Krueck & Sexton Architects, LTD

Krueck & Sexton Architects, LTD, doing business as Krueck Sexton Partners, is a Chicago-based architectural and engineering services firm that delivers worldwide design, master planning, cost estimating, construction documents, and project management services to the U.S. Department of State's Bureau of Overseas Building Operations as a prime contractor exclusively (100% of recent awards), competing on a full-and-open basis with no set-aside designations. The firm is a for-profit Subchapter S corporation operating under NAICS 541310 (Architectural Services) with primary PSC coding in Architect and Engineering services; it holds Secret facility clearance with safeguarding capability required for overseas diplomatic facility work.

Customer concentration is extreme and narrow: the Department of State's Bureau of Overseas Building Operations accounts for 55 of 79 total awards (85% of award count) and $531 million of the combined potential value across a $660.1 million footprint (98% of combined potential value). The ranking by potential dollars diverges significantly from volume — a single GSA Central Office Acquisition Services Division award represents $75 million, and Department of Education, Department of Homeland Security Customs and Border Protection, Social Security Administration, and the Administrative Office of the U.S. Courts round out the remaining customer agencies with small discrete awards. Recent delivery orders exemplify the OBO portfolio: a $8.46 million project development and design services order for Kampala, Uganda (July 2022, completion July 2026); a $1.38 million technical due diligence and concept design order for a lease fit-out in Nukualofa, Kingdom of Tonga (April 2023, completion April 2025); and a $1.25 million project development and design order for Muscat, Oman (September 2025, completion September 2027). Krueck Sexton also holds a $100 million multiple-award indefinite-delivery contract (IDC) with OBO, awarded March 31, 2026, with a one-year period through March 30, 2027 for worldwide architectural and engineering design services at diplomatic and foreign service posts and domestic offices globally. The firm operates under three additional legacy OBO IDCs and GSA Public Buildings Service regional IDCs, placing 30 task orders under the Worldwide Renovation Rehabilitation Design Services vehicle alone.

Ten awards (combined potential value $60.9 million) reach ultimate completion in the next twenty-four months and will face recompete. SCI-reported invoicing totaled $51.2 million across FY2022–FY2025, with FY2024 peaking at $18.8 million across 52.3 FTEs delivered. Government-paid hourly rates on prime SCI contracts run a median of $261.30 per hour, with senior labor pricing reaching the 90th percentile at $563.22 per hour. Across SCI-reportable prime contracts, subcontractors perform approximately 18% of total contractor hours, with 84 named subcontractors reported across the portfolio. The firm builds its own design and project-management delivery teams while leveraging specialized sub-consultants for specialized disciplines; it operates as a prime-only shop with no subcontract work to other federal primes in the source data.
