with Human Resources Consulting Services (8 awards) and smaller volumes of Facilities Support Services and Other Management Consulting. PSC coding reinforces the mix: Support-Management, Other (135 awards), Support-Professional, Other (53 awards), Education/Training-Personnel Testing (30 awards), and Support-Professional, Human Resources (27 awards).

Activity volume has been flat and low in recent years — two awards in 2022, three in 2023, three in 2024, three in 2025, and two in 2026 — though the source data spans 317 total awards dating back to 2001, indicating that the recent snapshot captures only a portion of AON's lifecycle activity. Combined potential value obligated across all awards is $58.9 million (10% of combined potential value), reflecting that many of the 317 awards remain potential rather than invoiced. AON faces minimal recompete pressure: only two awards with combined potential value of $961 thousand are scheduled for ultimate completion within the next twenty-four months.

SCI-reportable invoicing across federal service contracts above the $150,000 threshold totaled $3.7 million in FY2022–FY2025, delivered by approximately 1.6 to 2.1 FTEs per fiscal year. On federal services contracts captured in SCI, government-paid hourly rates ran around a median of $233.24/hr, with the 10th percentile at $230.34/hr and the 90th percentile at $236.43/hr — a narrow rate band reflecting consistent senior-level pricing. AON's GSA Schedule labor portfolio spans twelve categories ranging from Analyst I at $94.88/hr (bachelor's, one year experience) through Partner-Executive/Strategy at $489.74/hr (master's, ten years experience), with no security-cleared labor offered. Across SCI-reportable prime contracts, AON uses no subcontractors; across four named sub-awards in the source, AON subcontracts to larger FFRDC and national laboratory primes including MIT Lincoln Laboratory, Triad National Security, Honeywell Federal Manufacturing & Technologies, and Pantexas Deterrence on management, operations, and professional services work for Department of Energy and NNSA facilities.
