RK&K

What RK&K does

RK&K (legal name Rummel, Klepper and Kahl, LLP) is a privately held, Maryland-domiciled engineering and infrastructure consulting firm founded in 1923 and headquartered in Baltimore. The firm provides full-service planning, engineering, environmental, and construction management/inspection services across transportation, water/wastewater, structures, traffic, environmental, geotechnical, utilities/energy, tolling, and transit/rail disciplines for public and private sector clients. Service delivery is organized through specialized practice lines including Alternative Delivery (design-build, CMAR, P3), Construction Management, Environmental, GIS, Innovation (3D/4D BIM, AR/VR, drones/UAS, application development), Site Development, Structures, Surveying, Tolling, Traffic/ITS, Transportation, and Utilities/Energy.

The business model is professional services revenue generated through project-based contracts awarded via competitive procurement, RFPs, and qualifications-based selection, primarily with state Departments of Transportation, municipal governments, federal agencies (FHWA, Smithsonian), and select institutional clients (Johns Hopkins, Amtrak, Atlantic Shores Offshore Wind). Multi-year contract cadence and embedded client relationships produce recurring revenue streams tied to federal infrastructure funding (including IIJA-era programs) and state capital plans across the Mid-Atlantic, Southeast, and South Central United States. The firm operates as a limited liability partnership under employee-style ownership with no disclosed private equity or external backing, employs 1,001–5,000 staff, and has been consistently recognized in the Engineering News-Record Top 500 Design Firms. Technical differentiation rests on multi-disciplinary scale, mature government procurement credentials, and an Innovation practice incorporating BIM, AR/VR, and UAS-enabled surveying, though no proprietary AI/ML product is disclosed in available materials.
