Willis Towers Watson US LLC

Willis Towers Watson US LLC, a foreign-owned global consulting firm based in Arlington, Virginia, delivers compensation assessment, benefits administration, human resources consulting, and organizational strategy services to federal agencies as a prime contractor (96% of recent awards) on a full-and-open basis with no set-aside designations. The vendor competes across GSA Schedule vehicles and blanket purchase agreements; recent prime awards include a $402,500 sole-source delivery for Benefit Connect licenses and system support with the Pension Benefit Guaranty Corporation (Sept 2025), a $207,397.50 definitive contract for safety culture and climate survey assistance to the Nuclear Regulatory Commission (Sept 2026), and a $117,810 compensation assessment delivery order with the Treasury Departmental Offices under the Multiple Award Schedule (Sept 2023).

Willis Towers Watson's customer base is dispersed across 27 federal agencies with moderate concentration. The top five agencies by award count account for 48% of recent awards and include the Treasury Office of the Comptroller of the Currency (15 awards, $2 million combined potential value), the Securities and Exchange Commission (13 awards, $3.3 million), and the Consumer Financial Protection Bureau (9 awards, $6 million). By dollar value, however, the top five customers account for 78% of combined potential value, anchored by a $10 million GSA Federal Acquisition Service award, the $8.7 million PBGC work, and the $6 million CFPB portfolio. The two rankings diverge substantially — GSA and PBGC anchor most dollar value but not most award volume — a pattern typical of vendors with a small number of high-value systems or licensing deals alongside a broader portfolio of smaller consulting engagements.

Willis Towers Watson's vehicle position centers on the Multiple Award Schedule (56 task orders, $12.7 million combined potential value) and the Professional Services Schedule (18 task orders, $1.1 million), complemented by single BPA calls and a Federal Supply Schedule position. Activity has remained flat at roughly two awards per year over the past five years; only one award (combined potential value $207 thousand) reaches ultimate completion inside the next twenty-four months, indicating minimal recompete pressure in the near term. The vendor operates almost exclusively as a prime contractor; recent sub work is minimal, routed through Honeywell Federal Manufacturing & Technologies (National Security Campus management and operations reporting, June 2024 and March 2026), ManTech (MIT Lincoln Laboratory operational services consulting, Oct 2024), and Beyond New Horizons (pension planning consulting under Test Operations and Sustainment II, Jan 2025).

SCI-reportable invoicing totaled $1.2 million across FY2023–FY2025 ($382 thousand, $462 thousand, and $382 thousand respectively), with zero FTEs reported across all fiscal years in the dataset — reflecting that Willis Towers Watson's reportable service contracts are knowledge-work deliverables with external labor delivery models rather than staff augmentation. Capability concentration across the portfolio runs heavily to administrative and general management consulting (66 awards), software publishing (7 awards), and human resources consulting (5 awards), with support-professional classification dominating PSC categorization.
